Dental model resin for clean separation from acrylic

Liqcreate Separation Model is a specialized photopolymer resin for 3D printing dental models that need reliable non-adhesion to acrylic-based materials. The resin is designed to produce accurate printed parts with a matt surface finish and predictable separation behaviour for direct polymerization workflows on printed models.

This dental resin is specifically engineered for orthodontic model applications where the printed model comes into direct contact with acrylic. The rigid material helps support a clean and dependable release during cold-cure acrylic system workflows.

Key features and benefits for orthodontic model production

• Non-adhesion toward acrylic: formulated to reduce sticking when acrylic-based materials are applied directly to the printed model.
• No separating agent required: supports workflows that do not require an added separating agent.
• Matt surface finish: produces a matte model surface suited to dental lab handling and appliance fabrication steps.
• Good accuracy: designed for dental model production where dimensional consistency matters.
• Rigid polymer behaviour: engineered for ortho model applications that need stable printed parts during downstream processing.

Mechanical properties and curing reference

Liqcreate Separation Model has measured polymer properties after 30 minutes of high-power LED curing at 60°C. Reported values are 36 MPa flexural strength, 1.8 GPa flexural modulus, 0.56% water sorpution, 1.97 kJ/m? IZOD impact (notched) under ISO 180, 12 J/m IZOD impact (notched) under D256, and Shore D hardness of 74.

The material also recorded a Pass result for separation to ortho acrylic using an internal test method. Post-curing reference conditions are stated as 30 minutes at 60C in the Formlabs FormCure (first generation) curing unit.

Use cases for dental labs and orthodontic workflows

This resin is suited to 3D printed dental models used for orthodontic appliances and related cold-cure acrylic system processes. The non-adhesive behaviour toward acrylic makes Liqcreate Separation Model useful when a printed dental model must act as a working form for direct polymerization on the printed part.

The combination of matte finish, rigidity, and predictable release supports dental professionals and labs looking for a resin tailored to ortho model fabrication rather than general-purpose model printing.

Important application note

Material properties can vary with part geometry, print orientation, print settings, and post-curing settings. Liqcreate Separation Model is not tested on biocompatibility, therefore the material should not be used for applications inside the human body.
