    Hey all, I just created a Facebook group for no selling, aquarium specific, 3D printing. I have a few things I'm working on designing that I will share there. As we grow in members, we should see more ideas, files, and discussion. If you have a 3D printer, or want to buy one, and are an aquarist, you will definitely want to join. It's free, and will be a great resource as it grows. Here's the link.https://www.facebook.com/groups/A3DPC/

    Nice! I have been on the fence with buying a 3d printer and almost pulled the trigger a few times. Only thing that stops me is I really don't know how to CAD.

    That's the beauty of where the hobby is at right now. You can find a lot of items to print for free. I created what I hope will be a repository of Aquarium specific ones.

    I'd need to find the file, and it needs to be adjusted for the new bottle size/shape anyway. But I printed a basket to hang over the side of my sump to hold a bottle of Trident calibration fluid at the correct water height.

    Nice, what were you planning to print with it if you bought it?

    I just used the google machine to check out that shop maker. Not even in the market for one and that thing looks cool. Science is here to stay people.

    I think our president could use that integrated laser on aptasia.

    I have been thinking about one for a while, have not pulled the trigger yet. The kicker for me is some medias seems to disintegrate in water, I don't want unknowns added to my tank because of my own stupidity

    Black PETG is perfect for reef tanks, it's durable, won't degrade like other plastics, and the colorant is non-toxic. Nem Protect, the manufacturer of 3D printed Nem guards for MP10, MP 40, and Maxpect Gyres is all 3D printed with PETG. That being said, you'd have to print a LOT of stuff to make buying a 3D printer for this hobby worth the cost. The good news is, you can print a lot of other things for other aspects of life.

    I don't have anything that is submerged currently. Since PLA is biodegradable it will wear down faster, there is a reddit post where someone speculated it broke down quickly in their system due to using it as a filter media. Assuming that the bacteria consumed the PLA, similar to the way biopellets are consumed over time.

    ABS or PETG should hold up better. But I don't have first hand experience with any of them in water.

    It would also likely hold up longer if it was coated with epoxy, or spray painted with Krylon. Although that all depends on what you are printing since the surface texture could matter, or adding additional thickness could be problematic for something that is built as a replacement part or has multiple interlocking pieces.

    I understand it wouldn't be justified with just reef equipment. I also can't say what media was used but I have seen the stuff fall apart in freshwater that was sold as in tank use. Really makes me leary when putting in saltwater. And personally having seen krylon dissolve in saltwater would rule that option out for me as well. I know the lower end options for 3d printers limit the choice of medias but knowing I should look at something that will do abs and/or petg is helpful.

    That was most likely PLA, the most commonly used 3D printing filament. Most low end 3D printers can print PETG.
