Pick the right process
FDM is the budget workhorse for brackets, jigs, and form checks (0.8 mm minimum walls). SLA resin captures fine detail and smooth surfaces for visual models and precision fits (0.5 mm walls). SLS nylon needs no supports and prints strong, functional parts, including print-in-place assemblies with 0.3 mm clearance.
Post-processing options include support removal and washing as standard, with vapor smoothing, bead blasting, spray painting, and threaded insert installation available.
