Designing for Additive

Guidelines & Limitations for OEM Ceramic Components

Considering additive manufacturing for your ceramic OEM component? While there are a few limitations that may prevent additive from being employed, there are far more loose guidelines you should carefully weigh against the ceramic component’s overall geometry and its application requirements. Design evaluation by Ceramco's engineering team is part of every RFQ submittal.

Additive Design Limitations

Parameters which Ceramco Additive strives to avoid depending primarily on the OEM ceramic part's size, mass, and/or bulk:

Additive manufactured alumina bone screw implantable deviceEnvelope

  • Maximum L x W x H overall dimension of part is 75 x 47 x 235 mm

Thickness

  • Maximum 6.35mm walls in any area
  • Minimum 0.5mm walls

Other Parameters

  • Avoid fully enclosed cavities or porous structures

Additive Design Guidelines

Additive manufactured alumina valve parts for fluid meteringAn optimized OEM ceramic component design for additive manufacturing includes considering and (whenever possible) following these recommendations:

  • Avoid highly eccentric geometries or large overhangs
  • Avoid large and abrupt changes in cross section
  • Avoid sharp corners, especially internal
  • Maintain aspect ratio below 3:1 (height to base diameter or width)
  • Keep wall thickness between 2mm and 4mm
  • Keep bores, holes, slots, and grooves as large as design will permit
  • Design internal features and passageways to ensure air and/or fluid can pass through

Conclusions

Successful additive manufacturing of your OEM ceramic component is highly dependent upon its geometry. The design evaluation Ceramco provides as part of the RFQ helps assist its customers in determining the adjustments and revisions necessary, moving their components from the virtual space to reality.
