Beschreibung
Zusammenfassung:	The invention discloses a high-precision 3D printing thermochromic material, a preparation method and an application method thereof. The material comprises the following components in percentage by mass: 15%-60% of cyclotrimethylolpropane acrylate, 10%-70% of ethoxylated trimethylolpropane triacrylate, 5%-20% of acrylamide morpholine, 0.5%-15% of thermochromic powder, 0.5%-5% of a photoinitiator and 0.05%-2% of a light absorber. According to the thermochromic material for 3D printing, the thermochromic powder and the photosensitive resin are uniformly fused, so that a three-dimensional formedobject is high in precision, smooth in surface and free of cracks, and has reversible thermochromic performance. The material is manufactured by adopting a 3D printing technology, and has a huge application prospect in the aspect of anti-counterfeiting identification of a 3D structure. The preparation method is short in production period, time-saving, labor-saving and easy for industrial production. 本发明公开了高精度3D打印热致变色材料及其制
