There are plenty of fancy 3D printers on the market. Not all of them meet open source standards though. The LulzBot Taz 6 3D printer has open source hardware, so you can make modifications and learn new things in the process. It is built with an open filament format, allowing you to print with PLA, HIPS, ABS, nylon, polycarbonate, and various other materials.
With tool head upgrades, you can do more with this 3D printer. You also get a camera to take a picture of your finished print or check the status while printing. With MatterControl Touch T10, the Taz6 serves as an internet-connected printer, meaning you can send models to your printer from anywhere. Do you own this printer? We would love to know your experiences with it, so share them here.
