Build Your Own SLA/SLS

Hi Guys, I just wanted to share with you this Build Plate I just modified, since I did this my adhesion failures have been reduced to 0%

drilled 1.5mm holes in an 5-5mm array. Then I grinded the surface with a broken drill bit.

I've found that drilling holes into the build plate and hitting it with some 320 grit sandpaper (without scratching the surface this aggressively) is enough. Never had any adhesion issues.
