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.
