In this Digital Demo, CNC and machinery specialist Thermwood (Dale, Ind., U.S.) outlines the features and benefits of its Large Scale Additive Manufacturing (LSAM) system to produce net shape and near-net shape tools, molds and parts for applications ranging from marine to defense to aerospace.

The Digital Demo includes a review of non-proprietary programs and projects in which LSAM was used to fabricate a fairing tool, an oil pan mold, structures for an autonomous bus, a helicopter blade mold, a boat hull master plug and more. Information is provided on the flagship machine, LSAM 1020, a high-wall machine available in a variety of size configurations.

You will also learn about LSAM MT, a lower-cost model that features a moving table, and LSAM 1010, another high-wall system. Thermwood product manager Scott Vaal also explains the resin heating and extrusion technology, called MeltCore, employed by in all LSAMs and summarizes how LSAM provides a consistent bead during material laydown.

Vaal also walks through the use a capabilities LSAM’s control system, resin drying technology, and the LSAM Print 3D slicing software. Finally, this Digital Demo summarizes the 5-axis finishing capabilities of LSAM, with a review of tools, tool changing, and segregation of machining processes from additive manufacturing processes.
