Those contacts look like some kind of pixelated video game.
Do they normalize to make the contact area the same regardless of whether the shape is round or square? e.g. If you pick 0.3mm diameter touchpoints, a circle would be 0.07mm in area, which means the rectangle should be around 0.2mm x 0.35mm. If not, they ought to.
Apparently for CW40 the squared tips are intended to be temporary. I wonder if they’re temporary here, too? I’d love to get some more info from Formlabs on the rationale behind the rectangular touchpoints and advantages/disadvantages they saw during testing.
