Experience ultra-precise 3D printing with Elegoo Mars 4 Ultra. It features a 7-inch 9K mono LCD with a resolution of 8520 × 4320 and 18 μm XY resolution, enabling you to print models with exceptional details and sharp edges.

9K_Accuracy_with_Stunning_Detail-1.jpg

up to 150mm/h Printing Speed

Print 3x faster without losing detail. Mars 4 Ultra achieves speeds up to 150 mm/h, delivering high-speed precision for flawless, intricate prints every time.

9K_Accuracy_with_Stunning_Detail-2.jpg

High-Speed Wi-Fi Transfer

The brand new Linux OS with built-in 4 GB ROM supports Wi-Fi transfer, with a transmission speed of 6–10 Mbps. Plus, it is compatible with both 2.4G and 5G networks, making file transfer a breeze from your computer or mobile device.

The detachable Wifi antenna is conveniently placed on the side of the printer's Z-axis, making it easy to connect to your network.

High-Speed_Wifi_Transfer.jpg

COB Light Source + Fresnel Collimating Lens

With 92% light uniformity and precise beam control under 5°, the 405 nm COB light source and Fresnel lens work in perfect harmony to deliver flawless layers for smooth, consistent prints.

COB_Light_Source_Fresnel_Collimating_Lens.jpg

Stable Printing Performance

The Z-axis adopts a linear guide rail structure with an accuracy of 0.02 mm, ensuring precise and stable movement to help eliminate riffles on final prints and produce smooth and delicate surfaces on your models.

The 4-point leveling system with four clockwise-tightening screws is design to eliminate the need for repeated leveling after one-time leveling, saving you time and effort.

The build plate has a laser-engraved
surface to enhance adhesion during the printing process, even when printing large models.

Stable_Printing_Performance.jpg

Improved Printing Experience

There is a large cooling fan and heat-conducting copper tubes positioned next to the COB light source for rapid heat dissipation. This feature not only enhances the printer's performance but also extends its service life.

The upgraded air purifier has a protective plastic case to safeguard the built-in activated carbon filter during transportation and effectively remove resin odor during printing.

The printer comes with Voxeldance Tango Slicer, which offers both static mode and dynamic mode (including smooth and high-speed mode) to improve your printing efficiency. The open-sourced GOO slice file format is compatible with third-party slicing software, such as CHITUBOX and Lychee Slicer.

Improved_Printing_Experience.jpg
Leak-proof_design.jpg

The printer's mid-plate is designed with a raised step to keep the resin from flowing inside the printer, which protects the printer's internal components from damage and ensures a clean workspace.
Screw_end_caps_for_build_plate_screws.jpg

The build platform screws have screw end caps for easier cleaning, which saves your time and effort during post-processing and maintenance.
Adjustable_foot_pads.jpg

The adjustable foot pads for improved stability ensure that the printer remains stable on uneven surfaces.

Printers do not last

So i had two Mars 4 Ultras not even two years old now suddenly stop working at one right after the other in the exact same ways. I replaced the one doe to the vat screw getting so stuck i could not remove it and the printers was useless. I got another one brand new and suddenly the other printer is now having the same problem. shooting down randomly in the middle of printing, the print bed not rising up. And i see that the new mars 4 ultra has a version on it that is not available to download. The new one has V1.2.5 can the most resent you can get is v1.2.4. seems like they want old ones to die. If this review is even posted as the first review i posted that was lowing than a 4 star was never posted to this site. Seems like that are trying to hide the reviews that tell people how their printers really work.

LCD Screen Too Fragile

It's a great printer for the price, But be warned that after less than 200 hours of printing runtime, my LCD screen died, and they refuse to replace it because their warranty is only 3-months. I'm glad that I have the option to buy and replace my own screen... but a 3-month warranty is ridiculous, and the cost of the screen is almost 1/3 of the total price of the unit. Would recommend a company with a nicer warranty or a more reliable LCD screen.

Very nice!

Not as fast as I was hoping (never is) but the detail is amazing once you get the settings dialed in.

Super Reliable

I picked up another Mars 4 Ultra to add to my print farm because they're super reliable. They just work, period. I'd rather have a small fleet of these than the newer Mars 4 because of how much control I have over how the M4U prints (speed, etc). These are great for small orders or reprinting parts that failed on my larger Saturn 4U printers.

Fast Delivery, Great Price and Works Great

The delivery was very fast with tracking, I got it on sale for a very good price, the unit took less than an hour to set up and it worked perfect right out of the box, no additions needed, great support team for any help, print speed is extremely fast about an inch in height per hour regardless of how much is on the plate!

Amazing printer

This is my first printer. I bought it to save money on buying minis. It's printed far better minis than I ever could find when trying to buy already printed ones!

Great First SLA

My first SLA printer and it's been great. If I had one complaint 1) I wish it had a heater or I wish the cover was bigger so you could fit a heater under it easily

Great entry to Resin Printing

I've never used a resin printer before, and this was a great entry level machine. It's high quality and so far I have had very few failures, all of which have been my own mistakes. Id recommend a Mars size printer for anyone who wants to enter the world of resin.

Great Product!

After an initial learning curve, my printer was up and running! Well worth it. Good quality prints and fast!

My First Printer

Came well packed, easy to setup w included guide. First few prints went well using the default settings in the printer and Chitubox.
FEP film seems a bit easy to damage, the included plastic scraper left fine scuff lines on the FEP when I tried cleaning it using 'Vat Clean' mode.
Printer seems good quality overall, so far pleased w my purchase.

Excellent print quality

I love the quality of the prints I get from this machine. It holds details very true to the model. I love that it has wifi capability but I dropped it a star due to the chitubox manager only being compatible with the Saturn machines.

Disappointed

Buyer be ware! If you happen to get a fully functional printer great. If you get one that has issues good luck. Please read the following to understand what you may be in for:

This may be a little long winded, but I feel it is necessary to explain in depth what I have dealt with the last 11 months. Let me start off by saying that this was my first 3D printer and I chose it after a lot of time researching printers and their manufacturers. I chose ELEGOO, in part because the mars 4 ultra offered most of what I was looking for in my first printer. It appeared that it would take out a lot of the headaches and learning curves that other printers struggled to do. The other reason for choosing ELEGOO was because I bought into their 1- year warranty and lifetime support offerings…

I purchased this printer 11/17/23 and I was incredibly excited upon receiving it and looked forward to getting it set up and start printing. However, things did not work out as I had hoped. I went through a lot of frustration trying to print right out of the box. I spent countless hours researching issues and troubleshooting them with no great change in my print results. I tried everything I came across with no success. Re leveling the build plate, changing the FEP ( I even ordered a whole new vat incase I was not changing the FEP correctly), cleaning the screen, countless validation prints trying to hone in the correct parameters, using a heater in case my temp was to low, trying various different resins, etc. After months of this I assumed I was still doing something wrong and that it’s just the difficulties of learning how to print correctly.

Fast forward to April 2024 and I had decided that I would pack the printer up and try to sell it. I was looking to order the new Saturn 4 ultra as it looked like it might be the printer to solve all of the issues I was having with my M4 Ultra. I had no luck selling the printer however. So, in September of 2024 I decided to unbox the printer and give it another go. Surely this time I would be able to figure it out and get some consistently successful results. I couldn’t have been more wrong. After going through more troubleshooting and validation tests, I decided to contact the manufacturer of my resin to see if they had any suggestions. They did have a few suggestions and after implementing those I was still encountering more consistent fails than successes. At this point the resin manufacturer recommend I contact ELEGOO’s tech support.

I did just that on 10/23/24. After 15+ correspondences back and forth with tech support I still have no resolution. I have performed every task that they have requested. All of which were things I have already done my self on multiple occasions, but I did them anyway. ELEGOO, you have seriously dropped the ball on this one and have lost a customer. I am beyond frustrated. I am tired of getting the run around from your worthless tech support. I am stuck with a $300 printer that the only thing it is good for is waisting time and resin. This whole thing has been incredibly frustrating and discouraging. Not to mention a huge waist of money. Not only am I stuck with the $300 useless printer, but I have spent hundreds of dollars on resin, FEP, detergent, IPA, and other consumables trying to have successful prints with almost nothing to show for it. What I thought was all error on my part over the last 11 months has clearly turned out to be a faulty printer. There is no other explanation at this point. It doesn’t matter what resin, settings, or files I use. It will fail 95%-100% of the time. I am thoroughly disappointed in this machine and in ELEGOO’s after sales service, or lack there of in my experience. Not only have I had no luck with tech support, but I filed a warranty claim with no results as well…

New to resin printing

After reading reviews I decided to purchase the Mars 4 ultra. The setup was easy and the information given on the USB drive helped get everything going. Had to adjust the bed several times but got it as level as can be. Started printing many of my projects and learned alot from using this printer. I would recommend this print to anyone new to resin printing as it was easy to get started.
Thank you for a great product.

Best one Yet

I have been using Elegoo for Years and each new printer keeps getting better, faster, and easier to use. This has the quickest & most accurate printing times and the quality is highly detailed. The Mars 4 Ultra the ideal choice for smaller and more detailed pieces. I have been using it specifically for jewelry design and I wouldn't want any other 3D printer for this type of work. I highly recommend.

A Little Disappointed

I bought a used one and it arrived with a punctured release film and with the tank still holding some resin. After replacing the film and cleaning the whole printer, I have been unable to get a successful print at the time of writing this, but I’m still hopeful that I can as I believe it’s more of a problem with setup than with the printer itself. The printer seems to work as advertised, but I was rather disappointed with the quality and condition of replaceable parts, which seems to me like elegoo did not check or test the printer after they got it back from the original owner.

High quality and easy to use

As a new owner of the mars 4 ultra, I am extremely excited to see the level of detail this machine can produce. I have been doing calibration tests for the last day using elegoo 8k resin and have got insane quality on several tests. Thank you, elegoo. The product is amazing, and I look forward to getting my Saturn 4 ultra when pre-orders ship.

Loving this 3D Printer

Moved from the Mars 4 to the Ultra due to issues with the one I purchased through Amazon. I have to say I love this printer. Easy to setup and use. Had my first print in hand in less than two hrs from opening it up. Things are now dialed in and I’m ready to start making videos and tutorials on this amazing machine.

Minha impressora está desligando sozinha quando inicia as impressões, ja troquei o cabo de força, mas o problema persiste, conversei com quem entende do assunto e eles afirmaram ser placa mãe da impressora, porém não encontramos ela pra venda, como prosseguimos? Um ano e meio de uso
