Preliminary study on volumetric 3D printing using visible light

Abstract

The realm of 3D printing has been a valuable aspect of manufacturing and mechanical engineering to which complex geometries have been made that might be otherwise highly costly or not feasible by other manufacturing methods. This is where volumetric 3D printing has been advantageous by generating complex geometry with no defects on the surface. The problem with the research done so far is the material used uses photoinitiators that photo-synthesize using ultraviolet (UV) light. The problem with this material is that it is attached to the destructive issues brought on by interacting with UV light, making some additives useless. To solve part of this problem, a solution to the material problem must be shown that a resin can be cured using visible light. This study has investigated the feasibility of novel manufacturing process termed, Visible Light Induced -Volumetric 3D Printing (VLI-V3DP) process, that resulted in successfully nding resin that can be cured using visible light in the 470 & 530 nm range. By curing simple geometry using visible light, one can formulate a resin that can sustain just about any additives that can meet any goal, whether it is organic or not.

“…With the rapid development of industrial manufacturing, China is facing challenges such as limited environmental resources, shortage of raw materials, and difficulties in manufacturing new materials. Additive manufacturing technology has emerged as a vital technique to address these issues, possessing several advantages such as speedy production of intricate and sizable items, preservation of resources, and eco-friendliness [1][2][3]. In metal additive manufacturing technology, laser metal deposition is an important method that can directly manufacture high-density and high-performance work pieces.…”
