MK1-450

The MK1-450 is our high temperature print head, and works with 1.75mm filaments which print at temperatures between 250°C and 450°C.

This includes the following materials:

• PC (PolyCarbnoate)
• PEEK (PolyEther Ether Ketone)
• Ultem

Description

1. The MK1-450 is fed filament from the top, through low friction tubing (2mm ID, 4mm OD) seated into a 4mm pneumatic fitting.
2. A cover plate maintains pressure, via a spring, against a rod with two bearings; these bearings keep the filament pressed against and centered on the gibbed (toothed) portion of the drive shaft of the stepping motor.
3. Beneath this, the filament enters into a 2mm OD PTFE guide tube, which leads the filament to a stainless steel delivery tube (due to temperatures too high for the PTFE) and thence to the brass nozzle. The stainless steel heats up to some extent, allowing for pre-heating of the filament.
4. At the nozzle, heat is transferred to the filament, whereupon it is forced out through the brass nozzle.
