AI Technical Summary

Technical Problem

Existing solvent degreasing technology for semi-solid 3D printing is inefficient, especially in complex structures where degreasing is incomplete, and the accumulation of solvent concentration leads to a decrease in efficiency, which limits mass production.

Method used

The integrated liquid replenishment module and solution self-circulation module enable simultaneous degreasing and online recovery and recycling of degreasing solvent during the green part printing process. Through multi-axis motion control and computer regulation, the degreasing solvent parameters are precisely adapted.

Benefits of technology

It significantly improves degreasing efficiency and quality, shortens the molding cycle, saves solvent raw materials, reduces environmental pollution, and lowers production costs.
