This filament is for advanced users only.  This requires a direct drive extruder. We have successfully printed using a Flexion or a "Proper Extruder" which can be printed and has minimal parts costs.

  • A PTFE lined heatbreak is recommended. No "all-metal" hotends as the metal causes excess friction.
  • It is recommended to have a hotend specifically for printing this filament.  Any leftover residue from other filament will easily cause jams.
  • Disabling retractions will give you the best results.
  • Speed benchy contests are not recommended.

Finally a filament that utilizes the full potential of the Flexion Extruder. This is, by far, the most flexible filament on the market. It feels like a rubber band, and produces finished parts that are completely tactile, flexible no matter what infill you use, and highly functional for applications that require stretch, flexibility, or compliance. 

TPU 60A Ultra-Flexible Filament is the softest filament available on the market today, by far. At Shore 60A, it is much softer than Ninjaflex or Filaflex. It is about the flexibility of an inner-tube. This material is perfect for that ultra-flexible application: rubbery toys, comfortable wearables, parts that need to stretch to fit, gaskets, releasable molds, and so much more.

  • Non-toxic.
  • Incredible flexibility and elasticity.
  • Diameter of 1.75; variations ± 0.05 mm; roundness ± 0.05 mm
  • Recommended for use with a PTFE lined hotend (not all metal).
  • Shipped vacuum-sealed with desiccant to keep it free of moisture (not prone to moisture absorption, but best to be careful)

Recommended print settings:

  • Print on unheated, solvent-cleaned polymer surface such as Buildtak, PEI, Kapton.
  • Print speed – up to 20mm/s. Start very slow (10mm/s) and work up from there. Slow down for bridging and infill.
  • Extrusion multiplier – 1.2 compared to rigid material

Print it right with Spool3D flexible TPU 3D printer filament.  Our flexible TPU filament is manufactured with tight tolerances from premium grade material.  Our filament has been tested on popular fused filament fabrication desktop 3D printer platforms.

TPU filament should be stored in a resealable plastic bag with the dessicant pack provided.

  • 1.75 mm TPU (Thermo Plastic PolyUrethane; tolerance +/- 0.02mm)
  • Optimum extrusion temperature: 230-260 degrees celsius

Filaments Unusable Because Too Thin. Poor Quality Control.

1/5
Could not get it to print despite using my direct drive and having worked with super soft TPUs previously. After hours of troubleshooting I noticed the filament is simply not up to spec, with the diameters ranging from 1.55mm to 1.65mm, which is far from the advertised 1.75 +/- 0.05, and so the gears couldn't grab onto the filament and apply enough pressure for printing. I thought I'd contact support about it first before leaving a review but received no reply even after 11 days of waiting.

Difficult but possible!

4/5
This has been an adventure and a half experimenting with my Ender 3 S1 Pro but I'm finally getting it to print at 95% reliability with a 0.8mm nozzle. If anyone has information on print specs or things they found useful for printing this please let me know. One thing I notice is that in the description for this product online is says optimum extrusion temperature is between 230-260 degrees but on the spool I have it says 200-220. What is actually optimal in case one was a typo? I keep getting popping but I've dried several times and I'm unsure if I just have my heat too high and it's causing the rubber to boil off which I'm confusing for moisture bubbles. Either way this is definitely a filament for pros but not impossible to print with
