Innovative Rapid Cooling Solution

The unique air management system is designed for real-time airflow control and optimal print quality with all materials. The print fan is on the side of the printer, forcing air through a tube directly into the lightweight print head, while the high-speed flap redirects its flow within milliseconds, faster than any normal cooling fan can do. This enables vastly improved printing of overhangs while the layers in the rest of the print do not suffer from overcooling.

Additionally, a closed-loop air recirculation system with a HEPA filter keeps the chamber free of ultra-fine particles, while an automatic intake flap manages temperatures for materials like PLA and PETG, so you can print them with the chamber closed. The key components are placed outside the heated chamber, prolonging their lifespan.

Prints that are Large and Precise

Achieve unparalleled precision with the Prusa PRO HT90! We have tuned the print profiles so that you can design precise parts and work with great accuracy. The print volume is a full cylinder with a 300mm diameter and 400 mm tall Z-axis. The printer has a small footprint that is further enhanced by a vertically sliding door to save more space.

Swappable Print Heads

The print head is held in place using magnets. Simply detach it from the arms, disconnect the cable from the top of the printer and replace it with a different model. The High-Flow Print Head with a quick-swap 0.4mm Revo nozzle is the perfect choice for rapid prototyping with materials up to 300 °C. In contrast, the High-Temp head with an abrasive-resistant quick-swap 0.6mm Revo nozzle reaches up to 500 °C and enables printing with materials such as PEEK, PEKK, or PEI (Ultem). Both print heads are included with the HT90 and the hardware is compatible with all Revo nozzles with diameters from 0.25 - 0.8 mm.

Actively Heated Chamber with HEPA Filter

The printer’s actively heated chamber with a closed HEPA and carbon filter recirculation loop can reach up to 90 °C, providing an optimal environment for even the most demanding materials. Print large robust objects from ABS/ASA without negative side effects, such as warping or layer separation, use PLA for quick prototyping, and create durable objects from PEEK or PEI.

Maximum Security with Offline Mode

While the HT90 offers a comprehensive remote print management system and surveillance, the printer is fully prepared for a completely offline operation. You can even disconnect the Wi-Fi module from the printer. We do not collect information about your prints or your printer’s surroundings. No matter whether you’re developing a new-generation space shuttle or just printing tools for your workshop, no organization should be interested in this information.

Robust Remote Management System

You can access two fully-featured remote print management systems depending on your requirements. The HT90 offers both local and remote management modes - in the local mode, the printer can be reached only from the local area networks, but you can also add it into Prusa Connect, our secure remote print management system, so you can access it from anywhere. Furthermore, you can take advantage of the built-in camera for print monitoring and chamber lighting. Attaching an external USB camera is also possible.
