Australian Design and drafting Services 3D printing house to build in 20 hours! 5

3D printing house to build in 20 hours!

3D printing seems to be the latest “ultra-cool” movement in technology. Ever since I heard about 3D printing (I only knew about small 3D printers), I began to imagine how would the world look like if 3D printing will become such a common procedure like paper printing. A world full of home-made toys, utensils, dishes and God knows what else. But, what if, 3D printing could be that cool as to solve the issue of shelter across the world, what if there could be a feasible solution to 3D print houses?[/fusion_text][fusion_text]

Such was the idea of ContourCrafting, whose CEO had a very insightful TED talk this year (video below). Professor Behrokh Khoshnevis, from the University of Southern California, is the man behind this awesome concept. In plain English, he wants to build a 3D printer that would be able to build a house in less than one day, in 20 hours!

This huge 3D home builder will create the entire building, from the foundation, floor, walls, ceiling and even plumbing and more advanced stuff such as electrical wiring! At the beginning, I thought it could only build the main block of the building, but apparently this 3D printer from ContourCrafting is far more crafted than that! It would build the house in such a way that you’d only need to put the windows and the doors in the cutouts that have been left by the huge construction robot.

Maybe you wouldn’t like living in such a home built by a gigantic 3D printer but think about almost 1 billion people that literally don’t have stable shelter. Do you think they’ll think twice before moving in? This is the immediate and most urgent use for 3D printed home, but I can imagine that for the rest of us, or those that have money, being able to print your own house in less than one day would be really something.

Awe-inspiring 3D printers that will reshape the construction

Right, from the beginning I asked myself: how are they going to build big buildings, with hundreds of flats? How are they going to achieve that? The CountourCrafting guys have created the model of a 3D printer capable of building even that! And something that really surprised me was some sort of a 3D printer that was capable of climbing as soon as he finished printing a level!

It seems that this impressive technology is also capable of building more advanced buildings, with advanced designs. By using a perfectly calculated geometry and strong material, these house-building 3D printers can even replicate historic or very advanced buildings. How cool is that!

Sounds great on paper, but in reality…

Behrokh Khosnevis says that this technology will prove to be far more secure and safe than current construction methods are. He says that 10,000 workers die per year in the USA alone and 400,000 more get injured during construction. 3D construction printers would eliminate that and also decrease a lot the time needed to build a house. But there are a few drawbacks that we can’t ignore, especially not at this moment.

Imagine how many jobs would get lost if this technology were to become mainstream. I have always supported a civilization that’s relying on technology, thus being more automated than manually run, but right now, this kind of technology is simply impossible. I can see a few houses being built using this concept, but it will not gain mass appeal because the government needs to keep the population employed. But, then again, the same thing happened when the Industrial Revolution began.

People were afraid that they were going to lose their jobs because technological devices were there to take tasks from humans. But we look behind and we can clearly see that humanity found a place for everybody. So, this would be an issue for the moment, but I can imagine that by 2050 or so, 3D printed homes will not be just a “cool concept” but rather something ordinary. The appearance of the Web didn’t kill jobs, it changed the world; 3D printing won’t kill construction, it will reshape it.

A brave new world

This technology is so exciting that I want to be able to be a part of it, I want to see 3D printed houses around me and people living in them. I want to see huge 3D printers outside towns, building from the ground homes for everybody. And I get even more hotheaded when I start imagining that we could use this technology to build houses on other planets, starting with the Moon, for example! We live in exciting times.[/fusion_text][/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]

By increasing material manufacturing on Earth and other planets rapid build houses and tightening budgets is a very interesting point of view, more than one reason. In space, which will provide us with a lot of design flexibility for those unique, highly functional but can not simply be assembled with other methods of building to make way.

On our own planet, 3D printing houses will become more common, the United Nations predicts that the world's future will add almost 100,000 new homes a day within five years.

Compared to other houses, the cheap and fast to build housing units made to make by earthquakes, cyclones and floods and other natural disasters in the affected areas recover quickly. In case of emergency, cost, energy and material restrictions it is very large, so people need never unusual sources of inspiration.

We can say that no one can do better than potter wasps (wasp/hornets) better, it methodically countless layers of mud everywhere covering layers, eventually forming nest-like pottery. For its part, the industrious insects may be the world's smallest (and most environmentally-friendly) 3D printers.

Italian engineering company manufacturing a variety of sizes WASP 3D printers, recent plan to follow its name, build a shelter for human habitation. Last year, the company exhibited a 4.5-meter printer that can handle simple and highly flexible material, such as mud, clay or natural fibres. Now, the company is even higher to create 3D printers, 12 meters high in this 3D printer is called the Big Delta.

It consists of a 6 m diameter solid metal frame support, with simultaneous rotation of the nozzle mixer functions can be uniformly printed material, it is said to work just ten watts. It can use a variety of materials, from clay to clay, and can be reinforced with a small number of chemical additives on the structure. It is also possible to use cement, but this will contradict with the company's green initiatives.

The company said it through 3D printing houses to provide health assistance to the affected areas, such as on the walls of houses repellents.

Since 3D printing house in shape, size and material selection are very resilient, so its potential is far more than meet the needs of developing countries affected areas. In fact, WASP represents the southern coast of Sardinia Iglesias town have shown interest in the Big Delta, the recent use here has the first printer built out of housing units.

Big Delta will be exhibited in Rieti, Italy Lazio region, it will also become the focus of the stage.

How to Solve Engineering problems with Finite Element Analysis (FEA)

Engineering problems with Finite Element Analysis (FEA)

With finite element analysis or FEA services, you can easily find an apt solution for any complex engineering problem by subdividing your problem into small and manageable finite elements. FEA services involve the use of finite elements to successfully reduce the complex differential equations of a structure to a set of easily solvable linear equations.[/fusion_text][fusion_text]In short, finite element analysis can be described as an engineering technique that is used to predict the response of structures and materials to applied loads such as temperature, force, displacements and vibration. Before you develop a design, you can model it, evaluate its performance and address failure points with FEA services.

Reverse Engineering Using 3D Scanners to Generate CAD Models

Reverse Engineering Using 3D Scanners to Generate CAD Models

Today’s engineer lives and thrives in a 3D CAD model world. CAD models provide design versatility and a direct link to rapid prototype development. As a result, our libraries of CAD models are ever more important. Reverse engineering using 3D scan data is a fast and efficient way to generate CAD models when an object exhibits a complex shape or when a 3D model does not exist for a component. 3D scanning equipment captures the physical geometry of a component and transforms it into a 3D digital model.[/fusion_text][fusion_text]Reverse engineering can be used to:

  • Obtain CAD data that captures an object’s original design intent
  • Design a new part to fit a legacy part
  • Accurately model performance surfaces
  • Update CAD models of your tooling to match shop-floor changes
  • Redesign a part without manufacturing defects
  • Modernize your manufacturing process
  • For animation or visualization
  • To perform a dimensional and comparative analysis of an object
  • For performing FEA or CFD analysis
  • To digitally reconstruct a damaged part so that it can be reproduced in its originally intended form using rapid prototyping or CNC technologies

3D scanning technologies come in many shapes and forms. Some are stationary, requiring the part to be brought to the scanner. Scanning laser technology then surveys the 3D contour of the surface and saves the geometrical data to a CAD model. 3D scanners have been used to scan vehicles, aeroplanes, historic monuments, ships, submarines, buildings, monuments, sculptures, consumer products, to name a few.

An example of a complex 3D scanning problem is the 3D scan generation performed by Creaform using their HandyScan3D handheld unit in combination with a long-range scanner of the United States Marine Corps War Memorial replica, located at the Marine Corps Recruit Depot in South Carolina. The purpose of the project was historical preservation so that the memorial could be recreated in the future if it were ever to suffer damage. The handheld scanner used for this application is capable of scanning ½ million points per second with up to 30 sq.m resolution accuracy and 60 sq.m volumetric accuracies.

How do 3D scanners work?

Laser scanning passes a laser line over the surface of an object. Surface data is captured by a camera sensor mounted in the laser scanner which records and saves three-dimensional information to a model. Regions of an object are scanned at once, allowing hundreds or thousands of closely positioned points to be surveyed at once. Several types of laser scanners exist, including line, patch, and spherical. Laser scanning is performed without making contact with the object. Digitizing is a contact-based form of 3D scanning in which a point or ball probe is scanned over points on the surface of an object to record geometrical position information. Digitizing is more accurate for industrial reverse engineering applications when the precision of a complex part is desired, whereas 3D laser scanning is far more desirable for non-standard or organic shapes such as sculptures or a person’s face. Digitizing is often limited to smaller objects, while 3D laser scanning is more versatile, and can be used to scan large objects, such as vehicles or buildings. White light scanning, CT scanning and photo image-based systems are alternate methods that are being used 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 prior to scanning.
  • Some intricate objects, such as large sculptures, require the use of 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 difficult problems.

Inspection Using 3D Scanning Technologies

Inspection is another valuable use of 3D scanners, allowing parts to be rapidly checked to ensure that manufacturing tolerances have been met. 3D scanning technologies are commonly used in First Article Inspection, where high accuracy and extremely fine resolution are required in order to verify that a physical part has been produced according to production drawings. Scanners can also inspect a “final” part so that final part models and drawings can be generated for use as blueprints and for re-manufacturing a part. Inspection of aging components or systems is also possible using these technologies. Foraging ships or aircraft, for example, or when modifications are required to update the vehicle, a reverse engineer using laser-based 3d scanning technologies can produce the physical dimensions of the vehicle or its parts.

A prime example is reverse engineering an F-15 test plane for NASA engineers conducted by Direct Dimensions, Inc. (DDI) in 2006. The engineers at NASA desired to modify the test plane and obtain in-flight data to verify their design improvements. Due to the daunting costs associated with full-scale testing, and the danger associated with measuring pressure on a plane moving at supersonic speeds using a chase plane, they chose to reverse engineer the plane so that they could simulate the design changes using computational fluid dynamics (CFD) software prior to implementation and testing.

DDI used the FARO LS 3D laser system, a portable scanner designed for scanning the shape of large objects, capable of acquiring up to 120,000 points per second over ranges of up to 80 meters. This technology allowed DDI to quickly and accurately capture the exterior shape of the jet with an accuracy of +/-6 millimetres. The raw 3D scan data provided a high-resolution point cloud of laser-reflected spots off the plane’s surfaces that were digitally processed and converted to CAD format. Over 50 individual scan from different positions were used to generate over 50 million data points that were used in reverse-engineering the F-15.

Australian Design and drafting Services Importance of CAD Platforms in Designing Products 4

Importance of 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.

How CAD Modeling helping Water Distribution Systems

The use of 3D modelling over the past 20 years has greatly improved the ability of engineers to design, model, and fabricate complex parts for a variety of industries, including automotive, aerospace, and biomedical, just to name a few. Imagine a tool that would help civil engineers, city planners, and construction crews plan out networks for their water distribution and wastewater management operations with the click of a mouse. Such tools do exist and are readily available today to assist difficult optimizations. The network engineering design of pressurized pipelines is a highly complex one, requiring significant planning and understanding of regulations and the design criteria. As a result, it is a highly time-consuming task, requiring significant effort and prior knowledge. Even with prior understanding, it is cumbersome to meet all of the necessary design criteria (such as pipeline minimum slope, the spacing between valves, intersection with existing utilities, and pipe cover) and other applicable quality standards.[/fusion_text][fusion_text]

Design and Optimization Tools for Better Water Infrastructure

Let us consider that you need to design your own water network with a bottom-up approach using the available water source, information on the constituent, age, and tank-mixing in your design. In such a scenario, the common questions could be:

  • How would your water system handle a fire?
  • Would there be enough water at each fire hydrant?
  • What are the design limitations in your water network?
  • What happens if there is an excess flow from a particular location?
  • Is there a sufficient flow of water to handle your system needs?

CAD programs, with the use of 3D modelling to design complex water distribution systems, can provide the answer to the above questions. For example, Bentley System’s WaterGEMS, which runs as a stand-alone tool or in conjunction with MicroStation, AutoCAD, or ArcGIS, is one of these tools. Innovyze’s InfoWater and PipePlan tools provide a similar solution. These tools are being readily adopted by utility companies, townships, municipalities, and design engineers to provide efficient design and optimization tools for water infrastructure and networks.

A few of the benefits of using CAD for developing water distribution networks are:

  • The ability to visualize the network in a 3D environment
  • The ability to model pipe pressures
  • GPS tagging of the pipe network and existing pipes/utilities that allows designers to determine points of interference and avoid critical problem areas
  • Ability to model-flow rate, pressures, and loss through nodes
  • Design for high-flow conditions such as first responders at a fire requiring the use of fire hydrants

Real-Time Examples of CAD Use in Water Distribution Networks

Such CAD tools are already widely used and are most likely to be the future of civil engineering planning and design. Salt Lake City in Utah and Huntington Beach in California are some of the two cities that have already adopted WaterGEMS software for designing, optimizing, and maintaining their water distribution networks. Salt Lake City’s water distribution network serves almost half a million residents and includes over 1,000 miles of pipes. It has a complete geographical information system (GIS) for its water, sewer, and stormwater infrastructure, which has been built into its model. Using WaterGEMS, the city is currently building a hydraulic model for its water distribution system using existing data that can be updated and maintained as the city expands.

The tool has been used to determine the optimal pipes for replacing pipes where customers have complained that the flow was insufficient during peak periods. Using this guidance, the city was able to remediate the complaints. Further, the city was able to meet the fire department’s flow requirement of 1500 gallons per minute for all fire hydrants with high pressure.

Best Known CAD Tools for Optimization and Piping Plans

  1. WaterGEMS: WaterGEMS is a tool for engineering design, analysis, and optimization of water distribution systems. Features of WaterGEMS include steady-state and extended-period simulations, constituent-concentration analysis, source tracing, as well as tank-mixing, water-age, and fire-flow analyses. Controls can be rule-based or logical, and pumps can be single or variable speed. These tools help users find operational bottlenecks, minimize energy consumption, and model real-time operations. Criticality Analysis is another important feature that allows users to find the weak links and valves in the water distribution system. The tool offers the ability to import CAD, GIS, and database data or perform the polyline-to-pipe conversion from DXF files. The program also provides optimization tools to facilitate and enhance design iterations. What is perhaps more impressive is that the program can link directly to Supervisory, Control, and Data Acquisition (SCADA) systems, namely SCADAConnect, a software tool that provides an environment for monitoring and controlling the network in real-time. Using this tool, the pipe network model can be monitored in real-time, allowing a comparison of the model with the operation. Problems and deficiencies can be investigated and evaluated using forensic performance analysis.
  2. PipePlan: A second tool that offers similar utility is Innovyze’s PipePlan software, which provides a geospatial environment for water network analysis and design for detailed hydraulic network models. Design engineers can produce and validate distribution and transmission line designs iteratively with very little effort. PipePlan allows for both horizontal and vertical alignments and helps define the location of pipe fittings such as bends, air valves, washouts, end caps and tees. An important feature of the tool is its interference checking, i.e. the ability to automatically report intersection with existing/proposed utility networks.

Conclusions

Maintaining water distribution networks is going to be a challenging task for governments across the globe. In this context, CAD will play a significant role in enabling the proper regulation of water flow as cities and urban areas continue to expand. Therefore, tools such as WaterGems and PipePlan will have an even more critical role to play in providing efficient design and optimization of water networks in the future.

Australian Design and drafting Services CAD importance in Product Development

CAD importance 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?

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?

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.

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.

Raster to Vector Conversion

Wondering why you need to do away with your raster images and move towards vector images? Read on to find out more about raster to vector conversion.

If you are from the manufacturing or mechanical engineering industry, you will be in constant need of complex, yet accurate drawings. Though raster images were popular in the past, they are resolution-dependent and do not yield very accurate results. If you have been still using raster images, it is time to move towards vector images, as a vector image can yield more accurate drawings and images.

With raster to vector conversion, you can quickly and effortlessly convert uneditable paper drawings into accurate vector files that can be edited in the CAD software of your choice. The converted files can be saved in any vector format (WMF, EMF, EPS DXF, or AI). Once your file is converted into a vector, it can be effortlessly read by any CAD program like AutoCAD, Corel Draw, Adobe Illustrator, Microstation, VectorWorks, TrueCAD or FastCAD. In fact, raster to vector conversion is a direct replacement for traditional tracing and digitizing which could be less accurate and more time-consuming.

Why use vector images in CAD programs?

CAD programs can import and display raster files, but you will only be able to look at the file or trace it. You will be unable to change or edit it. This happens because CAD programs can only work with vector files. If you wish to edit a raster file in your CAD program, you will first need to convert it into a vector file through raster to vector conversion. Once the file is converted into a vector file, you will be able to import it into a CAD program and edit it easily like any other drawing you have created in your CAD program.

How is a file converted from raster to vector?

  • A paper drawing is scanned by using a scanner and a raster file is created
  • The file is converted from raster to vector through raster to vector conversion
  • The vector file is imported into the CAD program
  • You can easily edit your vector drawing in your CAD program

Who requires raster to vector conversion?

  • CAD professionals who need to need to quickly scan, convert and edit drawings in popular CAD programs
  • Mechanical, electrical and architectural engineers who require their drawings done by hand to be edited in CAD software
  • Professionals who need to convert small faxed drawings into vector drawings
  • Technical professional who have several drawings in the bitmap format and need to convert this data into an editable vector format
  • Photo editing professionals who need to convert photos/artwork into vector files for easy engraving or cutting
