喷蜡材料可打印性研究及蜡模尺寸精度控制OA

Wax jet 3D printing offers a new approach for the rapid fabrication of complex wax patterns.This study takes a turbine bladed disc as the investigation object to evaluate the printability of the droplets by testing the rheological properties,surface tension,and other thermophysical characteristics of the wax material;based on this,a multi-zone coordinated deviation and deformation control method was proposed,in which the dimensions of the reference zone remain unchanged,and a combination of uniform scaling and reverse deformation compensation strategies was applied to control the shrinkage and deformation during the wax pattern forming and cooling processes at the design stage.The results show that the Z value of the selected wax material at the printing temperature falls within the appropriate ejection range,indicating good printability;after optimization,the overall dimensional deviation of the wax pattern can be consistently controlled within±0.1 mm,and the deformations in key areas such as the blade tips are effectively suppressed.This study provides a theoretical basis and technical support for the rapid and high-precision manufacturing of wax patterns using wax jet 3D printing.
