STEREOLITHOGRAPHY USING COMPOSITION PROVIDING REDUCED DISTORTION |
摘要 |
An ultraviolet-curable liquid composition adapted to cure rapidly to a lightly cross-linked solvent-swellable three dimensional complexly-shaped polymeric thin-walled element constituted by heat-softenable solid polymer upon exposure to ultraviolet dosage in the range of 1-15 Joules per square centimeter and which possesses reduced distortion comprises, from 20% to 80%, of a resinous polyacrylate or polymethacrylate dissolved in a combination of 10% to 45% of a liquid polyacrylate or polymethacrylate, which is preferably trifunctional, and 10% to 45% of liquid N-vinyl monomer, preferably N-vinyl pyrrolidone. One of the foregoing polyacrylates or polymethacrylates is a polyacrylate and the other is a polymethacrylate so that good cure speed is accompanied by good distortion resistance. |
