Design Do’s | Design Dont’s |
Maintain uniform wall thickness Core out thick areas Design with a flat surface, lettering and threads Consider location of gates, ejector pins, and parting lines. | Walls should be no thinner than 0.1mm (0.0039 in.) Don’t design holes smaller than 0.1mm (0.00e9 inc) in diameter Dont design components over 12.55 mm (0.5 in.) thick and over 100 grams in mass Avoid designing sharp corners |
