Ultrafuse PP

Ultrafuse PP is a PP filament rated to a 95°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 PP is an engineering-grade 3D printing filament built on a PP polymer base. With a heat deflection temperature of 95°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 PP 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 PP. Always confirm final values against the manufacturer’s official technical data sheet.

Nozzle & Hotend

Ultrafuse PP is not abrasive, so a standard brass nozzle is perfectly suitable — there is no need to budget for hardened hardware. Keep spare brass nozzles on hand as normal wear items, and retune flow/temperature calibration whenever you swap one. CSV designation: Standard Brass OK.

Enclosure & Chamber

Ultrafuse PP 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 Ultrafuse PP with a standard brass nozzle?

Yes. Ultrafuse PP is non-abrasive, so a standard brass nozzle is safe and recommended. There is no filler to wear down the orifice, so brass gives you the best thermal conductivity and surface finish at the lowest cost.

Does Ultrafuse PP require an enclosure?

Ultrafuse PP 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 Ultrafuse PP need to be dried before printing?

Store Ultrafuse PP sealed with desiccant and dry the spool before any critical print. As a rule of thumb, dry at 60-80 °C for 4 hours and print from a dry environment to protect layer strength and surface finish.
