Need Flexible Filament advice
Posted: Sun Sep 02, 2018 10:07 pm
Hey, I want to get some flexible filament for a couple of uses.
One is to print some stepper motor dampers. I don't like the Steel/rubber/Steel type I have, which only attach in 2 places to the frame and are rather thick making the cog end up near the end of the shaft. I realize a 1.2 mm gaskets between the motor and plate are not going to do as much noise elimination with the screws still in direct contact (or maybe with a flexible washer under the head) as a regular damper. But I am figuring the shaft will not be offset with the belt tight and 4 screws holding the motor.
So I need something that will absorb vibration but deal with the heat produced by the motor.
The other use would be the digits on a prosthetic hand or maybe a cover for the digits. I assume the flexible stuff has some tack to it more so than any of the normal hard plastics. Currently Lee Nail Tippi gells are recommended to cover the fingers https://www.amazon.com/gp/product/B0031 ... 2681K29930
So I see filament with a hardness of 85 and some at 95, I assume I want 85 for both applications?
Was going to grab some Ninja Flex but at $85 I don't want to choose wrong..
I see several other brands on amazon with smaller amounts (which would be good) but most were SH 95 and not recognizing the manufactures names as any of the big common companies I was a bit unsure if it would be a waste of money.
Edit, found the ninjaflex splash spools so I ordered a roll of black to try it.. still want to know what you all think about the options and what you have luck with.. Will be using the M2..
Thanks in advance!
