Think critically
Beyond strength, how might build orientation affect other properties like surface finish, print time, or the need for support structures?
Design Principles
"Material properties in additive manufacturing are process-dependent and anisotropic; optimize build orientation for performance."
Understanding how layer orientation affects material properties is crucial for designers and engineers selecting additive manufacturing processes. This knowledge allows for the strategic design of parts that can withstand specific loads and stresses, leading to more reliable and performant products.
What This Means for Your Design
How you stack the layers when 3D printing changes how strong the object is. Stacking them in a certain way makes it stronger for specific uses.
