Print quality

The Phrozen Sonic XL 4K Plus is a professional LCD 3D printer that can print layers at a minimum height of 10 microns, with an XY positioning accuracy of 52 µm. This way, you can produce objects with extremely smooth exterior surfaces, clean edges, and fine detailing.

To ensure consistent and stable model formations, the printer is equipped with a constant heater to maintain chamber temperature at the optimal 30 °C. The upgraded heating system aims for better heat distribution, mitigating any overheating damage and boosting print success rates. Due to the reliable door buffer and air filtration system, the whole workflow becomes even more effective and comfortable for the user.



The Phrozen Sonic XL 4K Plus offers a variety of materials to choose from. It is compatible with both self-developed and 3rd party 405 nm UV resins, including special dental ones. Thanks to its open material system, the printer gives the user a broad material choice for a wider number of professional tasks.
