What Is DLP? DLP, or digital light processing, is a 3D printing technology that projects each layer, creating an illuminated plane where photopolymerization occurs. Unlike SLA, restricted to a single spot, the moment the light hits the resin, the whole layer is formed at once during DLP printing. A LCD screen creates a digital mask of each layer that functions as a stencil of the object that is being printed and allows LED ultraviolet light to pass thru and cure the resin.


Why DLP? Products printed using DLP are highly-detailed and require no sanding! Just primer, paint and you're done!
