Elegoo Mars 5 Ultra
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
