High Temperature Resin: Expanding the Possibilities of MSLA 3D Printing
November 7, 2025
Formero’s Masked Stereo Lithography (MSLA) 3D Printing service continues to evolve, with an expanding range of engineering materials designed for specialised applications. High Temperature Resin is a high-performance photopolymer developed for engineering parts that need to perform in extreme environments. With excellent thermal resistance and dimensional stability, High Temp Resin offers reliability where typical plastics fall short.
What Makes High Temp Resin Different
Many standard 3D printed materials begin to soften around 50-70°C, which can limit their use in functional or heat-exposed applications. High Temp Resin maintains its rigidity and strength well beyond this range, performing reliably in conditions that would cause other materials to deform. It delivers the kind of results usually associated with advanced polymers such as PEEK or PTFE, but with shorter lead times and a more cost-effective process.
Real-World Applications
Customers are already using High Temp Resin across a variety of industries and environments, including:
- Electrical and electronic components such as heater mounts, insulators, and motor coil housings
- Lighting and optical systems where heat and light intensity are a concern
- Prototypes for high-temperature assemblies in automotive, aerospace, and robotics
- Laboratory tools and fixtures requiring both stiffness and thermal stability
Its translucent finish is an added advantage in applications that benefit from visual inspection or internal visibility.
Why Choose MSLA for High Temp Resin Parts
When it comes to detail, surface quality and precision, MSLA 3D Printing provides clear benefits over traditional methods. It enables the creation of intricate, injection moulded-like prototypes with undercuts, hollow structures and thin walls, without the limitations or warpage risks of CNC machining polymers.
Producing heat-resistant parts through CNC milling can be time-consuming and costly, particularly when using advanced polymers such as PEEK. Metals, while durable, are heavier and thermally conductive, which can make them unsuitable for parts that need insulation or lightweight design.
With MSLA, engineers can produce complex, fluid-tight components that perform under heat with greater freedom and efficiency.
Designed and Finished by Experts
Formero’s team considers part orientation and support strategy to reduce warpage and achieve the best possible surface finish. While our MSLA build volume is generous, we recommend allowing some margin for orientation flexibility rather than designing parts that reach the full capacity.
We also offer a range of SLA-style finishing options, tailored to each project’s requirements, from functional prototypes to presentation-quality parts.
Ideal for Engineering Applications
High Temp Resin is designed for performance-driven applications. It is not intended for general-purpose parts or aesthetic models, but for when stiffness, heat resistance and precision are critical.
It is ideally suited to industries such as:
- Aerospace and automotive, in proximity to engines/exhausts
- Electrical and consumer products, that incorporate heater elements
- Robotics and UAV/drones, motors and battery mounts
- Laboratory and research
- Intense lighting, laser and optical applications
- Industrial workshop processes such as welding jigs & forming tools
- Safety, heat shields and hot surface guards
