Resin Printing Revolutionized: Elegoo Mars 5 Ultra Redefines Accessibility and Precision
Elegoo has long been a trailblazer in making 3D printing technology accessible to the masses, particularly with its line of budget-friendly resin printers that punch above their weight in terms of detail and performance. Over the years, the company has expanded its offerings, enhancing resolution, mechanics, and user-friendliness. From the groundbreaking Mars series that democratized high-quality resin printing to the larger Saturn models, Elegoo’s portfolio caters to both beginners and seasoned makers. Enter the Mars 5 Ultra ($349.99), a compact resin printer that combines a 9K-resolution monochrome LCD, cutting-edge light source, and a tilting resin vat designed to minimize peel forces and enhance print reliability. With features like automatic build-plate leveling, an onboard camera for live monitoring and time-lapse recording, and intuitive software, the Mars 5 Ultra is tailored for first-time resin users and budget-conscious hobbyists seeking modern capabilities without the need for a larger or pricier system like the Saturn 4 Ultra 16K. But here's where it gets controversial: while resin printing has traditionally been a messy and technically demanding process, the Mars 5 Ultra aims to simplify this, raising the question—can it truly bridge the gap between professional results and user-friendly operation? And this is the part most people miss: the printer’s innovative tilting resin tray, which reduces layer separation forces, could be a game-changer for print success rates, especially for intricate designs. However, the lack of certain convenience features, like a built-in resin heater or more robust drip management, might leave some users wishing for more. Is the Mars 5 Ultra the perfect entry point into resin printing, or does it fall short in addressing the inherent challenges of the medium? Let’s dive in and explore.
Unboxing and Setup: A Masterclass in Packaging and Preparation
Elegoo’s attention to detail is evident from the moment you receive the Mars 5 Ultra. The printer arrives in a sturdy outer carton with thick internal cushioning, ensuring it withstands the rigors of shipping. Inside, custom-cut foam braces the resin vat and build plate, preventing movement or damage during transit. This 'apocalypse packaging' has become a hallmark of Elegoo’s recent releases, setting a high standard for the industry. The accessory bundle is equally impressive, including gloves, scrapers, Allen keys, funnel filters, and a spare set of hardware for FEP film replacements. A USB flash drive preloaded with the Elegoo SatelLite slicer and sample models streamlines the setup process, while disposable face masks, a resin drip tray, and an external Wi-Fi antenna round out the package. The power adapter, though separately packaged, is compact and resembles a small laptop charger. Once assembled, the Mars 5 Ultra makes a striking visual impression with its compact proportions, clean lines, and tinted cover, giving it a modern, almost futuristic aesthetic. It’s clear that Elegoo understands the shift toward resin printers living on desks rather than in garages, and the Mars 5 Ultra reflects this design philosophy.
First Impressions and Setup: A Beginner’s Dream
Filling the resin tray is straightforward, thanks to molded-in pouring spouts and the included funnel, which screws onto Elegoo bottles for mess-free resin management. The tilting resin tray, a standout feature of the Mars 5 Ultra, addresses a common pain point in resin printing—layer separation. By tilting the tray from 0 degrees to -4 degrees before lifting, the printer reduces suction and stress on the print, leading to fewer failures and less wear on the FEP film. This mechanism is akin to peeling a label smoothly rather than pulling it straight up, resulting in a more controlled and intentional process. After filling the tray and plugging in the unit, a pre-flight checklist ensures all sensors are functioning correctly, providing peace of mind before starting a print. The overall user experience is reminiscent of entry-level FDM printers like the Bambu Lab A1 mini, with simplicity and ease of use at the forefront.
Test Prints and Performance: Precision Meets Practicality
The first test print, a standard rook model, showcased the Mars 5 Ultra’s capabilities. Despite the lack of an integrated resin heater (an optional add-on), the print emerged with clean details, well-defined staircases, and a crisp DNA chain. The onboard camera, while lacking a backlight, performed adequately in a well-lit room, though its effectiveness was limited when the build plate was submerged in resin. Suggestions for a 'stop and check' feature after a preset number of layers could enhance its utility. The build plate, laser-etched with microscopic grooves, ensured excellent adhesion, though Elegoo could improve by recommending an IPA clean before the first print. Calibration was streamlined by the printer’s ability to segment the build plate for exposure testing, allowing users to fine-tune settings efficiently. The 'Cones of Calibration' test confirmed an optimal exposure time of 1.8 seconds, with subsequent prints of the Siraya Tech Test Model and AmeraLabs Town Test Print demonstrating exceptional detail and accuracy. Miniature figurines, a staple for resin printers, were rendered with sharp features and no visible layer banding, even at a 0.018mm layer height. Larger models, like Marvel’s Wolverine, showcased the printer’s ability to handle intricate details with ease.
Software and Accessories: Enhancing the Experience
The Elegoo SatelLite slicer, included on the USB drive, offers a cleaner workflow compared to Chitubox, with intuitive controls and wireless file loading. The Mercury Plus V3.0 wash-and-cure station complemented the Mars 5 Ultra perfectly, providing a compact and efficient solution for post-processing. However, the printer’s lack of certain convenience features, such as a resin-bottle funnel or a handle for the cover, left room for improvement. Third-party designs, like an angle drip hanger and a magnetic drip tray, addressed these shortcomings, suggesting that Elegoo could enhance the user experience by including such accessories or print files in future iterations. Cleaning the auto-leveling build plate remained a challenge, but a 3D-printed cleaning tool helped mitigate this issue.
Final Thoughts: A Strong Contender with Room to Grow
The Elegoo Mars 5 Ultra earns its Editors' Choice award for budget resin models by delivering exceptional value, precision, and user-friendliness. Its innovative tilting resin tray and streamlined software make it an excellent choice for beginners, while its performance rivals that of more expensive machines. However, the absence of certain convenience features and the need for third-party accessories highlight areas for improvement. Is the Mars 5 Ultra the ultimate resin printer for hobbyists, or does it leave too much to be desired? Share your thoughts in the comments—do you think Elegoo has struck the right balance, or are there deal-breakers that hold it back from perfection?
