MSLA
Also known as: msla · lcd · impresora de resina lcd · masked stereolithography
Short definition
MSLA is the resin printing technology that uses an LCD screen as a mask to cure an entire layer at once with ultraviolet light.
Full definition
A UV light array shines from below and the LCD screen lets light through only at the pixels matching that layer's cross-section. Because the whole layer cures at once, print time depends on the part's height rather than on how many objects sit on the platform: printing one miniature or twenty takes almost the same. It is the technology in practically every home resin printer, and resolution is expressed by the screen's pixel size. Typical exposure times run from 20 to 40 seconds on bottom layers and 1.5 to 3.6 seconds on normal ones.
Related terms
- SLASLA is the resin printing technology that traces each layer with a focused ultraviolet laser point by point, instead of projecting the whole layer at once.
- Resin3D printing resin is a photopolymer liquid that solidifies when it receives ultraviolet light, normally at a 405 nanometre wavelength.
- CuringCuring is the reaction by which liquid resin solidifies when it receives ultraviolet light, both during printing and in the finishing step afterwards.
