Kossel 250 V-Slot

Kossel 250 V-Slot 3D Printer - DIY Kit [BETA]

Smoothie has arrived!!! Say goodbye to 8bit and hello to superior 32bit quality prints.

Nothing quite captures the imagination like a Delta style 3D printer in action. The UltiBots Kossel 250 V-Slot is a fun kit to assemble and print from. It has a 250mm heated bed with an aluminum heat spreader and Kapton Heater. This kit uses a PG35L geared motor directly mounted to the effector. Our Micro Extruder is compact, lightweight, and proven. It is unlike Bowden Tube style exctruders because the filament is fed directly into the E3D Hot End. Together with V-Slot extrusion and wheels this kit is straight forward and less complicated to build compared to many FFF 3D printers.

Current lead time is 1 - 2 weeks.

NOTE: Non-assembled Traxxas Ends, Carbon Rods, and hardware are included by default.

We recommend these other items:

• ABS or PLA Filament - something to print with
• NEMA Vibration Damper - for quieter printing (need 3)
• M4 Tap - needed for Traxxas arm assembly
• Ball Head Drivers - needed for motor mounting
• Metric drill bits set - needed for cleaning plastic parts
• Ratchet crimper - for clean wiring
• Basic tool kit - metric size tools
• PET tape - for ABS part adhesion on print surface
• 4oz dropper bottle - for storing "ABS Juice", recommended for ABS part adhesion

***NOTE: Not all companies publish Z height correctly. Z height varies from the Peak Z to the Perimeter Z. Be sure to research and compare TRUE Z heights. K250VS Perimeter Z heights are 190mm for Traxxas Arms and 180mm for MagBall Arms. Peak Z = max Z height when all carriages are in the home position. Perimeter Z = max Z height when the print nozzle is over the outer perimeter and one carriage is in the home position

NOTE: THIS KIT IS IN BETA STATUS PRIMARILY BECAUSE THE BUILD GUIDE IS NOT YET FINALIZED. THE DESIGN IS GENERALLY STATIC BUT MINOR TWEAKS ARE EXPECTED. PERSONAL SUPPORT DURING YOUR BUILD, LEVELING, AND CALIBRATION IS AVAILABLE.
