Abstract
Methods and apparatuses for making laminated objects from composite materials are shown and described. An adhesion reducing material is applied with a moving printhead to the interfaces between object sections and waste sections of the layers of the objects to facilitate damage-free removal of the waste sections from the object sections. A rotating build platform allows the objects to be formed with the fibers of adjacent layers oriented at non parallel rotational orientations relative to one another. In certain examples, the adhesion reducing material is applied between opposing surfaces of layers wherein one surface is an object surface and the opposing surface is a waste surface. An infrared preheater preheats the side of a current layer being applied to a previous layer to a temperature sufficient to cause the composite adhesive to bond layers together. The infrared preheater and a pressure roller define a lamination assembly that traverses along a travel axis during a lamination operation.
