Phaetus aeFlex™ TPU-78D 1kg Spool
Couldn't load pickup availability
Phaetus aeFlex TPU-78D is a high-hardness, semi-rigid TPU filament. At Shore 78D it sits at the stiff end of the flexible spectrum - nothing like a soft 95A. The higher surface hardness and modulus mean it pushes through the extruder without buckling, so you get the success rate of a near-rigid material plus TPU's impact and abrasion resistance.
What it prints well: durable functional parts that need toughness without floppiness - snap-fit enclosures, bumpers and protective housings, semi-flexible brackets and jigs, gaskets and seals that must hold their shape, and reinforced living hinges.
Print settings (Phaetus TDS)
- Nozzle / print temp: 210-230 °C
- Bed temp: 50-70 °C
- Build surface: glass, PEI film, or PC film
- Print speed: 30-120 mm/s. Direct-drive extruders handle ≥100 mm/s comfortably; Bowden setups should stay 30-60 mm/s.
- Cooling fan: on
- Nozzle: standard brass or plated-copper. This is an unfilled TPU - no glass or carbon fiber - so it is not abrasive and does not require a hardened or DLC nozzle.
Drying - read this
TPU is hygroscopic. Wet filament oozes, prints with bubbles, and finishes rough. Keep the spool in a dry box below 15% RH once the vacuum bag is opened, and reseal in the original foil bag when not printing. If it has picked up moisture, dry at 70-80 °C for 4-6 hours to restore print quality.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
