But speaking of molding utility, DLP technology is more complex and more adaptable for the dental or Jewelry mold.
Resin 3d printing is known for its great ability to achieve very nice, highly detailed parts, all thanks to a technology called vat polymerization.
Of course, both of them are used resin and light source to make parts, the comparative difference mainly is the light source type which use to cure the resin.
The process An SLA 3D printer consists of a vat (a resin tank), a build platform, and an elevatorâ used for moving the build platform upwards or downwardsâ a light source and a pair of galvanometers.
When starting a 3D print on a âtop-downâ SLA 3D printer, thereâs a single layer of resin on the build platform.
A DMD contains hundreds of thousands or even millions of small micro mirrors that direct the light and create the pattern of a layer.
