Phrozen Engineering Ultra-High Temp TR300 Resin is a purpose-built engineering resin designed for functional parts that must perform under real-world operating conditions. Built to deliver dependable, repeatable results, TR300 isn’t just another resin—it’s a material you can trust for precision, durability, and real-world resilience.
Why TR300 stands out
- Low Shrinkage for tight-tolerance fits: Achieve high dimensional accuracy in precision parts and assemblies where mating surfaces and clearances matter. TR300’s restrained shrinkage helps ensure your printed components align when assembled with real-world hardware.
- Low Viscosity & Low Odor: Easy to pour, easier to clean, and friendlier to work with in busy workshop environments. A smoother printing experience means fewer clogs, consistent layer adhesion, and less post-processing hassle.
- Heat Resistant: Maintains structural integrity at elevated temperatures, making it suitable for components that encounter heat cycles, warm environments, or near equipment that generates heat during operation.
- Tough & Impact Resistant: Designed to withstand mechanical stress, making it a solid choice for functional prototypes, fixtures, housings, and other parts where durability matters as much as accuracy.
- 405nm Compatible: Works seamlessly with Phrozen LCD 3D printers and other 405nm resin printers, providing broad compatibility and a straightforward printing workflow.
The TR300 resin family from Phrozen embodies the brand’s commitment to engineering-grade materials that bridge the gap between prototyping and real-world use. When you select TR300, you’re choosing a resin designed for repeatable results and dependable performance in demanding applications.
Ideal use cases
- Functional prototypes that will see heat exposure or thermal cycling, such as test fixtures and housing components for equipment.
- Jigs, fixtures, and custom tooling that require durable, accurate parts with tight tolerances.
- Mechanical components and end-use parts where impact resistance and reliable strength are essential.
- housings and enclosures for electronics or sensors that must endure elevated temperatures without deforming.
How TR300 compares to traditional resins
Compared with standard engineering resins, TR300 emphasizes a balanced blend of dimensional stability, heat endurance, and toughness. Its low shrinkage supports precise fits, while the combination of low odor and easy post-processing keeps workflows efficient. The result is a resin that not only prints cleanly but also performs reliably in the field, reducing the need for redesigns or material-induced fit issues.
What you’ll love in real-world workflows
- Rapid iteration cycles with predictable part behavior under heat and load.
- Accurate small features and functional pockets that stay true to CAD models after curing.
- Durable housings and mounting brackets for temporary or semi-permanent installations.
Practical tips for best results
- Start with the Phrozen Resin Guide for recommended print settings and post-processing guidelines. Settings can vary by printer model and build parameters.
- Handle with standard resin safety practices: wear gloves, work in a well-ventilated area, and cure parts fully to maximize heat resistance and mechanical performance.
- Wash prints thoroughly to remove uncured resin, then cure under appropriate light exposure to achieve optimal strength and stability.
- Store resin in a cool, dark place when not in use to preserve its viscosity and performance characteristics over time.
Why choose Phrozen for engineering parts
Phrozen has built a reputation for engineering-grade resins that deliver consistent performance, precise results, and user-friendly workflows. TR300 is a cornerstone for engineers and designers who need more than just a printable prototype—it’s a material that supports reliable testing, scalable production concepts, and durable functional parts. When you select Phrozen, you’re tapping into a lineage of printer-resin synergy that’s trusted by professionals who demand accuracy and toughness without compromise.
If you’re evaluating materials for high-temperature, high-stress applications, TR300 offers a compelling combination of low shrinkage, ease of use, and resilient performance. Pair it with your Phrozen LCD printer or any 405nm system and experience a resin that keeps pace with demanding engineering tasks—from concept validation to near-final functional parts.
