Build made to test XYZ, orientation, positioning,

Calibration tool and models

After using @JoshK’s calculator and 4-cube form file, and from reading various ideas on the topic here, plus noodling a bit myself, I created a new excel calculator to insure dimensional accuracy in all three axes, as well as a step-gauge and test cube. Dialing in your printer is really important if you’re prototyping injection molded parts that need to snap together, so that’s why I built this. I could get X & Y pretty good with Josh’s calculator, but my Z dimension was way off, and was causin…

Anyway, measuring 3D printed parts at the micrometric level is only going to lead to disappointment. Apart from the fact that the printer istelf can’t guarantee a .01mm precision let alone .0001, you have to remember that plastics have a huge coefficient of thermal expansion which makes micrometric measurement almost pointless except in very specific situations.

If you aim at maximum precision you’ll have to iterate. Take notes of the model orientation (you can’t copy model orientation from one part to another yet, but @Frew said they were working on it… no pressure though ) and cure settings and correct the model in your CAD software. You can use XY corrections on the printer and model scaling in PreForm but neither of those options are suitable for precise 3 axis precision over different prints.
