3D printing your aquarium parts

3D printing your aquarium parts

For those of you serious DIY folks, you may be interested in how you can make your own plastic aquarium parts by printing them on a 3D printer. Just this year, costs for the 3D printers have dropped to under $500 USD for a pre-built one, and under $200 USD for a kit. 3D printing of your plastic parts works well when:

1. You are good with computers.
2. You like trying new designs or colors.
3. The part is small, or can be put together with small parts.
4. The part does not require great strength.
3. There is no easier/cheaper way to get the parts.

Some aquarium parts, such as simple boxes or tubes, are not suited to 3D printing because they can be more easily made with simple plastic or acrylic shapes. But some parts are so complex that there is no other way to make them except to print them on a 3D printer. I'll be using 3D printers to make the next version of algae scrubbers because of the built-in air tubing, magnet compartments, holes, and bubble pathways that make it impossible for the part to be made (in one piece) any other way.

Some things I've learned that pertain especially to 3D-printed aquarium parts:

1. Only use ABS plastic, not PLA or PVA. The ABS plastic is the same type of plastic used in kid's LEGO toys and is very strong. PLA or PVA plastic, however, will slowly dissolve when underwater or when subjected to high temps.

2. Only use FDM (also called FF) printers. These are the types of printers which use coils of plastic filament. These are also the cheapest printers. Other types of printers such as SLA (liquid) use a photo-cured plastic that will get brittle under aquarium lights, and "powder-printers" make parts which are not water tight.

3. The 3D printed parts will not be "glossy smooth". They will instead be more like carbon fiber, with a texture (or lines) running in one direction through the whole part.

We are too new at 3D printing to be able to recommend a particular printer, but I'm sure each reef or aquarium club has someone who has a 3D printer, and this is usually a great place to start.

Hi Santa,I´ve moved it to "equipment¨.
Very interesting and a sight of the future which is coming so fast :shock:
A 3D printing shop just opened few blocks away from home.
Thanks for sharing! :D

Excellent information, thank you.

How cost effective is it to print something like your scrubber using a 3D printer? What is the cost of the filiment that it takes to create an individual item?

Glad you like the info.

It actually adds greatly to the cost of the shell, but reduces the work required afterwards. Plus it looks much better :)

A roll of the the ABS plastic filament is about $40 per kilogram, which prints about 1000 cc's of solid plastic.

It's always better to use parts already made, especially larger parts like the case for a scrubber. Our new one is just so complex and curved that's it's impossible to make any other way. A windmill, however, would need to be made with already-made parts too, because the parts are too big.

Anyone have models to share? So far I have a very basic float switch bracket but I'm planning an auto feeder. I'll probably do some clips for dosing hoses etc. I've been using PLA so I guess I'll put in my ABS order.

Float switch brackets, auto feeders, hose clips, seem like perfect uses. Those and some coral models could be uploaded to Thingiverse for others to download and print.

The molding people at macna look to be the Smooth-On products. And the scrubber was a version of my old original waterfall design.

Im pretty good at Solidworks. I like the design of the HOG, very clever, i see what you did with the CREE LED on the outer part of the assembly, great idea! How are you going with it? If you need any help with 3D modelling I can be of assistance.

Cheers

Well we make the HOG's with plastic trays now. The printed version needed work, and would be more costly and heavy.

However my new idea is custom-numbered frag plugs: 3D letters and numbers, maybe red on a white or black background, that can be tie wrapped to frags. The model could be taken to a local printer on MakeXYZ.com and spelled out exactly what is needed.

Re: 3D printing your aquarium parts

Postby SantaMonica » Sun Jan 25, 2015 1:25 am

Nice to see you getting a printer!

There is a 3rd type of plastic to consider: PET

Here are the advantages:

Non-warping
No smell
No enclosure required
Build plate can be heated or not
Also known as polyester, PETG, PETT, PET+
Is what most soda pop bottles are made of
Does not degrade in water
FDA approved in the USA for for food contact
Does not absorb water or moisture from air
Not brittle
Is the most recycled plastic
Clear color is the most transparent of all filament materials
Uses about the same extruder temps as ABS


As for your #1 and #2, I don't have real answers, but based on PET, it might not be important.

3) Look at the Printrbot Metal Simple, Craftbot, PowerSpec, Flash Forge Creator Pro. These vary in features, but all will get the job done after some practice. The Cube uses very expensive proprietary filament.

4) All printers which have a roll of plastic filament, are also called FDM/FFF printers.

Number #1 through #8 are fine, except for the 2-color. You are going to be in for a headache by needing 2-colors. Stick with 1 color for now.

Re: 3D printing your aquarium parts

Postby Amie » Sun Jan 25, 2015 4:36 pm

Okay, I'm convinced...PLA bad. I just watched a video on the difference between PLA, ABS and PET. They took a lighter and heated each one. The PLA melted instantly into a water-like goo. The ABS caught fire, but kept its shape. And the PET just showed darker burn spots. So PET is definitely better, but twice the cost. I assume it will come down in price over time.

Would it be safe to assume that if a printer is made to print ABS, that it would also print PET? If so, that is the way I am going to go...using PET when I need translucent materials.

I am curious why you mentioned to not get a duel filament printer. Are they supposed to be hard to work with? I am sure this won't be my first 3d printer, so I agree with you on starting simple. It is nice that ABS is so easy to glue together with acetone.

I really appreciate your advice. And thanks for the info about Cubify, I didn't catch the proprietary filament issue before.

I don't think PET is always twice the price; many times it's the same (see sources below). Also, if you use MakeXYZ.com and search for people printing in PET, some of them actually charge less for PET because they don't need a heated enclosure.

Printing ABS more than a half inch high or so, usually needs a heated enclosure, whereas PET does not. So yes, a printer with an enclosure (and of course a heated build plate) will work for PET. Some PET suppliers even say no heated plate is needed, but from what I've read a heated plate always helps a lot.

Dual-extruder printers have trouble with the non-used head hitting your part. They have to be leveled perfectly to avoid this. A single head avoids this issue.

Postby Amie » Tue Jan 27, 2015 6:48 pm

You definitely do a better job at search than I do, some of those were a good price. About 1/2 of the links are selling 1 lb. PET instead of 1 kg, which puts the price at least double. [url]thingslab.com[/url] looks to be the most expensive, that is the kind of sites I was finding .. 1 lb. for $54. I am glad there are other stores selling it for less, I am definintely sold on PET now.

What is TPE? An anagram for PET? ;)

thank you for explaining the dual head, that makes total sense. I am sure that will be solved over time, but I will just have to wait on that.

If a 3d printer says you can only print PLA, that means they probably don't have a heated plate, right?

TPE is flexible rubber-like filament, which is very hard to print, and not water-safe.

PLA-only printers tend to not have heated plates, and usually always are not enclosed. But, anything can be printed on any printer, if you know what you are doing and make the needed adjustments and mods.

That's why I still have not got my first machine. I have other people print the needed parts for now.
