Thermwood (Dale, Ind., U.S.), which routinely applies for patent protection on additive manufacturing (AM) technology it develops for its LSAM large-format additive systems, has received all 32 official hard copy patents. The electronic copies were previously granted in 2021. 

In addition to these latest patents, Thermwood points to its large portfolio of patents already issued to cover the company’s large-format 3D printer (5 x 10-foot and larger) for reliable, repeatable production of completely fused, homogeneous printed structures from a variety of fiber-reinforced thermoplastic including those intended to operate at elevated temperatures. 

The LSAM technology is used in a wide variety of industries including aerospace, transportation, heavy equipment, foundry and large decorative structures. It is being used to produce a diversity of products including aerospace patterns, molds and tooling, heavy equipment foundry patterns, bus chassis, large valve body foundry patterns and trim tooling. It was even used to print what Thermwood says is the tallest 3D-printed structure in the world, the 92-foot-tall Al Davis Memorial Torch at Allegiant stadium in Las Vegas.

Thermwood offers a broad selection of patented equipment, including single and dual gantry, fixed and moving table configurations, with both print-only and print-and-trim systems, from 5 x 10-foot to 20 x 60-foot print envelopes.
