3d printer question

[kboogie]

I use PETG on a Prusa mini. Nothing else was changed out to make things for my tank.

I also use PETG on my Prusa i3 MK3S+. primarily make custom fittings for low pressure plumbing. Most recently I made an adaptor for a mini powerhead for my Sulfur Denitrator saving me over $200 on a peristalic pump.

Welcome to R2R! 'Food Grade' is not really practical at home. You need not only 'food grade' filament and equipment but also the equipment room. Reef tanks do not really need to be food grade. The biggest concern is that reef tanks usually have some UV component to the lighting. PLA in less UV resistant that PETG plus PETG is tougher than PLA. It is not stronger but its slight flexibility makes it less brittle.

Just use PETG and all will be well.

My first question is about 3d printing.

I am up to speed on food safe/grade fillament, but what about the machine does everything, the fillament touch need to be food grade? Tube between spool and print head as an example? Already have stainless nozzles. Is the small ptfe tube food safe? Just how picky do I need to be to be safe? A friend is building a large tank I would hate to wreck it.
Will be binging all the info on here for next few days. Cheers.

Don't worry about it too much. What matters are the chemicals that are able to leach out of the filament, but with pla and petg you will be fine. Pla becomes brittle after extended exposure to water though.
