Method for rapidly removing 3D printing support

Abstract

The invention discloses a method for rapidly removing a 3D printing support. According to the main achieving manner of the method, a medium material printing head is used for printing a layer of easily degradable material before and after support printing, the support and a component are isolated through the medium material, the component and a substrate are isolated through the medium material, and the substrate and the support are isolated through the medium material. After component printing is over, a model is taken down, the medium layer is degraded, the medium material at the above part is dissolved, and the support structure naturally disengages from the surface of the component. The method is applicable to FDM, 3DP and other 3D printing technologies in which supports need to be added, support removal is fast and efficient, the component surface quality is not affected, the material cost is low, and a forming system is simple in structure.

AI Technical Summary

Benefits of technology

This invention relates to an improved method for removing supports from components during fabrication processes that can improve their overall performance without affecting its appearance or causing damage over time due to changes made between them. It also includes reducing the size of the supporting part while maintaining good surface qualities such as smoothness and low cracks on metal surfaces. Additionally, it simplifies the process of creation and assembly of these structures with minimal effort needed compared to traditional methods like welded connections. Overall, this technology improves efficiency and reliability in component production.

Problems solved by technology

This patented describes three technical techniques described in the field called AM technologies - Direct Layer Spray Making Technology ("DLSM"), which allows creation of precise objects through controlled dispensation of liquid droplets onto specific areas without requiring complicated steps like adding supporting elements during production processes. These advancements include reducing complexity, eliminating unnecessary supports, improving efficiency, speedup, cost savings, enabling customization, improved quality, and increased flexibility in product design.
