Concept:DLP is a 3D printing method that uses a digital light projector to cure resin layer by layer.
Explanation:DLP stands for Digital Light Processing.
It works by projecting an entire image of a layer onto liquid photopolymer resin.
The exposed resin hardens instantly, forming one complete layer at a time.
This makes DLP faster than Stereolithography (SLA), which cures point by point with a laser.
It is ideal for detailed items like jewellery moulds, dental models, and miniatures.
