This is a Proton Zero small scale SLA printer. It has its proprietary slicing software, and the file format is pw0. The file has to be copiped to a USB drive to print.
Stereolithography (SLA) 3D printers use a process called photopolymerization, where a UV laser or light source is directed at a vat of liquid resin. The light selectively cures and hardens the resin layer by layer to create the final object. The use of liquid resin, which is photosensitive, allows for high precision and smooth surface finishes. This material typically includes a base monomer, a photoinitiator, and various additives to enhance performance.
SLA printers can achieve very high resolutions, typically in the range of 25 to 100 microns, making them suitable for producing intricate details and fine features that FDM might struggle with. The parts produced by SLA printers have exceptionally smooth surfaces with minimal post-processing required, which is beneficial for applications requiring fine detail. However, parts produced with SLA printers may require post-curing under UV light to achieve full material properties and mechanical strength. Also, after printing parts typically need to be cleaned in an alcohol bath to remove any uncured resin. This step is crucial to ensure the quality and longevity of the printed parts.
SLA printers generally have a smaller build volume compared to FDM. This is partly due to the requirement for a controlled environment and the limitations of the laser system.
