3D printed parts longevity (1 Viewer)

[steveb]

I had a dosing tube holder basically crumble the other day.

I'm thinking its either the blue light or salt....or maybe the plastic it was printed with.

Anyone else had any issues?

Haven't really used anything printed in the tank. Possibly the UV lights or heat? I've seen videos where they bake printed parts and it makes them stronger and more durable.

Really depends on the material the most. UV can play a role in it, I've had 3D printed stuff and regular plastic molded stuff break down outside so I wouldn't be surprised if that was the main cause.

PLA plastic is a big no-go. (PLA is also probably the easiest to print and the most common).

ABS can stand up to S/W, but is more "old school" and not that easy to print.

PETG is "food grade" so it is the preferred material. I've had stuff under-water for over a year and it hasn't shown any "breaking down".

Of course there's plenty of other types (tpu, nylon, ultem, sla resin) but I don't know how they all would do under water.

Use PETG over PLA.

I didn’t make it so I have no idea what it’s made from.

You can also get pvc printed as well. That’s likely the best for saltwater.

100% u had PLA. it doesnt hold up to salt water at all. i used to print alot of stuff and ABS always did well.

besides the longevity, what is wrong with pla?

If you need another one I would be happy to make one for you out of ABS or PETG. Here is some of my work: by GotfrogsDesign

What is with the number 14? Did I find something special?

I’m just bumping up the Easter eggs that were hidden so that people can see them.

I guess I missed the event. I did not even know that was a thing.
