eBay providing this service illustrates how mainstream 3D printing will become, at lest in terms of reaching consumers. It will be interesting to see if they expand the offering beyond customizing a pool of preset designs (which is obviously limiting on the design side) to provide more generalized services for 3D printing. Excellent report.
In product marketing terms there are three product categories. Mass produced, mass customized and full custom. Mass customization has traditionally been applied to larger items, such as automobiles. 3D printing seems to be able to allow this to be extended to very inexpensive products. This is really a game changer. It will also promote more local manufacturing. That could be interesting as well.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
