Ask Slashdot: For What Are You Using 3-D Printing?
An anonymous reader writes: I've been thinking about getting a 3-D printer for a while: the quality is rising, the software is better, STL files really do seem a sufficiently good standard ("sufficiently standard," that is — I'm not worried that printers are going to stop supporting it anytime soon), and prices have dropped quite a bit. Importantly to me, it also seems like less of a jumping-off-a-cliff decision, since I can get a completely assembled one from places as wild and crazy as ... the Home Depot (not that I plan to). However, even the stretchiest practical things I can think of to print can't truly actually justify the price, and that's OK — I hope not to require enough replacement knobs and chess pieces to necessarily *need* one, and playing around with it is the main likely upshot, which I'm OK with. But still, I'd like to hear what uses you have been putting your 3-D printer to, including printers that aren't yours but belong to a hackerspace, public library, eccentric neighbor, etc. What actually practical / useful tasks have you been using 3-D printing for, and with what printer technology? What playful purposes? It's OK if you just keep printing out those chess pieces and teapots, but I'm curious about less obvious reasons to have one around. (And I might just use the local Tech Shop's anyhow, but the question still applies.) If you've purchased a 3D printer, are you happy with the experience? If so, or if not, what kind did you get?
For what are you using 3D printing for?
At the moment, nothing. It has a use for some small, niche scenarios, but it doesn't do anything for most of us here, and I really wish we would stop seeing stories on it every other week.
Why isn't 2D printing ever talked about?
"Set a man a fire, he'll be warm for the rest of the night. Set a man afire, he'll be warm for the rest of his life."
They're quite useful if you know what you're doing. For example, you have some kind of toy, gadget, device and whatnot...that's missing the battery cover? Hard to find...even on eBay, so what do you do? Fire up your favourite 3D software and make one. Works like a charm.
If you're working in advertisement/merchandise production... you can make small prototype samples of what you want to have mass produced, this ensures that your oversea production don't get it wrong (and they always do, trust me!) Shipping a sample of what you want mass produced, is a dream come true, and fortunately for (me) most of my competitors have no clue that this can be done, so they still do it the old fashioned way (try to tell the production team with drawings and talk over the phone with a foreign team that hardly understands English).
Pictures say more than a 1000 words they say, well...a prototype object to hold in your hand says more than 1000 pictures.
3D printers are a godsend.
What this world is coming to - is for you and me to decide.
It's nice to quickly be able do design and print replacements for stuff I happen to break without having to visit a store and adhere to opening hours. A selection of stuff I've printed that have actually been useful: Oscilloscope foot, fire alarm ceiling mount, a new and better 3d printer + a bunch of improvements to it, spacer for the kitchen sink, sprint sled, microphone mounts, electronics boxes, speaker stands, a block to keep the kitchen drain pipe at a good angle and parts for an old and broken curtain system that are no longer manifactured or available anywhere.
My 2 main projects I was planning to do with my 3d printer was make my own variant of the inMoov robotics project and also using PLA prints as a "lost wax" mold in aluminium casting (they would eventually fold into the one project after initial prototyping). However, I have an Ultimaker 1 and it is very unreliable so I haven't got very far. I am thinking about ditching it for a Flashforge Creator Pro but I'm waiting for the USD/AUD exchange rate to be more favourable to me.
I'm a trained CNC machinist with a 3D printer and I think your attitude is stereo-typically ignorant. Same type of argument usually made by people who drive pickups with a perfect paint job and refuse to buy tools from harbor freight.
Most of the idle crap people want from life can be accomplished with ABS plastic filament. This is true at least for anyone who doesn't work with their hands.
The home inventor personality is usually obsessed with achieving marginal improvements in efficiency which are typically too niche to already have products in existence solving the problem. Sword-chucks and triangle shovels are just a special type of arrogance from people who like to blame their deficiencies on the lack of their poorly thought through silver bullet solution.
If you have to sweat and bleed to get your pipe-dream produced in Aluminum or Steel, people will normally change their "only a carbon-fiber spork will do" attitude when differentiating themselves as having an "eye-for-quality"(aka ham fisted over-engineered for the situation's merits) becomes too costly.
I call it 'dollar store value'; for something about the size of a VHS tape, chess piece (Dalek pieces!) or smaller (er, like 6" square sort of thing) its about break even or cheaper to print it out; if its at all large, its cheaper to just buy it at the dollar store or whatever. You want to make a little box to hold screws? Buy it at the dollar store. You want to make a custom designed thing for your pegboard, or a case for a model car, or whatever.. well, perfect. Of course, if its a self designed thing, the printer is invaluable; you can design somethign, print it out, refine it, print it again. Its amazing. --> I've made a tricopter (liek a quadcopter, but no extra rubbish motors :)
So if you are a creative type, who doesn't mind learning to CAD (open source stuff), its fantastic. If you don't have time to CAD, you're relying on existing models to print.. check out sitrs like Thingiverse to see whats out there.
If you want to mass produce stuff cheap, its currently the wrong game.
Good for makers, not so good for consumers.
They have had kits that do not require a 3d printer for that for a long time now. There are a few different companies offering it. Here are a couple that I know of.

And I there there is a clone a willy kit somewhere but cannot remember the URL for it. All of these options are much cheaper than a 3d printer and you can put vibrators in them as well as glow in the dark colors and even lights. Lots of fun- just don't make a bunch of them and hand them out in the secret Santa at work next year. Trust me, it's not as fun or funny as you might think.
Well, the things that I tend to do most often is make my own tools for fairly specific tasks. One of my greatest eureka moments was when I realised that I can 3D print my own tool to open a watch case. It took a few iterations (plastic after all is weak), but I finally hit on something that's reliable enough, and it won't scratch the watch case. This was all because I took it in some years ago for a battery change, and the person kind of made a mess of trying to open it, they bent a strap pin, put tears in the leather strap, and scratched the case back. Fortunately it was my cheap daily watch, but still, I got paranoid after that, and had no intention of going to that person again. Now, I save a few dollars by buying my own batteries, and they're good brand ones too, and use a plastic tool to open the watch. No chance of marking it.
The point isn't so much that 3D printing is awesome, but it's really great when you realise that with this tool (3D printer that is) I can do things which I previously would never do. I'd never consider making a tool before unless it could be made with sheet metal and a hammer and file, and in some ways, the tool I made is better than one I could buy.
A little CNC machine would be pretty slick for that .. a CNC and a 3d printer are nearly the same.. one is subtractive, one is additive.. buy thery're "just" x-y-z tables; make an x-y-z and hang a dremel off the carriage instead of an extruder, and you've got a CNC that can carve out PCBs.
But as always, the problem with PCBs is.. vias; you can do one sided boards easy, but two sided, with via's.. plating and drilling/lining-up is a drag :)
Some filament is conductive, so the theory is about 3d printing the traces, which may work; not practical or cost effective right now (when you can submit a 4" square pcb design to Elecrow and get 10 of them for $10 .. thats hard to beat.)
If I had a 3d printer I'd custom design an Arduino case. I want to make one that looks like a tricorder, complete with slots for LEDs etc.

I use mine for all sorts of things. Missing battery covers, custom enclosures (Working on making a custom instrument panel for my project car powered by some 328p's), missing knobs and dials.
I regularly make things for my dad's bosses (Yacht charter company. Lost knob or plastic doohicky and want to buy a replacement? Fuck you, give us $300 because BOATS!). Lots of lost/broken/etc. plastic bits that cost lots of money to replace, I make the parts they want for 25 to 50 percent of the cost to replace them with OEM parts.
Right now I'm printing out a display model of a mechanical torson limited slip differential. Why? Because LSDs are pretty neat.
I'm using a makerfarm I3v 8" model. Comes in a kit, frame is made of laser cut wood. Best customer support I've ever experienced, no problems with the printer that have not been user error. I just got auto bed leveling set up and it's extremely reliable.
I carry around a pipe caliper that I designed and 3D printed. A scissor-looking device that tells you the size of a pipe (up to 4") based on outside diameter. Useful on the job.
I designed and printed a custom flashlight holder for those cheap LED flashlights.
Custom replacement handle for a triangular file
Set of custom drawer knobs.
Custom hard drive mounting bracket.
Custom battery holder.
Custom shelf bracket.
~Three dozen clothespins.
3-axis tilt camera stand that mounts on top of a tripod. (replaces one that broke).
Custom 80:1 worm gear reduction for a machine I was working on, as well as a few spur gears and light-duty V-belt pulleys for same machine. Custom thrust bearing and ball bearing holders.
A full set of Meta-Chess pieces.
A custom tool for aligning V-belt pulleys using a 3V line laser module and magnetic base.
Currently in progress is a mostly 3D printed racing wheel controller for my PC, which uses the guts from a dual analog game controller. The controller is unusable because the silicone pads for the buttons cracked, but the electronics are still good and with 4x analog axes I can get steering and three pedals plus 16 digital buttons. My hangup is I can't get the "feel" of the buttons right...
If I ever get off my ass and finish building the electric furnace I've been working on, and manage to melt some aluminum with it, I fully intend to try lost-PLA casting some aluminum parts. That's be awesome...

If you don't know what 3D printers are useful for, check out thingiverse.com. If your mind is not blown, then consider taking up knitting.
I use shapeways stainless steel 3D printing to make parts for physics experiments. It's only useful when the parts are small and can have sloppy tolerances. But in these cases it saves a fortune. I recently had a dozen small parts made for $200 that would have cost $1000 made by conventional machining. You can make screw threads (1/4 - 20 and larger; 10-24 might work) by printing the thread and then chasing the printed thread with a die or tap before use.
I'm a musician. I'd love to test some designs for trombone mouthpieces on a 3D printer. Trombone mouthpieces have been round for a hundred years because that's easier to manufacture on a lathe. What if brass mouthpieces could be different shapes? oval, oblong, rounded triangle? A 3D printer would be great for that kind of experimentation. Likewise, I'm also interested in unusual capo and string mute designs for a guitar.
Most stuff people interact with don't get 105 degrees C though. If you needed to make an enclosure for something or fix a piece of existing ABS/PLA plastic that broke, that's what you use a 3D printer for. You can also make prototypes for objects that you then send to a commercial printer, laser cutting facility or CNC mill to get created in the appropriate material.

A 3D printer is great for people who know CAD. I love my little Afinia. Sure, I have printed out my fair share of toys and models. But where it comes in handy is when I need something very specific to solve a problem both at home and work.
For instance, I bought my grandma a weather station for her birthday. However, there was no place to mount some of the sensors. After about a half-hour of design work and about 45 minutes printing time, I had some quick plates that I could glue to the shed and screw to the fence posts to mount the temperature and wind sensors. Sure, I might have went to the hardware store and looked for a solution, but that would have taken much longer than the hour and 15 minutes it took me to design and print something.
Simply put, if you know CAD or are willing to learn, 3D printers are great. If you are only going to print what other people have made, don't bother. After the toys and other tat, you will lose interest and probably feel like you wasted your money.

So, you see your truck as more of a "lifestyle" purchase than a utilitarian one? I'm genuinely curious, because I see a lot of people with big shiny pickups with cargo beds that have never been exposed to the elements, much less scratched by having something placed in them. Their towing hitches are perfectly chromed and have obviously never seen anything like a trailer.
I see some of them commuting into downtown Chicago for their jobs in the financial district and wonder what went into their decisions to purchase such vehicles.
You are welcome on my lawn.
where we get parts from engineers, so they cost something, most our parts (ymmv) are cnc out of acrylic with a Tomach machine
occaisionally it is cheaper to make things from the 3D printer
however, most of our parts require some smooth surfaces, and the CNC works better for us

The biggest questions you have to answer are 1) what material do you want to use, and 2) what the max size of your part? Personally, I like ABS. It is flexible and more forgiving and assembles easily with acetone. My favorite lowend 3D printer is the Makerbot 2X, however you won't get an iron man costume out if it with the 6x9x12 build volume. However, with a few mods you can print, ABS, Ninjaflex, and even PLA.
The Ultimaker 2 is a great printer for PLA, nice resolution, however it uses 3mm filament which is not as common as at the 1.7mm that most of the other printers use.
My lease favorite low end 3D printer is the Makerbot Z18.
It's all good fun, go for it!
But 3D printers are more useful for making enclosures to said circuit boards, not for fabbing them.
OSH Park. Why even bother with the decades-old milling and/or toner transfer method? I get plated vias, soldermask and silkscreen.
Mostly random stuff.

lol. Quite to the contrary.
True - ABS has limited heat cycles, and lowish glass transition temperature, but it's not immediately liquid @ 105C.
I've been using velocity stacks made from ABS on a race car for almost a year now - no issues what-so-ever, even tho it's the cheapest kind of ABS and isn't chemical resistant. They work brilliantly.
Nylon parts i've been using as well, harder to print due to the prep tho, but from Nylon which has even lower glass transition temperature car manufacturers make intake manifolds these days - even for turbocharged. Glass transition of 85C.

I have made practical, durable, every day objects. :D Yes, i actually race it, and have used those parts for a year now and they are holding up just fine and the car is rather quick actually, thanks for asking.
From small things like keychains to maxing out the envelope of a usual 3d printer. Hell, i even have 3d printed parts under the hood of my race car
Pulsed Media Seedboxes
Anyone who deems any kind of material unsuitable, not useful, or junk without knowing the intended application is quite frankly extremely ignorant. Plastic has it's uses, just like various woods, or metals.
Also what plastic things are you making out of wood? Are you suggesting molding? You do realise that each manufacturer technique has it's benefits and drawback too right, or are you ignorant about that too?
The things that I print range pretty widely:
- 3D printed prosthetics for people. See http://www.enablingthefuture.o... . Yes, home printers can make prosthetics that hold up to real world use, and for a lot of people (particularly kids and uninsured) the difference between $50 and $5,000 is insurmountable. Of course you should work with a professional if you can, for obvious reasons, but they're getting into 3d printed prosthetics.
- Parts that you can't buy. For example, a clip in my dishwasher broke, and the manufacturer only wanted to sell the whole drawer assembly for $400. So I printed my own, which have lasted for years. (Nylon)
- And parts that you can buy, but it's more fun (or cheaper) to make your own. Like a replacement watch band for the Pebble.
- Scans. I have a portable scanner (structure.io) and I scan people at Maker Faires and F&SF Conventions. Fun to share and print.
- Art. I like designing things and printing them because they look cool. And there's tons of great art to download.
- Personalized/unique stuff. I've published tons of designs using Thingiverse Customizer, that let you personalize or randomly generate a unique pen, your wallet, minions, snowflakes, etc.
That being said, I don't think 3d printing is quite at the level to be ready for people with no technical or artistic interest, because there's little for those people to do with a 3d printer. They can download and print other people's designs, but I'd think they'd get bored of that after a while. Designing your own stuff is a lot more fun!

Who cares? I want my plastic to melt at 105C. I want it to melt at just above room temperature.
I can make molds. Anything I can think up to print I can turn into a mold for metal. With a furnace and some wax I can cast iron.
9L+ diesel engines are still cast. If your bed as large enough you could 3D print yourself a small 2 stroke engine, check for fitup and then build yourself an entire engine from scratch.
"Die Cast" used to be a marker of quality. With a 3D printer at home you can make anything the average machine shop could have made during the industrial revolution.
And because you can do it in 3D with cheap plastic first you can reduce costs. You think a bad 3D print job is expensive? Imagine screwing up a mold design for a 12L engine.
You're screwing up Fahrenheit and Celsius here. 105 Celsius is before the plastic becomes slightly malleable and that is a little over the boiling point of water. So if you regularly handle steam without serious burning, let me know. Actually melting the stuff as it happens in the printer happens at ~200-250C.
Sure, you wouldn't be using it for friction pieces or things that are exposed to extremities, but for most of the objects in our environment we interact with, it's perfectly fine.

I see some of them commuting into downtown Chicago for their jobs in the financial district and wonder what went into their decisions to purchase such vehicles.
Conspicuous consumption mostly, with a hint of posering. They see that ranchers and cowboys are seen as manly, and want to be seen as manly too. So they buy a truck, which is what cowboys and ranchers drive. And of course only the latest and most bad ass will do, so it gets the full treatment: Lift kit, over-sized tires, brushguard, fog lamps, the whole works. Of course they will never use even a quarter of the features they bought, but that doesn't matter cause it is all about appearances.

SOME guys went off road - but their trucks looked like they had rolled over (and they had).
Ironically, most of the off-road enthusiasts I know preferred older vehicles because of that reason. A new vehicle getting rolled is a tragedy, while some old truck/jeep rolling is no big deal. And roll overs are a way of life in off-roading (hence why they have roll bars). So it doesn't make much sense to buy a brand new shiny jeep if it might get rolled on it's first outing, it is a better idea to buy an old beat up jeep and build from there.

(if you want to see what an old LR can do that a Sport can't, check out what Richard Hammond did with an old one - used its winch to stop it sliding and used the engine power and tyre grip to haul up the VERTICAL face of a dam! The winch can't do that on its own, anyone who uses a vehicle winch'll tell you that something rated for half a ton can't lift one and three quarter tons, winching a vehicle still very much depends on the drive axle finding a grip. The Sport went up unmanned and basically... well, failed to even get up over the kerb at the bottom).

Have you ever had a LEGO brick turn squishy on you? Because that's what they're made of, ABS plastic.
It's a plenty tough enough material that I used it to manufacture parts for a geodesic dome for outdoor use as a greenhouse, and it held up fine. I also manufactured gears for a friends high end RC car after the manufacturer had gone out of business. Those gears see a lot of stress, and they held up fine.
ABS is a great material, and so is PLA.

Roomba accessories? WTF are you doing with your vacuum cleaner?
Roombas break in certain, specific ways. For example, the (outer case of the) gear box often develops cracks. I'd like to be able to print out a new cover, because that's the only thing broken right now. Getting it replaced involves buying a complete swiper assembly, $100-150 or so.
Great thing about the Roomba is that these problems are well-known. I've been keeping mine running 7-8 years, replacing infrared LEDs, ball bearings and probably the outer gear box this year.

and they are researching into making 3d printing CHEAPER than injection molding, and they are already getting pretty darn close!
That will never happen for any kind of quantity because of the time required to melt and freeze (or UV activate or whatever other technology) the printed part. It's easy to get an injection molder to produce 1000 parts/hour. This is the point: 3D printing is great if you need a small run of a unique shape, or if you can't adopt a commodity shape. Or if the shape you want is no longer being manufactured. That mostly means toys, art, and legacy repairs. If you're doing anything "real," meaning 1,000 or 100,000 pieces, you'll use a manufacturing process with higher start-up time and lower piece time.
I don't think his heart is where he ended up taking it.
Part of my job is to design objects that will be used in a high-magnetic field environment, namely MRI scanners. Metal is not an option for me. Prototyping with traditional methods (e.g., CNC machining) is extremely cost-prohibitive. So I use 3D-printing. Some I do in-house with an FDM machine, in ABS. A lot I outsource to a better printer that can use other materials, say polycarb, or other methods, like laser sintering. At the end of the day, I get functional prototypes that I can check for utility, than design molds for injection-molded parts based on feedback from those prototypes. 3D printing enables me to do this part of my job. Without it, there would be no prototyping, due to cost, and thus no objects in the magnetic field. Truly a gamechanger.
