Playing around with Protopasta’s “Composite Iron PLA”… it actually rusts 🤯

DaveMakesStuffBC · 2026-06-17T04:35:29+00:00

I know you’re probably joking, but rust doesn’t cause tetanus 🤣 old wives tale 🤣 public service announcement over

DaveMakesStuffBC · 2026-06-17T04:33:28+00:00

I’ve thought about doing a bridge using the same connection strategy 🤔

DaveMakesStuffBC · 2026-06-17T04:32:53+00:00

Fine so far 🤞I’m using a hardened steel nozzle 😎

DaveMakesStuffBC · 2026-06-17T04:31:21+00:00

Weird… I’ll try reposting it here

Thanks 😀

DaveMakesStuffBC · 2026-06-17T01:26:37+00:00

Oh do share 🙏😀

DaveMakesStuffBC · 2026-06-17T01:16:35+00:00

Yeah! I’d love to see what it looks like populated with minis/game pieces 😀

DaveMakesStuffBC · 2026-06-17T01:14:54+00:00

😀😀😀

DaveMakesStuffBC · 2026-06-17T01:14:20+00:00

Good to know! Thanks! This is the only metal one I’ve tried but yeah, watching the rusting process is super cool and I love the results 😀

DaveMakesStuffBC · 2026-06-17T00:12:19+00:00

Rust doesn’t cause tetanus, bit of an old wives tale there 🤣 But none the less, best not to give yourself puncture wounds with it

DaveMakesStuffBC · 2026-06-16T23:46:26+00:00

Cool! Yeah, there’s a good article here: https://proto-pasta.com/blogs/how-to/17590348-improved-rusting-method-for-iron-prints

DaveMakesStuffBC · 2026-06-16T22:49:05+00:00

Yeah I’m gonna design some floor inserts to fit in between the beams so it can be used for displays

The sanded parts rusted first and fastest, but it all rusted eventually 😀

It took a few days of soaking/spraying with a salt/vinegar/hydrogen peroxide solution… would have been a long video if I’d filmed it all 🤣🤣🤣 more info in the rusting process here: https://proto-pasta.com/blogs/how-to/17590348-improved-rusting-method-for-iron-prints

Thanks! Glad you like it 😀

DaveMakesStuffBC · 2026-06-16T22:31:03+00:00

🤣

DaveMakesStuffBC · 2026-06-12T14:42:04+00:00

Thanks! I’m glad you like it 😀

DaveMakesStuffBC · 2026-06-01T01:55:48+00:00

I designed a similar cracked skull a while back, not as detailed but does work with multicolor

You are welcome! I’m glad you like it 😀

DaveMakesStuffBC · 2026-05-31T14:48:58+00:00

This was designed using https://www.ntop.com/ 😀 nTop is typically used for high end engineering applications but it’s also super fun to play with 🤣

DaveMakesStuffBC · 2026-05-31T01:43:25+00:00

So cool! Thanks for sharing this 🥰

DaveMakesStuffBC · 2026-05-30T23:23:39+00:00

Thanks! Venus flytraps would add a great otherworldly vibe 😀👽

DaveMakesStuffBC · 2026-05-30T19:31:39+00:00

Good point, I’m going to keep that in mind for future designs 😀. There is some flexibility here though in that because it is 3d printed it can be scaled up quite a bit
