Resin 3D printing, known as vat polymerization, is represented by three technologies: SLA (Stereolithography), DLP (Digital Light Processing), LCD (Liquid Crystal Display). On this page, we will focus on DLP and LCD technologies, find more information about SLA on its dedicated page. Both of these resin 3D printing processes use a light source to cure the resin.
LCD vs DLP technology: What are the differences between these resin 3D printing technologies? The liquid resin is contained within a vat, or tank, cured against a build platform, which slowly rises out of the tank as the part is formed, layer by layer. These two 3D printing technologies are quite similar, but here is the main difference: the light source.
LCD printing: A UV light coming from an array of LEDs shining through an LCD flashes complete layers at the resin tank. A screen is used to mask the entire image, only revealing the current layer for curing. LCD 3D printing is a cost-effective resin manufacturing technique to get big and detailed functional parts. This 3D printing technology focuses on mass manufacture and large component 3D printing for resin materials thanks to 3D printers with larger build tray developed by Photocentric for example.
DLP printing: The digital light projector is the light source of DLP 3D printers. The DMD (Digital Micromirror Device) is a component made of thousands of micromirrors that are contained within a semiconductor chip matrix. These micromirrors are used for navigating the light beam projected by the digital light projector.

The variety of materials offered by LCD and DLP technologies makes them useful for many demanding applications. With this line of resins, you can choose between flexible, tough, or rigid resins. There is also a possibility to print translucent materials, specifically with DLP printing.
Are you looking for a 3D printing material with excellent thermal resistance, superior toughness, or a soft finish? These resin materials will be perfect for engineering and mechanical projects, automotive parts, or consumer goods, from prototyping to production. Some of these resins will allow the creation of large-scale objects. They are ideally suited for mass production thanks to the size of the build tray of their machines.
Similar to SLA, DLP is commonly used to generate highly detailed artwork, non-functional prototypes, and accurate finished parts.
