So this could be really cool, making your own custom shaped keycaps with a 3D printer.
Thoughts?
-
The texture will be rougher. I believe they only print in ABS if that makes a difference to you. Also, if you do decide to make them, don't forget to make things roundish. Sharp keys may ruin your day.
-
Hmm, I wonder if maybe you could make them and sand them smooth, or rough, as needed?
I certainly don't have the spare income to drop 1k-2k on a whim, but I imagine there's someone out there who might, and considering that we see some crazy prices on custom keycaps (admittedly my opinion), the ability to make your own whole set might be a genuine idea to entertain.
-
I had a discussion about this in the "Make your own keycap" mod thread.
My uni's robotics soc has a 3D printer, but it's busted and they cbf to fix it. I was going to try and print some keycaps and see what would happen. But yeah, the result will most likely need some processing (sanding etc).
I'd like to own one tho, being a gundam modeller, It'd be nice to just print custom parts for projects.
-
I read somewhere that it wouldn't be accurate enough - not sure if that was fact or opinion though.

My worry would be the accuracy for the stem, It might not be perfect, but I believe it can be done (or fixed after it's printed). You can get the plastic out of the nozzle quite thin and the machinery should be quite accurate.
In any case some work needs to be done after printing to make it look right/fit.

Woah. Are those metal?
We could have Metal keycaps?
Time to go back to college methinks <<
-
I'm more excited about the prospect of CUSTOM metal keycaps.
I know metal keycaps exist, but imagine metal keycaps with crazy designs on them?

Shapeways will do it, though it'll be expensive.
imagine a metal vader keycap (OMG!)

It would figure a fellow named "Dork Vader" would be in love with the idea of a Metal Darth Vader keycap.
Know what would be really cool? Minecraft Keycaps.

You'd have to make them stackable.
I'm helping my roommate make circuits in redstone.

Ha! I get frustrated with Round4 BS, so go out on the web looking for this idea... and end up right back here at geekhack. :-P

Infinite loop!
My Uni's robotic's club seems to have fixed their makerbot. I will be bugging them to let me use it to make a couple keycaps to see what it would be like. = D

Good one DOX!
From click clack's info I get the feeling that he is using a makerbot to make his awesome art keycaps. Does anyone know?
-
Makerbot doesn't have the ability to make anything with a clean appearance like an injection molded piece. The printing tip extrudes the molten plastic at a constant rate, so the only real variables are the extruder tip (smaller hole) and the speed at which the printing head moves (stretching the extruded stream very thin). They actually have a page for all the known records for a number of categories regarding makerbot, one of which is the Highest Resolution: http://wiki.makerbot.com/hall-of-fame-highest-resolution
Just looking at the images there, the results are impressive, but you'd have to really sand it down to make it look like anything else on your board. Even then, they'd look pretty rough and obviously homebrewed. I still would love to get my hands on one of these things tho, haha.

This might be a better solution, its kind of like a mini cnc machine

Yeah that mini CNC machine is the way to go for keycaps i think :)

Makerbot > that.
You can print larger stuff. = D LARGER. BIGGER.Bigger Implies Better.
They are about the same price too.

Well personally Id still get the makerbot and put in the time to sand. I just like to have the option of making larger things if I wanted. Also the makerbot is a self replicating machine. You can print the parts to build a makerbot.

Did you mangage to try the Markerbot in your Uni's robotic's club?
I'm actually interested in that machine if we can make keycaps. Also, Do you know if it have the detail to copy miniatures?

I need to get round it. I'll try 2morrow since its a half day, so everyone has the afternoon off. The time for the machine tho is scarce from what I hear, since there are people who need it for projects.

Which makerbot is it?

Woops, Its a RepRap. == I swear they slapped on "Makerbot" on it tho.

anyone who lives in seattle, you have access to a makerbot and a laser cutter for 25$ a month. google studentrnd. i live 1/4 time in seattle; if someone can get me a printable file for a cherry keycap i can try this next time i'm there.
-
See, this is why I wish we had a local hackerspace here. I'd sign up for that immediately.
-
Okok, Robotics society finally fixed the damn RepRap. The president says he's gonna run a crash course on it within a week or two and I'll go to it and then make keycaps! They're using google SketchUp to design.

Make one already, I sent them a email regarding making keycaps but got no replies ;(
I still think the mini mill machine is better :P

I think you should have the posts connected at the bottom for stability. It seems pretty easy that one may break off!

I thought of that too, I'll be changing that... I thought it was pretty cool to do it that way. Then on the bus ride to icehockey I realized the problem of the pegs splitting apart.

Make the base of the peg connector a bit thicker than the rest, that way, it won't be as much of a stress raiser. You can only get away with it being flush to the top of the keycap like that if you have a round stem, The square one that meets flush will have significantly more stresses where it meets.
It's starting to look really good. How hard was it to define the front mesh (that the finger contacts) ?

The front mesh was not too hard. Tho SketchUp isn't very helpful with making round surfaces. There was a little trick to it, but not too much. The rounding of the edges was done by a ruby script I DLed.
I'm not sure what you mean with the pegs tho. Is the base of the peg connector the but round the keycap, or the bit that connects to the stem of the switch?
And about the round stem...I'm not sure if the stem gets so much force that I need to design it so carefully. Also given the way the plastic is laid out, I don't think there isn't much benefit between round and square(?). Also a round stem makes some bits particularly thin.
I dunno, I'm going to print this one out first and see how that goes. Also I don't think the reprap can print the curved surface. I'm thinking in my mind that no matter that orientation I print it, I can't make the curved surface...
If I print from the base to the top, the surface becomes this roof thing dangling in the air, that the RepRap can't print. If I start the other way round, the curved surface would face the table, and once again we can't print on air...
-
i really have no clue about all this stuff but maybe you can shape something with that curve and use it as base to print on?

I'm probably gonna make it flat, and then file off the surface till its curved.

that will make each cap unique, but at the same time it will be a lot of work i guess.
-

I can't see a way around it, because of how the reprap makes things.
I may have to conclude that 3D printing of keycaps is not the most efficient way of making keycaps.
-
wat? why can't it make the cylindrical bit?
-
well if you think about it, how should it do it?
it can't print in the air :P
-
the reprap isn't an extrusion printer?

I believe it is.

then my question stands
-
then my question stands
It can make curved surfaces. but due it putting on layers and layers, it means I have to start from the base of they keycap or the top. If i start from the bottom. I can't actually print the top of the keycap because it'll be printed on air. If i print from top to bottom, the curved bit would mean some of it is "printed on air". Again it doesn't work.
-
Can you make it solid?
-
my impression on extrusion was that you could eg print an arch with the curved surface facing down as long as the radius was small enough.
anyway if nothing else you can print a flat key just to see if the thing can print walls thin enough for caps.
-
My best friend's dad has one of those at work I have never thought about making keycaps though hmmm...

I dont think the top is angled right. But well see.

Here's one for Ripster, the LEGO lover: http://www.youtube.com/watch?v=pX1cO2XhMrg
hazeluff, why don't you create a base for your keycap out of clay that you form simply by pressing an existing keycap into? Then when you build on that you'll get the proper shape. Alternatively, build up extra thickness, and simply take a large drill bit to it, along the side, which will grind away the cylindrical top to the keycap. :-)

The clay idea doesnt quite work. Km lying in bed so i cant be bithered. But j am desjnging a flar top anf then sandin off the curved park. Im srill waiting on the guy to hold his crash coarse on how to use the machine.

No. Just woke up

ow. i guess i wouldn't type better in that case :D
but i don't go to geekhack from my phone usually.
you geek!

Yeah, its the first thing I do when I wake up. Its really hard to wake up in the morning and get out, so I use geekhack to start gaining consiousness.

was the printing of the flat keycap pulled off in the end?:P

I got really busy and couldn't even have time to ask them if I could use the machine. And now that I have time, went back to them, they seem to have destroyed the printing nozzle again. So don't count of me delivering anything... T-T
-
ahh, thats a pity! Wonder if my ex-school has one.....i doubt they'll even let me get near it though.

Here are examples of better resolution than what was posted earlier for the makerbot. This is an ultimaker, still an extrusion machine. I'm not sure what makes it better, if it's just better software techniques or the machine itself is more accurate.

In response to some previous posts.
Here are examples of an Ultimaker getting higher resolution than the makerbot record that was shown. I think some of this is due to better software and could be replicated on other machines.

You can "print on air" with a dual extruder where the second extruder prints dissolving support material.

Very interesting stuff. Thanks for the dual-extruders method of outputting a plastic and solvent, I hadn't thought of that. Keycaps way be entirely possible. I still want some decent home SLS machines to come out, so I can quickly rapid prototype ceramic keycaps, but pulsed lasers that high power are scary, and there's lots to worry about what with focusing, etc.

We have a Makerbot here at work I could use on the weekends. The problem is sourcing a 3d model. I don't know how to do it yet. I've looked up a few tutorials for Makerbot though, and since my co-workers have already set it up and calibrated it (Industrial Design team) I can just sneak in there with my acrylic and get to business. Again, I would need the CAD files, or to spend some time learning how to make 3d models. Thingiverse don't have no keycaps :(

I REALLY wanna do this.....
Edit:
Just talked it over with the ID lead and he gave me the OK to go ahead and print what ever I want. So I'm just working on getting the 3d models ATM
