Design Guidelines

Best practices to ensure your parts are manufacturable and cost-effective.

CNC Machining

  • 1

    Avoid Deep Pockets

    Deep pockets require long tools which can chatter. Keep depth-to-diameter ratio under 4:1.

  • 2

    Add Fillets to Internal Corners

    CNC tools are round. Internal corners must have a radius. Recommended minimum radius: 1mm.

  • 3

    Limit Thin Walls

    Thin walls can vibrate or break. Minimum recommended thickness: 0.8mm for metals, 1.5mm for plastics.

3D Printing (FDM/SLA)

  • 1

    Watch for Overhangs

    Angles greater than 45° usually require support structures, affecting surface finish.

  • 2

    Minimum Wall Thickness

    Ensure walls are at least 1.0mm thick to prevent warping or failure during printing.

  • 3

    Hollow Out Parts

    Reduce material usage and print time by hollowing out thick sections (with escape holes for resin/powder).
