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
- The MK1-450 is fed filament from the top, through low friction tubing (2mm ID, 4mm OD) seated into a 4mm pneumatic fitting.
- 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.
- Beneath this, the filament enters into a 2mm ID 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.
- At the nozzle, heat is transferred to the filament, whereupon it is forced out through the brass nozzle.
