3D Printing Material Torsion Testing Machine
Category：Torsion Testing Machine
Introduction
The 3D Printing Material Torsion Testing Machine is specially developed for PLA, resin, and metal printed specimens, and can measure mechanical properties such as torsional strength and fracture torque. It adopts precise servo loading technology to collect torque and torsion angle data in real time, automatically generate curves, and provide test reports. The equipment is easy to operate and is compatible with various printed specimens, meeting the testing requirements of new material development, product quality inspection, and laboratory testing in universities and research institutions.
Applications
Used for torsional strength, fracture torque, torsion angle, and mechanical performance testing of 3D printed materials such as PLA, resin, metal printing materials, and composite printed specimens. It is widely applied in 3D printing material research, product quality inspection, new material development, universities, and research laboratories.
