3D resolution test on the Form2

Here are some high-res photos of the 3D SLA test from Thingiverse (https://www.thingiverse.com/thing:1219068).  These were printed on the Form Labs Form2 desktop SLA 3D printer.  The material is Tough V5.  The model on the left was printed with 0.1mm layers, and the one on the right with 0.05mm layers.  These models were printed directly on the bed of the printer in the orientation shown here (ie the wood tabletop is in the same position as the printer model base).
