Straighter Teeth and Sintered Violins: Videos Show 3-D Printing Developments

We’ve been checking out a lot of videos this week to get our heads around 3-D printing and the state of the art. Here are a few that made us think.

This one is a good primer on 3-D printing and is also a call for entries in the 3-D for Development (3d4D) Challenge, a competition that encourages innovation to help deliver social benefits and relieve poverty in the developing world. “The Challenge aims to find transformational uses for additive technology that deliver real social benefit in the developing world,” say the members of techfortrade, the UK-based charity that is sponsoring the competition.

How to get noticed if you’re looking for a job in the additive manufacturing industry:

This next one is interesting for two reasons. First, you can see the amazing artwork of architect and designer Neri Oxman, a professor at MIT’s Media Lab. Second, Oxman’s pieces highlight an Objet multimaterial printer. Experts in the field see the ability to seamlessly print an object comprised of more than one material as the next evolutionary step for 3-D printing technology.

Check out this report by the BBC on a working bicycle laser sintered from nylon powder. Or this laser-sintered violin:

Finally, did you know that Invisalign invisible braces are made using 3-D printers? Neither did we. They use production printers from 3D Systems.
