Need recommendation for a flexible filament

Greetings All,

I have seen some printed projects that incorporate a spiral springy component that is used to power a car, clock or some other fun motion toy.

Not sure what filament has that kind of functionality.

I have done some research but have no experience or exposure with any filament product with these properties.

Any recommendations?

Any hints?

Any bewares/cautions?

Thanks to All that reply.

PS: Just picked up some PLA+ from a local supplier but she could not help me with selecting a flexible filament.

RE: Need recommendation for a flexible filament

actually most printed coil springs use a non-flexable material. flex materials are used when you need the cushioning or hinging of a soft material. I've printed the "auto-rewind" spoolholder springs in both PLA and PETG

David/Rusty,

I will second that.  It's most likely a PLA/PETG spring.

The spool idea is interesting and I have the designs for several different spool re-tractors to go with the Lack enclosure for the MMU that I am building.  The current front runner is the weighted nut version as I can fit 3 of them into some Samla (dry) boxes that I got from Ikea.

No springs in those though.  I am not sure of the lifespan of the PLA printed ones.  I just haven't had time to get there yet.

https://www.thingiverse.com/thing:3697106 <- Uses weights to retract the filament

https://www.thingiverse.com/thing:2119644 <- Uses FLEX for the gasket.

Rusty,  Think of your rubberized phone case as FLEX material and you will understand it better.  It's more of a gasket material extruded like rubber rather than melted plastic.

Thanks @big-bird & @david-a66.  I saw a project that I like but some of the parts were made from a filament that had the word "FLEX" in the description, so maybe I am understanding this wrong.  The gasket reference is a good reference, that makes sense.

I'm always interested in new projects.  Just can't always get around to them.  You can post the link or Thingiverse number here and I could research it for you.  But if it calls for Flex it must have a reason for using flex.  Just know it wouldn't make a good spring.  😉
