It could be the additives to make them print easier, that may have the problem, but to be honest, I don't know.

Yes, for this you will need dual extruder, the easier "poor man's" solution is to go for variable density with solid TPU as the bones and low density infill TPU outer for the skin and soft tissue....

I am the UK beta tester for Filaflex, I also have NinjaFlex.

They are both Thermoplastic Polyurethanes (TPU).

The difference is the temperature they are extruded at during the manufacturing...

Because it is the Flexy-Hand 2 that was printed and fitted to Ms. Anderson, it would be nice if there was attribution to the design used, within this article.

You can link to the previous...

They look great spec machines but unfortunately the Bowden extruder effectively kills it's ability to print with flexible filament at a fast feed rate, which may be important for some.

"Acts of Gnome" do a similar initiative, only with ermmm - gnomes!!

I have uploaded a two part mould that you can print off and inject flexible sealant (silicon etc) into to make your own hinges. I have included the stl file in the original Flexy-Hand repository and...

That is exactly what I hoped, thank you for your comment.
