did you ever get that 3d printed screen for your ats? how is that ats doing?
Yes, it arrive a couple of days ago.
It's not for the current ATS (drop box 0.6) that I have. That has enough catch material (Epoxied Rough WHITE Gravel material). Plan is to improve this ATS by adding 1 or more LED's (since Algae kind of pack grows around the single LED), but not across the whole possible surface of the ATS (as light is blocked by first growth). But even as it is, the DropBox 0.6 is doing VERY GOOD with a nice weekly harvest (that would possibly be growing on my rocks)
The 3D screen is a 7x7" for the ATS I plan to DIY build. I ordered Red/BLUE led's from China and still waiting for those. The box I'll build out of scrap Acrylic I already have, and I plan to run it off my Return (from tank), or Return Pump (T-off to Tank).
So I don't have any honest, truly tested opinion of the 3D printed screen. I never made one myself, so this is the first screen I've ever touched.
I will say this. I got the single sided one (other side is smooth). The two side one is two singles glued back to back, but got one just to see if worth getting a 2nd one.
First impression is the rough side isn't what I expected. I'm no expert, and as I said I haven't tested. But it's not as rough or prickly as I expected. Kind of bumpy where the 3D (X and Y grid lines overlap).
Maybe it will be effective, but without testing I can't say. (If I run it across my cotton shirt it does catch (a bit) so maybe it will catch algae and also be easy to clean). But there are loops within each X and Y run, so those holes might be tough to clean, but maybe not needed to be clean (since good to leave some starter algae behind). Might be the reason this is a good screen.
The custom printed screen does have 3 enforced holes at top (like re-enforcements for 3 ring paper for binders). Made for rings to hang on water flow bar.
The screen does appear durable, flexible.
That's all I can honestly say at this point.
