What is resin 3D printing?
Resin 3D printing is an additive manufacturing process that uses liquid photopolymer resin materials to create highly accurate, precise, and complex objects. Layer by layer, liquid resin is selectively converted into solid form by a light source such as a laser or projector in a resin printer. Jewelry, dental models, complex models for prototyping, and small-scale production items are often created using resin 3D printing.
How does resin 3D printing work?
The resin 3D printing process, also called stereolithography (SLA) or digital light processing (DLP), involves curing layer-by-layer liquid photopolymer resin using UV light. While a projector in DLP spreads a pattern of UV light over the entire layer of resin and cures it all at once, SLA selectively solidifies the resin by tracing the shape of the object onto the surface of the resin. The build platform is lowered after each layer dries and this process is repeated until the entire object is finished. The final product is post-processed to remove excess resin and harden the material, which includes washing and curing.
What software is used for 3D resin printer?
The software used for resin 3D printers varies depending on the manufacturer and model. Chitubox, PrusaSlicer, Formlabs PreForm, and Autodesk® Meshmixer are some examples of popular software. Users of these softwares can prepare, cut and send 3D models to printers. Additionally, they provide features for changing print quality settings such as layer height, exposure time, and support structures.
Are resin 3D prints fragile?
Yes, 3D prints made from resin can be fragile. This is because resin prints use a special type of polymer that may be more brittle than materials like ABS or PLA. Additionally, the resin curing process can sometimes cause stress fractures or other types of damage that increase the likelihood of the print breaking.
