What are the top tips for hollow resin print 3D models?

For hollow resin 3D prints, the top tips are adding sufficient drainage holes, keeping uniform wall thickness (1–2mm), and using strategic supports to avoid issues like uncured resin or cracking. - Drainage holes: Place 2–3 on different sides to let excess resin escape—critical for avoiding messy residues or curing problems. - Uniform walls: Even thickness prevents weak points that break easily; 1–2mm works for most models. - Supports: Hollow parts are fragile, so supports are key for overhangs to maintain structure during printing. New users should start with small models (like miniatures) to practice hole placement and master these basics.
