I want to use the Ultimaker 3- 3D printer to Print with Very high temperature materials such as: PEEK, PEKK, ULTEM and their carbon and glass fibre variants with print temperatures between 350 Degrees Celsius and over 400 Degrees Celsius.
The problem is the temperature malfunction that occurs just over 350 Degrees C, this is the part I need help with, How Can this Be bypassed?
the project information:
If you choose to do this, I am not responsible for the device jamming from excess paint/incorrect positioning of components during application of C-Coat (TM) given my directions.
The Experimental means by which the existing hotend(s) should to be modified in order to prevent the plastic contacted surfaces from bending or melting During Use is described:
---before doing what is described, please clean all oil and dust from the metal surfaces to be painted!---
The entire heating block (Excluding the Nozzle, and the axially adjacent Nut) is Coated with: C-COATTM ceramic thermal-insulation Paint, using a very small paint brush, then leave to dry.
raise the bottom of the heat-sink from the plastic holder so the heat-sink no longer makes contact with the plastic holder, either clamp the holder in this position or remove the top holder screw to release the tension in the spring all together, coat the bottom of the heat-sink with the C-Coat paint, then set aside to dry.
Now the top screw must be removed in order to release tension on the spring for this step- pull the heatsink assembly all the way back in order to expose the bottom part of the heat sink connector which comes into contact with the plastic holder, now clamp or zip-tie the heatsink assembly in this position and apply a thin layer of C-Coat to the exposed metal surface, leave to dry, then remove to clamp or ziptye and push the coated bottom of the heat sink against the plastic holder face, secure and paint another thin layer on the end of the exposed metal surface, leave to dry, at this paint all of the faces that directly contact the surface of the plastic holder have been coated with the micro insulation paint (C-Coat).
