Out of curiosity, what is the resolution of the 3D printer that fabricated the parts?
This is all the technical data we have regarding the printing of the alumide parts:
General material properties
Average grain size ISO 13320-1
Laser diffraction 60 μm 2.36 mil
Bulk density EN ISO 61 0.67 g/cmÂ³
Density of laser-sintered part EOS-method 1.36 g/cmÂ³ 85 lb/ftÂ³
I hope that answers your question :)
