Large-scale machine demonstrates composites AM capabilities

Thermwood (Dale, Ind., U.S.) is exhibiting its additive manufacturing (AM) technology solutions through the demonstration of its LSAM AP 510 system and cut layer additive (CLA) system. Product features for the former include:

• Autoclave tools for aerospace composite layups, which are reported to enhance composites manufacturing processes with high-precision, reliable tools.
• Trim fixtures, said to improve efficiency in a users’ manufacturing workflow.

The company’s LSAM Additive Printer systems are single-gantry, moving table configurations and are available in two table sizes: 5' × 5' and 5' × 10'. The 5' × 10' table is available in two configurations, 5' wide with 10' of front to back motion, and 10' wide with 5' of front-to-back motion. Choice of configuration depends on several factors; fitting it existing factory floor space is one example.

The highly rigid tab and slot structural steel gantry also incorporates a fume extraction system that pulls print fumes through specially designed activated charcoal filters to remove them and “sweeten” the air.

LSAM Additive Printers use the exact same print head mechanism as all the others, including Thermwood’s largest LSAM systems, which means that they produce the same high print quality. They also use the same highly advanced Ultra 6 control with all its exclusive, patented print features and capabilities.

The systems come standard with a single hopper polymer dryer for applications that don’t change print material very often. For installations that print a wider variety of materials, a dual hopper dryer is available as an option.

An enclosure that surrounds the machine is also available. The machine with the full enclosure can also be built to meet European CE standards.

Thermwood is also demonstrating several tools from its CLA system, which can enable users to create large-format additive tools from materials that are unable to be printed.

The company’s team of AM representatives are available to discuss customers’ specific needs and provide detailed insights into the company’s technology and its applications.
