Liqcreate Separation Model: Dental Resin That Eliminates the Need for Separating Agents

A New Approach to Orthodontic Model Making

Netherlands-based Liqcreate has launched Liqcreate Separation Model, a specialised dental photopolymer engineered to deliver built-in non-adhesion performance toward acrylic-based dental and orthodontic materials, with no additional surface treatment or separating agents required.

Developed in close collaboration with established dental and orthodontic laboratory partners, the resin represents a departure from conventional model-making workflows. Where standard practice requires technicians to apply a separating medium before polymerising acrylic on the model, Separation Model makes that step entirely unnecessary by incorporating the separation agent into the resin formulation itself.

The Problem with Traditional Workflows

In orthodontic laboratories producing retainers, bite plates, and other cold-cure appliances, managing adhesion between printed models and acrylic materials has remained a persistent operational constraint.

In a typical workflow, a digital scan is converted into a printed model, which is then used to fabricate appliances such as Hawley retainers. To prevent the acrylic from adhering to the model, technicians apply a separating agent prior to polymerisation. This additional step introduces both time overhead and variability.

According to Liqcreate, incomplete coverage can result in localised bonding, while removal of a fused appliance risks damaging either the model or the prosthetic, often requiring the process to be restarted.

Built-In Separation

Most dental model resins are based on acrylate or methacrylate chemistry. Because these materials share a similar backbone with orthodontic acrylics such as PMMA, they tend to bond during fabrication.

Liqcreate Separation Model addresses this constraint at the material level by incorporating non-adhesive properties into the formulation. This enables direct application of cold-cure or self-cure acrylics onto the printed surface without a separate isolating step.

The workflow is reduced to standard printing and post-curing, followed by direct acrylic application using conventional techniques. After polymerisation, the appliance can be removed without the mechanical resistance typically associated with PMMA bonding.

Broad Printer Compatibility

Separation Model is compatible with most open-material DLP, MSLA, and laser-based 3D printers operating at wavelengths between 385 and 405 nm. The supported device lineup includes entry-level machines from Anycubic, Elegoo, and Phrozen through to high-end professional systems from Asiga and Raise3D.

The resin supports a broad range of cold-cure procedures including fracture repairs, clasp additions, minor prosthetic extensions, and chairside or laboratory reline applications based on self-curing denture base polymers.
