Overview

The Pro 2 Duo Kit enables dual-resin printing by allowing two materials or two shades to be printed in a single job. This capability increases production efficiency, reduces material changeovers, and supports parallel workflows for both clinical offices and dental laboratories. 

Why the Duo Kit Matters

For Dental Laboratories

• Increase throughput with parallel production
• Eliminate time lost to resin changeovers
• Support multi-case and multi-indication workflows without setup delays

Use cases include combinations such as:

• Denture base and denture teeth
• Smile design and provisional
• Models and crowns

For Dental Practices

• Produce multiple appliances or dentures in a single print cycle
• Reduce patient wait times
• Improve chairside efficiency and expand in-office services
   

Key Benefits of Duo Kit Printing

Dual-resin capability – Print two resin types or shades simultaneously.

Continuous production – Avoid stopping to swap tanks or materials.

Simple integration – Install quickly with minimal training; automatic calibration simplifies setup.
 

What the Duo Kit Includes

The Duo Kit consists of:

• Duo Kit build platform
• Resin tank adapter
• Two individual Duo resin tanks
• Washing adapter for post-processing

These components replace the standard platform and tank when dual-material printing is required.
 

Installation and First-Time Calibration

When the Duo Kit is installed for the first time, Pro 2 automatically performs a calibration cycle.

Steps:

1. Install the Duo Kit platform, tank adapter, and tanks.
2. When prompted on the touchscreen, remove the platform, tanks, and adapter.
3. Close the UV protective hood.
4. The build arm will lower fully, then rise to the top.
5. The printer will confirm that calibration is complete.

This automatic calibration only needs to be performed once during the initial Duo Kit installation. Subsequent installs do not require repeating this process unless prompted by the device.
 

How to Use the Duo Kit for Printing

1. Prepare the Print Job

Dual-material printing begins in Print Setup.

• Approve your design files in SprintRay Cloud Design or import STL files.
• Select the indications you want to print.
• Choose “New Print Job” for each model when prompted.

2. Enable Duo Mode

In Print Setup:

• Navigate to the Indications panel on the right.
• Select Duo Mode.
• Assign indications to Tank 1 (left) and Tank 2 (right).

Any design previously approved through Cloud Design is automatically backed up in Cloud Drive and can be added through the Cloud Drive button. Locally designed models can be added via drag-and-drop.

3. Review Setup and Send to Printer

Confirm:

• Correct resin assigned to each tank
• Correct material placement (Tank 1 left, Tank 2 right)
• Proper model orientation and layout

Once verified, send the job to the printer.
 

Washing Duo Kit Prints

When washing parts printed with the Duo Kit:

• Always use the included Duo washing adapter.
• This prevents accidental contact between the parts and internal components of SprintRay washing devices.
