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 materials include CIT-25 for custom impression trays, SGR-28 for surgical guides and TRY-23 for dental try-in applications. Each formulation has been developed around the mechanical, processing and handling requirements of its intended use.
According to AmeraLabs co-founder Andrius Darulis, the launch expands the company’s dental range with materials focused on accuracy and reliability for routine laboratory applications.
Application-specific resins for dental laboratories
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 intended to maintain rigidity and dimensional accuracy during adjustment and rescanning. It is available in A1, A2, B1 and B2 tooth shades.
SGR-28 is intended for tooth- and mucosa-supported surgical guides, covering procedures from single implants to full-arch and full-mouth reconstruction. A Shore D hardness of 85 and high flexural strength are designed to maintain guide stability during drilling. The translucent resin accommodates 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. According to AmeraLabs, 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, making them compatible 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 laboratories 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-sensitising 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 each batch undergoes quality testing, according to the company.
CIT-25, SGR-28 and TRY-23 are available through the AmeraLabs online shop and authorised resellers.
Application-specific materials support open dental workflows
Dental 3D printing manufacturers 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.
