The problem is we are using an INTAMSYS fdm 3d printer which is printing PEEK specimens using 0.4 nozzle, but coming to 0.2mm nozzle its not even extruding the material.we are using parameters like 0.1mm layer height and 0.2mm line width.
Are there any technical issue? or software issue?
Hi Vijay,
In my experience with PEEK, it's really important to set the layer height to at least 60% of the nozzle width. In this case, I'd go for 0.14mm. It's also critical to get the Z offset correct. If you haven't found it yet, it's buried under 'Settings->More Settings" on the Funmat. Even worse, it resets when you level, and there's no way to change it on the fly. For PEI and PEEK, I tend to find the Z offset around 0.5mm, but that is going to depend a little on how tightly you squeeze the feeler when you do bed leveling. Several times, I have had to adjust the level on the fly during the first layer rather than restarting the print with a new Z offset. If you include a couple lines of skirt, you can use that time to evaluate your offset and leveling.
Also, PEEK will crystalize in the nozzle if you leave it sitting hot for too long. Check for clogs by manually extruding. You might need to clean that out or swap nozzles. Don't be afraid to turn the heat up, PEEK can take it.
Best of luck to you.
Layer thickness in the Slicer should be set smaller than then nozzle diameter.
That is 0,05 to 0.15 mm. I would start with 0.1 mm which will produce very high quality surfaces. regards
Joachim
