Elegoo Mars 4 DLP vs. Anycubic Photon D2 resin 3D-printers

Elegoo announced a new resin 3D-printer based on DLP technology. This is a move from the technology that they are very familiar with, LCD or MSLA 3d-printers. This is about one and a half years after Anycubic launched its first resin DLP 3D-printer on Kickstarter. By Anycubic has launched already a second version of their affordable DLP system, the  Anycubic Photon D2 DLP. Elegoo is now the second 3D-printer manufacturer that supplies an affordable DLP printer. Let’s see what it is and if this is significant for the resin 3D-printing industry.


Elegoo Mars 4 DLP vs. Anycubic Photon Ultra D2 DLP

There is not that much of information online, but some key metrics are available and listed below.

  Elegoo Mars 4 DLP Anycubic Photon Ultra D2
DLP Chipset 2K 2K 
Pixels 2560 * 1440  2560 * 1440 
Print size (L x W x H) 132* 74.7 * 150 mm 131 * 73 * 165 mm
Pixel size ~0,080 mm 0,051 mm 
Light intensity 4mW/cm2* 3mW/cm2* 
  • * light intensity of the Elegoo Mars 4 DLP is from the manufacturers marketing material while the Anycubic Photon D2 was measured at the Liqcreate R&D laboratory.


According to Anycubic and Elegoo, both printers have a 2K DLP projector with a resolution of 2560 * 1440 pixels. The reason to bring this up is that Anycubic was famous for printing an extremely affordable 720P (worse resolution) DLP chip to the market. when upgrading this to a 2K chip it will be much more expensive. But when they actually don’t use a 2K DLP chip, and manipulate the same 720P with an XRP actuater, it can get a in theory a “higher” resolution for an affordable price. Read all about XRP actuater technology here. The reason we suspect it is because All3DP wrote this: “Anycubic also claims its gray anti-aliasing algorithm for the Photon D2 can achieve “printed objects with life-like precision”, which hints on XRP technology. Same story goes for Elegoo as their specifications are almost similar of their Mars 4 compared to the Photon D2 DLP printers.


About the Elegoo Mars 4 DLP resin 3D-printing technology

Digital Light Processing (DLP) uses a digital light projector to directly project the entire layer image to the bottom of the resin tank, with the UV beam selectively projected by a digital micromirror device (DMD)  onto the given position to be cured. ELEGOO DLP projector adopts the LG high-performance LED light source + 13-layer lens set design, with light intensity up to 4mw/cm2 and light uniformity up to 95%, coupled with 95% light transmittance tempered glass, which minimizes light scattering and light bleed. The result is greater print accuracy than LCD 3D printers with the same resolution.
