85A
About as firm as a shoe sole
Softest we stock.
Stretches a long way and springs straight back. Squash it in your hand and it gives easily.
Good forSoft grips, vibration pads, squishy toys, cosplay parts
PrintingThe fussiest of the lot. Go slow and use a direct drive extruder.

About as firm as a rubber doorstop
Very flexible.
Bends without much effort and holds its shape when you let go.
Good forDrone bumpers, watch straps, seals, soft grips
PrintingStill soft. Slow it down and keep the filament path short.
95A
About as firm as a phone case
The standard TPU.
The one most people mean when they say TPU. Properly flexible, still easy enough to print.

PrintingPrints on most machines, Bowden included, as long as you slow down.

68D

Stiff.

PrintingPrints much like PETG. Dry it first.
70D
About as firm as a chopping board

Stiff enough that you would not call it rubbery any more.
Good forStructural parts that still need to take a knock
PrintingPrints much like PETG. Dry it first.
75D
