@gsmith120: My sentiments exactly when it comes to the 3D printed perscriptions. Not that it can't be done safely, but there is far more to the practice than cool engineering to ensure safety and that someone doesn't take advantage of the technology for malevolent purposes. This past weekend is a harsh reminder of what can happen.
The furniture design is way cool. Not only does it illustrate what can be done with the 3D printing technology, but it also shows ingenuity in how this artist/engineer retrofit old equipment to meet his 3D printing needs.
I would't be too concerned at this point about the possibility of home drug synthesis. The current cool uses of 3D create new forms, but don't generate chemically different entities from the starting material. Even Dr. Cronin describes this concept as in the "science fiction stage." This is like worrying about what kind of seat belts to use in a faster-than-light spaceship! :)
I missed the mention of $1,000 a pop in the article. What is priced at $1,000 and is thus a "feel good product like EVs"? It can't be the chairs themselves because $1,000 for a stylish, ergonomic and comfortable chair is a bargain. Add in the possibility mentioned of customizing it to an individual customer and the value skyrockets.
Utilizing a robot to apply the layer-by-layer build-up takes 3D printing to another level by removing it from the limitations of a fixed sized enclosure. As a prototype process, the ability to iterate in full size to dial in comfort without shaving blue foam, shaping plywood or laying out resin is an incredible step forward.
The home medicine aspect of the article was interesting, but could have been a separate article as it addresses a totally different application and industry and raises ethical and legality concerns separate from the cool possibilities opened up by Kooij's creation.
A one-off might be steep at $1,000 but if you use it for a mold to make endless duplicates, that's pretty cheap. Some engineering could go into it to make it structurally sound while using less material.
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.
