1. The document discusses various rapid prototyping facilities and methods available, including 3D printing machines that can produce models from plaster or fluid acrylic, as well as machines that produce models from plastic thread using Fused Deposition Modeling (FDM). 2. It outlines the process for developing prototypes, including creating engineering drawings, discussing plans with fabrication experts, and providing files to schedule the work. 3. Examples are given of different concept prototypes that were created and the insights they provided, such as revealing issues with assembly, dimensions, and design flaws before full production.

- 2. Rapid Prototyping Facilities 3 different kinds of machines: 1. A machine producing models in plaster (not for functional tests). This process is called ‘3D Printing’ or 3DP. 2. A machine producing models from fluid acrylic type of plastics. The process is SLA-like, make very small details in thin layers to 25 microns but is rather slow. 3. 2 machines producing models from a plastic thread. They are made from self-assembly kits and are very cheap. The process is called FDM (Fused Deposition Modeling) and is rather fast compared to the aforementioned processes. 2 Original material by Thomas J.

- 3. Manufacture and Fabrication Facilities 1. Produce and engineering drawings and 3d sketches of the parts 2. Print them out on paper and go to discuss with Jan Frank Pedersen at the earliest opportunity. 3. Provide Jan with the files/drawings he requests and arrange with him a schedule of work and your deadline. 3 Original material by Thomas J.
