The Prusa Pro HT90 supports two print head configurations. The default high flow print head handles materials up to 300°C. For industrial materials like PEI, PEKK, and PEEK, use the high temperature print head, which reaches up to 500°C.

Removing print head

  1. Unload filament and cool the nozzle below 50°C.
  2. Turn off the printer and unplug it from power.
  3. Using a flat-head screwdriver, turn the stoppers by 120° counter-clockwise and remove them. Open the door to the maximum height.
  4. At the top of the printer, behind the HEPA filter, there is a connector assembly held by a thumb screw. Undo the screw.
  5.  Pull the entire connector assembly downwards to disconnect it.
  6. Open the C-clamp holding the air hose and cable bundle.
  7. Hold the print head with one hand and carefully disconnect the arms from the ball joints with your other hand, one by one. This will release the print head.
  8. Remove the PTFE tube collet retainer clip.
  9. Push down the collet, while pulling the PTFE tube out, to remove it.

 

Installing print head

  1. Lubricate the ball joints on the new print head with a small amount of PTFE lubricant.
  2. Connect the arms to the ball joints.
  3. Rejoin the C-clamp holder around the air tube and cable bundle.
  4. Insert the PTFE tube into the print head and secure the collet with the retainer clip.
  5. Reconnect the air hose and cable bundle behind the HEPA filter.
  6. Secure the connector assembly with the thumb screw.
  7. Close the cover and reinstall the cover stoppers.
