Synthesis of Hyperbranched Polymer for 3D Printing

Main observation and conclusion 3D printing has been developing rapidly in recent years owing to its application in academic and industry areas, but the poor mechanical property of printing materials limits its application. Herein, a photocurable resin with good mechanical property was obtained based on hyperbranched polymer synthesized through the reaction of carboxylic acids with isocyanates catalyzed by magnesium stearate. Three kinds of...
