Thermwood Corp. offers a line of additive manufacturing (AM) systems for the production of large to very large reinforced thermoplastic composite parts. The Large Scale Additive Manufacturing (LSAM) line uses a two-step, near-net-shape production process. First the part is 3D printed, layer by layer, to slightly larger than the final size, then it is trimmed to its exact final size and shape using a CNC router.  Both printing and trimming happen on the same machine, using two different gantries.

Although suitable for producing a variety of components, Thermwood’s LSAM is used for producing large to very large industrial tooling, masters, patterns, molds and production fixtures for a variety of industries including aerospace, automotive, boating, foundry and thermoforming. The system is said to offer lower costs and shorter build cycles for production tooling. 


  • High-Frequency Production

    The additive process that grew out of ultrasonic welding provides an efficient way to produce complex work, including parts with embedded components and even parts made from dissimilar metals.

  • Thermwood 3D Prints Large Boat Hull Pattern

    Thermwood’s large-scale additive manufacturing (LSAM) technology enabled the fabrication of a 3,000-lb plug for a boat hull mold. The project illustrates how 3D printing could help reduce fabrication costs for marine composites. 

  • Why Robots and Additive Manufacturing Go Together

    3D printing and robots enable one another. We miss the possibilities of one if we do not consider the other. The combination includes AM for end effectors, robots for 3D printing parts, and different modes of metal and plastic production.
