Prusament PETG: 1.75 mm Filament

# Prusament PETG

Overview

Prusament PETG is a 1.75 mm PETG filament manufactured by Prusa Polymers. It combines high toughness, strong layer adhesion, low warping, and relatively easy printing, making it well suited to functional and mechanically stressed parts.

Compared with PLA, PETG is more flexible, less brittle, and more temperature resistant. It is commonly used for engineering components, holders, clamps, printer parts, functional prototypes, and tooling applications requiring durable parts with good dimensional stability.

Prusament PETG is suitable for many 1.75 mm PETG-capable FDM printers already indexed on Print3DIndex, including the Prusa CORE One+, Bambu Lab A1, and Bambu Lab P2S, provided the selected printer and build surface are configured for PETG.

Technical Specifications

Note: Prusa Polymers recommends approximately 250 ±10°C nozzle temperature and 80 ±10°C bed temperature. Recommended settings can vary by printer, colour, build surface, and print profile.

Note: The approximately 47 MPa value is the documented tensile yield strength of a horizontally printed test specimen. Printed-part properties depend on orientation, geometry, settings, and test method.

Printing Compatibility

Compatible Printer Type

• FDM printers using 1.75 mm filament and suitable PETG temperature capability

Printer Requirements

• Heated bed recommended
• Enclosure not required
• No special hot end required for standard Prusament PETG
• Part cooling recommended

Compatible indexed printers include the Prusa CORE One+, Bambu Lab A1, Bambu Lab P2S, and Creality K2 Plus, all of which support PETG-class printing workflows.

Important: PETG can adhere very strongly to smooth PEI. Follow the printer and build-surface guidance for PETG and use an appropriate separation layer where recommended.

Mechanical Profile

Note: The Prusament technical datasheet reports 47 ± 2 MPa tensile yield strength for the documented horizontal specimen and 50 ± 1 MPa for the documented vertical XZ specimen. Mechanical properties depend on print orientation, settings, geometry, and testing method.

Processing and Handling

Prusament PETG is designed for conventional FDM printing and does not require a heated enclosure. Prusa Polymers recommends approximately 250 ±10°C nozzle temperature and 80 ±10°C bed temperature.

PETG may string or ooze more than PLA. Correct temperature, retraction, cooling, and validated slicer profiles help reduce these effects. Printers such as the Prusa CORE One+ can use manufacturer-provided Prusament profiles through PrusaSlicer, while other compatible printers should use validated PETG profiles for their hardware.

Colour and Finish

• Colour: Multiple colours available
• Finish: Generally smooth and glossy
• Transparent colours are available
• Selected matte variants are available
• Standard 1 kg spools and selected larger or refill formats are available depending on colour

Comparison Section

Note: These are general material-category comparisons. Exact properties vary by formulation, manufacturer, and print conditions.

Callout Section

Recommended use: Choose Prusament PETG for durable engineering parts, prototypes, and tooling that need greater toughness and temperature resistance than typical PLA without requiring an enclosed printer. It is suitable for PETG-capable machines such as the Prusa CORE One+, Bambu Lab A1, and Bambu Lab P2S.
