DLP, or Digital Light Processing, 3D printers are a type of 3D printing technology that uses a digital light projector to cure a liquid resin layer by layer, creating a 3D object. Here's a brief overview of DLP 3D printers:

How DLP 3D Printers Work:

Resin Container:

DLP 3D printers use a vat of liquid photopolymer resin. This resin is photosensitive, meaning it solidifies when exposed to light.

Digital Light Projector (DLP):

The digital light projector at the core of the system projects a layer of the 3D model onto the liquid resin surface. This image is often a cross-section of the object being printed.

Layer by Layer Building:

The exposed resin cures and hardens upon contact with the projected light. The build platform then moves slightly, and the process is repeated for each layer until the entire object is formed.

Curing and Finishing:

Once the printing is complete, the object is typically removed from the resin vat. Depending on the specific printer and resin used, additional post-processing steps such as cleaning and curing may be required.

Advantages of DLP 3D Printing:


DLP printers can be faster than some other 3D printing technologies because an entire layer is cured at once.

High Resolution:

DLP printers often provide high-resolution prints due to the precision of the digital light projection.

Smooth Surface Finish:

The layer-less curing process can result in smoother surface finishes compared to some other 3D printing methods.


DLP 3D printers are capable of producing detailed and intricate designs, making them suitable for applications in jewellery, dental, and other industries where fine details matter.


Resin Selection:

The choice of resin is critical and can affect the mechanical properties, color, and post-processing requirements of the final print.

Build Size:

DLP printers may have limitations in terms of the size of objects they can print. Consider the build volume when choosing a DLP 3D printer.


Some post-processing steps, such as cleaning and curing, are often required to achieve the desired properties in the final print.

Popular DLP 3D printer manufacturers include Formlabs, Anycubic, and Peopoly. When selecting a DLP printer, it's essential to consider your specific application requirements, the type of resin you'll be using, and your budget.
