What is LSAM?

LSAM (pronounced L-Sam) represents the industry-leading technology for large scale 3D printing of thermoplastic polymers. It utilizes unique patented technology to produce the highest quality printed structures available.

LSAM Series Machines

LSAM uses the "Near Net Shape" approach to part production where the part is first printed at high speed slightly larger than needed, then trimmed to the final size and shape. This is the fastest, most efficient method of 3D printing large structures. With LSAM, both printing and trimming can be done on the same machine.

LSAM can process parts from virtually any thermoplastic composite material including high temperature materials that are ideal for molds and tooling. Its unique printing system produces parts that are solid, fully fused, vacuum tight and virtually void free, making it a full-fledged industrial additive manufacturing system intended for serious production.

The LSAM Difference

Part printed on LSAM's Patented Bead Board

The LSAM Print Process

LSAM prints a large bead at room temperature in a process which is an exercise in controlled cooling. A patented compression wheel totally fuses layers together, creating solid, virtually void-free structures that can sustain vacuum in an autoclave without add-on coatings.

  • Patented "Bead Board" virtually eliminates warping.
  • Compression wheel ensures superior layer fusion.
  • Precise bead dimensions measured in thousandths of an inch.
LSAM machines are built from steel plate using slot and tab construction

Robust Industrial Machine Design

LSAM machines are large, robust industrial structures built from fully annealed steel plate using slot-and-tab construction. This results in an order of magnitude higher strength and stiffness than typical machine construction. The entire machine is volumetrically compensated for superior accuracy.

  • Dual gantries for simultaneous printing and trimming.
  • Laser-aligned and compensated on all axes.
  • Configurations available up to 100 feet in length.
Based on Thermwood's SuperControl

The Thermwood SuperControl

The LSAM control provides unique functions to make the print process easier and more capable. It automatically synchronizes the melt pump output to machine speed for perfect bead dimensions, and orients the compression wheel to the direction of motion, eliminating the need for complex programming.

  • Fully integrated temperature and pressure controls.
  • Automatic layer time control for consistent prints.
  • Simple, one-button operation for complex functions.
Thermwood's LSAM Print 3D is a true CAD slicing software that works within Mastercam.
