4 sources3 derived$299.99as of Aug 1

The Elegoo Mars 5 Ultra stands out as a feature-rich resin printer with a 9K monochrome display and 18 µm XY resolution, making it one of the most capable consumer models Elegoo has produced. Reviewers praised its tilt release mechanism and AI camera, though the latter was deemed ineffective due to poor positioning. The printer lacks an air filter and chamber heating, which may disappoint users seeking advanced environmental controls. While it offers Wi-Fi connectivity and a user-friendly interface, the placement of ports and the camera's functionality are notable drawbacks. This printer is ideal for users wanting high-resolution prints with smart features but may not suit those needing advanced environmental controls.

Strengths
  • Features a 9K monochrome display with 18 x 18 µm XY resolution for high-detail prints
  • Includes a tilt release mechanism that reduces print stress and improves adhesion
  • Equipped with an AI camera for real-time monitoring and time-lapse photos
Watch-outs
  • AI camera is poorly positioned and ineffective for monitoring prints
  • No air filter or chamber heating included
  • Power switch and USB port located on the right side rather than front
Phrozen Sonic Mini 8K S
Ranked #6 in Best Resin 3d Printers
Phrozen Sonic Mini 8K S
4 sources2 derived$299.99as of Aug 1

Tom's Hardware reviewed the Phrozen Sonic Mini 8K S as an affordable upgrade to their previous model, noting it maintains the same high screen resolution and printing volume of 16.5x7.2x17 cm. YouTube reviewer Ross praised it for being free of the technical issues that plagued his original Sonic Mini 8K, calling it a significant achievement given the price point. However, the printer is 1 cm shorter in height than its predecessor. This model targets budget-conscious users seeking premium print quality without the higher price tag of the original.

Strengths
  • Setup runs clean out of the box, with no calibration or hardware snags
  • Maintains same screen resolution and printing volume as original Sonic Mini 8K
  • Offered at entry-level prices compared to previous model
Watch-outs
  • Slightly shorter height in printing volume (1 cm less than original)
  • May have limited long-term reliability data compared to established models

How they stack up

Elegoo Mars 5 Ultra

The Elegoo Mars 5 Ultra boasts a 9K monochrome display and tilt release mechanism, outperforming the Phrozen Sonic Mini 8K S in resolution and functionality. However, it falls short of the Anycubic Photon P1 in terms of thermal control and dual-material printing capabilities. Its AI camera is poorly positioned compared to the Elegoo Saturn 4 Ultra's network connectivity features.

Phrozen Sonic Mini 8K S

The Phrozen Sonic Mini 8K S provides high-quality prints at an entry-level price, outperforming the Elegoo Saturn 4 Ultra in resolution and reliability. However, it's slightly shorter in height compared to the Elegoo Mars 5 Ultra and lacks the heated chamber of the Uniformation GK Three Ultra. It also doesn't feature the AI camera or Wi-Fi capabilities found in the Elegoo Mars 5 Ultra or Elegoo Saturn 4 Ultra.
