Description

Freeprint Splint 2 385nm Resin is a light-curing, biocompatible 3D printing splint resin developed for the digital fabrication of dental splints, fixation keys, and transfer keys. Designed for DLP 3D printers operating at a 385nm curing wavelength, Freeprint Splint 2 385nm Resin is classified as a Class IIa medical device, giving dental laboratories and practitioners a documented material for splint and appliance production workflows.

Applications: Intended for dental laboratories and clinicians producing 3D printed occlusal splints, bite splints, and orthodontic fixation or transfer keys as part of a digital workflow.

Key Properties:

High mechanical flexural and fracture strength without becoming brittle
High initial hardness and final strength for consistent process reliability
Low viscosity, reducing material consumption and shortening cleaning time
Good polishability for a smooth, refined surface finish
MMA-free, odourless, and tasteless formulation

Technical Data:

Flexural strength: >80 MPa
Modulus of elasticity: >2000 MPa
Final hardness: >82 Shore D
Water absorption: <32 µg/mm³ Solubility: <5 µg/mm³ Curing wavelength: 385nm (DLP) Device classification: Class IIa Processing & Post-Curing: Non-polymerised residues are removed using a two-stage cleaning process with isopropanol in an ultrasonic cleaning device. Post-curing is recommended using light polymerisation units fitted with LED or xenon flash light sources under an inert gas atmosphere. Compatibility: This resin is formulated for compatible DLP printing systems calibrated to a 385nm curing wavelength. Always follow the printer and post-processing equipment manufacturer's instructions to achieve consistent results. Supplied clear/transparent in a 1000g bottle, suitable for dental laboratories running regular splint and appliance production.
