From the Manufacturer
Technology Leader in Large Scale Additive Manufacturing
Thermwood is a US based, multinational, diversified machinery manufacturer that markets its products through offices in 11 countries. Thermwood is the oldest manufacturer of highly flexible, 3 and 5 axis high-speed machining centers known as CNC routers.
Thermwood is also the technology leader in large scale additive manufacturing of thermoplastic composite molds, tooling, patterns and parts with its innovative line of LSAM (Large Scale Additive Manufacturing) machines that both 3D print and trim on the same machine. These are some of the largest and most capable additive manufacturing systems ever produced and are marketed to major companies in the aerospace, marine, automotive and foundry industries as well as military, government and defense contractors.
Thermwood embraces all aspects of the essential technology, the machine, the control and the driving software. This better integrates all aspects of state-of-the-art technology into superb products to meet the most demanding customer requirements.
Thermwood machines are designed to operate in real production environments 24 hours a day, 7 days a week, 365 days a year with minimal maintenance.

TCT Buyer Guidance
Questions for your Thermwood LSAM evaluation
What is the target part size? Thermwood's near net shape AM systems are available in a range of sizes catering to large parts. Integrated print-and-trim systems eliminate the need to move large parts between machines, reducing handling risk and improving dimensional accuracy.
What material performance do you need? Carbon-fiber-filled polymers deliver high stiffness-to-weight but require different processing parameters than unfilled grades. High-performance polymers (PEI, PESU, PPS) offer superior thermal and chemical resistance but at significantly higher material cost.
What is your throughput requirement? Deposition rates of 200--500 lbs/hr enable rapid production of large tooling, but cycle time also depends on the trim pass. Ensure you're evaluating total cycle time including both print and machining operations.
