Formfutura CarbonFil
Formfutura CarbonFil 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
Formfutura CarbonFil 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 Formfutura CarbonFil 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.

Nozzle & Hotend
Formfutura CarbonFil 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
Formfutura CarbonFil 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 Formfutura CarbonFil with a standard brass nozzle?
No. Formfutura CarbonFil 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 Formfutura CarbonFil require an enclosure?
Formfutura CarbonFil 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 Formfutura CarbonFil 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.
