Abstract

The invention relates to a low-melting-point 3D printing material and a preparation method thereof. The 3D printing material has a melting point of 60-150 DEG C, is free of the problem that the final product performance is affected due to large shrinkage and is environment-friendly, non-toxic and odorless and free of ultrafine particles during printing process. The printing material comprises the following components: a toughening agent, wax, tackifying resin, stearic acid, an antioxidant, a pigment and the like and can be applied in industries such as dewaxing casting.

Description

technical field [0001] The invention relates to a low melting point 3D printing material and a preparation method thereof, belonging to the field of rapid prototyping materials. Background technique [0002] Rapid Prototype (RP) technology is an advanced manufacturing technology that developed rapidly in the 1990s, and is a key technology serving the development of new products in the manufacturing industry. It plays a positive role in promoting product innovation of enterprises, shortening the development cycle of new products, and improving product competitiveness. Since the advent of this technology, it has gradually been widely used in the manufacturing industry of various countries in the world, and thus gave birth to an emerging technology field. The current rapid prototyping technologies mainly include Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS), Stereo Lithography Apparatus (SLA), Laminated Object Manufacturing (Laminated Object Manufacturing) ...
