New 3D Printing Dental Materials for Surgical Guides, Try-ins and Custom Impression Trays
Co-founder at AmeraLabs
After a long development and testing process, we have added three new dental resins to our range: CIT-25 for custom impression trays, SGR-28 for surgical guides, and TRY-23 for dental try-ins.
In this article, we will cover the key properties of these materials, explain how they can support your dental 3D printing workflow, and take you behind the scenes of how they were developed.
For us, this launch is not only about adding three more products to our portfolio. It is an important step in building materials, workflows, and providing support that dental labs and technicians can rely on in their everyday work.
Why We Developed These Resins for Dental Lab 3D Printing
Over the years, we have heard many of the same challenges from dental customers in different countries. For many labs, resin 3D printing is not always plug and play. Inconsistent results, unclear workflows, slow support, and material availability problems can quickly turn production into troubleshooting.
When something goes wrong, dental professionals need clear, practical help from people who understand both resin formulation and real 3D printing conditions. They also need materials that perform consistently, remain available, and fit into existing workflows without adding unnecessary complexity.
That’s why, while developing our new dental resins, our focus became broader than resin quality alone. The materials had to be accurate, reliable, and suitable for their intended applications, but they also had to fit into real existing dental workflows. From printability and post-processing to handling, sterilization, and support, each step had to be considered as part of the final result.
Because we develop and manufacture our resins in our own ISO-13485 certified facility in Europe, we can keep material development, production control, and customer support under one roof. This helps us maintain consistent quality and reliable supply, while allowing us to support dental labs with the product knowledge, processing guidance, and practical help they need.
Material Safety Came First
Developing dental resins for biocompatible prints meant working with a much stricter set of requirements than standard 3D printing materials. For our R&D team, this meant looking not only at the resin formulation itself, but also at the full workflow that turns the material into a finished medical device.
“For us, safety was the number one priority,” says Arminas, Polymer Engineer at AmeraLabs. “We had to understand exactly how each material would be used, what type of exposure it would have to the human body, and what could go wrong during the full process, from printing and washing to post-curing. Clear instructions for use were essential, because the final device has to be safe when every step is followed correctly.”
All three new resins are intended for the fabrication of biocompatible, short-term, removable dental appliances by 3D printing. Depending on the product, this contact time can vary. Custom impression trays may stay in the patient’s mouth for only minutes, while try-in materials may be used for longer periods.
“The biocompatibility and certification process was definitely one of the biggest challenges,” Arminas adds. “We had to implement a quality management system, prepare medical device documentation, and define the full process. Developing resins with specific mechanical properties and colors is familiar work for our team, but medical device materials add another level of responsibility.”
The result is three new dental resins that are CE Class I-marked, comply with ISO 10993-1, and are non-cytotoxic, non-sensitizing, and non-irritating when used according to AmeraLabs instructions.
CIT-25 Custom Impression Tray Resin
CIT-25 is our new material for 3D printing custom impression trays. It’s designed for custom edentulous, dentulous, and implant trays, including full-arch and sectional tray designs.
“With CIT-25, the goal was to create a resin that prints fast and accurately while remaining strong and reliable for chairside work,” says Vytautas, Polymer Engineer at AmeraLabs. “It can be printed at up to 200 µm layer height and still maintain high accuracy. When processed according to our instructions, it also does not inhibit silicone or other common dental impression materials, even without separator spray.”
After printing and curing, CIT-25 trims, grinds, and drills cleanly with standard dental tools, making chairside or lab-side adjustments easier. The printed trays resist cracking during handling and maintain their geometry over time.
SGR-28 Surgical Guide Resin
SGR-28 was developed for tooth-supported and mucosa-supported dental surgical guides. It can be used for freehand guidance, pilot-drill guides, single-implant cases, full-arch and full-mouth reconstruction cases, and both partially and fully guided surgery. The material is also suitable for complex stackable “puzzle-type” immediate loading guides.
“For SGR-28, we focused on dimensional stability, accuracy, and strength,” says Vytautas. “The guide must stay stable during handling and use, and translucency also helps with visual verification of proper seating. We tested multiple colors to find the best balance of visibility and performance.”
With a Shore D hardness of 85 and high flexural strength, SGR-28 helps 3D printed surgical guides remain rigid and stable, supporting accurate drill guidance during surgery.
The resin accepts both polymer and metal guide sleeves, giving dental professionals flexibility across different guided surgery workflows. SGR-28 is also autoclavable for clinical use when AmeraLabs post-processing instructions are followed.
TRY-23 Dental Try-In Resin
TRY-23 is a 3D printing resin for biocompatible dental try-ins. It can also be used for splint fit checks, occlusal verification, tooth setup verification, and digital mock-ups.
“With TRY-23, we focused on the properties that matter in try-in workflows: natural tooth-like translucency, a selection of dental shades, high accuracy, and dimensional stability over time,” says Tadas, Polymer Engineer at AmeraLabs. “The material is strong enough to withstand standard handling workflows, while low water absorption helps it maintain accuracy even after an extended period of time.”
The material has a flexural modulus above 2 GPa, giving it the rigidity needed to hold its shape during fit verification. Its very low water absorption helps preserve dimensional accuracy through lab-to-clinic transit, chairside adjustment, and rescanning workflows.
TRY-23 is available in four tooth shades: A1, A2, B1, and B2. It is also easy to cut, stain, and polish, giving dental technicians more flexibility when adjustments or presentation details matter.
Open 3D Printing System Compatibility
We know that dental labs and technicians work with different printer setups. That is why our dental resins are developed for open 3D printing systems.
CIT-25, SGR-28, and TRY-23 cure with 385 nm and 405 nm light sources, offering broad compatibility with LCD/LED and DLP printers from manufacturers such as Asiga, Formlabs, Phrozen, Anycubic, Elegoo, Prusa, and similar systems.
To make setup easier, we provide initial printing settings and detailed processing instructions for supported workflows. These give you a reliable starting point when introducing a new material into your lab.
Consistent Quality, Supply, and Expert Support Provided by a 3D Printing Resin Manufacturer
We understand that for dental labs, the material itself is only one part of the decision. A good resin also needs to come with consistent quality, reliable availability, and support that actually helps when questions or problems appear.
We run quality tests on every resin batch we produce, helping us maintain consistent performance batch after batch. We have also refined our manufacturing processes to support a stable product supply, keep regular stock on hand, and continue expanding our network of trusted resellers to make our resins more accessible.
We also understand how important timely support is. Our team provides expert, practical guidance to help customers choose the right materials, test them effectively, and integrate them into everyday dental 3D printing workflows smoothly and with confidence.
When customers come to us with questions, we take the time to understand the situation, look at the workflow, and help them find the best way forward. Because your success is our success.
A Step Forward for AmeraLabs Dental 3D Printing Materials
