Printing replacement part for Mk4 - which profile is the strongest?
Hello all,
When I assembled my mk 4, I accidentally stripped a screw installing the Y belt tensioner, and when removing the part to fix it, cracked it a little. It's still functional and it prints pretty well, but one of the first things I want to print now is a replacement piece for it and reinstall it (more carefully).
I am guessing I want to use PETG, which is the strongest filament I have (I have ABS too, though - no ASA). I am going to do 100% infill, but - what print profile will give me the strongest part - .05 ultradetail or .3 draft?
Thanks!

100% infill is not recommended, if you want the item to be solid, use lots of top and bottom layers. so there is no room for infill
you can also Increase the number of perimeters too,
Stefan from CNC kitchen did loads of tests and came to the conclusion that, with a 0.4mm nozzle, 0.2mm layer height gave the strongest prints
print a little hotter than normal to get good inter layer bonding.
Note the standard settings work well for most folk
Have fun.

100% infill is almost always pointless. I printed several complete sets of parts for Mk4, Mk3S, and Mini with PETG or PCCF, with 3 perimeters, 15% cubic infill, 0.2 mm layer height, no issues.
Anyone who claims can see an appreciable difference between 0.1 mm and 0.05mm layer height, I call BS on.

Thank you for the tips on this. I have printed and replaced the Y belt tensioner with one I printed. Pretty happy with the quality of the print using Sunlu PETG.
