The Changing Shape of Manufacturing

Topology optimization and additive manufacturing go together. The complex, organic form that might be the most material-efficient choice for a part generally cannot be produced conventionally. However, additive manufacturing puts optimal forms within reach.

Material Strength Affects Part Weight in Additive Manufacturing

Material properties will have even more significance in additive manufacturing than in previous part-making processes. Taking advantage of the strength of one material over another can permit an internal redesign that reduces the weight and cost of the part.
