DRAFT PLA 3D PRINT FOR TEST FITTING BEFORE CNC MACHINING OR METAL CASTING
An antique car enthusiast came to us to 3D print a rough resolution (draft version) PLA 3D print to test the fit of a part his buddy designed for him.
Since dimensional accuracy was critical, a calibration cube was also printed to verify dimensional accuracy & control for shrinkage.
Here was the FDM PLA 3D printed parts all finished!
The draft version PLA parts were almost a carbon copy of the original.
As expected, even though the parts were low resolution (cost-effective), they didn’t sacrifice any dimensional accuracy & fit like a glove.
A more cosmetic resin version was printed for showing clients at tradeshows.
As you can see, with a little sanding, the resin parts had the smoothness of injection molded parts.
