CBAM: Composite-Based Additive Manufacturing

CONFIDENTIAL 2

100x Faster Scales to make parts in minutes or seconds.

10x Stronger Fiber-reinforced composites, stronger than other 3D printing materials.

Widest Range of Materials Ones that industries actually use.

CBAM takes the power of 3D printing to high-volume production

Game-changing, patented technology based on years of research in materials science.

How CBAM works

Feed fiber sheet into inkjet printer.  

Load CAD slices into printer and print layer shape of object on fiber sheet.  

Deposit polymer powder onto printed sheet which sticks to where the sheet is wet from print fluid.  

Remove dry powder; only powder stuck to the print fluid remains.  

Stack sheets in order, heat to melting T° of polymer, and compress stack to final part height.  

Remove un-bonded portions of sheet fibers to net final part.
