Difference Between SLA and DLP 3D Printing
Stereolithography (SLA) 3D Printer
Stereolithography Apparatus (SLA) is the first 3D print online technology ever patented. It was copyrighted in 1984 by Charles Hull, the 'Father of 3D Printing.' AN SLA 3D printer uses a laser to selectively harden the liquid resin in the VAT to create a layer-by-layer object.
Digital Light Processing (DLP) 3D Printer
The 3D Printing online technology - Digital Light Processing (DLP) is also part of the VAT photopolymerization technology. It is similar in many respects to SLA 3D Printing service in India with a small but significant improvement. A DLP 3D printer uses liquid photosensitive resins that are cured when UV light is applied.
The critical distinction between these two 3D Print Online technologies is the light source, which determines the product's consistency printed on these devices. DLP 3D Printing service in India uses a digital projector screen to flash a single-layer graphic.
This means that a single sheet of printing is done with a single flash. Whereas in an SLA print, the laser traces the geometry by following the coordinates.
As a result, the DLP 3D printer is faster than the SLA 3D printer.
