Description

Technical field [0001] The invention relates to a printing material, in particular to a polyacrylate resin 3D printing material and a preparation method thereof. Background technique [0002] 3D printing is known as another industrial revolution that subverts traditional manufacturing. Its forming process is: first design the required computer three-dimensional surface or solid model by the software, and then layer it according to a certain thickness according to the process requirements, and turn the original three-dimensional electronic model into two-dimensional plane information. The layered data is processed to a certain extent, the processing parameters are input, and the numerical control code is generated: under the control of the microcomputer, the numerical control system sequentially processes each thin layer in an orderly manner in a plane processing mode and makes them automatically bonded and formed. 3D printing technology It is still in its infancy in China, with ...
