CNC, 3D Printer, Robotics and Programming projects. Rostock Base. Drew's Rostock: the print head. For my printer's hot end I chose a Mini J-head Mk II, custom-made by hotends.com.
The standard J-head is designed for 3mm filament. I liked the simplicity and light weight of the J-head, but my printer is intended to use 1.75mm filament, so I custom-ordered a mini J-head instead. I had been considering an Arcol.hu hot end at first - liked the idea of an all-steel extruder - or possibly a Budaschnozzle, but the Rostock design really calls for a head that's as lightweigt as practical to make full use of the platform. I won't be able to print the more challenging materials like teflon with this nozzle, but that's not really my aim anyway. Billy D's Rostock 3D Printer. Rostock - Car Boot RepRap.
