Prusa Pro HT90 Delta kinematics 3D printer with a cylindrical print area Specifically designed to maximize the potential of advanced materials like ABS, ASA, PCCF and PA. Its heated chamber, which reaches up to 90 °C, and innovative cooling system, provide unparalleled layer adhesion and print quality. With the HT90, you can print large objects without any warping, poor overhangs, or layer delamination. Additionally, the Input Shaper technology enables ultra-fast printing prototypes from PLA, PETG, and similar materials, all of them easily printable even with a closed chamber. Main Features Ultra-fast Industrial printer Ø300 × 400 mm Build volume Nozzle temperature Up to 500 °C Bed temperature Up to 155 °C Actively Heated Chamber HEPA and carbon Filter Offline and online Operation Make the Most Out of your Materials The HT90 is engineered to maximize the potential of materials like ABS, ASA, PA, PCCF, Flex, and more. Its 90°C heated chamber provides unparalleled layer adhesion and print quality, enabling easy production of large objects without warping or layer delamination. The innovative servo flap redirects airflow to precise areas of the model within milliseconds, allowing the HT90 to print flawless overhangs with minimal supports without overcooling the printed object. Top Affordable Choice for Printing with High-End Filaments The high-temperature print head, high-performance heatbed, and actively heated chamber make the HT90 the most affordable 3D printer capable of handling high-end materials. Print small-to-mid-sized objects from such filaments as PEEK, PEKK, PPS, PSU, PES, and even PEI (Ultem), a material extensively used in the aerospace industry. Highlights of the Prusa Pro HT90 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. Make the Most Out of your Materials 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.
