Abstract

A method of forming an article of manufacture comprises: a) forming a precursor to the article of manufacture using a first material comprising an actinic radiation curable composition comprising at least one cyanoacrylate and optionally at least one filler; b) actinically curing the precursor to form a cured precursor article comprising a cured actinic radiation curable composition; c) optionally forming an intermediate article of manufacture from a second material while using the cured precursor article as at least one of a support, a positive mold, or a negative mold for the second material; and d) heating the cured precursor article to a temperature sufficient to decompose the cured actinic radiation curable composition to form or isolate the article of manufacture. The method is suitable for the use of additive manufacturing in developing dental materials, jewelry, or high strength industrial products.
