Good rule of thumb for a bare minimum, if you pick machinery up with one hand and think "Ooh, that's got some heft to it!", Then it should be treated as heavy machinery. Motors really don't need to be that big anymore to be able to cause significant damage.

[@BaldMancTwat]

@@superme63 To be fair, I don't think there's that many people taking the safety of smaller motors for granted. I think most people know if they tried to drill/sand/saw themselves, it would work and hurt a lot. To be honest I'm surprised that staplers don't have more warnings on them. I guess they aren't exactly gonna cause a serious injury but I have to say, stapling myself by accident was the worst pain I ever endured.

[@someoneinthecrowd4313]

Yeah, when I was 19 and started working at a factory my boss just told me to get in the forklift, showed me what the different paddles did, and then made me lift a couple tons and drive it around, and putting it into storage some 10 feet up in the air etc. I have experienced dropping several tons worth of shit, like one time I was carrying something that was in a pallet and a little bit off center on the gravity, and I was driving around in the outside area of the factory and drove over a pothole with the tiny ass left wheel and I watched as all the shit slid off in slow motion. That's some serious disfigurement or death if anyone was around, I knew the pothole was there too but it was in a moment of inattention.

Resin actually gets stuck into hollow parts if they don't have holes! Kinda like how you can dip the neck of a full bottle in water and it doesn't empty, parts without holes can't empty while printing. So printing a hollow ball would end up being full with uncured resin and be a paintball lol

They definitely still do the pledge, at least in more rural areas, not sure about urban and suburban areas. I live in a really small town (dub 10k) and substitute taught for a year in waiting to go to grad school and every day the intercom came on with morning announcements and everything, and the last thing they said was 'teachers remember to lead your students in the pledge and have a great day. Don't know if we necessarily have to, and the students definitely don't have to follow along if they don't want to, but it's definitely expected of teachers and students alike.

[@vaughnvarma8447]

my 2 cents about resin printing: it takes so long mostly because it has to peel each layer off the bottom of the print bed. On my resin printer, each layer can take something like 8 seconds to 'cure' (enough for it to keep its shape during the next part), but between every single layer, it needs to pull the entire part up off the bottom of the vat, and then move it back down to the appropriate layer height. This process takes around as long as the cure time, and if it were not needed, you could get away with shorter cure times, as there would be way less mechanical forces the part would need to resist between layers. There have been some attempts to work around this, with mixed results. One simple solution is to use a top down printer, where the light is shining on the resin from above, but this requires either a ton of resin to sit in the vat at all times, or some secondary liquid that is denser than the resin, and won't mix, and this also can cause other issues, like the resin being too viscous to cover the entire print every layer, before the curing begins. Another solution I've seen uses pressurized air, and an oxygen-permeable membrane, which creates a boundary layer at the bottom of the vat where the resin doesn't actually cure, and then you can actually just pull the print out of the vat as it cures. I remember this having its own set of issues, maybe around controlling the thickness of that boundary layer, and the general added complexity from all the new tech in there. It may or may not have also needed a special resin to produce that effect with oxygen.

[@phillipmaciejewski9872]

Probably answered already in the comments, but the reason you shouldn't leave uncured resin in models is when you leave uncured resin trapped inside models, it tends to cause the models to crack- I can't remember quite why but it might have to do with the fact that resin expands slightly when it cures (which is why you have to account for that expansion if you want to make good ball joints or push fit parts) and I think the resin on the inside will slowly cure and then the expansive pressure cracks models. Having to add drain holes is another obnoxious part of resin printing, because unless you can miraculously place that drain hole where it isn't visible at all, you have to then fill and smooth the drain hole to look flush with the surface, or match a given texture that the drain hole goes through. There's also an issue from printing entirely solid things, and why you need to hollow- a similar thing happens with the model or what have you eventually cracking, but I've only noticed this with excessively t h i c c model parts, and I think the reason is that the deep inner parts cure at a different rate, leading to uneven cure and curing of the internals over time when the outer layers are already cured. I've printed some beefy stuff before without issue, its mostly just a waste of resin. That being said, I've had models that I included drain holes on and (mostly) properly drained that did end up cracking too- but I think that may have been overexposure from being unprimed and sitting in front of a window. Overexposure causes the resin to go brittle and shatter easily, which can lead to cock-ups during/after curing when thinner parts get overexposed making them easy to break- compounding this fact is that those thing parts are usually very snagging or jutting shapes, like swords, arrows, spikes, etc which are easily caught. Its why people recommend shifting around your parts during curing to ensure even curing but also minimal curing comparatively on those thin bits. I printed an ant once and all the legs ended up breaking off in a few days because they were so overexposed compared to the body, which took awhile.

I work at a place that 3D prints in metal! I print in CoCr using a EOS M270. It's around 15 years old but it does the job. It uses a laser to heat metal powder.

[@sir_vix]

Does it use selective laser sintering (SLS), or something else? How does the material condition compare to traditional methods? I've heard that there are some laser hardening processes now being used on engine components for the F35. (edit: oh I just re-read the bottom sentence, you answered my first question already...)

[@beastoffate]

I'm pretty sure the issue with metal 3D printing is that they use lasers for precision to fuse the metal and in order to achieve a powerful enough laser, you need higher voltage at a consistent rate, without compromising amp draw.

on hollow resin prints: yes, there are cases when you hollow out an object and resin gets stuck inside, it is bad for the model and in most cases will lead to cracks in the model, from which the trapped resin will come out and get on stuff, to print proper hollowed resin models you need to add holes to it through which resin can flow out and air in

I used to work with DMLS printers, and the issues that would probably prevent consumer adoption is just the sheer amount of special equipment needed to do it safely. We had an industrial sieves to clear spatter from the good powder leftover from the print, we had special vacuums full of a concoction to pull powder out of the machine, you need a band saw to remove the print from the plate, you need a CNC machine to level your plate, etc etc... All of this while wearing respirators and going through hundreds of gloves. Plus they produce a massive amount of heat while in use. I hope they reach consumer level, but I'm not sure it will happen soon

The phrase you're looking for is "economy of scale." Per-unit costs get lower when you increase capacity in part because your sunk costs are distributed over a broader revenue base. You don't want to build a factory to build just one unit unless your customer is willing to pay out the wazoo for that one unit.

Talking about people wanting to buy stuff from you that you made and way low-balling on the price: I had a friend recently ask me to print a 6 FOOT statue. I told him at least $1000 and he hasn't talked to me since lmao. To give you some context: my print area is roughly 7x7x11 inches. To print that volume takes roughly 100 hours, printing at good quality. Now scale that up to 6x3x3 feet. 6 x 3 x 3 is 54 cubic feet, but since it's a statue and not a solid chunk of plastic, some of that is going to be empty, so let's round down to 48 cubic feet. 48 cubic feet is 82944 cubic inches. My printer can print in 539 cubic inch chunks. It would take roughly 153.88 individual print jobs to print the entire volume of the statue. Times that by 100 hours each and we're looking that somewhere in the ballpark of 15388 hours of print time, or 641 days. Now you might say: "Justin, you could just not print out the chunks on the inside that are just perfectly square rectangular cubes." And you'd be right. But even assuming a reduction of half print time, we're still looking at 320.5 days of solid printing. This is an astronomical amount of time for me to be printing one project. That's TEN MONTHS of printing. Trying to factor in just the cost of my time would go way, way above $1000, not to mention the filament cost. Assuming it takes 80% of a roll of filament to print each 539 cubic inch chunk, and assuming half of 153.88 print jobs (because we can ignore the blank rectangular cubes on the inside), and each roll costs roughly $20, we're looking at roughly $1538.80 JUST FOR FILAMENT. In all honesty, I should have quoted him waaaaaaaaaaaaay high than $1000. Not to mention the endless sanding, gluing, and reprinting (because parts don't always come out right on the first go), I should have quoted closer to $10000. I think I low-balled myself.

You have a lot of thermal cycling that leads to microstructure-level properties we don't understand fully yet which makes it hazardous to use beyond prototyping phases in many cases. Of course, that is a very superficial explanation and the issues with it are very complicated... definetly look into it! It's a super cool field.

o yea i bet it wreaks havoc on the crystalline structure haha.. probbaly turn to powder under stress :D would it be possible to temper/sinter it or something?

[@jackfrost1989]

My method of getting resin supports off involves running it under hot water after letting it soak in IPA then just ripping it off (if its thin stuff then use cutters.). I also use Lychee slicer pro and the island detector set to real. it is paid which sucks but its suuuper worth it.

You NEED to get a Formlabs laser resin 3D printer William. The auto supports in their program is like magic, full auto supports work perfectly 99% of the time. They also automate the wash and cure end so 1 pair of gloves is all you need. They also have flexible resins to simulate silicone and tpu. Once you go Formlabs you never go back to cheap lcd resin printers

I'm already seeing William making like, a podcast with left and right audio, and then counting the podcast as two.

[@alsodan]

I enjoyed this podcast. Carry on.

i think i unlocked an additional % of my brain listening to the split LR audio feed bit

[@Magmafrost13]

The split audio works surprisingly well for being able to understand both conversations at once, but for probably-autism-related reasons, different audio in different ears is absolute torture for me.

[@RickSanchez-st3mj]

much as i love nigel having alex on the podcast is such a joy, and emily is such a good guest. i hope going forward they can all join in and have more chaotic discussions.

I noticed some of those weird extra supports cura made on the outside that do nothing went away after updating to cura 5.

Not only do metal 3d printers exist, but they're commercially viable too. They work by having a thin bed of metal powder atop a plate, and a laser melts the shape of the current layer of the print, then another thin layer of powder is spread over the bed, and repeat. We use 3d printers to make steel parts at my place of work

For your "most kids killed of all time" question, I did a stupid amount of reading out of my own curiosity. It's complicated to answer, but per the most in-depth researchers on the topic roughly 50% of most war's casualties are civilians, in every century. Based on that, the sloppy estimate is: 1. China - 78 million (they're *huge* and have been around for thousands of years) 2. USSR - 55 mil 3. Nazi Germany - 21 mil 4. Mongolia - 20 mil 5. Spain - 16.5 mil (Genocide on the Inca, Aztec and Mayans, plus 750 years of Reconquista wars) 6. Japan - 15 mil (Almost entirely from their Chinese genocide during WW2)

[@TheGrumbliestPuppy]

I was surprised America and the UK weren't higher on the list, seeing as how brutal our imperial colonialist periods were, but WW2 tips the scales on the entirety of human history in a crazy way. A large part of this is that antibiotics, vaccines and industrial farming made the global population exponentially grow leading up to WW2, meaning there were simply *way* more humans around to kill than ever before.

I just graduated, they still do the pledge every day, but a lot of kids in hs choose not to, and its not forced or talked about.
