Product Description

Prusa Pro HT90 Maintenance kit is the official service and maintenance package designed directly for the industrial 3D printer Prusa Pro HT90. In one package, you get the tools, spare parts, and cleaning accessories you need for routine maintenance and basic servicing of the printer.

The kit is ideal for companies, laboratories, and workshops where the HT90 operates in continuous or demanding conditions. Regular maintenance significantly reduces the risk of downtime, ensures stable print quality, and helps keep the machine in top condition even when printing technical and high-temperature materials.

Package Content

The maintenance kit contains original components and tools intended directly for the HT90:

• High-temperature nozzle replacement tool – safe and precise replacement of high‑temp nozzles without the risk of damaging the hotend.
• Filament sensor – spare filament sensor for reliable detection of filament presence.
• Belt tensioner – tool for correct belt tensioning, key for printing accuracy and repeatability.
• HT90 spare parts set – selected replacement components for the most common service tasks.
• HEPA filters (2 pcs) – replacement filters for efficient air filtration in the actively heated chamber.
• IPA cleaning pads (10 pcs) – for cleaning surfaces and parts using isopropyl alcohol.
• Brass brush – gentle cleaning of the nozzle, hotend, and metal parts from filament residue.
• Gloves (10 pcs) – disposable gloves for safe handling of chemicals and hot parts.
• Scraper – for safe removal of prints and material residue from the print surface.
• Magball joint grease – special lubricant for smooth and precise movement of the delta kinematics.
• Microfiber cloth – non-abrasive cleaning of glass, covers, and optical/plastic parts.
• Screwdriver with three bits – universal tool for minor interventions and adjustments.
• Cleaning needles + spare noClogger needle – for cleaning and clearing clogged nozzles.
• Linear guide lubricant – high-quality lubricant for quiet and smooth movements along linear rails.

Detailed instructions for using individual tools and maintenance procedures can be found in the official Prusa knowledge base for the HT90 model.
