How do you load PC filament into the UM3?

Recommended Posts

There's probably a way to create new materials on the um3 but I don't know how to do it yet. so instead pick the closest material - probably CPE/UPET. You want something within 25C of nozzle 260C bed 80C. So ABS would work also. Then do:

SYSTE->build plate->set temp and set the buildplate to 80C. Go away for 10 minutes and come back when build plate is at temperature. You really can't do the next step until build plate is at temperature I beleive. Putting a cloth or towel or rag on the glass will speed up this step.

Now do PRINT and start your print. Wait for all the motors to stop moving around and go into the TUNE menu and adjust the build plate temp to be 80 (-20C from ABS?).

Now maybe exit and re-enter the menu and if the build plate is within about 3C of goal temp it should start heating the nozzles. Go to the nozzle with PC max and make sure the goal temperature is not 0C. Once it is the ABS (or other) goal temperature, do the same adjustment. Once you do all this exit the TUNE menu and it should just work.

This *will* get easier in the furture when someome explains the "right" way to add materials to your printer.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
