Layer height : 0.1mm -0.15mm. 0.2mm layer height are not suggested.
Platform adhesion type :To avoid warping, please add “Raft” as platform adhesion type, and then set the airgap 0.1~0.15mm, layers at least 4 and extra margin at least 3mm.Attached a picture below.
Printing temperature: 400-420 degrees.
Bed temperature: 100-150 degrees.
Fill density: 50%-90%.
Preparations and skills:
Close the cooling fan during printing（This is important,otherwise PEEK don’t crystallization well)
If print small part, suggest set the cooling fan speed at 50%.
Take down the printed fan parts before printing PEEK filament.
Suggest use PEI board or Carbon fiber board on working plate. If use Carbon Fiber board, please paint enough solid glue on it and dry it a little bit before printing.
Once PEEK filament package opened, avoid light and dry filament.
Tighten up the spring nut in filament feeder to make sure the PEEK filament silk successfully. Do filament extrude. firstly to see whether filament can be extrude fluently. And then focus on the first layer which needs to be flat enough.
PEEK filament is easily loose from rack because of its hardness during printing, so we suggest bundle it with something loosely.
When you finish the print, please silk the PEEK filament remnants out completely to avoid carbonization and blockage inside nozzle.
Before each printing PEEK, you should heat nozzle more than 400°C, and clean the PEEK pieces. (do same like the photo). Make sure PEEK extrude well before printing.
