This may one day allow for walls to be printed with conduit or ductwork already in place.Lena Smirnova 1 Brian S. Since there is no need for tooling, forms or dies, large-scale additive manufacturing allows each part to be unique, with no time penalty for added complexity or customization.Īnother interesting feature of large-scale additive manufacturing is the capability to produce complex components with internal voids. While reducing cost, this process leaves little room for customization. Most construction materials today are mass-produced on assembly lines that are designed to produce the same components. Because additive manufacturing builds layer by layer, using only the material and energy required to make a particular component, it's a far more efficient building process than "subtractive methods," which involve cutting away excess material – think milling a wood beam out of a tree.Įven common materials like concrete and plastics benefit from being 3D-printed, since there's no need for additional formwork or molds.
