Design for Additive: the win is fewer assemblies and moving mass — not “freeform” alone
EOS outlines the shift from subtraction-first CAD to additive thinking: consolidation, integrated functions, and optimization buyers feel as reliability and total cost.
Many parts still arrive as “a solid to lighten,” designed for CNC or casting with 3D printing requested at the end. EOS’s DfAM perspective starts from function and load paths — letting additive join what used to be an assembly.
From single parts to system logic
DfAM is not only complex shapes: it redraws boundaries between components. When two metal parts become one printed body with tailored density or fiber paths, qualification changes — but a sub-assembly can disappear.
EOS stresses collaboration across design, process, and post-processing: CAD choices drive distortion, supports, and local mechanical behavior.
Weight, inertia, and motion cost
For moving systems, saving mass along the load path can matter more than shaving material dollars. Topology-style lightening is expensive from solid billets; additive can integrate it when the process is chosen early.
What to ask your supplier
Share interface constraints, loads, environment, and acceptance criteria — and explicitly request a DfAM proposal. Not every geometry belongs on a printer; when it does, the margin is often in joint work before the first trial build.
