+1 for the heat reference. You'd be able to wrap something approaching 2-3 mm with enough heat. The thicker parts may experience some distortion. Leave a PLA part in a hot summer car and watch how much flexibility results!

@fred_dot_u Yeah, I've bent PLA around quite a bit for various reasons, usually to avoid layer line weakness or fasten things together. You can even make quite strong PLA rivets.

2x 0.2 mm layers will flex very nicely, but will crease and crack if you bend them sharper than a certain limit.

@R..GitHubSTOPHELPINGICE yes, they'll take quite a bit of abuse though, well within the parameters of the question. I use it often enough that I have a sheet lying around so I can cut pieces off it when I need to.

This isn't an answer because you specified you want PLA, but TPU works really great for this at a thickness of around 1-2 mm and it's indestructible. You don't have to worry about bending it too sharply and creasing it, or about it being brittle from being so thin.

I'm _really_ new to 3D printing, so I'll ask a naive question: Why not just print it to the desired curve in the first place? Or, is flexibility the purpose, and the Coke can example was simply a way of saying it needed to be flexible?

@FreeMan printing flat negates the need for supports and is stronger and faster with zero chance of failure regardless of complexity. So you could print a 5cm high logo on it's edge with a curve, but that is 250 layers and if it was thin would be a problematic and brittle print. Or you could print it flat faster, stronger and cheaper.

@Kilisi thanks. As I said, possibly a naive question. That mostly makes sense.

For text such as the Coca Cola label consider a negative image, i.e. a thin, flat, rectangular piece with letter shaped holes.

This question makes little sense, each material is different. It takes very little time to print test samples and try. Do that.

How thin should I print a logo so that it is flexible enough to wrap around a curved object?

# How thin should I print a logo so that it is flexible enough to wrap around a curved object?

(Asked by: username_0 on 2022-04-18)

I want to print out a flat object without any support structure straight onto the build plate of my ender 5. It's going to be PLA and I need it to be thin enough to still be flexible.

I don't have a picture available, but imagine that I wanted to print out the Coke Cola and then wrap it around a bland soda can, so that the logo is raised up slightly?

Alternatively, what is the best layer height to use, and how many layers should I use?

With PLA you can just heat it to curve around the object. I've done this with up to 2mm. Real easy with 1mm.

I haven't tried thicker but assume it would work ok.

You'd have to glue it though to make it stick. My attempts were just to shape the prints, I didn't want them sticking so I shaped them around a glass bottle.

If you want it flexible in it's own right, then I suggest 2 \* 0.2mm layers. I have a large 2 layer print in front of me that bends easily.

This can be rolled up into a tube, but as soon as you let go it will return to flat.

1 layer is even more flexible but tears along the lines with a bit of effort. So if you want it really flexible I suggest you print 1 layer at slightly lower than normal nozzle height to really get the lines melded together. Or a bit hotter than normal.

**1 layer, of whatever thickness your device can print.**

I did something like this to print letters for a flat sign. The letters were 1mm thick and didn't bend, but I'd accidentally printed quite a lot of brim lines which were a single layer thick, and they'd merged into each other.

The brim worked superbly as a "net" to hold the letters in place, so in theory you could print as little as one layer thick.

* Nozzle height will have to be exactly right to merge the lines together. There are no lines crossing-over on the next layer to help bond them all together.
* Let the print bed cool to ambient before removing it from the bed, to help keep the lines connected. Could take an hour or so.
* Use a wide flat scraper to pull job off bed - you might want to design in a "tab" that can be damaged while getting the tool started, and trimmed of later.
