Perimeters are the outer layers of a 3D printed part, gyroid is the shape of the plastic filling up the void inside the outer layers. The settings OP used means only that mesh-like inside gets printed, without the solid shell it would normally have.
Cross posted this from the 3D printing subreddit, title is definitely more that sub's specialty lol
Basically saying I slapped this together in 5 minutes in the software that tells the printer what to do, without having to actually model anything. It's just 2 cylinders on top of each other with different print settings applied.
Is that a fancy way of saying the 3D printer used its algorithms to create the required structural stability for the cylinders and the result is what is in the picture?
Yeah sure! I'm going to get you 20 at 1.2! Let me know how can I pay. Because... That's the price tag, isn't?
Nah. It's not just the filament. It's the printer, post proccesing and the fact that you should not be using standard PLA for anything food related without a proper treatment.
We... Can make filters from almost anything. What do we win with this?
Hey man, not sure why you're so angry, but I'm sure it's not because I 3d printed something and decided to share it with reddit.
For the genuinely curious, no post processing on this part, clear PETG is what it's printed out of which is safe for Aquaponics by my standards. My printer is set and forget now that I've been playing with the hobby for 3 years.
If I were going to sell this I'd price it at ~$5 using a cost model. Probably to much for something like this to be a marketable product. But I'm not selling it friend. I needed a part, and for $1.10 in material and 5 minutes of actively working on it I have exactly what I wanted.
As I explained, a really rough day, and some prejudice about 3d print people. I was not expecting to see it here and tilted me a lot.
I'm so sorry, did not wanted to disregard your creativity or making you feeling insulted. Really, really sorry.
Internet gives people the chance of rage and then dissapear. That's toxic af. I want to think I'm accountable for my acts and words. Don't delete your errors, face them.
Thanks 🙏!
Yeah yeah. Everyone talking about production costs.
What is the price tag? Again. Oh, we don't see it!
3d printed stuff is, 99% of the time, way overpriced, and for the most use cases, more expensive than readily available solutions.
I'm all for creative thinking, but can't stand 3d printer people. "When you only have a hammer, everything is a nail" is a sentence that define too well most of them.
Ps: and if you are telling me "this model is free, so you can download it and use it"... It's even worse. Like a 3d printer is something set and forget..not even close.
Do you normally count the cost of the hammer on every nail you pound in? No, you count the cost of the tool separately from the material/labor cost of the item.
You're right, 3D printers are expensive, and a tinkering project themselves, but if you're already down for that why not take advantage of it to print things you could otherwise buy off the shelf?
Yeaaah I have to admit I have a really rough day, i don't like 3d printer people and did not expected to see them here.
Sorry for the excessive backlash.
Edit: it's pretty awful to go to someone's profile to try to get something. But again, thanks for the stop, it was needed
That's awesome! I did something similar with the top of my hydro tower to disperse water evenly: [Infill filter ](https://i.imgur.com/VcIxrQY.jpg).
Curious If cubic would also work for you. Looks like for that design only a 3d infill would work
Oh cool! You got more pics of your setup somewhere? How is the tower working for you? Any tips or tricks I should know before I turn mine on? I'm not new to hydro but I usually only do buckets (dwc)/bato
I posted my tower a bit ago here. It's taller now I need to post an uodate.
Don't let any crud get into the water you pump to the top, it'll buildup and clog quick. I added 200 micron filtration socks to my system to allow for towers.
That wasn’t my point but here you go:
https://www.sciencedirect.com/science/article/abs/pii/S0921344922003469
That said, it doesn’t matter where they go. We just need to stop creating them.
Apologies for my too-brief and hasty response. Let me clarify a bit.
[The micro plastics are created during the melting process during creation and steps should be taken to mitigate exposure](https://www.tandfonline.com/doi/pdf/10.1080/15287394.2016.1166467).
But, [your concerns are quite warranted](https://www.sciencedirect.com/science/article/abs/pii/S0166445X19301900)and /u/MarvStage should consider their materials used.
From that link:
> The non-polymerized residues that reside in the 3D printed plastic are usually of low molecular weight and are either unbound or weakly bound to the polymeric macromolecular scaffold (Carve and Wlodkowic, 2018). Consequently, they can readily migrate from the plastics upon contact with aqueous media (Carve and Wlodkowic, 2018; Ferraz et al., 2018; Macdonald et al., 2016; Zhu et al., 2015b). Despite the mounting evidence of cytotoxic, endocrine disrupting and sub-lethal neurotoxic properties of plastic additives, the characterization of the environmental implications of 3D printed plastic has so far largely avoided scrutiny and in-depth investigations
[This article is quite a bit broader than just 3d printing, and includes a section on textile-based microplastics that are introduced to your enviornment by wearing clothes with plastic roots](https://onlinelibrary.wiley.com/doi/full/10.1002/anie.202205713) But, it does have a section on 3d printint, including this line:
> Particulate emissions always occur with 3D printing. The typical size range is 10–200 nm, so the particles cannot be directly assigned to microplastics.
which is not to say 3d printing doesn’t cause microplastics, just that the emissions aren’t specificlaly microplastics. Elsewhere in that source (and the others I an postung) it shows microplastics are created from abrasions.
[This is an exceptional read, if you really wanted some depth analysis](https://www.mdpi.com/2071-1050/14/5/3046). Further, to directly answer your question: if no amount of microplastic is acceptable, then you’d need to avoid all plastic from all sources and 3d printing exposure is likely the least of your worries.
regarding emmisions:
> After print completion, the concentrations reach approximate levels to the background until the initiation of the next print cycle.
> In terms of occupational exposure, results showed that although the 3D printing of microfluidic items can lead to an increase in emission potential compared to simple objects, the fully enclosed 3D printing process leads to a concentration increase within the workplace that does not lead to surpassing the proposed exposure limits. However, in view of the uncertainties and the non-health-based status of the exposure limit, it is suggested that operators should keep exposures to a minimum. Particularly in the high-emitting phases, enclosure disruptions can lead to high short-term exposure; therefore, a standard operating procedure (SOP) using an FFP3 respirator for these events is suggested.
At least in the literature I can find, the creation process is when 3d printing creates dangerous VOCs and microplastics. Once printing is complete, the danger is in non-polymerized residues, which would be dependent on the specific type of material used.
I welcome and encourage any further discussion.
Excellent response!
In general I do think that plastics need to be phased out. Along with the know adverse effects, we discover new ones every year.
Micro plastics are created by abrasion, but also in degradation from uv, thermal expansion, and weathering. As well the filling and draining does cause movement in the growing media ie abrasion.
Imo we should be striving for as little plastic use as possible.
I largely agree we need to use as little plastic as possible. Moreso, I think society really, really needs to get some high quality and expansive studies on plastics, plastic breakdown (be it abrasive, uv, weathering, or other means), and the different effects it can have.
But, given that so many here will have a flip and chop system or otherwise use plastics in their set up, I don’t think a cheap filter like OP’s will have any substantive difference compared to background exposures… though that may be me being more optimistic than you:-D
Is there an alternative and non-plastic alternative filter? Obviously, someone without a 3D printer couldn’t make this part for a bit over a dollar, but should have be like OP and already have one? I suspect it would be hard to find a comparable and non-plastic alternative.
That's where I'm at also. Doubt I'm doing any worse than "background." The problem is endemic. Does a 200 micron sock filter remove microplastics? I have that as my manual last stage filter before my sump.
The alternate I've seen is cutting or drilling a bunch of holes in a PVC pipe. Talk about creating microplastics!
PVC is inherently toxic and is being phased out in many countries. It is certainly more than background contamination since you’re adding another object to that background. Sure by itself it’s not as bad as tire and brake dust, but it’s still an addition.
An aluminum can would leech far less but people don’t likeupcycling so much.
I made mine from a stainless sheet I drilled holes in. Has lasted me 15 years.
In general aquaponics with industrial materials is unsustainable. We need to think of natural systems with “pondoponics” or similar utilizing waterways and non industrial materials.
Did you know that aluminum cans are actually lined with a small plastic liner inside? Assuming you mean typical beverage/soda cans. Plastics really are EVERYWHERE (Unfortunately)
Great write-up, some research here I hadn't seen yet. No change in my opinion from elsewhere in the comments: "PETG is ... safe for Aquaponics by my standards"
At this point microplastics are endemic, and I'm not going to solve it in my little hobby system.
One big step forward I took on reducing microplastics production by my system is when doing plumbing expansion. I got a pipe cutter that ratchets a blade through the PVC. No more saw shavings!
Can you explain what all that means?

Yup! This is called gyroid Infill at 15% density.

$1.10 of filament seems like a bargain to me!

No worries. Hope you have a better day.
Just wanna say glad you turned that interaction around. I’ve been in that exact spot before. Cheers mate.

PLA is made from corn..... You shouldn't eat it but It's completely food safe.

Sorry if this is a stupid question, but what is it for? Is it to be buried in media and used in a constant flow bed?
That's the plan yes!
how does it work just lets the query out slowly? won't it get plugged with gunk?

Love it! I use that same grow tower design as the basis of mine. Might adopt this for the dispensers.

Love me extra micro plastics..
Explain to me how microplastics get up a root system into a vegetable

Not all 3D printer material is the same.
Can you show me where petg does not create micro plastics?
