One MAJOR consideration when making springs from plastic: creep. Virtually all plastics creep when held continuously under even relatively small loads, so polymer (plastic) springs will almost always permanently deform if they're continuously loaded. This is why pressure vessels are rarely made from plastics or, if they are, they are typically reinforced with something else (like a metal or carbon fiber sheath) that has a MUCH higher creep stress.
@Athune2 ай бұрын
Glad to see someone else already made this point. You can only store energy in plastic springs over very short periods of time, so the torsion example only really works if it’s for something like a pull-back toy car. Wouldn’t work reliably for something that unwinds slowly like a watch mechanism.
@charlesstaton81042 ай бұрын
The other major consideration is *material choice,* which plays into creep and every other important aspect of this. I have done weeks of systematic testing, printing dozens of spring geometries from just about every material out there, and it makes a HUGE difference. Just about every material that doesn't snap when compressed, permanently deforms the first time you compress it, and/or has unacceptable creep. The only material I found to make a decent spring was PC, and at that, I had to make the spring about 600% larger than it really needed to be, so that its compression would be limited to about 10%, so it wouldn't shatter when compressed. At the end of it all I concluded that unless you're making single-use fidget toys, 3d printed springs are a terrible idea, regardless of material or geometry.

Slant team: please do a video going into the nitty gritty of doing print-in-place assemblies, i.e. (vertically) how your slicer interprets 0.2 vs. 0.15 vs. 0.3mm gaps, and what happens next on subsequent layers, and (horizontally) what kind of gaps you need for axles, etc, and whatever other considerations (diagonally-oriented axles?) I'm not thinking of. Thanks for all y'all do!

I love springs but never 3d print them: Young's modulus of steel is simply a lot more, you can make a much smaller and tougher part with steel, but making steel springs is actually really easy and steel springs are much easier to design. I use a 2-part 3d-printed mandrel/coil guide that glues over a 3mm steel rod and make them in a hand drill chuck. with 3d printing you can make a perfect custom spring for a few pennies of wire.

Another great 3D printing design video. You're amassing quite the library that now constitutes an entire class in 3D design using practical examples. I've always seen the spiral spring described as a clock spring, whether used in a clock or not. 3D printing compliant mechanisms along with the rest of the part is incredibly useful. No springs to purchase. No assembly labor. I'm imagining four compliant towers at 45, 135, 225 and 315 degrees to support a rocker pad on top that actuates four push button micro switches at 0, 90, 180 and 270 degrees, possibly with a central push button that could also be depressed. This rocker pad is a common user interface input for 2D navigation or navigating through complex user interface menus.

One unmentioned application of spring I've been playing with is impact absorption -- I use a magnetic door hold-open for my garage/workshop, and have been toying with designs for a compact one-piece/one-material part that absorbs the impact of the door being slammed into/stuck to it. Using PETG as a kind of test because PETG likes to shatter, so far the best design has been about 4 months before shattering.

@@Proton_Decay Trying to imagine what you're referring to.... I assume it's a solid door with a spring hinge and you're using this in place of something like a piston damper on commercial doors? The downside to PETG is its prone to creep under load which might start reducing its effectiveness if the spring stays under compression when closed. Unless I'm misunderstanding I think something similar out of TPU would make more sense. It's softer, stronger and wont rebound as much.
@Alex_vGrafensteinАй бұрын
One of the most important tips is missing: Don't print anything that has to stay under tension out of PLA. Especially springs are a hot candidate. PLA will adopt the deformed state after a surprisingly short time and stay in the new form without springing back. PETG is much better for that. It happily keeps its shape for a long time.

You can make a decent coil spring out of PLA, but only by printing a winding jig from ABS or PETG and using hot water to wind the filament around the jig and letting it cook before removing. This spring type is limited to the filament diameter for the wire size and isn’t a very strong spring but it’s very popular as a bobble head spring.

Filament spring - design and print a spiral mandrel/jig (print in something higher temp). Wrap raw filament around it (petg has worked well for me). Drop the wrapped mandrel in a bowl of hot or boiling water to lock in the spiral. Obviously you are limited by filament diameter, but this is still another really useful spring.

@@RVJimD If you print it vertically I'd use a square coil and chamfer the edges so only a small area between each coil needs support. Or you could try printing a square coil horizontally with a brim and/or support on the outside only. Supports should come off fairly easy but it comes down to slicer settings. Keep in mind that many plastics will deform with use, especially the first time it's compressed so I'd make it longer than it needs to be.

I'm trying to design clips that will hold down but need to flex up to 1mm during install due to variance in the board production. These clips will be under tension, what material should I shoot for?

You're still printing in thin air, so you'd need exceptional cooling for this to work. And you're limited to the width your nozzle for thickness. And you can't embed it into another print. IOW, you need a very finicky setup to print a very bad coil spring very slowly and you end up with an isolated part that needs assembly. It's something you can do to show off your skills at calibrating your printer and slicer. But this video is about mass production 3D printing. And 3D-printed coil springs have no place in this context.
