Global Sources Group: There are very few companies dealing with rapid prototyping overseas. One of them is Global Sources Group. It can boast of offering overseas rapid manufacturing. Today’s fast world speaks of competition. The US is no exception. It has been ruling the world since the last century on this count. This has led to the emergence of Global Sources Group. The customer would always feel obliged by seeking the services of Global Sources Group, as this would result in substantial increase in his productivity and profit. This company is associated with factories across Vietnam and China. Thus, the required competitive edge that is needed in market of today is ensured.

Global Sources Group has the ability of designing the rapid prototype within 10 days. Not only that, the patent of the new product acquired can be obtained within 4 weeks. Here, time is equated with money. Hence, the new product would be air freighted to the topmost overseas factory to have the quality and fast productivity maintained. This would thus take the client to the subsequent level.

Global Sources Group assists companies in rapid prototyping, right from design to manufacture. It specializes in manufacturing and ‘Art to Part Design’. This company has been into rapid prototyping for the last 20 years.

Delcam: Another company dealing with rapid prototyping overseas is Delcam. This company was established in 1968, when 3D modelling was not even talked of. 2D drawing was prevalent. Then in late 1980s, rapid prototyping was born due to the efforts of Ford. The process can be described as follows: Rapid Prototyping can be made effective if a good quality STL FILE is used. It is independent of composition. STL file, having property of water tightness can be exported by Power SHAPE. The errors can be automatically detected and repaired by a set of ‘wizards’. It provides the customer with total control over the creation of mesh. The intuitive, fast model from PowerSHAPE carries out the repairing of tools. This means that if the surfaces of original model of CAD are damaged or missing, the work won’t be stopped, i.e. the customer can easily carry out the fixation of model and go on with his work.

CopyCAD, Delcam’s software for reverse engineering, possesses comprehensive tools to repair and modify the STL models on an interactive basis. This enables the process chain to continue in an unbroken manner even if there is no CAD model to start with. Power MILL, Delcam’s absolute machining solution has the capacity of producing accurate tool paths. They can be built upto five axis-simultaneous, directly from the STL models. This causes the manufacturing process to become more flexible.

Delcam’s software is being tried and examined with majority of general Rapid Prototyping Systems, to produce both, prototype tooling and form-and-fit testing parts. Its constant involvement in projects of Europe like HiperMoulding and CARP ensures that the customer is guaranteed of results of high quality irrespective of the type of Rapid Prototyping System used. Delcam has been into news in terms of rapid prototyping for quite some time now.

New product development and innovation is much more difficult and time consuming than most other business activities. Automotive rapid prototyping greatly enhances learning speed and reduces the risk of new automotive parts development.

Historically, the automotive industry has been using rapid prototyping as an important tool in the automotive parts design process. The extremely fast-paced automotive design cycles require an extremely fast prototyping system which can produce car parts fast and inexpensively.

The main objective of automotive prototyping is to learn quickly: how a new automotive product behaves in its natural working environment, before transferring the prototype to the production line. Many times, mistakes are learned only after a new automotive part is launched. This is the main explanation for poor automotive parts design, from product mismatch, poor engineering and function or finish, and overpriced production. In order to accelerate the learning curve, before these costly automotive prototyping mistakes are made, one must accelerate and facilitate feedback loops from tests in the lab and market trials.

Automotive Manufacturing Technologies

Working with an assortment of rapid prototyping equipment, automotive prototyping engineers utilize the most advanced 3D printers, in their quest for perfect form, function and utility. Working in advanced manufacturing centers, the automotive engineers use the technology to verify what they are doing, and, equally important, to save tremendous amounts of time, and money.

Automotive Rapid Prototyping Compresses Development Time

The advantages of 3D rapid prototyping model creation versus viewing a cad/cam model on a computer screen is palpable. Automotive parts engineers get together discuss the pros and cons of a rapidly produced automotive parts model and discuss the pros and cons of the design, as they pass it around, twisting and viewing the prototype, and decide if that is what they had in mind. This way, problems get solved up front, before going to the assembly line! Once determined that the automotive prototype design is a go, the model can then be sent to a die maker.

Automotive Prototyping and the Die Maker Process

The die maker cannot use model to make the die, but because they have it in their hand and can look at it and feel it, they can determine where the parting lines will be and exactly how much steel they will need to produce it. The timing of the die process is greatly compressed.

Examples of Automotive Rapid Prototyping Parts

· Engine castings and parts

· Car Engine parts

· Auto Mechanical parts

· Car Dashboards

· Car Handles and Knobs

· Auto Body Components

· Car Trim parts

Fail first Paradox in Automotive Rapid Prototyping

The automotive rapid prototyping paradox is to fail earlier rather than later. By failing earlier, the design engineers surprisingly succeed in accelerating the project; this greatly reduces development cost risk. By considering all automotive prototype failures as learning experiments, the engineer has much less stress, knowing that they are practicing the old adage, that success comes from ninety-nine percent failure and introspection.
