Split file 3D printed partial denture exocad design

Introduction

This tutorial provides a step-by-step guide on how to design a split file for a 3D printed partial denture using Exocad. It focuses on leveraging the Sprintray retainer material for optimal results. By following this guide, dental professionals can enhance their printing process and create high-quality dental prosthetics.

Step 1: Setting Up Exocad

• Open Exocad and create a new project.
• Import the digital impression or scan of the patient’s mouth.
• Ensure the scan data is properly aligned and all relevant anatomy is visible.

Step 2: Designing the Partial Denture Framework

• Use the "Partial Framework" tool within Exocad.
• Select the teeth that will be included in the design.

Adjust the design parameters according to the patient’s specifications, such as

• Occlusal support
• Retention features
• Use the design tools to refine the framework, ensuring all parts fit comfortably.

Step 3: Splitting the File

• Navigate to the "File" menu and select the option to split the model.
• Choose the appropriate splitting method based on your printer’s capabilities.
• Create two separate parts of the denture to optimize printing with Sprintray material.

Step 4: Exporting the Split Files

• Save each split part separately in STL format.
• Ensure the file names are clear to avoid confusion during printing.
• Double-check the orientation of each part in the export settings.

Step 5: Preparing for Printing

• Import the STL files into your slicing software.

Configure the print settings specific to the Sprintray material, including

• Layer height
• Print speed
• Material temperature settings
• Preview the print to ensure everything is correctly aligned.

Step 6: Printing the Partial Denture

• Load the Sprintray material into the printer.
• Start the printing process and monitor it for any issues.
• Once printing is complete, carefully remove the parts from the printer.

Step 7: Post-Processing the Printed Parts

• Clean the printed parts according to the manufacturer’s guidelines.
• Cure the parts using the recommended light exposure time for the Sprintray material.
• Assemble the parts of the denture carefully, ensuring a proper fit.

Conclusion

In this tutorial, you learned how to design a split file for a 3D printed partial denture using Exocad and how to effectively use Sprintray retainer material. By following these steps, you can improve the efficiency and quality of your dental prosthetics. Next, consider experimenting with different designs or materials to further enhance your practice. Happy printing!
