![]() ![]() Both technologies rely on the controlled emission of UV radiation on a vat of liquid resin, turning into a solid polymer according to a pre-defined model loaded into the slicer software. In the current context of 3D printing, there are two predominant technologies of resin-based 3D printing: Stereolithography (SLA) and Digital Light Processing (DLP). This process repeats until the whole model has been recreated. This means that the process relies on a layer-by-layer building process where one layer forms molecular bonds with the succeeding layer. When exposed to UV radiation, these monomers quickly form molecular bonds with each other and turn into a solid polymer.ģD printing using resins is also an additive process, just like FDM printing. The liquid resin used in 3D printing is typically composed of either epoxy or a combination of acrylic and methacrylic monomers. When the time comes that you need to choose between filament and resin, what’s the advantage of one over the other? Will a resin-based 3D printer be viable for the desktop-scale 3D printing hobbyist? What is resin-based 3D printing?Īs its name implies, resin 3D printing uses plastic resin as the raw material, in contrast to the filament used in FDM technology. In this article, we take a detailed look at how resin-based 3D printing works and its pros and cons. While filament-based FDM 3D printing still dominates the casual 3D printing market, it’s only a matter of time before resin-based 3D printing technology also becomes accessible. ![]() 3D Insider is ad supported and earns money from clicks, commissions from sales, and other ways.ģD printing has become so common that we have now reached a point where we have the luxury of choosing between alternative technologies.
