3D printing supplies easy in secondary shaping

Abstract

The invention provides a 3D printing consumable material which is easy to secondary plasticity, which is characterized in that: it includes the following raw materials in parts by weight, 40-80 parts of polycaprolactone; 10-25 parts of coated ceramic powder; 10-25 parts of superfine calcium carbonate 18 parts; 5-10 parts of photosensitive resin; 3-8 parts of plasticizer; 1-1.2 parts of stabilizer; 0.8-1.2 parts of adhesive; 0.5-1 part of coupling agent. The 3D printing consumable of the present invention uses polycaprolactone instead of traditional ABS resin, polycarbonate, and nylon as the plastic base material of the printing consumable, and the melting temperature of the prepared 3D printing consumable is 60-70°C, which is much lower than that of ABS resin , polycarbonate, and nylon have a melting temperature of 200°C, breaking through the bottleneck of secondary plasticity of 3D printed products; at the same time, the prepared 3D printed products have excellent impact resistance, durability and layer adhesion.

Description

technical field [0001] The invention relates to a 3D printing material, in particular to a 3D printing consumable which is easy to secondary plasticity. Background technique [0002] 3D printing is a rapid prototyping technology, known as the core technology of the "third industrial revolution". The complex forging process can get the final product, which can realize structural optimization, material saving and energy saving in production. [0003] Material is the material basis of 3D printing, and it is also the bottleneck restricting the development of 3D printing. At present, the materials used in 3D printing are all from industrial synthetic materials. The plastic base materials are mostly ABS resin, polycarbonate, nylon, etc., and their melting temperatures are all in the Above 200°C, it is not easy to deform at low temperature, and the development of 3D printing technology encounters a bottleneck in the production of 3D printing products that require secondary deforma...
