TPU Filament Filaflex 70A 'Ultra-Soft' is a highly elastic TPU (thermoplastic polyurethane) filament whose properties make it comparable to silicone. It has a shore hardness of 70A, reaching up to 900% stretch before breaking.

The greatest advantage of this flexible TPU filament is its elastic property. After stretching, this flexible filament returns to its original shape without deforming or breaking.

The Filaflex 70A flexible filament is not suitable for All Metal hotends, as the filament may become stuck and not flow properly. It is also not recommended to be printed by machine or 3d printers with bowden type extrusion. However, if you have any doubts, please consult with us and we will advise you.

TPU filaments of the Filaflex range are characterized by their strong adhesion to the print bed, so they do not require a heated bed, blue tape, Kapton tape, lacquer or any other adhesive spray. Additionally, they are odorless and resistant to solvents and fuel. Printing with these filaments requires different guidelines than rigid filaments. Therefore, it is necessary to appropriately configure the 3D printer.

Applications

Filaflex 70A is non-toxic and can be in contact with the skin. Consult for medical or food use. It can be used to create pieces that require high elasticity such as:

– Insoles: orthopaedic insoles.

– Prosthesis and organ models: prosthetic arms, hands, organs for simulation of surgical operations,...

– Flexible objects and parts for industry, automotive: buffers, gaskets, tires, grippers ...

– Textile parts and accessories: textile garments, fabrics, printing on garments, bags, earrings,...

– Footwear: soles, shoes, sandals, sneakers,...

I really like this

I don't have a lot of 3D printing experience, but I have been able to get some very nice super-flexy prints of a product shell at 0.8mm thickness around the outside with this using a Ender 3 V2 with a Sprite Pro direct drive extruder.

I had slow the speed to 10mm/s and I'm using 240c temp and 0.32 layer height. The transparent also has a nice shiny Fresnel lens appearance.

Color seems to make a difference

It is a good filament very stretchy and resistant to tear with high elasticity, very difficult to deform permanently without heat.
The problem I have is it's tendency to clog and the need to constantly clean the gears of my extruder. It also has a very high humidity absorption.

All of this problems are explained by the company the only issue I have noticed is that the skin colored filament clogs frequently and it has been imposible to use. I have no issues with transparent and black

Buon filamento molto morbido e resistente e neppure troppo diffi

Buon filamento molto morbido e resistente e neppure troppo difficile da stampare con i soliti accorgimenti tipici dei filamenti flessibili. Usato per stampe funzionali in contato con acqua calda e detersivo. Sono soddisfatto.

Good Filament

It's a good filament and can be printed on a Prusa i3 Mk3S at 20 mm/s. It's *extremely* tear resistant. Don't heat the PEI bed and maybe use Kapton tape, else it will be nigh impossible so separate. However, 1 star is lost due to claiming it being resistant to acetone and solvents. I'm really a bit confused here, because it actually dissolves really happily in acetone and even ethanol. Can be a good thing though, if you accidentally welded it to your build plate...

Filaflex 70A in an upgraded Ender 3 Printer

My experience with 70A has been very steady so far. It’s been difficult but nothing I haven’t been able to handle yet. There have been many test prints and calibration prints. But I now have my 70A settings just how I like them. My printer is an old ender 3 with some upgraded bits. I’m running a microswiss direct drive kit, an e3d v6 hotend(attached to the microswiss cooling block), a PEI bed, and a silent motherboard. Most importantly though, is the 0.6mm nozzle. I had clogging issues occasionally on a 0.4mm and printing times were very long. But I’ve been able to print smoothly and consistently at a rate of 30-40% faster in most cases. My setup probably isn’t very optimal or effective for the time and effort it requires, but it’s been fun to grow my printing capabilities and knowledge through building it.
