The Phrozen Sonic Mini 4K is a compact MSLA 3D‑printer engineered for high detail resin production with a 4K monochrome LCD and a stable 405 nm optical engine. Its 35 micron XY resolution, fast exposure performance and uniform light distribution make it suitable for engineering prototypes, dental models, miniatures and general purpose resin applications. The reinforced Z‑axis and high transmittance LCD ensure consistent layer stacking and predictable curing behavior across the full build area.

High precision MSLA performance
The Sonic Mini 4K uses a 3840 × 2160 pixel monochrome LCD with high UV transmittance, enabling shorter exposure times and improved durability compared to earlier RGB‑LCD printers. The optical engine provides uniform irradiance across the build area which supports accurate dimensional reproduction and sharp surface detail. Combined with a rigid frame and stable mechanics, the system delivers reliable performance with a wide range of 405 nm compatible resins.

Resin 3D‑printing workflow
The resin 3D‑printing workflow on the Sonic Mini 4K is defined by its fast exposure performance, uniform optical output and stable Z‑axis motion which together support predictable layer bonding, consistent curing behavior and reliable results across a wide range of 405 nm materials.
Exposure performance
The monochrome LCD enables short exposure times which improves throughput and reduces heat buildup during long prints.
Layer consistency
Uniform irradiance and stable mechanics support predictable layer bonding and reduce the risk of dimensional drift.
Material compatibility
Most 405 nm resins perform well on the Sonic Mini 4K. Engineering grade materials may require longer exposure values to maintain accuracy.
