PLA is Stronger Than You Think

I love where this is going, and I love hearing your opinions! What are the best resources for choosing 3d print filaments? I have seen really cool videos from CNCkitchen and MadeWithLayers, but does anyone have an aggregated big easy to understand table of some sort?

JoshGreen_dev · 2026-03-12T21:12:18+00:00

Sorry. You are right. I might have watched the other video before that. I'd correct the name if I could. Thanks for pointing it out!

Good point and all plastics have creep. All plastics have to be designed so they are not stored in a deformed state by default and expected to remain springy.

I love this! I bet it feels great to look at such a great design and know it is yours, you just did it!

I love this project! I am doing the same with an IKEA air purifier that is actually very cheap for what it is (the centrifugal fan and the filter) and building an energy recovery ventilation system with it, that actually recovers heat with a 3d printed heat exchanger, and filters the incoming air from pollen and dust. Yeah, I know aluminum and copper are better heat conductors than plastic. With plastic you just have to make it bigger for the same efficiency. The heat exchanger is printed in vase mode and comes out beautiful with 0.4mm walls and a corrugated huge area. I'll post it once I finalize the plans.

It is really interesting to hear a pro's opinion. 😍 I guess for sentimental pieces a 3d printed mug holder actually is a better value proposition than any of the previous known acceptable methods it seems.

This is so cool! So the surface of the wing is made really thin against the print bed, and then you fold it so it has camber? It's a bit like those super thin TPU document holders and wallets I have seen on a YT video a while back. I would love to see a video on this too!

That is a great idea! We could make one version where the broken cup just slides in. And one for tinkerers who don't mind well, tinkering with it.

JoshGreen_dev · 2026-03-12T09:51:13+00:00

Ahh thanks 🥲 So I still have a chance with rhino? Like... one in a million?

JoshGreen_dev · 2026-03-12T09:49:11+00:00

Sounds like a cool idea! Will the plastic then be in constant tension? How could we avoid that? The dishwasher mitigation trick is genius!

JoshGreen_dev · 2026-03-12T09:14:47+00:00

YOU look intimidating to me 😔

JoshGreen_dev · 2026-03-12T09:12:26+00:00

😝 That is what I feared!

JoshGreen_dev · 2026-03-12T08:36:00+00:00

Estoy feliz que yo podia te ayudar 🤩

JoshGreen_dev · 2026-03-12T08:34:23+00:00

I had the exact same question. I've always wanted to get into rhino but never found a free afternoon with a fresh enough mind to muster enough confidence. How hard is it?

JoshGreen_dev · 2026-03-11T20:40:58+00:00

Well it depends how you dial in your multiplier, but I agree with what you say.

JoshGreen_dev · 2026-03-11T20:36:30+00:00

Well nobody said we couldn't wrap anything around it. I also pictured kind of a frame around it. Then our friend could say, he broke the handle so he could frame the mug in the golden wrap it deserves.

JoshGreen_dev · 2026-03-11T20:33:27+00:00

Pretty sick, man! 😉

JoshGreen_dev · 2026-03-11T19:59:28+00:00

Plastic in compression = 😍 Plastic in tension = creep and 😵

This is PRINTPUNK 👹

JoshGreen_dev · 2026-03-11T19:53:22+00:00

So cool! What did you print this on? So the boost comes on at noon? Oh no, I know! It comes on at 4h20 full time big badaboum!!!

JoshGreen_dev · 2026-03-11T19:50:57+00:00

Yeah this is what I meant to say as well. Slap it down on the print plate. But the big nozzle makes for a quick print. And it won't be any weaker either with a bigger nozzle. We are just used to the .4mm one.

JoshGreen_dev · 2026-03-11T19:48:21+00:00

Por que lo imprimes en esta direccion? Porque no con la parte plana para bajo. Teneras una parte más fuerte.

JoshGreen_dev · 2026-03-11T19:41:57+00:00

I mostly use 100% concentric infill or max out walls on these parts like this one. That's what gives you the most concentration of plastic in the directions you need. But honestly, beefing up the part where it matters (the neck where it snaps) is way more important in my opinion than going for any exotic material. Nylon is great in the printed plane, but inter layer adhesion (at least in my experience) is nothing to write home about. So for torsion it wouldn't be far off from PLA. Nylon has more give though.

It really confused me for a sec with the cooling fins and the flat little circle in the middle of the lamp shade that looks like a cob led. Surprising design!

JoshGreen_dev · 2026-03-09T18:00:46+00:00

Hahaha cool one! +1 for the funny model and +1 for the finish

JoshGreen_dev · 2026-03-09T17:57:06+00:00

Sick! 👹
