I modeled an object in Blender intending to print it, but when I import it into PrusaSlicer or Cura, the dimensions don’t quite match.
In Blender, the dimensions are 178mm x 142mm, but when I import it into Cura or PrusaSlicer, it imports it as 180 x 138mm. I can manually adjust the dimensions, but why is this happening? And will it mess up my fit in the end? Who do I trust here? I don’t want to waste hours printing for nothing.
Could it be they’re both right? I mean, it’s possible that if you start rotating the model a few degrees on the z-axis, the measured dimensions on the platform might change.
Or, if it’s not a resin printer, you could always try the quick & dirty way: slice & start the print, pause it right after it extrudes the outline of the first layer (before it starts filling it in), and then measure the tolerances; resume if accurate, cancel if it’s off.
