Thermwood CLA Trim and Drill Vacuum Fixture Project

Posted by Duane Marrett on Wed, Oct 23, 2024

Tags: Video, Additive, Additive Manufacturing, CLA, Cut Layer Additive

Ever wondered how you can produce large format, near-net-shape parts faster and more affordably? Check out this innovative use of Thermwoodโ€™s Cut Layer Additive process in action!

Watch as CLA creates a Trim and Drill Vacuum Fixture using RAKU Tool SB-0497 with remarkable precision and speed. This method slashes production costs while maintaining top-quality results.  See how cutting layers, rather than printing them, is making large-scale manufacturing easier and more efficient than ever

Project Details:

  • Trim and Drill Vacuum Fixture made from RAKU Tool SB-0497
  • CLA Software Processing Time: 13 minutes 48 seconds
  • CLA Machining Near Net Shape Layers Time: 1 hour 4 minutes
  • Assembly Time: 2 hours with 2 employees
  • Total 5 axis Trimming Time: 35 hours

Cut Layer Additive is a powerful new additive approach that produces large format, near-net-shape parts at incredibly low cost, using a lower cost additive machine. Unlike large format additive printers (like Thermwoodโ€™s LSAM), the new process makes large parts from a variety of materials that canโ€™t be printed.

Cut Layer Additive parts are similar to large additively printed parts, in that they are essentially hollow structures made in layers. However, instead of printing the layers, they are instead cut from thick sheets.

Highlights from the recent IMTS show held in Chicago!

IMTS 2024 Recap

It was a pleasure to showcase our innovative technologies, including the LSAM (Large Scale Additive Manufacturing) Additive Printer 510, which printed live, high-temperature (350ยฐF) autoclave-capable aerospace tooling throughout the event!

Each day, we featured a different high-temperature material from leading 3DP material providers. Two tools were printed daily, each tool weighing 215 lbs and printed in 5 hours.

Purdue CMSC on hand at IMTS
We were also proud to highlight our collaboration with Purdue Universityโ€™s Composites Manufacturing & Simulation Center (CMSC). The printed autoclave tool incorporated Purdueโ€™s ADDITIVE3D simulation process to predict and compensate for shape changes due to residual stresses, interlayer bonding and deformation. Full scale tool samples showcasing vacuum integrity, surface quality and part precision were displayed for attendees.

Cut Layer Additive (CLA) Featured at IMTS

In addition, we featured our Cut Layer Additive (CLA) manufacturing process, a cutting-edge approach for creating tools, patterns and molds using sliced layer lamination. CLA enables the use of materials that are not 3D-printable and integrates features for vacuum, coolant and assembly โ€“ representing the future of mold manufacturing.
