News and thoughts about 3d printing technology

Printer Matchup

The 3D printing world has seen many innovations in the past few weeks, highlighting the range of applications. Probably the most publicized piece of news is the successful flights of an unmanned aerial vehicle, or UAV, that can be 3D printed for snap fit assembly. It reaches speeds over 100mph and is nearly silent. Not only does this signal to the amazing possibilities to the commercial aircraft industry, but military and rescue teams could easily survey an area by creating one on demand instead of waiting for supplies. Or what if a rover on another planet could print one out to map the area?

This too will soon be possible as a new company called Made in Space has successfully tested a number of printers in near zero gravity. Most likely it will be used by astronauts and the International Space Station to print out tools and replacement parts instead of waiting for the mail to come.

What I find interesting about this zero gravity test is the type of printer that they used. A partner in this project is 3D Systems, an industry giant that produces various printers and services. The BFB 3000 is their entry level machine and the one they decided to highlight of several printers on this flight. I believe they created a wrench out of plastic (no moving parts this time). The success of their most basic machine gives only a small idea of what a more powerful printer could produce. It’s easy to print a basic part of that little machine but what about more complex geometries. Portability is not everything, especially since zero gravity means everything weighs nothing.

Here on earth there are more than a handful of machines that can  put the BFB 3000 to shame in areas like build time, materials supported, product rigidity, printer resolution, and so on. They only catch is they weigh probably ten times as much and cost up to twenty times as much.

My goal this week is to have a 3D print off. I will be gathering information from the websites of printer producers as well as private services to compare abilities and limitations of some machines out there. Categorizing them by size will make for fair fights and pricing is generally a function of this. I will do my best to get accurate prices but most companies do no list prices on their public websites.

Up next… the lightweights! Stay tuned.
