At the event, Mydesign, the Stratasys executives made a point of letting journalists know that the popular conception of 3D printing is inconsistent with the realities of using it in manufacturing settings. As you point out, there are a lot of applications that don't lend themselves to 3D printing.
I agree, naperlou. I think we're only scratching the surface here. Companies will learn how to combine information technology and 3D printing in all kinds of industries to produce customized products that no one has thought about yet.
"Injection molding has improved to the point that it is possible to make small production runs with molds that are cheaper. They may not be as long lasting as the traditional mold, but they are just fine for those smaller runs on an inexpensive machine."
Naperlou, you mean that 3D printing objects are of high quality and have better durability? I think in both cases the composition of material may be same and only the finishing may be better in 3D printing.
Charles, it's very nice to read this interesting article. I read many articles with respect to 3D printing and in one of them somebody specified that it can print ornaments, medicines etc. I think it peoples are aware only about merits and they presumes that it will be able to print everything.
Chuck, 3D printing is another good tool for manufacturing parts. In the past, CNC machining allowed cost effective production of small runs of parts. This is still true. Injection molding has improved to the point that it is possible to make small production runs with molds that are cheaper. They may not be as long lasting as the traditional mold, but they are just fine for those smaller runs on an inexpensive machine. Often the molds are made on a CNC machine. 3D is another low production rate technique that can be used in various situations. In "low" volume industries like aviation, this technique is very useful. In a mass customization environment 3D can really shine. I wonder when we will see personalization of prodcuts like automobiles with the addition of 3D printed interior parts (like special cup holders). Information technology coupled with 3D printing could make that a reality.
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.
