Halsey Manufacturing is on the front lines of the 3D Printing revolution in the manufacturing & prototype industry. We have 2 Rostock Max 3D Printers in our shop for small prototype projects made from plastics.
Printed Parts Plastic parts: Printed from PLA.
Thingiverse: Rostock (delta robot 3D printer)
Frame Top and bottom frame: Laser Cut Acrylic
Side and Back frame: Laser Cut Acrylic
Fasteners: Stainless steel, mostly M3 (some M4 and M8).
Linear Motion Timing belt: 3x 1524 mm GT2 belt (2 mm pitch, 6 mm width). Closed loops or open end is okay.
Timing belt pulleys: 3x GT2 plastic pulleys with 40 teeth. Smaller would probably work better.
Smooth rod: 6x 762x8 mm precision smooth rod. Drill rod is probably okay too, but some report that the bearings wear grooves into the surface as drill rod is not as hard as smooth rod.
Linear bearings: 6x LM8UU
Cable ties: secure linear bearings and timing belts to printed parts.
The length of belts and rods can be changed in the firmware.
Ball bearings: 3x 608ZZ, 3x F608ZZ. If you can't find F608ZZ, use 608ZZ with printed plastic flange.(Additional bearings needed for Airtripper's bowden extruder).
If using smaller pulleys, replace 608 (8x22x7 mm) with 688 (8x16x6 mm) or similar.
Extruder Filament drive: Airtripper's direct drive bowden extruder.
Hot End Hotend: MakerGear hotend for 1.75 mm filament, 0.5 mm nozzle.
Electronics Stepper motors: 4x NEMA 17 (3 positioning, 1 extruder).
Endstops: 3x ZM micro switch (pin plunger, no lever). You need only 3 top endstops. The original design also had 3 bottom endstops but they are no longer needed.
Electronics: RAMPS 1.4 or any other RepRap board.
Power Supply: 12v 30A
Firmware: Modified Marlin (see #Links). This is a pretty hacky proof of concept. Hopefully we will have better firmware soon.
Software: Same as other RepRap printers, e.g. OpenSCAD, Slic3r (see GitHub for recommended settings), Printrun.
