Design Guide
Design Advice
- Supports as Heat Sinks: In SLM, supports act as critical heat sinks to dissipate intense laser heat. Design parts with overhang angles greater than 45° to minimize supports, and ensure thick sections are anchored to the build plate to prevent warping.
- Self-Supporting Internal Channels: For internal cooling channels or holes larger than 8 mm, use teardrop or diamond shapes instead of circular ones. This geometry allows the feature to be self-supporting, ensuring easy removal of unfused powder.
- Minimum Wall Thickness & Fillets: Maintain a minimum wall thickness of 0.5 mm for functional features. Avoid sharp internal corners by adding fillets (minimum R 0.5 mm) to distribute stress and prevent cracks caused by rapid heating cycles.
