3D printing filament

[snyderman99]

Hey everyone! Does anyone have any tips for 3D printing items for my reef tank? What filament to use and if you coat it after?

I use petg. Pla is plant based (and compostable), and will degrade in the right conditions. No coating required.

Do you infill 100% or do you do less and it’ll still sink?

Same as above I use petg for aquarium parts….and almost everything else I print honestly.

I do 100% for sinking like frag racks, etc. but it might be possible if you use the right infill pattern to do less. It’ll also depend on the size of the print too.

Guys, where's a good place to find files for aquarium stuff to 3d print? Or, do you guys design your own stuff with software? I don't have a printer, but a friend recently got one.

I mostly design, but Thingiverse, Printables, and Cult3d are a few. I also upload designs to Bambulab Makerworld and Thingiverse.

Thanks, Matt!

I'd start here, and the whole forum has a lot of files available. thingiverse.com and printables.com are other sites where I've find useful files on.

Thank you, I guess I thought that subforum was just for people selling 3D printed stuff.

There's actually a separate forum for that.

For a reef tank, the biggest concerns are the safety of the corals and fish, as well as durability in saltwater. PETG is better than PLA—it is more chemically resistant, more durable, and still relatively easy to print. To protect the filament and prevent leaching, it’s wise to coat your prints with epoxy resin or a food-safe, aquarium-safe sealant. This creates a barrier between the filament and the saltwater, improving both longevity and safety.
