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

To start off, I’m a complete beginner to 3D printing.Back in high school, we did some basic 3D design and printing, but it wasn’t to the level that 3D printing is at now. The printers we had were older models that could only use certain filaments, and the technology wasn’t as advanced. I didn’t get into 3D printing seriously until recently, and I’m still learning along the way. So, you might be wondering: why am I talking about the Mars 5 Ultra when I’m a newbie? Well, I’ve been exploring 3D printing because I have a small business on eBay, and I wanted to add more product options to my listings.I started researching 3D printers online and quickly realized that there are so many options out there. I was particularly drawn to resin printing because it offers a level of detail that filament printers simply can’t match. If you’ve ever seen a resin print up close, you’ll know what I mean. The fine details are incredible. I also found that resin printers tend to have more predictable print times, which was a huge factor for me since I’m running a business and need consistency in my workflow. Of course, I’m not saying that resin printing is better than filament printing—it just has more of the features I was looking for.Another thing that’s worth mentioning is that I bought this printer with my own hard-earned money. I didn’t get it for free, and no one’s paying me to say nice things about it. So, everything I’m about to share in this video is my honest opinion, based on my own experience with this printer.So, why the Mars 5 Ultra?Let’s talk about the Mars 5 Ultra for a moment. I’m going to keep calling it the M5 Ultra because saying "Mars 5 Ultra" every time is just too much! M5 Ultra—much easier, right?Now, why did I pick the M5 Ultra?Well, to be completely transparent, marketing played a big role in my decision. I didn’t know much about 3D printers at the time, but I saw an ad that talked about all the amazing features, like the 8K screen, the tilting vat, and the laser-etched build plate. I thought, Wow, this looks like a high-tech printer that could handle everything I need and more. I also noticed it had a lot of positive reviews from other users, which definitely influenced my decision.One feature that really stood out to me was the self-zeroing build plate. If you’re new to 3D printing, one of the most annoying things can be manually leveling the print bed. It’s just a hassle, and if you don’t get it right, your prints can fail. The M5 Ultra takes care of that automatically, which is such a relief.Now let’s talk about the pros of the M5 UltraFirst of all, this printer is FAST. The tilting vat really helps with that. Instead of having to pull the print off the FEP after each layer is cured, the vat tilts and essentially peels the print off by itself. This minimizes the time spent on each layer and speeds up the whole printing process without compromising quality. I was honestly amazed by how fast the prints came out while still maintaining excellent detail.Another great thing about this printer is the camera feature.It has a built-in camera that lets you monitor the print remotely. This is fantastic, especially if you have a busy schedule or need to leave your printer unattended. Imagine being away from your printer and being able to check on your print from your Laptop—that level of convenience is something I really appreciate. It even supports time-lapse recording, which is perfect if you want to show off your print process to others or simply keep a record of your prints. Just be understand that if you want to get the most out of the camera arrange prints so short this are in so it does block the view.The M5 Ultra also comes with a 3-month subscription to Chitubox Pro, which is a huge bonus. If you’re not familiar with Chitubox, it’s a slicer software that makes it easy to prepare your 3D models for printing. The Pro version gives you access to more advanced features, like better support generation, advanced model manipulation, and more control over the print orientation. It’s definitely a tool I’m still learning to use, but I can already tell that it’s making my printing process a lot smoother.Let’s talk about the sensors and diagnosticsOne thing that stood out to me is the printer’s ability to run self-diagnostics. If something’s wrong, the M5 Ultra will let you know. It also has resin sensors that detect when you have too much resin or too little resin in the Another thing I like is how easy it is to adjust exposure times.The resin I’m using right now is Elegoo’s 8K resin. It’s a little picky when it comes to UV exposure, which means it sometimes requires longer curing times to properly stick to the build plate. the M5 Ultra made it really easy to tweak the exposure settings. I think it’s great when companies make things like this simple and accessible, especially for beginners like me.Now, let’s talk about the cons.No printer is perfect, and the M5 Ultra has a few things that could be improved.First, I’m not a fan of the lid.While it does a great job keeping fumes inside the print chamber and blocking UV light, it doesn’t have any hinges. So, whenever I need to open it, I have to take the whole lid off, which can be a bit annoying. And if you’re working in a small space like I am, it just takes up more room than I’d like.Another small issue I have is with the resin spout.The spout for pouring the resin is rounded instead of having a sharp edge. This might seem like a minor thing, but when you’re working with resin, you want to avoid spills and messes. A sharper spout would make it easier to pour the resin neatly and avoid making a mess.Last issues it the camera don’t get me wrong it is a great feature to have, but easy to block it with a large print, or the low res screen makes it hard something get whats going on. Expectionlly when most of us us heavy curtain to block out any sun light that can potentially ruin prints.Final ThoughtsSo, those are the main pros and cons of the M5 Ultra, at least from my experience so far. Overall, I’m really impressed with the printer. The print quality is fantastic, and the features, like the tilting vat, self-leveling build plate, and remote monitoring, make it incredibly user-friendly. I’m excited to keep printing with it and will definitely update this review after a few months to see how it holds up over time. Right now, I’m still in that “honeymoon phase,” but I’m looking forward to seeing how it performs once I get into the regular, day-to-day printing routine. I am very excited to try Elegoo other products.

I spent a lot of time researching 3D printers a few years ago and settled on the Elegoo Mars 2 and have not been disappointed. it has performed flawlessly. I design and produce products for the scuba industry and are available in 90% of the dive shops, Aquariums, Water, resorts and Theme Parks, in the US and World Wide. Occasionally I have to produce a limited run of a design or a prototype and the Mars 2 has been perfect.I decided I needed a bit more capacity with a slightly larger build plate and the Mars 3 seemed perfect for the task. Most of my manufacturing is sub contracted here in the US but the 3D printing is my personal project and is based in AZ. The printer arrived exceptionally well packed but there was a minor flaw in the touch screen. I stated using the printer and was not disappointed. From the very first print to this day, I have not experienced a single fail! For me a fail is lost time and money and I am often on a deadline with these small runs.The small flaw in the screen became bothersome and at the angle the printers are installed it became a problem for me, so I ordered a replacement and exactly the same problem.. I discovered it was an issue with the way they were packing the printer at the factory. The packaging applied pressure to the touch screen and it eventually created a bubble and moire pattern on the screen. Not a problem at some viewing angles but it was an issue for my setup.For me, the measure of a company is not based solely on the quality of their manufacturing nor their QC but the ability to respond to a customer service issues and resolve it effectively and in a timely manner. In this respect, Elegoo is EXCEPTIONAL! Rather than return the product, they immediately sent me a replacement screen, which is easily installed, and followed up to make sure all was OK. I have been absolutely impressed with Elegoo’s response and follow up, and they now have a customer for life. I also purchase their resins exclusively and I ascribe the combination of World Class resins in a World Class printer for the excellent results I consistently achieve with their products. When I need to print, I select the file and push print and I know that in a few hours those items will be ready to ship. I use Elegoo ABS Like exclusively in the Mars 3 and Elegoo Water Washable in the Mars 2 for prototyping.One final point, I installed a flex build plate prior to firing up the printer for the first time. I use both magnetic sheets (current sheets are 1/3 thinner than the one on my Mars 2 purchased a few years ago) one on top of the other for maximum adhesion, and have never had to touch the plate with a scraper. They remain pristine and produce a factory finish when a model is directly on the build plate.In summary, I give the Mars 3 a 5 star rating and Elgoo a 5 star +++.If you are looking for your first 3D printer or additional printers for commercial applications, look no further than Elegoo!
