3D Scanners

Reverse Engineering Using 3D Scanners to Generate CAD Models

The engineers of today lives and thrives in a 3D CAD model world. The CAD models offer the best design versatility and a direct link to rapid prototype development. The CAD models are essential where reverse engineering use 3D scan data to generate CAD models.

Here, the object exhibits a complex shape when using a 3D model that does not exist for a component. The 3D scan equipment captures the physical geometry that transforms it into a 3D digital model. The CAD engineers and industrial designers create a task to adapt and maintain parts that integrate into the design.

Reverse Engineering Features:

  • Designing a new part to fit a legacy part.
  • Obtain CAD data that captures an object’s design intent.
  • It accurately offers performance surfaces.
  • It helps in updating CAD models of your tooling to match shop-floor changes.
  • Get ready to redesign a part without manufacturing defects.
  • It supports modernising your manufacturing process.
  • It offers animation or visualisation.
  • Perform a dimensional along with comparative analysis of an object.
  • Performing FEA or CFD analysis.

Reconstruct the damaged part digitally to reproduce it in its originally intended form. It uses rapid prototyping or CNC technologies. The 3D scanning technologies come in different shapes and forms. Additionally, some stationaries require the part to be brought into the scanner.

The scanning laser technology has conducted surveys of the 3D contour of the surface. It helps to save the geometrical data to a CAD model. The 3D scanners scan vehicles, aeroplanes, ships, submarines, historic monuments, buildings, sculptures, consumer products, and more.

Let’s say a complex 3D scanning problem is the 3D scan that is performed by Creaform, mainly using HandyScan3D. It’s a unit combined with a long-range scanner in the United States Marine Corps War Memorial replica. It is located at the Marine Corps Recruit Depot in South Carolina.

The project’s primary purpose comes with historical preservation so that the memorial could recreate in the future if it suffers damage. The handheld scanner mostly used the application capable of scanning ½ million points per second. With up to 30 sq. resolution accuracy and 60 sq. volumetric accuracies.

HOW DO 3D SCANNERS WORK?

Laser scanning is a process where the scan passes a laser line over the surface of an object. Later the surface data was captured by a camera sensor mounted in the laser scanning. It records and saves three-dimensional information to a model.

The regions of an object are scanned once. It allows thousands of closely positioned points to be surveyed at once. Currently, several laser scanners exist, including the line, patch, and spherical. Also, Laser scanning is performed without making contact with the object.

Talking about digitising, it’s a contact-based form of 3D scanning in which a point or ball probe is scanned over points on the object’s surface. It is more accurate for industrial reverse engineering applications. The 3D laser scanning is more desirable for non-standard or organic shapes where the sculptures or person’s face is scanned. Digitising limits to smaller objects, while 3D laser scanning is more versatile.

It is used to scan large objects like vehicles or buildings. White light scanning, CT scanning and photo image-based systems are mainly used as alternate methods for 3D scanning applications.

LIMITATIONS OF 3D SCANNING

Bright white light sources can be detrimental to 3D scanning technologies, requiring many outdoor laser scanning projects to be conducted after daylight hours.

3D scanning works better on matte finishes than highly reflective surfaces, which reflect white light. Spray-on solutions exist that can effectively dull a surface before scanning.

Some intricate objects, such as large sculptures, require stationary and handheld scanners to reconstruct the entire surface. This process requires a detailed and intricate image and position registration – fortunately, many companies exist that have mastered this process and provide solutions for these complex problems.

INSPECTION WITH USING 3D SCANNING TECHNOLOGIES

Inspection is another valuable use of 3D scanners. It allows parts to be rapidly checked and ensures manufacturing tolerances. 3D scanning technologies use First Article Inspection, where high accuracy comes with fine resolution. It requires verification with a physical part that produces according to production drawings.

The scanners inspect a “final” part so that its models and drawings can generate blueprints for re-manufacturing a part. The Inspection of aging components or systems is possibly used with technologies. For example, modifications are required to update the vehicle in foraging ships or aircraft. It uses reverse engineering that uses laser-based 3d scanning technologies that produce physical dimensions of the vehicle or its parts.

It comes with a prime example that comes with reverse engineering. It comes with an F-15 test plane used for NASA engineers. It was conducted by Direct Dimensions, Inc. (DDI) in 2006. Additionally, the engineers at NASA modify the test plane and obtain in-flight data to verify design improvements.

Due to its daunting costs, it associates along with full-scale testing. It comes with the danger associated with measuring pressure on a plane that moves at supersonic speeds. It is used to chase planes with the help of reverse engineering. Before testing and implementation, it could simulate the design changes and use computational fluid dynamics (CFD) software. DDI mainly uses the FARO LS 3D laser system, along with a portable scanner designed for scanning the shape of large objects.

It can acquire up to 120,000 points per second over ranges of up to 80 meters. The technology allows DDI and quick and accurately capturing the jet’s exterior shape with an accuracy of +/-6 millimeters. The raw comes with 3D scanning data that offer a high-resolution point cloud. It uses a laser that reflects spots off the plane’s surfaces. It can digitally process and convert to CAD format. Over 50 individual scans from different positions generated 50 million data points used in reverse-engineering of the F-15.

What are 3D scanners used for?

3D scanners are used in a variety of fields for capturing the three-dimensional shape and appearance of real-world objects or environments. Here are some common uses:
Industrial Design and Manufacturing: In product design and manufacturing, 3D scanners are used for quality control, reverse engineering, and prototyping. They can capture precise measurements and detailed geometry of physical objects, allowing manufacturers to replicate or modify existing designs or create new ones.
Archaeology and Cultural Heritage: Archaeologists and historians use 3D scanners to document and preserve artifacts, sculptures, and historical sites. By creating digital replicas, researchers can study these objects without risking damage to the originals. Additionally, 3D scanning technology aids in the restoration and conservation of cultural heritage sites and artworks.
Medical Imaging and Healthcare: In medicine, 3D scanners are utilized for various purposes, including custom prosthetics and orthotics, dental applications (such as creating dental crowns and implants), and surgical planning. Medical professionals can capture detailed anatomical data to assist in diagnosis, treatment planning, and patient care.

What is a 3D digital scanner?

A 3D digital scanner is a device used to capture the three-dimensional shape and appearance of real-world objects or environments and create digital representations of them. These scanners use various technologies and methods to collect data points from the surface of the object and then process this information to generate a 3D model.
There are several types of 3D digital scanners, including:
Laser Scanners: These scanners emit laser beams onto the object’s surface and measure the reflections to determine its shape and contours. Laser scanners can capture highly accurate and detailed 3D data, making them suitable for applications such as industrial design and manufacturing.
Structured Light Scanners: Structured light scanners project a pattern of light onto the object and use cameras to capture how the pattern deforms on its surface. By analyzing these deformations, the scanner can calculate the object’s 3D geometry. Structured light scanners are often used in applications like 3D printing, animation, and medical imaging.
Photogrammetry Systems: Photogrammetry involves taking multiple photographs of an object from different angles and then using specialized software to analyze the images and reconstruct the object’s 3D shape. Photogrammetry systems are versatile and can be used with standard digital cameras, making them accessible for various applications, including archaeology, cultural heritage preservation, and virtual reality content creation.
Time-of-Flight (ToF) Scanners: ToF scanners use infrared light to measure the distance between the scanner and the object’s surface. By measuring the time it takes for the light to travel to the object and back, the scanner can create a depth map of the object’s surface, which can then be used to generate a 3D model.

CAD Platforms in Product Designs

CAD Platforms in Product Designs

In the present age of rapidly computerized applications and CAD product designs, it is very likely that many future electromechanical products will have an embedded processor within them. Consider these two examples:

  • Several decades ago, the automobile industry designed automobiles with carburetion technology. This was been replaced by computer-driven electronic ignition systems. Likewise, manual braking was replaced by computer-assisted “antilock braking.” Recently, the concept of a computer-operated driverless car was mentioned as becoming a real possibility. The idea is not too far-fetched when you consider that computer-managed aeroplane navigation is a mature technology.
  • Many products such as copying machines, refrigerators, HVAC systems, and robotic systems provide real-time electronic communication between the customer and the manufacturer. For example, downtime for copying machines is significantly reduced because the product is proactive in sensing impending failures and calling for service. This makes the customer believe that the product is very reliable and virtually failure-free.

These two examples illustrate the trend in product development which combines CAD hardware design, embedded computer technology, and IT (Information Technology) into a package which changes a “dumb product” into a “smart product”. A smart product, therefore, communicates with both its manufacturer and with its customer in a manner which improves the functionality of the product and provides optimum performance of the product.

Best Importance of CAD Platforms in product designs Service

Computer-Aided Design (CAD) platforms play a crucial role in modern product design and development processes. Their importance stems from the numerous advantages they offer, which significantly enhance the efficiency, accuracy, and overall quality of the design process. Here are some key reasons why CAD platforms are essential in product design:

  1. Visualization and Conceptualization: CAD software allows designers to create detailed and realistic 3D models of products.

This is crucial for ensuring that components fit together properly, align with industry standards, and function as intended. Accurate measurements also help in manufacturing and assembly processes.
  4. Collaboration and Communication: CAD platforms facilitate collaboration among cross-functional teams, including designers, engineers, manufacturers, and stakeholders. Designs can be easily shared and reviewed, leading to better communication and alignment among team members, even if they are geographically dispersed.
  5. Simulation and Analysis: Many CAD tools offer simulation and analysis features that allow designers to test how a product will perform under different conditions. This can include stress analysis, fluid dynamics, thermal simulations, and more. Identifying potential issues and optimizing designs early in the process reduces the likelihood of costly redesigns and failures later on.
  6. Reduced Time-to-Market: The use of CAD platforms accelerates the product development timeline. By streamlining design processes, minimizing errors, and enabling parallel workflows (such as design and analysis simultaneously), CAD tools contribute to faster product development and a reduced time-to-market.
  7. Cost Savings: CAD platforms help identify design flaws, interferences, and other issues early in the design phase. By catching these problems before physical prototypes are built or production begins, companies can avoid costly rework, material waste, and potential recalls.
  8. Customization and Personalization: CAD tools facilitate the creation of customized and personalized products. Designers can easily modify designs to meet individual customer needs, leading to more customer satisfaction and market competitiveness.
  9. Documentation and Manufacturing Support: CAD software generates detailed design documentation, including engineering drawings, specifications, and assembly instructions. This documentation is essential for communicating design intent to manufacturers and suppliers, ensuring consistent production quality.
  10. Long-Term Maintenance and Updates: CAD files serve as a digital record of the product’s design and can be used for future modifications, updates, or maintenance. This is particularly valuable for products with long lifecycles or those that require periodic design improvements.

In summary, CAD platforms are indispensable tools that enhance the entire product design and development process, from initial concept to final production. They contribute to improved design quality, faster development cycles, reduced costs, and better collaboration across multidisciplinary teams.

It covers automotive, aerospace, and biomedical. Let’s say a tool that helps civil engineers, city planners, and construction crew to plan out networks for water distribution and wastewater management operations using a single mouse click. Such tools are readily available today and assist us in complex optimizations.

CAD Modeling helping

If we talk about network engineering, then they are a design of pressurized pipelines that is highly complex and require significant planning and understanding. It helps in regulations and design criteria. It is a highly time-consuming task that requires significant effort and prior knowledge with time.

Even with prior understanding, it offers cumbersome to meet the necessary design criteria. It includes a minimum pipeline slope, spacing between valves, and intersection with existing utilities. Along with adding other applicable quality standards to it.

DESIGN AND OPTIMISATION TOOLS FOR BETTER WATER INFRASTRUCTURE

Consider that your design comes with a water network along with a bottom-up approach. It uses the available water source and adds information on the constituent and tank-mixing in the design. Also, in such a scenario, the common questions might be:

  • How would the water system handle a fire?
  • What is the limitation of design in your water network?
  • Will there be enough water at each fire hydrant?
  • What happens if there comes excess flow from a particular location?
  • Will there be a sufficient flow of water that handles your system requirements?

CAD Modeling helping

The CAD programs use 3D modelling designed with complex water distribution systems. It provides the answer to the above questions. Bentley System’s Water GEMS runs a stand-alone tool with MicroStation or AutoCAD tools. The Pipe Plan and Innovyze’sInfoWate tools offer a similar solution to it. The above tools are adopted by utility companies, municipalities, townships, and design engineers. They provide efficient design and optimization tools for water infrastructure and networks.

What are the advantages of using CAD to develop water distribution networks?

  • It comes with the ability to visualise the network in a 3D environment.
  • It offers the ability to model pipe pressures.
  • It helps in GPS tagging of the pipe network and existing pipes.
  • It allows designers to determine points of interference and avoid critical problem areas.
  • It has the ability to model-flow rate, loss nodes and pressures.
  • It is mainly used to design for high-flow conditions at a fire, which requires fire hydrants.

CAD REAL-TIME EXAMPLES AND ITS USE IN WATER DISTRIBUTION NETWORKS

The CAD tools are most likely to be used in civil engineering planning and design. Salt Lake City is used in Utah, and Huntington Beach in California are the two cities that have adopted WaterGEMS software for designing, optimising, and maintaining their water distribution networks. Salt Lake City’s water distribution network helps to serve almost half a million residents, including over 1,000 miles of pipes.

It uses a complete geographical information system (GIS) for its water, sewer, and stormwater infrastructure. It is built into a model. It primarily uses WaterGEMS, a city currently building a hydraulic model for the water distribution system. It primarily uses existing data to update and maintain the city’s expansion.

The tool mainly determines the optimal pipes that replace pipes. Some customers complained that the flow was insufficient during peak periods. They use guidance where the city can remediate the complaints. Further, they meet the fire department’s flow requirement with 1500 gallons per minute for all fire hydrants along with high pressure.

How to do CAD Modelling?

CAD (Computer-Aided Design) modeling involves using specialized software to create detailed digital representations of objects, components, buildings, or systems in a virtual environment. Here’s a general overview of the steps involved in CAD modeling:
Select CAD Software: Choose a CAD software program that suits your needs and the requirements of your project. Popular CAD software options include AutoCAD, SolidWorks, Autodesk Inventor, CATIA, and Fusion 360, among others. Consider factors such as features, compatibility, ease of use, and cost when selecting software.
Create a New File: Start a new project or file in your chosen CAD software. Set up the file with the appropriate units of measurement and any other project-specific settings.
Sketch Geometry: Begin by sketching the basic geometry of the object or component you want to model. Use tools such as lines, circles, arcs, rectangles, and polygons to create 2D sketches that represent the shape and dimensions of your design.
Apply Constraints and Dimensions: Apply geometric constraints (e.g., parallel, perpendicular, concentric) and dimensions to your sketches to ensure they meet design requirements and remain fully defined. Constraints and dimensions help maintain the parametric nature of the model, allowing you to make changes later in the design process.
Create Features: Use a variety of modeling tools to create 3D features from your 2D sketches. Common features include extrusions, revolves, sweeps, lofts, fillets, chamfers, holes, and patterns. These features add depth and complexity to your model and allow you to represent real-world objects more accurately.
Refine and Modify: Refine your model by adding detail, adjusting dimensions, and making modifications as needed. Use editing tools to move, rotate, scale, or delete geometry, and apply modifications to individual features or the entire model.
Assemble Components (if applicable): If your design involves multiple parts or components, use assembly features to bring them together in a virtual assembly. Position, align, and constrain components relative to each other to create an accurate representation of the final product or system.
Check for Errors: Use built-in analysis tools or add-ons to check your model for errors, such as gaps, overlaps, or interference between components. Fix any issues to ensure the model is structurally sound and manufacturable.
Document and Annotate: Add annotations, dimensions, labels, and other documentation to your model to communicate design intent and provide information for manufacturing, assembly, and inspection purposes.
Export or Share: Once your CAD model is complete, you can export it in various file formats for sharing, collaboration, or further processing. Common file formats include .dwg, .step, .iges, .stl, and .pdf.

CAD in Product Development

CAD in Product Development – CAD and CAM are industrial computer applications, which have greatly reduced the time and cost cycles between initial concepts and product development. They have enabled designers and manufacturers to make significant cost savings. These tools also reduce the time to market for new products, and reduce the number of design flaws, which tend to hamper productivity, and in some cases ground an entire production cycle. Since the 1980s, CAD and CAM have provided exponential gains to both the quantity and quality of products.[/fusion_text][fusion_text]The primary advantages of CAD include the ability to:

  • reduce design cycle times
  • design a complex machine without the need to prototype
  • prototype parts directly from a CAD model
  • reduce low-cost design iterations rapidly
  • alter the designs quickly by changing geometrical parameters
  • view designs or parts under a variety of representations
  • virtually simulate real-world applications

CAM is the use of CAD data to control automated machinery for producing parts designed using CAD. The benefits of linking part fabrication directly to the CAD model include:

  • Direct control of computer numerical control (CNC) or direct numerical control (DNC) systems to produce exact replicas of the designs
  • Ability to skip the engineering drawing phase
  • Reduced part variability

How Boeing Set the Standard for Design Automation? – Cad Importance in Product Development –

Boeing is the world’s second-largest defence contractor and a leading manufacturer of aircraft, rockets, and satellites. CAD has played a major role in their product development planning and operations over the past three decades. Boeing announced the development of the 777 in the late 1980s, leading many aviation experts to question their decision. The design of an entirely new aircraft is a highly expensive task, whereas the success of the 747 models had been serving customers for over 30 years led experts to believe that the proper solution was to modify the 747 to suit passenger needs. Boeing applied a new approach that included customer inputs in the design phase from several major airlines, including United Airlines, Nippon Airways, British Airways, Japan Airlines and Cathay Pacific.

More importantly, Boeing invested over $1 billion in design automation using CAD based on CATIA (Computer Aided Three-dimensional Interactive Application) and ELFINI (Finite Element Analysis System) to design the new airliner that would turn out to become an industry standard. Both of these software packages were developed by Dassault Systemes of France. Boeing applied the following objectives to guide their break-through process:

  • Reduce aircraft development time significantly
  • Meet customer requirements better by involving them in the development process
  • Eliminate costly modification procedures

As a result, the 777 was the first aircraft in the world to be designed entirely using CAD technology. It was designed to maximize efficiency and quality. The completed design included over 3 million parts! The design process, its innovative features, and Boeing’s approach to manufacturing became the “Gold Standard” for development of future aircraft and were applied to a number of other projects, such as the International Space Station. The design was executed so successfully that a full-scale mock-up of the 777 was never built and was not necessary, reducing the design and production time. In fact, its first flight was so successful that the design was considered one of the most seamless and smoothest to date.

By using CAD models, design engineers were able to provide “built-in” options, which did not need to go to production, such as folding wing-tips. By developing options in CAD, the cost associated with such a trade study and its design is minimized.

What Benefits did Boeing Realize by Automating its Design Process? – Cad Importance in Product Development –

To assess the value of the design automation that Boeing implemented in their process by using 3D CAD modelling to design the 777, Boeing compared the effort with their previous design efforts (757 and 767). Overall, they realized:

  • 91% reduction in development time
  • 71% reduction in labour costs
  • Over 3000 assembly interfaces were developed virtually without the need for prototypes
  • Reduction in design and production flaws, mismatches, and associated errors
  • 90% reduction in engineering change requests from approximately 6000 to 600
  • 50% reduction in cycle time for engineering change request
  • 90% reduction in material rework
  • 50 times improvement in assembly tolerances for the fuselage.

It is notable that the design was completed at a time when CAD was not linked directly with FEA and CFD modelling software, but the effort has still been widely accepted as one of the greatest uses of CAD of its time.

Importance of CAD in Product Development

The value of CAD modelling is just as valuable on a smaller scale, such as in the bicycle industry. For example, Cannondale is another pioneer that has utilized CAD and CAM technology since the 1990s to reduce its production cycle and reduce manufacturing costs, resulting in significantly higher production rates. As part of their integrated system design approach, Cannondale extended its production capability to produce custom designs for customers that are fit to their individual needs, resulting in over 7000 custom-fit designs that can be produced using their vertical integration production strategy. Their highly advanced model allows the company to maintain a competitive advantage in all aspects of design, performance, and production.

What Lessons can be Learnt from these Pioneers?

  • Leverage customer input early in the design process
  • Use CAD, CAM, and rapid prototyping of models to obtain valuable feedback from all stakeholders, including end customers, manufacturers, and suppliers
  • Reduce design times by applying CAD early in the design process no matter how small, simple, or complex your design.

What is concept to product development?

Concept to product development is the process of transforming an initial idea or concept into a tangible, marketable product. It involves several stages, each of which contributes to refining and shaping the idea until it becomes a finished product ready for sale. Here’s an overview of the typical stages involved:
Idea Generation: This is the starting point where concepts are brainstormed, researched, or identified based on market needs, consumer preferences, technological advancements, or other sources of inspiration.
Concept Development: Once an idea is generated, it’s essential to flesh it out into a more detailed concept. This involves outlining the product’s features, benefits, target audience, and potential market positioning.
Market Research: Conducting market research is crucial to validate the concept and gather insights into consumer needs, preferences, and behaviors. This helps in refining the concept to better align with market demands.
Design and Engineering: In this stage, the concept starts taking shape through design and engineering efforts. Designers create visual representations of the product, while engineers work on the technical aspects, ensuring feasibility and functionality.
Prototyping: Prototyping involves creating early-stage versions of the product to test its design, functionality, and user experience. Prototypes can be physical (e.g., 3D printed models) or digital (e.g., software prototypes).
Testing and Iteration: Prototypes are tested extensively to identify any flaws, usability issues, or areas for improvement. Feedback from testing is used to refine the product through iterative design cycles.
Manufacturing and Production: Once the design is finalized and prototyping is complete, the product moves into the manufacturing phase. This involves setting up production processes, sourcing materials, and manufacturing units to produce the final product at scale.
Quality Assurance: Quality assurance processes ensure that the manufactured products meet specified standards and requirements. This involves rigorous testing and inspection to detect and rectify any defects or inconsistencies.
Marketing and Launch: As the product nears completion, marketing efforts ramp up to create awareness and generate interest among potential customers. A launch plan is executed to introduce the product to the market through various channels.
Sales and Distribution: The final stage involves selling the product to customers through established distribution channels. Sales teams work to promote the product, secure orders, and ensure its availability in retail stores or online platforms.

What are the steps in product development?

Product development typically involves several key steps, which can vary depending on the industry, product complexity, and company practices. Here’s a general outline:
Idea Generation: This is the initial phase where ideas for new products or improvements to existing products are brainstormed. Ideas can come from various sources such as customer feedback, market research, internal teams, or innovation workshops.
Idea Screening: Once ideas are generated, they need to be evaluated to determine their feasibility, alignment with business objectives, and potential market demand. Ideas that don’t meet the criteria are filtered out.
Concept Development and Testing: In this phase, the selected ideas are further developed into detailed product concepts. These concepts are then tested with potential customers to gather feedback and validate assumptions.
Business Analysis: This step involves a thorough analysis of the potential costs, revenues, and profitability of the product. Factors such as production costs, pricing strategy, market size, competition, and potential sales volume are considered.
Prototype Development: A prototype is a preliminary version of the product that is built to test its functionality, design, and feasibility. Prototypes can range from simple sketches to fully functional models, depending on the nature of the product.
Testing and Validation: Prototypes are tested rigorously to identify any flaws or issues that need to be addressed. This may involve internal testing as well as testing with real users in real-world conditions.
Design for Manufacturing (DFM): Once the prototype is finalized, the product design is optimized for manufacturing. This involves ensuring that the product can be produced efficiently, cost-effectively, and at scale.
Production and Launch: With the design finalized, the product moves into production. This may involve setting up manufacturing processes, sourcing materials, and establishing quality control measures. The product is then launched into the market through various channels such as retail stores, online platforms, or direct sales.
Marketing and Sales: Marketing efforts are ramped up to create awareness and generate demand for the new product. Sales teams are also trained to promote and sell the product to customers.
Post-Launch Evaluation: After the product is launched, its performance is continuously monitored and evaluated. Customer feedback, sales data, and market trends are analyzed to identify areas for improvement and future iterations of the product.

  • Reduces product development time.
  • Makes design flaws apparent.
  • Reduces product development costs.
  • Results in higher quality end products.
  • Offers a demonstration tool for obtaining user feedback.
  • Makes potential future system enhancements clear to engineers and inventors.

POP PROTOTYPE DISADVANTAGES

Disadvantages Of PoP Prototyping Include:

  • It may not include all of the features of a more complex complete system.
  • It cannot be used in place of rigorous system analysis.
  • It may not be representative of the full functionality of the end product.
  • Can lead to over-confidence in the solution.

PROOF-OF-PRINCIPLE PROTOTYPING METHODS AND PROCESSES

We find several ways to design your prototype. It is referred to as Rapid Prototyping, where the methods offer an initial fabrication of your design. The processes create prototypes which include Additive Processes. It’s the part used to build built-in subsequent layers, where the material is removed to make the final product called Injection Moulding. The thermoplastics are injected into harmful moulds and cast using urethane thermoset resins.

  • The additive processes build using plastic parts are layer by layer directly from a 3D CAD model. The 3D printers are developed for most additive processes and gained tremendous acclaim.
  • The Stereolithography (SLA) lasers cure thin layers of liquid UV-sensitive photopolymer. The SLA is cost-effective and used to produce intricate parts. It offers the best look and feels with the finished product. However, it tends to make parts that are relatively weak and have little UV stability due to the UV curing process.
  • Fused Deposition Modelling (FDM) works similar to SLA. It uses layers of extruded thermoplastic to create the part. The method offers complex, structurally sound roles and can use for limited mechanical and functional testing. The surface finish is poor compared to other methods as defined.
  • Selective Laser Sintering (SLS) is one method that creates the best part adhering to layers of polymer powder that cured using a laser. SLS prototypes are made with more complexity than parts made with SLA. Additionally, the details tend to have a rough texture and poor mechanical properties.
  • Direct Metal Laser Sintering (DMLS) mainly uses laser-generated heat that sinter thin layers of metal powders, including steel, cobalt-chromium, stainless steel, and titanium, to generate prototypes. DMLS parts offer highly realistic details and are less cost-effective than their plastic counterparts. It often leads designers to produce cheaper plastic and use prototypes that have the product fully machined.
  • The Polyjet uses a process that utilizes jetting heads and UV curing bulbs, which apply consecutive material layers in multiple colours and durometer in a single build. The method offers a representation of multi-material parts with excellent surface finish quality. The mechanical properties use the Polyjet process with ease.
  • Subtractive processes come with raw material and machine away with excess volume to produce a final part.
  • CNC Machining (CNC) is also one the most common example. It uses CNC machining, a part that can be produced from almost any variety of materials that include both plastics and metal. The advantages of CNC machined parts are highly accurate, made with the mechanical properties of the final product, and come with a highly polished and professional finish. Limitations include fewer complex geometries due to the tooling nature and significantly higher costs.
  • Injection Moulding is a popular prototyping process that cures thermoplastics into a mould from soft metal. The process is highly cost-effective and uses only one method representing the volume production fabrication. A wide range of resins is used with different properties and allow the parts to match up with the properties of the final product. The final cost per unit is typically different and is inexpensive, even after factoring in the cost of the mould. Still, the initial non-recurring engineering cost of the mould requires a significant up-front investment.
  • Casting is similar to injection moulding and uses a master model that fabricates using another method like SLA to create a silicone rubber mould. Liquid urethane thermoset resin is then used to generate the prototype. The urethane can be made to match any colour or texture. It uses highly cost-effective parts and has limited use in functional testing.

Whatever your proof-of-principle prototype requires, a suitable rapid prototype is used with a CAD model and material/finish selection. It is essential to consider the method, time to fabricate, cost of the prototype part, and the manufacturer, as the quality of a part varies rapidly between one fabricator and the next.

What is principle prototype?

The term “principle prototype” isn’t standard jargon in most fields, so it might refer to different concepts depending on the context. However, it could possibly refer to a prototype that embodies the fundamental principles or key features of a design or concept.

In product development or design, a “prototype” is typically an early version or model of a product used to test concepts, assumptions, and functionalities before finalizing the design. A “principle prototype” in this context could be the first iteration of a prototype that focuses on demonstrating the core principles or main functionalities of the product or system being developed.

For example, in software development, a principle prototype might be a basic version of a software application that showcases the essential features or algorithms without incorporating all the bells and whistles of the final product.

In engineering, a principle prototype might be a scaled-down version of a new technology or device that demonstrates the underlying principles of operation without necessarily achieving the full functionality or scale of the eventual product.

Without more context, it’s challenging to provide a precise definition, but in general, a “principle prototype” likely refers to an early prototype that emphasizes the foundational principles or key aspects of a concept or design.
