Raspberry Pi 3D Printer Demonstration

at 2:14 am. Filed under Complex Hacks, DIY Hacks, Electronic Hacks

 

Jon Wise demonstrates his Raspberry Pi 3D Printer, he is using a pen in the demo but it can use an extrude to print items. The mechanical movements leek very complex when compared to a standard XY table that is controlled using 2 stepper motors. The Pi has enough number crunching ability to get the job done though. I can’t wait to see this printing a complex shape, the movements are interesting to watch, it reminds me of the robot hands that use angular joints to move around.

    You probably don’t need Raspberry Pi brains for this – there are Arduino firmwares that control Delta-configuration 3D printers, and that’s one set of trig calculations more than this mechanism which has simple linear Z axis.

    It is a delight to watch but I would question the practicality: unless you’re 3D printing art pieces exclusively, many if not most of your models would have faces parallel to the major axis and using a cartesian printer would make for a better surface quality because your straight lines will be exactly that and not approximations of arcs.
