Lithuania-based 3D printing resin manufacturer AmeraLabs has expanded its dental materials portfolio with three new CE Class I-marked resins for common dental laboratory workflows.
The new materials include CIT-25 for custom impression trays, SGR-28 for surgical guides and TRY-23 for dental try-in applications. AmeraLabs has developed each formulation around the mechanical, processing and handling requirements of its intended application.
According to AmeraLabs Co-Founder Andrius Darulis, the launch expands the company’s dental range with materials designed around accuracy and reliability for routine lab applications.
Application-specific resins for dental labs
TRY-23 is designed for try-in dentures, diagnostic dentures and implant-supported denture try-ins, as well as fit, occlusal and tooth setup verification. With a flexural modulus above 2 GPa and low water absorption, the material is designed to maintain rigidity and dimensional accuracy during adjustment and rescanning. It is available in A1, A2, B1 and B2 tooth shades.
SGR-28 targets tooth- and mucosa-supported surgical guides for procedures ranging from single implants to full-arch and full-mouth reconstruction. A Shore D hardness of 85 and high flexural strength are intended to maintain guide stability during drilling. The translucent resin accepts polymer and metal guide sleeves and can be autoclaved when processed according to AmeraLabs’ instructions.
CIT-25 is intended for custom edentulous, dentulous and implant impression trays. It can be printed at layer heights of up to 200 µm and is compatible with silicone, alginate and other common impression materials. AmeraLabs says the resin does not require separator spray when processed according to its instructions and can be trimmed, ground and drilled using standard dental tools.
Open-system compatibility for dental 3D printing
All three resins cure using 385 nm and 405 nm light sources, giving them compatibility with a range of LCD/LED and DLP dental 3D printers.
AmeraLabs lists systems from Asiga, Formlabs, Phrozen, Anycubic, Elegoo and Prusa among the compatible platforms, alongside other printers using similar light sources. The company also provides initial print settings and processing instructions to help labs integrate the materials into existing workflows.
According to AmeraLabs, CIT-25, SGR-28 and TRY-23 are CE Class I-marked and comply with ISO 10993-1. The company states that the materials are non-cytotoxic, non-sensitizing and non-irritating when used according to its instructions.
The formulations are also free from TPO, THFA, MMA, BPA and phthalates. AmeraLabs develops and manufactures its resins at its ISO 13485-certified facility in Europe, where the company says each batch undergoes quality testing. CIT-25, SGR-28 and TRY-23 are now available through the AmeraLabs online shop and its authorized resellers.
Application-specific materials meet open dental workflows
Dental 3D printing vendors are increasingly developing application-specific materials as part of integrated hardware and software workflows. Stratasys, for example, combines its J5 DentaJet with materials including CE-marked TrueDent resin, while 3D Systems has taken a similar approach with its NextDent platform and dedicated denture materials.
Other manufacturers are taking this integration further. Novenda Technologies’ LD100 operates exclusively with the company’s own materials, while Axtra3D has expanded its portfolio with dedicated resins for models, splints, dentures, and crown-and-bridge applications.
