As this technology continues to develop, it would be interesting to understand the expected print life of the cartridges for certain types of pastes. From the articles, it seems that the current strategy is to allow quick replacement of the heads (similar to an inkjet printhead cartridge), so I'm assuming that these cartridges are currently planned on being low-cost and disposible. (By the way, the peanut butter prototype was impressive).
William, both capacitive and conductive features can be 3D printed with this technology, mentioned on the company's website. We also give a link in the story for more info on the ink's characteristics. Transistors? Not quite yet.
Printing conductors is a worthwhile thing, but to gain much functionality there need to be other parts as well. Resistors and transistors would allow some functionality, but it seems that they would need to be placed, rather than printed.
Syringe extruders have been used in medical R&D for 3D printing various types of organ-like materials. But this is a new development in industrial uses. The combination of plastics and conductive viscous ink 3D printed in one pass is still in its early stages, but the open source technology means it can be developed faster via crowdsourcing.
A slew of announcements about new materials and design concepts for transportation have come out of several trade shows focusing on plastics, aircraft interiors, heavy trucks, and automotive engineering. A few more announcements have come independent of any trade shows, maybe just because it's spring.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
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.
