Prusa Pro HT90
The Only 3D Printer an Engineer Needs
The Prusa Pro HT90 is a delta kinematics 3D printer with a cylindrical print area (Ø300 × 400 mm) designed for advanced materials like ABS and PA. It features a heated chamber up to 90 °C, ensuring excellent layer adhesion and quality while preventing warping. With Input Shaper technology for fast printing and a swappable print head that reaches 500 °C for high-performance filaments like PEEK, it also includes a HEPA-filter recirculation system for air purification. The printer is user-friendly, supporting both offline operation for security and robust online print management.
Key Features of the Prusa Pro HT90:
- High-speed 3D printing with an acceleration up to 20000 mm/s².
- Features a servo flap that redirects airflow to precise areas of the model within milliseconds. Simultaneously, it prevents overcooling of the rest of the model.
- High-flow and high-temperature swappable printheads allow for rapid and versatile printing of any polymer-based filament.
- A unique cooling system paired with a HEPA filter to ensure a safe environment.
- Optimized to be a versatile solution for a wide range of industries and applications.
Maximize the Potential of Your Materials
The heated chamber of the HT90 can reach temperatures of up to 90 °C. Additionally, its innovative servo flap redirects airflow to specific areas of the model within milliseconds, maximizing the effectiveness of your materials.
- Exceptional layer adhesion and 3D print quality make it easy to produce large objects.
- The servo flap also allows for the 3D printing of flawless overhangs with minimal supports, preventing the 3D printed object from overcooling.
- The HT90 is engineered for materials such as ABS, ASA, PA, PCCF, Flex, and more!
Affordable Advanced Material Manufacturing
The Prusa PRO HT90 offers industrial-grade 3D printing at an accessible price. Designed for professionals, it features a high-temp print head, heated bed, and actively heated chamber, allowing for reliable printing with demanding materials like PEEK and PEI.
- Ideal for aerospace, medical, automotive, and industrial applications.
- Produces heat- and chemical-resistant parts, custom implants, and functional machinery.
- Its precision-controlled features ensure consistent layer adhesion and dimensional accuracy, making it suitable for rapid prototyping and small-batch manufacturing of production-quality parts.
Rapid Cooling and Clean Airflow
The Prusa Pro HT90 features a rapid cooling system with real-time airflow control, enhancing 3D print quality across various materials. Its side-mounted fan and high-speed airflow flap provide precise cooling for better overhangs and bridging without affecting the rest of the print. geometries.
- This system reduces ultra-fine particles in the chamber while maintaining consistent airflow.
- An automatic intake flap also helps manage chamber temperature for lower-temp materials.
- Ensures more reliable and consistent 3D prints.
Space Saver
