Technical Specifications & What They Mean
Understanding specifications helps predict real-world performance. The Mars 2 Pro packs impressive technology into its compact frame, but numbers only tell part of the story.
Build Volume & Print Size Reality
The 129 x 80 x 160mm build volume initially seems limiting compared to CoreXY 3D printers. However, this size perfectly suits its target applications. You can print multiple miniatures simultaneously or create jewelry pieces without wasting resin.
Most users find the vertical height of 160mm more than adequate. Larger models can be split into sections using ChituBox’s cutting tools, though this adds post-processing complexity.
Understanding 2K Mono LCD Technology
The 1620 x 2560 pixel monochrome LCD represents a massive upgrade from older RGB screens. Monochrome LCDs allow more UV light transmission, reducing exposure times from 8-9 seconds to just 2 seconds per layer.
This technology translates to 50-micron XY resolution across the build area. While 4K printers offer marginally better detail, the difference remains invisible to the naked eye for most applications.
Speed Specifications Decoded
Print speeds of 30-50mm per hour depend entirely on layer height settings. Using 0.05mm layers (standard quality), expect around 40mm/hour vertical growth. This means a 40mm tall miniature prints in approximately one hour.
The 2-second exposure time remains consistent regardless of layer complexity. Unlike FDM printers, resin printers cure entire layers simultaneously, making them ideal for batch production.
