no FDM printer is safe from “toxic mold” that builds up between layers.
This is why we seal ceramic cups, you can find this info online.
I love the design it looks cool AF.
unfortunately it’s just suckin fumes (proxy exit hole is air that’s at temp), potential mold and microplastics.
funny we don’t see more 3d printed cups…….
after the first time you use it it’s basically a toss.
:( you keep deleting this comment but I won’t stop posting my friend 💕
love the idea but gotta keep the 3d printing and smoking community safe.
you need to read the actual study done by a university. That contradicts and says this is not factual. just because you read something on the internet doesn't make it true.
I'm not going to read this as it's not from a credit able source. I am a plastics engineer. if designed. it should cause no more harm than smoking already causes. the layer lines crap your talking about yes that can happen but simply washing fixes that.
