Enhance Your Production of Digital Models & Dental Prostheses
Phrozen has been elevating the LCD 3D printing technology to a whole new level and is now applying it in the dental field.
With a larger printing volume and impeccable precision, Sonic XL 4K PLUS ensures excellent printing quality each time.
On top of that, Sonic XL 4K PLUS features more robust operation to withstand the demands of large batch high-precision dental 3D printing.
Add-On Heater for Stable Printing Environment
Equipped with a constant heater to maintain printing temperature at the optimal 30°C to ensure stable model formations. A heating system upgrade aims for better heat distribution, mitigating any overheating damage and boosting print success rates.
Boost Efficiency With a Larger Building Plate
With a 9.3" LCD panel, Sonic XL 4K PLUS provides a larger building plate to increase printing capacity and efficiency.
Phrozen DS Slicer
Comes bundled with the Phrozen Dental Synergy (DS) Slicer,
Sonic XL 4K PLUS automates most of the file-prepping process and
further simplifies in-clinic 3D printing workflow.
Improve the Dental Printing Process
Add-on air purifier to reduce odor and ensure users' safety.
Clinical Evidence
Treating Severe Scissor Bite with a Digital Orthodontic Workflow with XL 4K Plus
A clinical case demonstrating how a digital orthodontic workflow—combining guided miniscrew placement, clear aligners, and dental 3D printing—can be used to treat severe scissor bite.
Proven in Practice
It’s a workhorse for models.
Very stable print quality and one of the best dental slicers in this price range.
I’ve used the XL series for several years and it has worked great for dental models.
DS Slicer that comes with Phrozen Dental printers is actually really good.
