Few weeks ago I was comparing resin vs PLA 3D printed bolts and screw nuts. Since I don't have SLA 3D printer, I ordered those resin bolts. I thought that orientation of printing doesn't affect strength, but in discussion with company, they told me that probably there is a small difference. Then it is time to test this. I ordered 3 test probes, they cost me 20 USD.
