If you've navigated through the endless sea of 3D printers at this weekend's Maker Faire, you may well have caught a glimpse of the Series 1 Pro, the latest offering from San Francisco-based Type A Machines. The printer, which is still in the "engineering concept" phase, trades its predecessor's wood frame for a more solid aluminum version. The WiFi-compatible device has a build volume of about 18 liters, according to the company, and will be available in the third quarter of this year. That's the printer up top, pictured alongside Mark II, a little robot printed on the original Series One. Down below, you'll find a short press release.
