Abstract

A method for making a part, the method comprising: (a) providing an uncured upper layer on a part, a substrate, a workpiece, a support platform, or a base layer, wherein the uncured upper layer comprises resin and also comprises fibers, particles, powder, and/or electronic devices; (b) optionally providing a new uncured upper layer on the uncured upper layer provided in step (a), whereby the uncured upper layer provided in step (a) becomes an uncured lower layer, and wherein the new uncured upper layer comprises resin and also comprises fibers, particles, powder, and/or electronic devices; (c) curing the uncured upper layer and/or the uncured lower layer after step (b) using an electron beam; (d) after step (c), providing a new uncured upper layer on the cured or uncured upper layer, whereby the cured or uncured upper layer becomes a cured or uncured lower layer, and wherein the new uncured upper layer comprises resin and also comprises fibers, particles, powder, and/or electronic devices; (e) optionally curing the lower layer resulting from step (d) if the lower layer is uncured to yield a cured lower layer; (f) after step (e), optionally providing a new uncured upper layer on the uncured upper layer provided in step (d), whereby the uncured upper layer provided in step (d) becomes an uncured lower layer, and wherein the new uncured upper layer comprises resin and also comprises fibers, particles, powder, and/or electronic devices; (g) after step (f) curing the uncured upper layer and/or the uncured lower layer(s) after step (f) using an electron beam; and (h) optionally repeating steps (d) through (g) a number of times to form a desired number of cured layers.
