Abstract: The present invention provides a composition for 3D printing, a process for preparing the same and an article thereof. By the solidifying method of UV irradiation, 3D printing is implemented. During said implementation, there is no need of high temperature heating, thus energy consumption is reduced, and there is no need for special solvent, thus harm to the environment is reduced. Meanwhile, the present invention uses micro-nano powder as the main material and polymer resin as adhesive, and at the same time, adds irradiation sensitizer. After electron beam irradiation, the polymer resin forms three-dimensional crosslinked network, thereby the strength, heat resistance and chemical resistance are improved after resin adhesion. Additionally, the present invention, by the addition of UV crosslinking agent, and by UV irradiation, cross-links the unsaturated resin after extrusion in 3D printing to form three-dimensional network structure, thus greatly improves the heat resistance, chemical resistance and mechanical strength of the shaping material, and makes the unsaturated resin have broader application prospects in 3D printing material.

Abstract: Provided is a 3D printing method and system using a near-infrared semiconductor laser as a heating source. The 3D printing system includes a printing spray head (4). In the 3D printing process, a laser beam is output by the near-infrared semiconductor laser to form a laser spot, which scans in an arbitrary path to cover a relevant area of a printed material for in-situ heating, thereby realizing the “asynchronous” printing mode. The near-infrared laser has higher penetration depth compared with a mid-infrared laser, so that the printing method using a near-infrared semiconductor laser as a heating source can be flexibly compatible with various printing platforms and the working process of the laser in the formed printing system can be decoupled from the 3D printing process of an article.
