Filaflex 70A

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.

Super soft

Even softer than I expected, but printed without issues through my Revo XS extruder. (I printed quite slowly.) My first attempt at a bladder came out much too soft, but I swapped in a 0.8mm nozzle and printed with thick walls. No worries. Good stuff! Wonderful feel and stretchiness to this stuff, and perfect layer bonding.
