I was very surprised to get a nice print - simple rectangle on the first try. I expected to have to make several attempts. I'm looking forward to doing something more complex this weekend - a drone housing for a GoPro. Anyone have advice for bridging success with Cheetah? Also on an M3


what print speeds did you use? surely not the same as PETG speeds?

Actually I did use petg speeds which are pretty slow. Worked perfectly with cheetah.

I haven't played with flexible stuff yet, but I can definitely see a use for it. My application would be padded vise jaws with cavities shaped to securely hold delicate parts. Something fairly firm would be good, with lots of traction to avoid slipping, and it needs to be tough enough not to tear. Soft wobbly stuff won't work very well.

I took a quick look at Ninjaflex, and it has a Shore A hardness of 85, which is actually pretty good. Typical O-ring material is 70, and hard O-rings are 90, so it's right up there. Cheetah is actually a bit stiffer, at 95. Both are very pricey. I noticed both are listed as having a "low friction exterior" for ease of feeding, which might be an issue unless it's got more traction once it's printed.

I realize these aren't the typical requirements, but I was wondering if anyone can recommend a filament to try for this sort of application?

Thanks!

This stuff is pretty good. It might be slightly stiffer and tougher than Ninjaflex and is definitely less expensive.

They are kind of short on real specs. I'll contact them & see what they say about hardness.
