Prusa Pro HT90 3D Printer
Delivery is 10 to 14 days
The Prusa Pro HT90 is a delta kinematics 3D printer with a cylindrical print area (Ø300 × 400 mm). It is 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.
Equipped with a swappable print head featuring a high-temperature nozzle capable of reaching 500 °C, the HT90 also handles demanding materials like PEEK, PEKK, PPS, PSU, PES, PEI (Ultem) for small to medium-sized objects. This makes it the most affordable 3D printer for high-performance filaments. The built-in recirculation loop constantly purifies the air inside the chamber through a HEPA filter. Both the High-Flow and High-Temperature print heads are included in the package.The printer is easy to set up and configure, offering both a fully-featured offline operation for maximum security and a robust online print management system.
