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

Calibration should have been the first step before printing anything. Every printer needs to be calibrated. Every filament needs to be calibrated.

20mm cube is too small plus 100mm makes it much easier. If it comes out to 99.88mm then shrinkage is 99.88 in orca.

Pa6 should be measured after annealing and moisture conditioning. Annealing can cause it to shrink but moisture can cause it to expand.
