Follow these design best practices to ensure your parts are printable and meet quality expectations:

Wall Thickness

• Minimum: 1.0mm for FDM, 0.4mm for SLA
• Recommended: 2.0mm+ for structural strength
• Avoid extremely thin walls that may warp or break

Overhangs & Bridges

• Keep overhangs under 45° when possible
• Angles steeper than 45° require support material
• Supports leave marks that may require post-processing

Small Features & Details

• Minimum feature size: 0.5mm for FDM, 0.2mm for SLA
• Text should be embossed or engraved at least 1mm deep
• Avoid tiny protruding details that may break off

Tolerances & Fit

• Add 0.2-0.4mm clearance for FDM parts that need to fit together
• Add 0.1-0.2mm clearance for SLA parts
• Account for material shrinkage in precision assemblies

Holes & Threads

• Design holes 0.2mm smaller for press-fit inserts
• Avoid printing threads — tap after printing or use threaded inserts
