3D printing supplies easy in secondary shaping

Abstract

The invention provides 3D printing supplies easy in secondary shaping. The 3D printing supplies are characterized by comprising, by weight, 40-80 parts of polycaprolactone, 10-25 parts of coated ceramic powder, 10-18 parts of superfine calcium carbonate powder, 5-10 parts of photosensitive resin, 3-8 parts of plasticizer, 1-1.2 parts of stabilizer, 0.8-1.2 parts of binding agent and 0.5-1 part of coupling agent. The 3D printing supplies have the advantages that the polycaprolactone is used to replace traditional ABS resin, polycarbonate and nylon to serve as the base material of the printing supplies, the melting temperature of the prepared 3D printing supplies is 60-70 DEG C which is much lower than the 200 DEG C melting temperature of printing supplies using the ABS resin, the polycarbonate and the nylon as the base materials, and the bottleneck that secondary shaping of 3D printing products cannot be achieve is broken through; the 3D printing products produced by the 3D printing supplies are good in impact strength, 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...
