Problems solved by technology

In engineering plastics, polystyrene, polyethylene, polypropylene, ABS, nylon 66, and polycarbonate are generally used as basic materials, but these materials have long molding cycles, easy brittleness, poor heat resistance, and low temperature in dry state and low temperature. Poor impact resistance and other issues are not suitable for rapid prototyping technology

Description

technical field [0001] The invention relates to a rapid prototyping material, in particular to a rapid prototyping material containing nanocellulose and a preparation method thereof. Background technique [0002] Rapid Prototyping (RP) technology is an advanced manufacturing technology developed in the 1990s. It is a general term for rapid manufacturing of three-dimensional physical entities of arbitrary complex shapes directly driven by CAD models. Rapid prototyping has completely subverted the traditional method of processing parts. Compared with traditional processing methods, it has the advantages of digital manufacturing, high flexibility and adaptability, and rapidity; it also realizes the three-dimensional geometric figures and makes the design figures quickly become real objects. It solves the visible and intangible problems in CAD design, shortens the cycle of new product design evaluation, and has been widely used in automobiles, machinery, aviation, electronics, c...
