Ram extruders and control units

NETTO PRICE 250 € 

Can be used with our Clay 3D printers, or as a part of Add-on. Equipped with the strong geared stepper motor for precise volumetric dispensing of slightly diluted clay, porcelain, highly viscous liquids and pastes. Estimated working pressure up to 10bar. Easy to assemble, disassemble, clean and maintain. Does not use compressed air. Does not have exposed moving parts. Safe and silent solution.

• Capacity 0.5l (900g of clay).
• Internal diameter of clay container 45.2mm, length 380mm
• Dimensions D = 80mm, L = 930mm
• geared stepper motor Nema17, 1.68A per phase, 3Nm, 2-phase, 1.8deg
• Supplied with 1m long PTFE hose 16x14mm.

The pump is made of PVC. If used with the materials other than wet clay/porcelain, please check chemical compatibility first.

This is a spare part! While the ram extruder can be directly connected to the motherboard of your 3D printer as a second extruder, we recommend to use this as a part of 3D Printing KIT and connect to the printer via Control Unit. When used without control unit, this may need to change settings of your stepper motor driver. The stepper motor driver must support the current 1.7A per phase. In case of questions please contact us.
