It wasn’t long ago when makers on a tight budget were restricted to desktop FDM machines.

 .

Stereolithography, or SLA, is a resin-based 3D printing technology that offers unrivaled print quality when compared to FDM, but these machines were often priced in thousands and largely reserved for professionals and hardcore hobbyists.

 .

That all changed a couple of years ago when a steady, gooey trickle of desktop-sized resin 3D printers swept the consumer market by storm.

 .

For the first time ever, frugally-minded makers could access high-quality resin 3D printing at a fraction of the cost. How so? With a technology called Digital Light Projection (DLP). Unlike SLA technology, which utilizes a laser to harden liquid resin into a 3D model, the DLP process works by projecting the whole image of a layer into a vat of resin, effectively curing the material layer by layer until a solid object is created.
