The Prusa Pro HT90 features an innovative delta kinematics system with a spacious cylindrical print area measuring Ø300 × 400 mm. This design enables exceptional precision and stability throughout the printing process, particularly when working with challenging materials. The delta configuration allows for faster printing speeds while maintaining accuracy across the entire build volume.

Superior Thermal Management

At the core of the HT90's capabilities is its advanced thermal management system:

• High-Temperature Chamber: The fully enclosed chamber heats up to 90°C, creating an ideal environment for printing advanced materials
• Consistent Temperature Distribution: Engineered to maintain uniform heat throughout the chamber, eliminating cold spots that can cause warping
• Innovative Cooling System: Strategically positioned cooling elements provide targeted cooling exactly where needed, enhancing layer adhesion and print quality

Material Versatility

The HT90 excels with a wide range of materials:

Standard Materials

• PLA, PETG, and similar filaments print with exceptional speed and quality even with the chamber closed
• Input Shaper technology enables ultra-fast printing of prototypes without sacrificing quality

Advanced Materials

• Perfect environment for ABS, ASA, PCCF, and PA, eliminating common issues like warping and layer delamination
• Ideal for large-scale projects requiring structural integrity and dimensional stability

High-Performance Engineering Materials

• The high-temperature nozzle (500°C) handles demanding materials like PEEK, PEKK, PPS, PSU, PES, and PEI (Ultem)
• Makes professional-grade engineering plastics accessible at an affordable price point

Dual Printing Heads Included

The HT90 comes complete with two specialised print heads:

1. High-Flow Head: Optimised for rapid prototyping and standard materials
2. High-Temperature Head: Engineered for engineering-grade materials requiring extreme heat

The swappable head system allows for quick transitions between different printing requirements without extensive reconfiguration.

Health and Safety Features

• Built-in air recirculation system with HEPA filtration continuously purifies the chamber air
• Reduces harmful VOCs and particulates when printing with engineering materials
• Creates a safer working environment for users, especially in enclosed spaces

User-Friendly Operation

• Intuitive interface for both beginners and experienced users
• Fully-featured offline operation ensures maximum security for sensitive projects
• Robust online print management system for remote monitoring and control
• Quick setup and configuration process gets you printing faster

Professional Applications

The HT90 is particularly valuable for:

• Engineering prototypes requiring high thermal resistance
• Medical applications needing biocompatible, sterilisable materials
• Automotive parts demanding structural integrity
• Aerospace components requiring lightweight yet durable properties
• Industrial tooling and manufacturing aids

Value Proposition

The Prusa Pro HT90 represents the most cost-effective entry point into high-performance material 3D printing, bringing capabilities previously available only on industrial machines costing significantly more into a more accessible price range for professionals, small businesses, and serious enthusiasts.
