Material similar to Silicon

[FFSTECH 0]

Hi Guys,

 

Currently I have a gripper system in a robot to hold plastic bottles by the neck, the system consists in a silicon sleeve that get compressed (from top to bottom) then the outer diameter increases (catching the bottle by the neck).  I am considering in 3D print similar sleeves but using a different material.

 

I try making some parts with TPU but is still too rigid, any ideas about a good material?

Any thoughts on IROPRINT™ F 80213?

 

Thanks!

I think it will be hard to find something that has the flexibility, chemical inertness, long life, temperature resistance, stickyness and grip of silicone.

 

What you could do, is print a mould in PLA (or whatever), and pour your own silicone sleeves in it. Then you still need silicone of course, but at least you have the design flexibility you want, that off-the-shelf part can not give.
