Ultrafuse PAHT CF15

Ultrafuse PAHT CF15 is a Nylon/PA filament rated to a 150°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

Ultrafuse PAHT CF15 is an engineering-grade 3D printing filament built on a Nylon/PA polymer base. With a heat deflection temperature of 150°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 Ultrafuse PAHT CF15 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 Ultrafuse PAHT CF15. Always confirm final values against the manufacturer’s official technical data sheet.

Nozzle & Hotend

Ultrafuse PAHT CF15 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

Ultrafuse PAHT CF15 is a high-temperature engineering polymer that demands an actively heated chamber. A passive enclosure alone cannot hold the ambient temperature this material needs to avoid warping, delamination, and interlayer cracking. Plan for a chamber capable of sustained elevated temperature and preheat the build volume before the first layer.

Frequently Asked Questions

Can I print Ultrafuse PAHT CF15 with a standard brass nozzle?

No. Ultrafuse PAHT CF15 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 Ultrafuse PAHT CF15 require an enclosure?

Ultrafuse PAHT CF15 is a high-temperature engineering polymer that demands an actively heated chamber. A passive enclosure alone cannot hold the ambient temperature this material needs to avoid warping, delamination, and interlayer cracking. Plan for a chamber capable of sustained elevated temperature and preheat the build volume before the first layer.

Does Ultrafuse PAHT CF15 need to be dried before printing?

Nylon/PA is highly hygroscopic and will absorb ambient moisture within hours of exposure. Dry at 70-80 °C for 4-8 hours immediately before printing and print from a dry box or dry feeder where possible. Wet nylon pops, foams, and produces weak, stringy parts.
