Liqcreate Launches Certified Biocompatible Dental Impression Tray Resin for Open-Platform 3D Printers

Independent resin manufacturer Liqcreate has introduced Liqcreate Tray, a CE Class 1 certified biocompatible resin formulated specifically for producing custom dental impression trays. Developed alongside dental laboratories and clinical partners, the material targets open-platform 3D printers operating in the 385–405 nm wavelength range.

Open-Platform Compatibility and Technical Specifications

Many dental laboratories have digitised their workflows using intraoral scanners and CAD software, yet impression trays often remain manually produced using traditional acrylics. Liqcreate Tray aims to bridge this gap by bringing custom tray fabrication directly into digital production pipelines without requiring proprietary, closed-system hardware.

Key technical and processing attributes of the new resin include:

• Wavelength Range: Formulated for DLP, MSLA, and LCD printers operating between 385 nm and 405 nm.
• Layer Thickness: Supports printing at 200-micron (0.2 mm) layer heights to accelerate batch production speeds.
• Sterilisation and Disinfection: Compatible with standard clinical disinfectants and steam autoclave sterilisation at 121°C and 134°C.
• Post-Processing: Requires a standard two-step isopropyl alcohol (IPA) wash, a 30-minute drying period, and a 15-minute UV post-cure session.
• Certification: Holds CE Class 1 biocompatible certification for clinical safety during chairside and laboratory use.

Hardware Validation and Open Workflows

Because Liqcreate operates as an independent material developer rather than a hardware manufacturer, printer profile validation is critical. The company has published slice settings for accessible desktop resin printers from Creality, Elegoo, Anycubic, and Phrozen, alongside professional hardware from Prusa Research and Raise3D. Pre-tested slicer profiles allow labs to run the material on existing desktop equipment without extensive manual parameter tuning.

What This Means for South African Makers

For South African dental technicians, clinical practices, and specialised print service providers, open-material resins offer a flexible alternative to costly closed ecosystems. Local dental labs running budget-friendly MSLA or DLP resin printers can adopt biocompatible workflows without investing in dedicated, single-brand dental hardware.

The ability to print at 200-micron layer heights speeds up turnaround times, allowing local operators to produce custom trays rapidly. Furthermore, compatibility with standard autoclave protocols ensures that local practices can meet hygienic standards for implant work and restorative procedures using existing sterilisation equipment.

DC3D’s Take

Dental additive manufacturing has traditionally been dominated by high-cost, locked-down ecosystems that restrict material choices. Liqcreate’s decision to develop a Class 1 certified, autoclave-compatible tray resin specifically tuned for common desktop printers is a practical step forward for open-source digital dentistry.

While open workflows require operators to manage their own post-processing and quality control carefully, validated profiles for accessible hardware lower the barrier to entry. For small laboratories and print farms expanding into medical or dental accessories, materials like Liqcreate Tray demonstrate how open-platform desktop resin printing continues to broaden its functional reach.
