LSAM - Large Scale Additive Manufacturing
Advanced production systems that create industrial fixtures, molds (including high-temp), tooling, prototypes, and end products from a wide range of materials.
Large industrial “Near Net Shape” additive machines that can print and trim on the same machine.
Thermwood LSAM: A Game-Changer for D-J Engineering
With their Thermwood LSAM MT, D-J Engineering produces complex tooling in weeks instead of months, making the process faster, predictable, and repeatable.
Shaping the Future of Composites Manufacturing
Dr. Byron Pipes and Dr. Eduardo Barocio explain how their Purdue collaboration with Thermwood LSAM is driving large-scale 3D printing and industrial composites innovation.
Revolutionizing Large Scale Manufacturing
LSAM is engineered to dramatically accelerate production, reduce costs, and unlock new possibilities in large-part manufacturing.
Unprecedented Scale
Build massive parts and tools with print beds available up to 40 feet and beyond, enabling manufacturing on a scale previously thought impossible.
Two Processes, One Machine
Go from a printed near-net-shape part to a final, trimmed, high-precision product on a single machine, streamlining your workflow.
High-Temp Polymers
Process virtually any composite thermoplastic, with temperatures up to 450°C to produce strong, durable, and reliable parts for demanding applications.
Standard LSAM (Closed Configuration)
These are near net shape additive manufacturing systems that offer both print and trim on the same machine. They are configured with a fixed table, high walls, and a moving gantry or gantries, and can be fully enclosed to meet CE requirements.
Available Sizes: 10'x10', 10'x20', 10'x40', 15'x20', 15'x40'
The model numbers (1010, 1020, etc.) denote the table size in feet. While 40-foot lengths are common, even longer machines are possible.
Gantry & Control System
- Model 1010: A single gantry with both print and trim heads, allowing one operation at a time.
- Models 1020+: Dual gantries and dual controls, one for printing and one for trimming. This allows simultaneous printing on one end of the table while trimming on the other.
Advanced Capabilities
- Machines 1020 and larger can be equipped with a Vertical Layer Print System.
- This system enables printing parts as tall as the machine table is long on a moving vertical table.
LSAM MT (Open Configuration)
This machine is configured with both a print and trim head on a single fixed gantry mounted over a 10'x12' moving table. Like the 1010, this system can both print and trim, but not at the same time. The open configuration cannot be built to meet CE requirements.
Key Features
- Features a 10'x10' primary working area.
- An additional two feet of table length accommodates an optional Vertical Layer Print Table, allowing parts up to ten feet tall to be printed vertically.
- Utilizes the same powerful print and trim heads as all other LSAM machines.
- Also available as a "Print Only" machine for those with existing trimming capabilities.
LSAM Additive Printers
"Print Only" systems built around Thermwood's 40mm LSAM print head, offering highly capable machines at an attractive price point. These systems feature a single gantry, moving table configuration.
Available Table Sizes: 5'x5', 5'x10'
Configurations & Capacity
- The 5'x10' table is available as 5' wide with 10' motion or 10' wide with 5' motion.
- Standard single servo table drive accommodates parts up to 1,000 lbs.
- An optional second table drive increases max weight capacity to 2,000 lbs (10' wide table only).
- The 5' wide by 10' deep version supports Vertical Layer Printing for parts up to 10 feet tall.
Core Technology
- Uses the exact same print head and advanced Ultra 6 control as the largest LSAM systems.
- A rigid, structural steel gantry incorporates a fume extraction system with activated charcoal filters.
- Standard single hopper polymer dryer; dual hopper dryer available as an option.
- A full machine enclosure is available, allowing the machine to meet European CE standards.

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 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
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.
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.
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.
Industry-Leading Slicing Software
To address the lack of professional software for "Near Net Shape" printing, Thermwood developed a true CAD slicing software that works within Mastercam. It accepts geometry in every major CAD format and offers powerful, feature-rich programming capabilities.
- Automatically adjusts for unique machine print characteristics.
- Allows solid or sparse infill, variable boundary layers, and more.
- Programs incredibly complex parts by printing concurrent structures.
