Fillamentum Flexfill TPU 98A

Fillamentum Flexfill TPU 98A is a TPU filament rated to a 55°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

Fillamentum Flexfill TPU 98A is an engineering-grade 3D printing filament built on a TPU polymer base. With a heat deflection temperature of 55°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 Fillamentum Flexfill TPU 98A 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.

At a glance

• Polymer base: TPU

• Enclosure requirement: Open Air OK

Hardware & Environmental Requirements

The table below summarizes the hardware and environmental prerequisites for printing Fillamentum Flexfill TPU 98A. Always confirm final values against the manufacturer’s official technical data sheet.

Nozzle & Hotend

Fillamentum Flexfill TPU 98A 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

Fillamentum Flexfill TPU 98A 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 Fillamentum Flexfill TPU 98A with a standard brass nozzle?

Yes. Fillamentum Flexfill TPU 98A 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 Fillamentum Flexfill TPU 98A require an enclosure?

Fillamentum Flexfill TPU 98A 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 Fillamentum Flexfill TPU 98A need to be dried before printing?

TPU is mildly hygroscopic but flexible and prone to stringing when damp. Dry at 50-60 °C for 4 hours as needed and store it sealed with desiccant; a dry spool dramatically reduces oozing and stringing.
