Support Structure Optimization for Overhangs
Optimization of support structures for overhangs in the additive manufacturing process to manage process heat and mechanical stresses.
Physico-Chemical Mechanism of Action
During additive manufacturing (e.g., SLS or SLA), overhangs generate high process heat and mechanical stresses that can affect the material. The support structures carry this load and prevent the overhang from collapsing or becoming defective.
Metallurgical Relevance & Welding Risks
Incorrect support structures can lead to uneven stresses that damage the material or cause cracks. This can result in defects in final part production and compromise product quality.
Workshop Practice & Action Guidelines
For optimal support structure optimization:
1. Use stable materials with high stress resistance.
2. Calculate the required load-bearing capacity based on process heat and mechanical loads.
3. Place the supports so they distribute the load evenly and avoid uneven stresses.
