Overview
The SprintRay Pro S is a next-generation dental 3D printer designed for speed, accuracy, and predictable chairside workflows. It introduces upgraded optics, enhanced heating systems, smart sensors, and support for specialty kits such as the Arch Kit and Crown Kit. This article provides a foundational overview for new users and teams learning the Pro S platform.

Key Benefits of the Pro S
- User Friendly
- Pro S is designed for easy adoption within dental practices. The interface, onboard instructions, and smart sensing help reduce training time and manual setup.
- Leading Accuracy
- All-glass optics and improved Z-axis structure provide uniform light distribution and tighter tolerances for detailed restorative work.
- Improved Throughput
- Optimized curing profiles and support for specialty kits enable significantly faster production for small-batch and chairside workflows.
- Onboard Intelligence
- Integrated sensors monitor tank placement, platform position, hood status, temperature, resin tank life, and other conditions to guide users through each workflow.
- Integrated sensors monitor tank placement, platform position, hood status, temperature, resin tank life, and other conditions to guide users through each workflow.
Supported Workflows
The Pro S supports a wide range of digital dentistry indications, including:
- Dental models (aligner models, wax-up models, study models)
- Night guards
- Clear retainers (model-less printing when using SprintRay Retainer)
- Denture bases and denture teeth
- Surgical guides
- Temporary restorations
- Crowns, inlays, onlays, veneers
- Hybrid denture workflows
- Small-batch restorative appliances

Optics and Light Engine
Pro S uses a refined DLP system featuring:
- All-glass optical engine for improved uniformity
- Balanced light output across the full build platform
- High-resolution projection optimized for restorative accuracy
These enhancements ensure improved fit, smoother margins, and consistent layer formation.
Resin Tank System
Pro S includes an advanced resin tank with integrated heating and RFID tracking.

Resin Tank Heating
- The resin tank cradle includes a built-in heater.
- Typical heating temperature: 35°C (up to 60°C depending on material).
- Heating improves resin flow, supports highly filled materials, and reduces peeling forces.
RFID Resin Tank Tracking
- Each resin tank contains a near-field tracking tag.
- The printer automatically logs tank life and usage.
- This helps users avoid printing with worn or expired tanks.
For full care instructions, refer to the Resin Tank Maintenance article.

Build Platform Heating
The Pro S build platform includes an onboard heater.
- The platform heats automatically to 35°C when installed.
- Warm platform temperatures improve adhesion and early-layer stability.
- Specific materials may require additional heating depending on their formulation.
This dual heating system (platform + tank) was introduced with the S-series and is not available on prior Pro models.
Specialty Kits: Arch Kit and Crown Kit

Arch Kit
Designed for rapid small-batch production.
- Prints up to two arches at once
- Print times as low as 13 minutes
- Ideal for night guards, models, and restorative appliances
- Smaller resin tank reduces material usage

Crown Kit
Optimized for high-speed chairside restorations.
- Very small platform designed for ceramic-filled resins
- Prints up to six crowns in under 10 minutes
Both kits feature hard-anodized platforms that resist corrosion and wear from ceramic and filled resins.
