@Vixen too subtle for @Polygeekery, I think.

You're looking to set your 3D printer up in your neighbor's Garage (the same neighbor that keeps borrowing your tools and not returning them)
A couple of years ago he went out for milk and never returned. I cannot speak as to whether or not he may have ended up in a swampy area where no one dare tread.

@Polygeekery
Risky ... Before you know it Swampy has it on video and long filenamed

So I ended up buying a Creality Ender 3 Pro. It seems like everything I want to print takes 24-72 hours (due to size, needing large amounts of infill and high perimeter counts). I can see how a person would easily end up with multiple 3D printers.
-
@Polygeekery This may be a stupid suggestion, but instead of 3d printing the in-fill, could you print it hollow and then fill it with something else?
-
@hungrier Depends on the shape and the required strength of the final part. Some prints (at least with my printer) are impossible without infill because it'll collapse during printing.
If strength doesn't matter, I use 15% infill which is usually pretty weak but holds things together during printing. If strength does matter, I've found that parts become virtually indestructible by around 65% infill when using ABS.
I'm about to do some experimentation with Wood's metal. It melts at a lower temperature than ABS, so I should be able to use it to make weighted parts and/or even do metal casts with ABS molds. No idea what kind of strength a Wood's metal infill would do.

This is done sometimes, depending on use of part, but is not applicable to what I am wanting to do. Some people will print a part with minimal infill and an open top or bottom and then backfill it with epoxy or some other material. That would not work for my use case though.
You can also 3D print a part, take a mold of it and then cast it with some other material. Lots of ways to skin this particular cat, but high resolution and high strength are what I need for this project so it just takes a while.

A quick Google indicates it should be comparable to plastics such as nylon and HDPE. However, it contains lead and cadmium, both of which are highly toxic.
Wood's metal is toxic because it contains lead and cadmium, and contamination of bare skin is considered harmful. Vapour from cadmium-containing alloys is also known to pose a danger to humans. Cadmium poisoning carries the risk of cancer, anosmia (loss of sense of smell), and damage to the liver, kidneys, nerves, bones, and respiratory system. Field's metal is a non-toxic alternative.
The dust may form flammable mixtures with air.

This will be my primary use for a printer, if and when I ever get one (and a place I can do metal casting — apartments tend to frown on extreme fire hazards in your living room).
-
@HardwareGeek I don't plan to cast anything with Wood's Metal, I'd probably use Rose's Metal for that if it works without melting ABS. But I think it would be safe enough to use as a filler that's relatively contained inside the print, especially if I do something to seal it afterwards.

Sure, in the Dwarf Fortress sense. I'd say for every day I get a decent print, there's another four days of adjustments and repairs and cursing. I finally just got my printer working again after about three months of downtime due to issues that resulted in me replacing the motherboard, about half the hotend, several fans, and dremeling out a bigger hole on the power supply so it can accept a standard 120mm computer case fan.

Huh? My printer prints fine pretty much every day. The only times it's offline is when I purposefully change something and break it (like for example changing hotend enclosure and all fans - this took like 3 days).
dremeling out a bigger hole on the power supply so it can accept a standard 120mm computer case fan.
Probably printing new power supply cover would be easier and less messy.

So...small affordable electric foundries are a thing. I've definitely wanted to get into sand casting or lost PLA casting to convert 3D printed parts to aluminum or brass, and it looks far more affordable than I expected.

You could build the furnace yourself. I've seen it done on the Youtube channels Cody's Lab and King of Random.
-
@mikehurley That's what led me to this. A friend of mine has been "building" a propane furnace for going on two years now, and he never gets it completed. But this one just plugs into a wall and should be ready to go and probably costs less, too (my friend is spending a lot on the refractory cement for his).
I think his propane one will be larger (if he ever finishes it). But something this size ought to complement my 3D printer pretty well.
-
@mott555 the quetion really is I think is your friend building the foundry for the foundry or for the project? because that changes the math rather dramatically....
-
@Vixen He wants to get into sand casting, and he also wants to do some 3D prints with my printer for that, so our goals are similar. But he's just too ADD to finish anything he starts.

@MrL Indeed. My Prusa Mark3S will happily print everything I throw at it with minimal intervention or supervision. The wonders of automatic bed leveling - I even was able to use Octoprint's bed level visualizer and some custom springs to reduce the level variance even further. I think I have a sub0.01 mm variance over the whole bed.

Yay, got all that addressed and now I can't print because the power cable to the bed heater has snapped.

So it was a cracked lead-free solder joint. I love lead-free solder. Got that patched up, and then the glass build plate chipped out.

You're making this shit up, aren't you?

@MrL I wish. No, technology in general just doesn't get along with me. It's like I have a magical aura that causes nearby tech to fail.
-
I forgot the best one. This took forever to figure out. I kept having tons and tons of failed prints. The printer would just stop mid-print and OctoPi would lose connection to it. Finally, I realized that any time I turn the ceiling fan on or off, it crashes the printer. Some kind of EMI thing I guess.

It happened to me once. My housekeeper turned some device on, that probably caused some fluctuation in the network and Pi lost connection.

So, you're the one responsible for the F-35?
-
@Zerosquare I'm about eleventy-billion layers removed from actual aircraft, though I have been involved in equipment related to the B-2. But I do believe we (my company, not necessarily me personally) are about to begin work on some new flight test boxes for the F-35.

Alright, next 3D printing experiment: I have a pound of Wood's metal. I'm going to print a simple ABS mold as a test. I'm going to melt the Wood's metal and pour some of it into the mold, and if all goes well it will A) not light the mold on fire and burn down my apartment, and B) not cause me to die of cadmium poisoning.
This should be fun!

Mixed results. I made a small mold for a 1-cm half sphere. Molten Wood's metal does not appear to deform ABS at all. However, I cannot free the cast metal part from the mold. So I can definitely use this alloy as a filler material to make weighted parts, which is what I wanted to test for my next project that needs a bit of extra mass for stability. But it bonds to the plastic too well to free it, so I can't make cast parts with it, which is fine because I'd never want to use Wood's metal for that anyway since it's a bit toxic. I'm going to have to melt it out to recover it.

OctoPi is pretty awesome.
And I just ordered another 3D printer. My queue is too long. A month ago I was fine with no 3D printer, now I "need" multiple ones.
I may get a third. The Monoprice Delta printers are too cool to not have one.
-
@Polygeekery I have the Monoprice Maker Select V2 which is a rebadged Wanhao i3 which is a Chinese implementation of one of the open source Prusa i3 models.
-
@mott555 for some reason I thought you had an A8. Especially after you said the cables came off the bed.
Check Thingiverse (if it is working, their devs are as competent as...... actually I don't know of any other site that is as incompetent as theirs) to see if there is a way to reinforce it and take off the stress of that joint.

Once you have two you can print the third one in half the time

Except for its math skills. Check out the approximate total print time as compared to print time so far and print time remaining.
It seems to stem from another fluke that says all prints are at least 100 layers in height. I think somewhere along the way it rounds layer counts to the next highest 100. My slicer inserts M117 information, which it is supposed to read, and it is supposed to analyze the gcode file while it is heating, and I set it to estimate time based on the above and not simply based on gcode file progress and it still isn't ever in the ballpark.
