The device is flexible to operate, by means of alternate action of cooling liquid and the heating part, effects of heating and cooling conditions on the volume of a metal material can be simulated respectively, and meanwhile, the alternate action of the cooling liquid and the heating part is in cooperation with temperature monitoring, so that obtained data is large in reference value andhigh in accuracy.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a device for measuring heat shrinkage parameters of metal materials for 3D printing simulation. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printing. Technical issues, during the 3D printing process, the metal material melts rapidly, and the volume change due to its inherent thermal expansion rate, the size of the volume change is related to the microstructure control, internal defect formation and 3D printing parts deformation during the metal 3D printing process For problems such as cracking, the traditional metal material heat shrinkage parameter measurement device has a single measurement function and low measurement accuracy. [0003] In order to solve the above problems, this applic...
