Design Right, Print Right
Great 3D prints start with great designs. Whether you're using Fusion 360, SolidWorks, or Gemvision Matrix, these fundamental principles will help you create models optimized for 3D printing.
Wall Thickness
Minimum wall thickness depends on your printing technology. For FDM, aim for at least 1.2mm (3 perimeters with a 0.4mm nozzle). For resin, you can go as thin as 0.5mm for small features.
Overhangs and Supports
FDM printers struggle with overhangs beyond 45°. Design your parts to minimize overhangs, or orient them on the build plate to reduce support needs. This saves material and post-processing time.
Tolerances for Assembly
For parts that need to fit together, add 0.2-0.3mm clearance for FDM prints. Resin prints can work with tighter tolerances of 0.1-0.15mm.
Hollowing and Infill
Solid parts waste material and increase print time. Use appropriate infill (15-20% for decorative, 40-60% for functional) or hollow your designs with adequate wall thickness.
