LFAM (Large Format Additive Manufacturing) refers to industrial-scale 3D printing—most commonly using pellet extrusion systems—to produce large parts quickly and cost-effectively, typically for tooling, molds, and structural components. In LFAM, post-processing is essential because printed parts are only near-net shape; after printing, they undergo controlled cooling to reduce internal stress, followed by trimming and extensive CNC machining to achieve precise dimensions and smooth surfaces. Due to inherent porosity and rough layer lines, parts are often sealed with epoxy or resin and may be reinforced with composite materials like fiberglass or carbon fiber. Final steps include sanding, coating, and assembly, resulting in a finished component suitable for industrial use.
