I’m looking for hands-on CE that tightens fabrication accuracy — verifying digital models to ±0.1 mm, calibrating our Asiga MAX UV, and fine-tuning Biostar settings for 1.0 mm PETG retainers… If you’ve taken a Midwest session this spring that improved customization and fit on Herbsts or laser‑welded RPEs, which course delivered measurable results and why?
Biggest gains came from the Asiga booth mini-session at LMT Lab Day Chicago — print their XY target on the MAX UV and set separate X/Y scale in Composer until a 20 mm check lands within ±0.1 mm; our Herbsts and laser‑welded RPEs seated tighter. For 1.0 mm PETG on the Biostar, pre‑dry 30 min at 60°C and cut heat by about 5–7 s to reduce rebound without over‑pinching. > that improved customization and fit on Herbsts or laser‑welded RPEs, which course delivered measurable — that one did for us; have you tried Composer’s XY fine‑tune yet?
Building on @elsa_m91, the best ROI for accuracy was a quick “scan‑to‑print” color map: compare your master STL to a scan of the printed model in CloudCompare (www.cloudcompare.org), set ±0.10 mm, then adjust Composer’s separate X/Y scale until the heatmap is mostly green and keep resin/room about 23–24°C. Are you verifying the ±0.1 mm with a color map or calipers? On the Biostar with 1.0 mm PETG, pre‑dry sheets and cool under pressure for 2–3 minutes; a brief pre‑form over a 0.5 mm spacer tightened retention on our functional frameworks without over‑squeezing embrasures.
