Prusament PETG Carbon Fiber

Prusament PETG Carbon Fiber is a PETG filament rated to a 80°C heat deflection temperature. This page collects its hardware, environmental, and handling requirements in one place so you can confirm your printer is up to the job before you load the spool.

Material Overview

Prusament PETG Carbon Fiber is an engineering-grade 3D printing filament built on a PETG polymer base. With a heat deflection temperature of 80°C, it is engineered for functional parts that must hold their shape under load and elevated service temperatures — jigs, fixtures, brackets, ducting, and end-use components that would deform in a commodity material.

Selecting Prusament PETG Carbon Fiber is a systems decision, not just a spool decision: the polymer base dictates your hotend, your chamber, and your drying workflow. The sections below translate the manufacturer’s data into the concrete hardware and environmental requirements your printer must satisfy.

Hardware & Environmental Requirements

The table below summarizes the hardware and environmental prerequisites for printing Prusament PETG Carbon Fiber. Always confirm final values against the manufacturer’s official technical data sheet.

Nozzle & Hotend

Prusament PETG Carbon Fiber is an abrasive, fibre-reinforced filament. The carbon or glass fillers will rapidly erode a soft nozzle, so a hardened steel hotend (or a carbide/tool-steel alternative) is mandatory. Expect noticeably higher extrusion torque as well, so confirm your extruder can sustain the flow before running long prints. CSV designation: Hardened Steel Required.

Enclosure & Chamber

Prusament PETG Carbon Fiber prints comfortably in the open air. No enclosure is required, though keeping the printer away from strong drafts or air-conditioning vents will still improve first-layer consistency and reduce edge lifting.

Frequently Asked Questions

Can I print Prusament PETG Carbon Fiber with a standard brass nozzle?

No. Prusament PETG Carbon Fiber is abrasive and will destroy a brass nozzle in short order. You must use a hardened steel (or carbide) nozzle — a tool-steel upgrade protects the hotend and keeps extrusion consistent over the life of the spool.

Does Prusament PETG Carbon Fiber require an enclosure?

Prusament PETG Carbon Fiber prints comfortably in the open air. No enclosure is required, though keeping the printer away from strong drafts or air-conditioning vents will still improve first-layer consistency and reduce edge lifting.

Does Prusament PETG Carbon Fiber need to be dried before printing?

PETG takes on moisture moderately. Dry at 65 °C for 4 hours if the spool has been exposed, and store it sealed. Slight dampness shows up as extra stringing and surface bubbling.
