What is DLP Printing?

There are different types of 3D printing methods. We have mostly been featuring FDM (Fused Deposition Modeling) printing, a method that involves material extrusion. You are well familiar with how it works: it extrudes the melted filament from its hotend, creating the print layer by layer.

On the other hand, DLP printing works in a completely different way. Learn more about DLP printing and how it can produce prints with a smoother finish and higher resolution at a much faster rate.

What is DLP Printing?

DLP (Digital Light Processing) printing is a form of vat polymerization. It requires a liquid photopolymer resin material that can solidify into different patterns under a light source while its build plate moves up and down incrementally. Its process makes printing faster since a whole layer can be solidified simultaneously, thanks to the light source it uses called digital light projector screen technology.

The projector works together with a digital micromirror device (DMD). It contains up to millions of small micromirrors that direct the light that creates the pattern of a layer on the bottom of the resin tank. The resolution of an object depends on the number of micromirrors of the DMD.

DLP Printing: Advantages & Disadvantages over FDM Printing


  • Smooth finish: DLP printers have a small minimum feature size that allows them to create parts with a smoother finish. With FDM printers, you have to use special filament blends or do post-processing to get smooth prints.
  • High resolution: DLP printing is only limited by the micromirrors that its DMD is equipped with. The more micromirrors your printer has, the better the resolution your object will have. If you want to create incredibly detailed and intricate objects, DLP printing is your best bet.
  • Faster printing speed: Each layer can be solidified in one go with DLP printing. FDM 3D printers have to extrude melted material to build each layer upon layer, going from one end to another.


  • Brittle parts: If you’re creating structural or functional components that require strength, then DLP printing is not for you. DLP-printed parts are brittle.
  • Complicated to use: There are far too many different processes and starting materials involved with DLP printing. Meanwhile, FDM printers are easier to set-up and start printing with.
  • More expensive to use: There are many materials to use and there are limited suppliers of resins in the country so there isn’t a lot of choices.
