v.redd.itConcentric infill first layer was a good choice! Makes a really cool pattern in the light.
128
Thanks, It turned out really nice. I like using concentric rather than lines because it makes the models have cool designs on the tops and bottoms
98
This is very important.
51
Sweet. Now just print this using a cintered metal 3D Printer with Inconel powder and you'll have some seriously tough shit.
71
I wish. That would be some tough shit, as you said
25
I'm going to see if I can get this in ti/AL at work. Totally bet the guys would print this to show off.
20
That would be great, it's a great showcase of what 3d printers can do. There is a small version on the thingiverse page that's 3x3 tiles, I printed that out as a test before the big one which is 15x15
9
You can get carbon fibre filament that's meant to be pretty strong
3
I’ve got some it is gimmicky. Just has some fibers mixed in so it’s really just PLA strong. It doesn’t flex as much, but for armor it’s about strength..
So this it goes: PLA<PETG<AbS<Nylon I believe
6
Ya thats nice, i'm looking at copper pla for other projects. Can't wait to try metal
5
Could also try to get your hands on a graphene based nano composite filament i think I read an article about those somewhere...
1
That's a lot buzzwords that doesn't mean much. Besides, having nanomaterials in your moving print is probably a bad idea.
8
Huh didn't know that thanks for the clarification!
1
gotta dig up the video, but I worked at a company where we had access to a titanium printer - definitely had some demo prints of titanium chainmail sitting around.
3
Medieval NASA?
47
That's what I thought lol, but watch the video on the thingiverse page it shows the real version of this chainmail. It's printed in metal so it would be very strong. NASA said they would use a scaled down version inside space suits. (The one I printed is larger than the original)
59
Space jousts?
56
Space jousts, coust to coust.
22
I have named my printer Moltar.
4
In the high dessert.
2
I’d watch that
15
With ostriches
22
Sorry if this is a noob question but how did you print the larger one since the one on thingiverse is only a small square
4
I guess you tell the slicer that you want multiple copies, and place them close enough that the loops interlock.
6
When you download the file from thingiverse there are different sizes, there's 1 small square link, then there's a 3x3, 8x8, 10x10, 12x12, and the one I made which is 15x15
3
There are several different models on the thingiverse link

Wow, why did it take 98 hours? It looks like it's only a centimeter high
20
It's a really complex shape and it's small so it's not really layers, but rather like little dots built up. You need retraction as well so a lot of that adds time and the very slow speed is why it took 98 hours
36
How many grams of filament was it?
11
It's about 48 grams and 16.24 meters of filament
20
I feel like that is the longest time to print 48 grams I've ever seen. Haha.

I think the design is really awesome, but for the reasons you have mentioned, the design is better suited for a metal or SLA printer. Something that moves photons around instead of a print head.
1
Did you scale it down from the link you posted? I really wanna print this now.
1
nope, I didn't scale it at all
1
If your gonna make one start with just printing 1 link and set your printer up to stop stringing, then go to whatever size you want
1
Ah alright I've already printed the 3x3 now in 30 minutes, feels so great! Came out perfect too. Slicing the biggest one right now! 15 hours to print :D
1
It was probably sliced in a way that includes a billion retractions
18
That looks super cool! Is the entire thing printed at once? Or are all the little pieces assembled after printing?
10
I have another post on my profile of when it was printing, it's all one piece no assembly, but it took some time to get off the glass bed
10
Ah ok. Oof, I don’t envy you, I imagine that required some careful patience!
4
How the heck did you remove it from the bed?
10
With a razor blade, I popped each tile off the bed. Took like 30 minutes
17
If you plan on making more, try throwing the glass into the freezer. The pieces should slide right off.
12
If you throw the glass into the freeze you probably have more time added for cleaning up the shards. not to mention having to get a new glass for other prints. /s
0
Wonder if it would've been better to just use tape and then peel it up
3
Possibly but the thing is a lot of the time tape gets really embedded in the first layer and it takes a lot of time to scrape off. Also you wouldn't get that pretty shine that you get with the glass bed. It probably still would have been easier if he says it took like 30 minutes though.
5
Oh good point
1
Can you add extra pieces together?
8
Not easily, or quickly.
7
Oof..
5
Ya you could, but it would probably be really hard
4
Maybe you could print a row with some open loops to hook into the larger piece, then melt them shut, maybe with a 3D pen or a hot knife.
Or have a different design with closeable loops to act as a seam between larger pieces.
4
That's a pretty good idea too
1
Maybe melting the things together. But that means a section that don't articulate
3
You could always use lots of tiny zip ties. Something like this.
3
Overlap and rivet.
2
How did you removed these supports?
8
Its actually printed without supports. Pretty amazing, it looks like it wouldn't be able to do it, but it's does great, there some stringing with it though
9
now make it smaller and more of them!
6
I made a small one that's 3x3 tiles for a test run,. Now I'm gonna try to scale it down and see how small I can make it
7
what printer are you running?
3
It's a ender 3 v2. Not stock, I've done some mods/upgrades
3
im very much looking forward to getting an ender 3 v2 and get an ender extender kit, ive wanted to do large 3d printed stuff for a while now and most of it is DnD related
3
That printer is a beast for the price.
1
Was the print 98 hours long or was it 98 hours long in total with planning and failed prints.
5
98 hours to print. This was the first try except for 1 smaller test version
4
O my
4
Would like to see this in PC filament and stress tested.
4
That would be really interesting. Check out the video in the thingiverse page link I posted, it shows the real version of this chainmail, printed in metal and carbon fiber
2
Get a resin 3d printer and it will take just an hour to finish the whole thing
4
I've looked into Sla printers they are really cool, my brother has one, but I can't use one in my small apartment, I have animals and the fumes would be strong for them
9
Sure, resin printers are neat, but they're absolutely terrible for the environment. The world simply doesn't need hobbyists creating toxic waste
4
And plus, there are ways to reclaim filament from FDM printed parts that are no longer used, since the plastic can be re-melted, even into be filament. That and PLA is biodegradable. AFAIK you can't do either with resin.
To add to what you said, resin printers have their applications, but the hobbyist that prints, and prototypes, and throws away old models, should certainly stick to biodegradable filaments, like pla, or should set aside old FDM printing waste and get it reclaimed (or, if you print enough, get yourself a filament extruder, you could end up saving money in the long run)
I saw people talking about how the landfills are gonna be full of shitty resin knick-knacks thousands of years down the line, because of all off the "small businesses" and "resin artists" that sell it, and pass it off as okay because they're a small business, and therefore cannot hurt the environment. I feel like hobbyists with SLA printers are gonna contribute to the problem as well, given that most people print little knick-knacks they think are neat, and will eventually end up in landfills.
6
Yep. The one and only reason I got into 3D printing was because PLA is biodegradable (I print exclusively with it). I want to have fun in my hobby but I don’t want to contribute to the world’s waste problems unnecessarily
6
Yeah, I set aside all of my scraps because me and some friends are planning on making/buying a filament extruder so we can reclaim filament. I might buy a roll of petg for prints that aren't practical with pla, but im gonna make sure i set them aside for eventual re-use.
3
I mean, PLA is biodegradable yes, but only in industrial composting plants. If you actually save up your PLA and get it recycled at the proper places, good for you, but I don't think most hobbyists actually do that. That said, resin is still worse, but PLA is not as environmentally friendly as you might think
5
That's a really good point you made there. I have almost 100% of all my used filament/failed prints in a bag to recycle one day. SLA is very important, but it needs to be safer for in house use and the environment
1
Thank you, I didn’t know this existed but just read the article.
3
No problem, my hope was someone would find this interesting
2
That truly looks like Thor's armor from the MCU.
Well done!
3
Wow! didn't even think of that until now. It really does
1
Beautiful.
2
Thanks for the reward!
2
did you print it as a whole?
2
Yep, one print with no assembly
3
and 96 hours for that one print?
2
No shit
3
TIL NASA makes chainmail
2
Now print a suit.
2
I might do that
1
Here's the file on thingiverse. there is a video about the real NASA chainmail on the page too https://www.thingiverse.com/thing:2437081
The design is really slick. It mimics scale mail with the flat surfaces.
I didn't design it, all credit goes to the thingiverse link, but thanks anyways!
What printer did you use?
Ender 3 v2, with some mods and upgrades
Someone needs to set some of this up on a belt (CR-30/Blackbelt/equiv) printer and print an absurdly long sheet of it
That would be crazy lol
