Prusament PEI 1010 Natural 500g (NFC)

Product description

Prusament PEI 1010 Natural 500g (NFC) is a top-tier industrial filament manufactured by Prusa Polymers / Prusa Research. The base material is polyetherimide (PEI 1010, often referred to as Ultem 1010) – one of the most durable polymers used in FDM/FFF 3D printing.

This material is designed for highly stressed functional parts that must withstand high temperatures, chemicals, mechanical stress, and radiation long-term. Thanks to this, it is ideal for the aerospace and automotive industries, industrial automation, manufacturing of jigs and fixtures, and replacement of metal parts.

The spool is equipped with an NFC tag, which allows for easy loading of production parameters and tracking of a specific filament batch in compatible systems.

Warning: PEI 1010 is not suitable for standard desktop printers Prusa MK, MINI, or XL – it requires a specialized high-temperature printer with a closed and heated chamber (approx. 90 °C and more).

Key features

• Material PEI 1010 (Ultem 1010) – top high-performance polymer for demanding industrial use
• Excellent mechanical properties – high strength, stiffness, and resistance to creep deformation
• Very high thermal resistance – suitable for functional parts operating long-term at high temperatures
• Excellent chemical resistance – resists a wide range of oils, fuels, solvents, and industrial media
• Self-extinguishing material, resistant to flame spread, suitable for applications with fire safety requirements
• Resistant to gamma radiation, suitable for specific medical and technical applications
• Possibility of replacing metal parts – high strength-to-weight ratio, potential to replace aluminum components
• Precise diameter tolerance 1,75 mm ± 0,05 mm – consistent flow and dimensional accuracy of prints
• Production under own brand Prusament – full quality control, detailed batch tracking
• NFC tag on the spool – simple identification and loading of spool data

Recommended use

Prusament PEI 1010 Natural is particularly suitable for:

• Aerospace and automotive – brackets, fixtures, covers, components in engine compartments and technical units
• Industrial tools and fixtures – assembly jigs, welding and measuring fixtures, parts for robotic workstations
• High-temperature functional parts – valve bodies, sensor covers, electronics holders, parts near heat sources
• Metal part replacements – lighter structural components with high strength and temperature resistance
• Specialized technical and medical applications (where appropriate standards and certifications allow)

3D printer requirements

PEI 1010 places significantly higher demands on the 3D printer than common materials (PLA, PETG, ASA, etc.):

• High-temperature hotend capable of long-term operation around 410 °C
• Heated bed approx. 150 °C
• Closed and heated chamber at least around 90 °C to limit internal stress and deformation
• Bed surface capable of long-term endurance of high temperatures (e.g., HighTemp powdered PEI sheet)

The material is intended primarily for printers of the Prusa Pro HT90 class or other industrial high-temperature FDM/FFF systems with similar parameters.

Recommended print settings

Specific values may vary by printer, but orientational:

• Nozzle temperature: approx. 410 ± 10 °C
• Bed temperature: approx. 150 ± 10 °C
• Chamber temperature: 90 °C and more
• Recommended print surface: high-temperature PEI sheet / HighTemp surface
• Print speed: rather lower, with emphasis on quality and layer adhesion

Before printing, we recommend starting from official manufacturer print profiles and performing tests on smaller samples.

Material handling and drying

PEI 1010 is highly hygroscopic, meaning it readily absorbs moisture from the surroundings. This can lead to:

• bubbles on the print surface,
• impaired layer adhesion,
• lower strength and rougher surface.

Recommendation:

• Thoroughly dry the filament before every print according to manufacturer recommendations (in a specialized dryer or drying oven designed for filaments).
• During printing, keep the spool in a closed, dried filament chamber / dry box.
• Store in a well-closed package with desiccant.

Safety and recommendations

• When printing at very high temperatures, ensure good ventilation or local fume extraction.
