preparation example Construction

[0037] According to the first aspect provided by the present invention, the preparation method of 3D printing material comprises the following steps:

[0038] Step 1, preparing the prepolymer: dissolving the photosensitive resin polymer monomer, photoinitiator and terminator in a solvent, and performing a prepolymerization reaction at a certain temperature to obtain a prepolymer, so that the viscosity of the prepolymer is 100~ 50000cps.

[0039]In the present invention, before preparing the 3D printing material, the photosensitive resin polymer monomer, the photoinitiator and the terminator are made into a viscosity of 100-50000 cps so that the follow-up reaction is fast, and the prepared 3D printing material has excellent performance.

[0040] The present invention does not specifically limit the solvent used, it is preferred not to react with the photosensitive resin polymer monomer, photoinitiator or terminator, such as aromatic hydrocarbon solvents, aliphatic hydrocarbon s...

Description

technical field [0001] The invention relates to the field of material chemistry, in particular to a method for preparing 3D printing materials. Background technique [0002] 3D printing is hailed as another industrial revolution that subverts traditional manufacturing. Its molding process is: first design the required computer three-dimensional curved surface or solid model by software, and then layer it according to a certain thickness according to the process requirements, transform the original three-dimensional electronic model into two-dimensional plane information, and then convert 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 a plane processing manner and makes them automatically bonded a...
