You gotta keep in mind that you don't know how many of the people in the hobby are twelve. Once upon a time there was a column in Pro Sound News called "the cranky old sound mixer" which was some nameless flinty asshole who basically shit on every trend. he was right more often than he was wrong. One need only search "orcs with tits" in Hubski to get my general opinion on the 3d printing community. That was before I got a cheez whiz printer; I will know also refer to "knitting for dudes." My wife and I agree that "maker" is one of the dirtiest words the millennials ever coined. It's their way of saying "dilettante, but make it aspirational." You have to be exceptionally stupid to have a printer catch fire. Not that there aren't a lot of exceptionally stupid people out there but! PLA extrudes at like 220 degrees. Water boils at like 212. You have to have reached new heights of stupidity if your melty process involves combustion-grade temperatures. And yeah - you probably don't like the smell. Those of us who grew up building plastic models can tell you that what you're smelling is orders of magnitude more benign than we used to put up with just opening up a plastic pack of Tamiya, heaven forfend if you were stretching sprue to make antenna wire. It's just fucking polystyrene and that's the shit everyone thinks is toxic. There was a time when you bought a Prusa and were fucking done with it. Me? I bought a Prusa and was fucking done with it. I bought a Prusa because every camera house in LA prints their shit on a Prusa, and their shit is thrown into a box with $200k worth of glass and hauled out to the desert where it is not allowed to break. then everyone bought Bambu because all their talk about independence and makers and shit was a total fucking lie, they were all about the bottom line and they didn't give a single fuck that it all went through Chinese servers. And when all their printers turned on in the middle of the night and crashed they got what they deserved. Now everyone's all "zomg can Prusa ever catch up" because none of them print for any duration or any real use. It's all shit their wives don't want or need but can be justified by making low-poly napkin rings or some shit. Yeah and see if I sent a TPS report to my Epson and needed to soak it in a bag of nail polish before I could give it to my boss I wouldn't say nice things about Epson. "but I made it!" no one gives a fuck, Chad. "Makers" have been trying to make "3d-printed X" cool for fifteen fucking years now, fucking give up. It's a tool for rapid prototyping. I use it for rapid prototyping. You run into this with the jewelry community. "I spent over four hours piercing this piece with a jeweler's saw!" Great! You should probably be paying yourself about $70 an hour for survivability, can you sell that thing for $300? No? Well than let's call your hobby what it is then, shall we? Buddy of mine bought a skookum laser. He's making dog tags. He's got 'em down to 45 minutes of burn time each! yay! Except he accepted a contract for 100 of them which means he's looking at the better part of two work weeks sitting there swapping pieces out like a Vietnamese sweatshop. If that's really where you want your hobby to be, good on ya but as business models go, yours sucks. I wrote this over ten years ago. The difference between now and then is I'm probably 18,000 hours into 3d printing, two different kinds. Oh, and bulk ABS has come down by a factor of 3. TWO OTHER FUN FACTS FOR THE 3D PRINTED AVIATION COMMUNITY 1) There is no difference from a compression/tension/deformation standpoint between 25% infill and 100% infill. Carnegie Mellon ran the numbers you can look them up. I print nearly everything at 10% with 2-3 shells, gyroid fill. If it's a bracket that requires screwing things into it I run 25% gyroid with like 5 shells, which gives you enough material that you can print threads and tap. Which isn't nearly as strong as using threaded inserts but threaded inserts also like having 3-5 shells to gloop into. 2) you can make damn near anything fly through sheer power to weight BUT, that seems part of the fun.
