Print Quality & Real-World Testing
Resin printing excels at detail, and the Mars 4 Ultra doesn’t disappoint:
- Miniature Detail Test: 9.5/10 - Fine hair strands, fabric folds, and tiny text all render beautifully
- Print Success Rate: 90% - Reliable hollowing and support generation in Lychee Slicer

Post-Processing Requirements
Resin printing requires additional steps:

- UV Cure - 15-30 minutes under UV light
- Support Removal - Careful removal of support structures
Safety Notes
Always use resin printers in a well-ventilated area and wear appropriate PPE (gloves, mask). The built-in air purifier helps but isn’t a substitute for proper ventilation.
