I try and get the HD resin when possible, and everyone I've shown has been impressed with the level of detail that this printer + the resin have produced. Sometimes I'll get misprints, but I think that's pretty standard for any resin printer and 99% of the time it comes down to a handful of easy adjustments: - Exposure time for the bottom layer -- (I've also found that applying PTFE lubricant at the bottom of the resin tray and then letting it dry before adding resin in has really reduced sticking) - Resin type/quality (I haven't had tons of luck with clear resin, but all shades of grey, white, and translucent green have been great) - Tray leveling - Supports/angle of what I'm trying to print I must also say that their customer service is fantastic, and if you're in the warranty period and having issues, email them. They sent me very helpful videos which have resolved some issues (some issues were due to my own fault and a resin spill) and when following the instructions didn't help with a LCD screen issue, they sent me a replacement part (and a video of how to replace it). This was my first adventure in 3d printing and this printer was super user friendly! I'd definitely recommend it. Review: Another solid offering from Elegoo - Elegoo makes good machines for good prices. I don't think that there's anything outstanding about this one, but it works well and enables the printing of larger objects. The only potential downside is that the machine required objects to be sliced into Elegoo's new format. What this format adds to the 3d printing space is unclear, as is why it was needed at all. It didn't take Lychee much time to release an update that enabled printing to the GOO format, so no issue there. (Ironically this is actually very convenient for me. Having files sliced for different printers in different formats allows me to instantly determine if I've already sliced a file for that printer. a GOO file? Good to go on the Mars 4.) I've got no issue recommending this printer. ## Features - 【7-Inch 9K Mono LCD】ELEGOO Mars 4 resin 3d printer boasts a 7-inch 9K mono LCD that boasts an impressive 8520x4320 resolution and 18μm XY resolution, enabling you to print crisp and intricate models every time with every detail of your model accurately rendered. - 【Large Build Volume】The 153.36×77.76×175 mm³/6.04×3.06×6.89 inch build volume provides you with enough space for daily creations without sacrificing printing accuracy. - 【COB Light Source】The Mars 4 3d resin printer uses a powerful COB light source that uniformly exposes the beam of 405nm wavelength across the entire LCD, ensuring that your prints are consistent and accurate. - 【Laser-Carved Build Plate】The build plate has a laser-carved surface that provides excellent adhesion and ensures that models stick to the build plate during printing to improve the printing success rate. - 【User-Friendly UI】The 3.5-inch touch screen comes with a model preview function and a real-time progress bar that allows you to monitor the printing process and make adjustments as needed. - If you have a problem with the product, please reach out to ELEGOO professional technical support team, we will respond within 24 business hours. - ELEGOO Mars 4 Resin Printer is suitable for 3d printing beginners.

My first order i was not able to print successfully. Turns out there was an issue with yhe screen. Seller sent me an advance replacement and have been printing flawlessly ever since. Seems like there my be issues with the screen so verify operation before disposing of the packaging. Overall the machine is exactly what I wanted for printing miniatures for TTRPG's. ## Frequently Bought Together - ELEGOO Mars 4 MSLA 3D Printer with 7" 9K Monochrome LCD, UV Resin Photocuring Printer, Multiple Print Modes, Printing Size of 6.04 x 3.06 x 6.89 inches - ELEGOO Mercury Plus 2.0 Wash and Cure Station V2 for Mars Photon S Photon Mono LCD SLA DLP 3D Printer Models - ELEGOO Water Washable 3D Printer Resin LCD UV-Curing Resin 405nm Standard Photopolymer Resin for Mars Saturn Jupiter MSLA DLP LCD 3D Printing 1000Gram Ceramic Grey --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/546641557-mars-4-msla-3d-printer-with-7-9k-monochrome-lcd](https://www.desertcart.be/products/546641557-mars-4-msla-3d-printer-with-7-9k-monochrome-lcd) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-23*
