Even if you don't get any scrap, if you printed a part and wanted to make a change to it...you could melt it down and reuse that to reprint it I would hope anyways. I am just talking about like plastic prototype stuff.
That was just the main advantage I saw with 3D printing...making prototypes before you actually machine the real deal. So instead of wasting material(machining) you could print it and recycle it if there were changes to be made.
Ann, one last thing on this subject. This might be obvious to some, but I just thought of it. I know the 3D printers are good for prototyping the part and assuring it's correct. What I was wondering was...and if this would work...can you take the model(file) for the 3D printed part and feed it to a cad/cam system so that there are no programming errors, so that it is an exact replica of the prototype? So no programmer error.
Cadman-LT, when we're talking about 3D printing a building, it's not usually made of plastic, but of more typical construction materials that begin as powders and are bound together to make a solid like concrete, brick, etc. So there's no melting down involved. For a variety of these materials, see an article I wrote for a UBM sister publication, Future Cities: Your Next City Block, Printable on Site: http://www.ubmfuturecities.com/author.asp?section_id=262&doc_id=523906
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
