New Precision Model Resin for 3D Printing Restorative Models With Industry-Leading Accuracy and Precision

Restorative models printed in tan resin

When it comes to dental 3D printing, the material you choose can make all the difference. Formlabs Dental’s Precision Model Resin is designed to deliver exceptional accuracy and precision, making it ideal for restorative models that demand high-quality results. With over 99% of the printed surface within 100 μm of the digital model, this resin sets a new standard in digital dentistry.

With more than 15 million dental parts printed using our range of 15+ dental-specific resins, we continue to push the boundaries of what’s possible. By working closely with the new Form 4B hardware, we’ve developed materials that offer faster print speeds, improved accuracy, and better mechanical performance. This integrated approach ensures that every part meets the highest standards of quality and reliability.

Precision Model Resin

Precision Model Resin is the next generation of model resin, engineered to take full advantage of the Form 4B platform. It offers faster print speeds, greater accuracy, and improved aesthetics—making it ideal for restorative models that require both visual clarity and structural integrity.

This resin is perfect for:

  • Restorative models
  • Crown fit test models
  • Implant models
  • Removable die models

Formlabs’ materials team has worked closely with dental professionals to address real-world challenges. One key improvement is the increased opacity of Precision Model Resin, which helps clearly define margin lines. Dr. Christopher Baer from Baer Dental says, “The color looks great—especially for crowns. The team at Formlabs really nailed it.”

Thanks to the Form 4B’s advanced hardware, prints are up to three times faster than previous formulations. At a 50 μm layer thickness, eight restorative models can be printed in just 90 minutes, with a cost per part ranging from $2 to $4.

Precise and Accurate

Using Precision Model Resin on the Form 4B, restorative models have 99.7% of their surface area within 100 μm of the CAD model, and 95% within 50 μm. This level of consistency across printers and batches ensures reliable, repeatable results for any dental practice.

Create restorative models with over 99% of their printed surface area within 100 μm of the design parameters.

Compared to other leading competitors, Precision Model Resin delivers superior accuracy at all tolerance levels. Here's a quick comparison:

Production-Optimized Workflow

Speed improvements aren’t just about print time—they also enhance post-processing, resulting in a faster overall workflow.

Scan and Design

Once the patient’s dentition is scanned and the model is designed in your dental CAD software, import the digital models into PreForm Dental as an STL or OBJ file.

In PreForm, orient parts directly on the build platform. For best results, manually orient and support the dies.

Once parts are oriented, upload the print and prepare the printer by inserting a resin tank, Precision Model Resin cartridge, and a clean build platform.

Post-Process

Remove parts from the build platform using a part removal tool if chamfer features were added, or flush cutters if not. Wash the parts in 99% IPA for five minutes, then cure them in the Form Cure for five minutes at 35°C or use Fast Cure for 30 seconds at Light Intensity 2 for optimal properties.

Improved Material Properties

Precision Model Resin is tougher, stronger, and more impact-resistant than its predecessor, Model Resin. This means post-cured prints are less likely to break, especially when pressing in dies or implant analogs.

Case Study at Hybridge Implants

Hybridge Implants is a nationwide provider of full-mouth implant-supported prosthetics. Their process relies on precise 3D printed models, where metal components must be accurately screwed in. The accuracy and strength of these models are critical for success.

“We've been amazed by the Precision Model Resin and how fast it prints. Previously, we had issues with threads not holding, but that’s no longer a problem.”

Shawn Simpson, CAD/CAM technician, Hybridge Implants

Before switching to Precision Model Resin, Hybridge used two different resins—one for the metal department and another for assembly. Now, they can print one model that serves both teams, saving time and resources.

Christina Rivet, Vice President of Lab at Hybridge, said, “The print speed is amazing. The new material is strong, fast, and offers many options for our prints.” The combination of accuracy, toughness, and ease of cleaning makes Precision Model Resin a game-changer for their workflow.
