Meet the Sonic XL 4K Plus LCD 3D Printer

Sonic XL 4K Plus is equipped with an internal heater to keep a constant temperature printing environment. This heater warms up the entire printing area rather than only heating up the resin vat. Select 30°C or 35°C as your temperature settings & you’ll be able to produce high-quality 3D models at all times. This way, you can avoid print failures in low ambient temperatures.

The dental 3D printer also comes with a brand-new air purifier system that clears up resin fumes, and a specialized door buffer so you can have an enhanced 3D printing experience.
What’s in the Toolbox?
The toolbox contains essential tools for setting up the Sonic XL 4K Plus as well as tools to maintain your device after you’ve finished printing.
Please double-check to see whether everything is included in your toolbox. Make sure to understand how each tool is used before proceeding to the next step.
User Manual
The user manual contains essential information for users to set up their Sonic XL 4K Plus. This includes the introduction of functions and capabilities of the device, keynotes before printing, and a step-by-step tutorial for setting up the LCD 3D printer.
After-Sales Service & Warranty Certificate
Please view our Warranty Certificate to find your 3D printer’s serial number, in case the 3D printer (or parts of the 3D printer) are found to be damaged or not functioning properly. We also provide you with a QR code to our 3D printing tutorials and Warranty Policy.
Gloves
Please avoid direct contact with resin. This includes any part of your body or clothing. We suggest wearing PPE (Personal Protective Equipment) such as masks, goggles, and gloves while printing and using resin.
Scraper Set
The metal scraper is used for removing models from the building plate after printing. The plastic scraper is for cleaning the resin vat after printing or removing cured resin that is stuck on the FEP film or LCD screen.
DO NOT use the metal scraper to remove cured resin stuck on the FEP film.
