Pa6-cf vs pla+ dimensional accuracy (self.general)

submitted 1 month ago by YeyoGrapes to c/general

7 comments fedilink hide all child comments

Every thing i print in pla+ has been pretty dimensionally accurate on my K1c. However when i print the same thing in pa6-cf. (all fillament sunlu) the dimensions end up slightly smaller and the tolerances are arguably too tight. Magazines dont slide in and out easily, mag catch barely fits and wont slide. Pin holes are too small. Etc.

How would i address this. As it seems filament dependent not printer issue

I printed some dimensional blocks and got the exact opposite results i was expecting. The pla+ block came out slightly smaller than the set dimensions and the pa6-cf block was actually slightly larger than the set dimensions.

How do i address this. I guess it could make some sense as its the openings in the prints that are too small so the pa6-cf test print being larger could mean that the negative space is being taken up by this but if i scale the print larger to increase the hole sizes then the rest of the print will be too big.

Which slicer are you using? Have you calibrated your flow rate? You might be getting some over-extrusion, which combined with 100% infill can lead to dimensional inaccuracy.
