Recently we discussed that 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. Learn more about the Elegoo Mars 4 DLP, compatible resins and 3D-printing parameters.
Please note that there are four different Elegoo Mars 4 resin printers. this article is specifically for the Elegoo Mars 4 DLP version and not the Mars 4, Elegoo Mars 4 Ultra and Elegoo Mars 4 Max, which are all LCD based MSLA printers.

Elegoo Mars 4 DLP comparison with the Anycubic Photon D2 DLP.
There is not that much of information online, but some key metrics are available and listed below.
| Â | Elegoo Mars 4 | Anycubic Photon Ultra D2 |
| DLP Chipset | 2K | 2KÂ |
| Pixels | 2560 * 1440Â | 2560 * 1440Â |
| 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*Â |
- * light intensity of the Elegoo Mars 4 is from the manufacturers marketing material while the Anycubic Photon D2 was measured at the Liqcreate R&D laboratory.
About the Elegoo Mars 4 DLP resin 3D-printing technology
Digital Light Processing (DLP) is using a digital light projector to expose the entire layer image to the bottom of the resin tank. By utilizing a micromirror device (DMD) to selectively project the UV light 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.
