Is Flexmark 7,8,9 compatible with Ultimaker S5?

[ChrisYu 0]

Hi there, I was trying to use a flexible filament recently, which called Flexmark 7 (https://treedfilaments.com/3d-printing-filaments/flexmark-flexible-tpu/).

So I was wondering whether it is compatible with the Ultimaker S5 or not? Will it damage the printer if I directly use this filament? If it is not compatible with the Ultimaker S5 with default setting, will it work if I change the extruder? Which extruder should I change?

 

Thank you sooo much for any answer that you can make!!!

Hi @ChrisYu,

 

Thank you for your message. I've never printed with it before so I don't know for sure. But I see on the site that it has a hardness of 70A, which is quite soft. I believe the most flexible materials we have in our marketplace hover around 80A, which is just a little bit less flexible. Flexmark 8 or 9 are closer to the materials we have in the marketplace. 

 

You could try it, it wouldn't harm your Ultimaker. If it turns out to be too flexible, it will have difficulties pushing it through the bowden tube or push it through the feeder. But no harm should come to your machine. 

Do make sure you try the 2.85mm filament tho!

Hi @SandervG

Thank you for the answers. BTW why should I use 2.85mm? What will happen if I use 1.75mm filament? Since I found another place to buy Flexmark 7 (https://www.sigmaaldrich.com/catalog/product/aldrich/trd3d0041?lang=en&region=AU&gclid=Cj0KCQjw0Mb3BRCaARIsAPSNGpVhWaFKBpcTbs8XgBifjgX7ZmXP7jDrMEMiKLHLYLzoEs2nuZZg0UoaAo-PEALw_wcB), which is more convinent for me. Is it fine to use this 1.75mm filament?

 

Thank you.

@ChrisYu - do not get 1.75mm filament!  Particularly flexible filament.  Even a stiff filament like PLA won't work very well in an S5 if it's only 1.75mm in diameter.  The hole is 3.1mm in diameter in the core and the hot filament will just come back upwards instead of going out through the nozzle (well some will go out the nozzle and some will go upwards).

 

There are MANY other sellers of TPU filaments.  Ninjaflex, Ultimaker, and many more.

 

What country are you in?

 

It's extremely rare for a filament manufacturer to make only 1.75mm but some sellers only sell one size.  90% of filament sellers sell both sizes.  Sometimes it's called "3mm" but it's actually 2.85 or 2.9mm.

Thank you @gr5 ! I am in Australia now. I think Flexmark 7 is hard to buy within Australia. But I am not sure about Ninjaflex.

But thank you anyway.
