Some shapes print better than others. Avoid extremely thin parts, large overhangs (>45°), and floating pieces. Good print prompts: "a solid dragon figurine, compact pose, thick body, all parts connected, no floating elements". Adding "solid" and "compact" to prompts helps.
File → Import → glTF 2.0 → your GLB file. Check the model from all angles. Look for obvious problems: thin walls, disconnected parts, or holes in the surface.
Most slicers need STL format. In Blender: select your model → File → Export → STL (.stl). Leave settings at default. Your STL file is ready for the slicer.
Open PrusaSlicer (free) or Cura (free). Import your STL. PrusaSlicer automatically detects mesh errors and highlights them in red. Click the Fix button to auto-repair most issues. Cura shows errors in the Layers view.
In the slicer, use the Scale tool to set your actual desired dimensions. A figurine might be 80mm tall. A miniature game piece 30mm. A phone stand 120mm. Check all three dimensions are proportional — lock the ratio before scaling.
In PrusaSlicer: enable Support Material under Print Settings if your model has overhangs. For organic shapes like figures, use Organic Supports — they are easier to remove and leave a cleaner surface.
Choose your layer height (0.2mm standard, 0.1mm for detail), infill percentage (15–20% for display models, 50%+ for functional parts), and click Slice. Export to SD card or send directly to your printer.
Generate your first model in under 2 minutes — no design skills needed.
