Problems solved by technology

[0003] Although there are many types of composite materials, no high-resilience composite materials are suitable for 3D printing consumables. PLA, ABS, nylon618, PVA and other single materials are mainly used as 3D printing consumables.

Abstract

The invention provides a 3D printing composite material which comprises the following components in percentage by mass: 50-80% of TPU, 20-50% of polyolefin and 0.1-5% of a compatilizer. The 3D printing composite material is applicable to 3D printing consumables and is easy to process and smooth in printing, and a printed product is excellent in mechanical property, stable in size and high in surface gloss degree. The invention further provides a method for preparing the 3D printing composite material and application of the 3D printing composite material.

Description

technical field [0001] The invention relates to 3D printing consumables, in particular to a high resilience 3D printing composite material and its preparation method and application. Background technique [0002] The existing 3D printing consumables can be roughly divided into hard materials, soft materials, and water-soluble materials. Hard materials mainly include PLA (polylactic acid), ABS (acrylic acid / butadiene / styrene terpolymer), nylon618, PC (polycarbonate), HIPS (polystyrene), PP (polypropylene), etc.; Soft materials mainly include PBAT (polybutylene adipate / terephthalate), TPU (thermoplastic polyurethane), etc.; water-soluble materials are mainly PVA (polyvinyl alcohol). Due to the shortcomings of the above-mentioned various materials, PLA is easy to degrade, and the material is easy to deform when the temperature is above 55°C; ABS is a common engineering plastic, which is easy to purchase but has a heavy odor and high deformation rate. PBAT degradable material,...
