Prusament PC Blend Carbon Fiber

Prusament PC Blend Carbon Fiber is a Carbon-Filled Polycarbonate filament rated to a 118°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 PC Blend Carbon Fiber is an engineering-grade 3D printing filament built on a Carbon-Filled Polycarbonate polymer base. With a heat deflection temperature of 118°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 PC Blend 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 PC Blend Carbon Fiber. Always confirm final values against the manufacturer’s official technical data sheet.

Nozzle & Hotend

Prusament PC Blend 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 PC Blend Carbon Fiber benefits from at least a passive enclosure — a fully enclosed chassis (or a draft shield) that traps the heat from the heated bed. This slows cooling, reduces warping and edge curling, and improves interlayer adhesion. An actively heated chamber is not required, but a warm, draft-free environment materially improves results.

Frequently Asked Questions

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

No. Prusament PC Blend 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 PC Blend Carbon Fiber require an enclosure?

Prusament PC Blend Carbon Fiber benefits from at least a passive enclosure — a fully enclosed chassis (or a draft shield) that traps the heat from the heated bed. This slows cooling, reduces warping and edge curling, and improves interlayer adhesion. An actively heated chamber is not required, but a warm, draft-free environment materially improves results.

Does Prusament PC Blend Carbon Fiber need to be dried before printing?

Polycarbonate absorbs moisture readily. Dry at 80 °C for 4-6 hours before use, and store it sealed with desiccant. Printing damp PC causes steam voids, poor layer bonding, and a cloudy finish.
