In this instructable I will show you how to make a fully 3D printable GlaDOS from Portal (1 and 2), that is also a lamp and can be converted into a robotic arm (how much cooler does it get), With a superled in the eye (this much cooler).

Go watch it immediately:

This was first intended to be an instructable on how to make a fully 3d printable GlaDOS robotic arm lamp that can also move. Due to some shortage in time and other project that I need to continue on (my SLS printer) I will share everything I have thus far that works properly. When I finally figure out how to make this thing moving without all the electronics heating up to 100°C, you will be the first to know.

Because this was first intended to be a fully functioning robot arm, some of the instructions include wiring. If you do not plan to use this as a moving arm, I have also designed parts to replace the servo's and moving parts. With this, you can skip most of the wiring and only use it as a lamp.

To make this lamp you will need a printer that is comfortable printing with a lot of support material. The design isn't supportless and is quite hard to print. I used a UP! 3D printer, that is more than capable enough printing with support material. All of the parts are designed around the maximum build sizes of the UP!.

Also you will need some skills electronics and be comfortable using power from the mains. Also you will need a LOT of time. Printing alone will set you back at least 40 hours.

A special thanks to Almteq in the Netherlands for letting me borrow first one UP!, and letting me borrow 2(!) UP!s when one couldn't get the job done fast enough with just one. Without you guys, this project wouldn't have been possible.

Okay, here's the deal. You seem to want to see this thing moving, and I seem to want to win an UP! printer of my own. This is what we are going to do. You help me win an UP! in the contest, and I will do everything in my power to make this thing move as soon as possible. The deadline for the contest is too soon for me to do it before the contest, so make me win, and I will make this thing move.

After more than one month of work, i finally finish it ! verry awesome modeling Op :) i've done it with some lights modification and i've use PLA material, the bargraph change depending on the temperature.

I'm here if you have any question

Mastrhix2 months ago

I also have an UP!, what settings do you recommend to remove support material?

dragonator (author)  Mastrhix2 months ago

Depends on the material. For ABS, anything will work. For PLA, the only advise I can give is either use UP! software 1.15 or 2.11. Anything in between sucks with PLA and support. 2.11 seems to be better, but I have to do more prints to confirm.

Hello. Give me please: circuit board and Arduino sketch.

dragonator (author)  DalekC1 month ago

The project was posted without either because I never got a decent design myself. I used a breadboard circuit to make mine move. It is nothing more than this example with 4 motors:


you can picture this board ?? or circuit ??

dragonator (author)  DalekC1 month ago

That board was never used in the actual lamp again. It was the old electronics, but it was binned because it didn't work. The only reason you still see it here is because it has a LED driver on it, which I used to power the led in the eye.

There is nothing I can offer here, sorry.

Thank you very much :)

Thanks a lot, working much better now, plan on finishing the project.

The thingiverse page is down? Could you upload a zip file?


Is it in any way possible to build this whole thing without the electronics, servos and whatnot?
I would love to make something like this but I lack the skill to create such an intricate electronic system and if I tried (judging by your comments about various things overheating) I would probably burn my house down in the process of trying to do so.
So is it possible to print all the parts and put it together as a non-moving GlaDos model? I understand that this would remove half the amazingness of it but this is probably the only way I could create such a master piece. Also if it is possible, are there any parts that would not require printing?
Also I could probably manage the lights part at the top of it, but not any of the stuff that requires more than knowledge on the complete basics of electronics.

There is a non-moving GLaDOS. Download the files normally and select the "Stationary" GLaDOS.

DarcieM3 months ago

Just a suggestion for the electronics, don't use a 7805. Use a LM323, which is 5V @ 3A. That should work. Even better, use a switching replacement for a LM323, like this one from ebay. That way, you are not dissipating that extra >7W.

I wired up the led bulbs with the driver and when I tested it they are blinking.Any ideas?

Check the packaging for the LEDs and the documentation for the driver you are using.

Some LEDs are designed to blink when they have power (like Christmas lights), and similarly the driver you may be using could be configured to blink.

If neither of those is your problem, I would check the current and voltage requirements of your LED and the current capacity of your driver; it may be your driver is struggling and the blinking is tied to a capacitor charge/discharge as it tried to keep up.

dragonator (author)  Backflash7 months ago

While I do not mind comments like this in general, I would at least like it if someone would spent more than 2.5 seconds on a problem before commenting. The Thingiverse tells you the files have been RELOCATED, including the link. The comments below also contain the link:


I will admit that I should probably add the link to the instructables page too, but that is no reason for your comment.

Hope it helps

Sorry about that. I did not notice the link, I should have digged deeper. I don't blame you for moving the files over Stratasys VS Affinia, I would have done the same thing.

gota say u used a ton of support material on bits and pieces that could have been added as smaller objects rather then part of the whole.

for instant add it from top down with a small slide wall, gives roughly the same strenght without wasting material

The head should be modified by someone to mount a raspberry pi camera in it. I would love having GLaDOS guarding my room with face recognition :3

Oh my.. That would be amazing!

I can just imagine having a friend walk in and wonder what's up with the light, just to have it turn around and tell them to identify themselves.

Im making a note here, hughe succes.

No but really, looks awesome man, i'll definatly try have a go at making one when my 3d printer finally arrives, thanks for the idea, info, and files
it was a triumph

Is there any chance I could get a copy of the firmware you used? I'm working on making Wheatley and this would make my project 1000 times easier!

What makes you think to make this models, dragonator?
dragonator (author)  pauluskusuma2 years ago
That really is a hard question to answer.

Like more people, I found that projects are a self sustaining thing. Once you finish one, you have thought of three more. I like things to be more than just stationary models (even though I also do like figurines). When you think of something for 3D printing, also think, is this all that I can do with this, or are there more possibilities with this.

3D printing offers many great opportunities and possibilities. All you need to do is find them and use them to the fullest.

winterfresh2 years ago
Regarding using a large PC PSU, why don't you use one of these switching voltage regulators? At ~90% power efficiency, they should be able to cope with the servos' power draw without overheating. Also, since they are very small they should easily fit inside of the base.

https://www.pololu.com/catalog/product/2111 (5v, 7A switching regulator. ~$25)
https://www.pololu.com/catalog/product/2110 (5v, 3.5A switching regulator. ~$15)
dragonator (author)  winterfresh2 years ago
I've looked at it, and that would be a great solution. I will however not implement any more power supply solutions (or practically any solution or fix for that matter). I am slowly closing this project and let the internet make it better.
MJoubes2 years ago
I'm tempted to take this on and try to find some way to make it motion sensing. Then apply that so that it'll watch me when I move around my room. If one wanted to, you could even work to give it idle motions and a little personality, though I feel that would require a larger scale and higher ceilings.
McDaver MJoubes2 years ago
I was already working on one before I saw this project.
My project uses a EZ-B robot controller to run her servos and give her vision.
She will track faces, motion and look around the room.
Mine will talk using a MP3 player and sound files from Portal 1 and 2. I am using a 3d model of GLaDOS that was ripped from Portal 2.
She will look spot on.
MJoubes McDaver2 years ago
I'd like to see a tutorial on how to rip things from Video games and print them on a 3d printer, seeing as how I'm getting ready to purchase one.
dragonator (author)  MJoubes2 years ago
There sadly isn't a quick and easy way of doing this. My advice is use plenty of reference images. To draw this, I used 10 reference images and one 3ds max model of GlaDOS in a different state (the starting up in portal 2 one). The drawing part took me around 50 hours.

Even if you managed to rip a model from a game, it still would need a lot of work. Game models are modeled for rendering only, they are split into many little pieces and have a lot of intersections. For 3D printing, you need 1 solid model with no intersection in the meshes.
Dr. dB MJoubes2 years ago
Brilliant! Something like a Roboboa brain would do the trick....
McDaver2 years ago
Your GLaDOS looks amazing. Makes a super great lamp and I am sure it will be a cool robot when you get everything sorted.
My old analog servos are over 30 years old and have plenty of power to move things and move smoothly too. If the servo you have is too week for what you are moving then you will have issues. I have been working on my own GLaDOS, but I don't have a printer yet. I am using an EZ-B robot board for mine because it makes prototyping so much easier. It also works with a wireless video camera, so I can see what the robot sees on my computer screen. This makes things easier to program.

Taranach2 years ago
Did you ever consider using vacu-forming for some of the parts? I see a few locations where a shell could be used that would be a lot thinner and lighter and would not overtax your servos so much. Sometimes a good framework with light cladding can achieve both function and form.
dragonator (author)  Taranach2 years ago
The shell is the lightest of the part of those pieces. 3D printers naturally print hollow and these parts are printed at a very hollow setting to save material and weight. Vacu-forming would add an extra step to this all, something for which I really hadn't time. I can also see only a few parts that would benefit from being vacu-formed, and everything other than the moving arm (the bottom) would not help for the weight on the servo's.

Lastly, I do not own a proper vacu-former so even when it was a better option, I couldn't use it. Therefore, I didn't consider it, But if I would have had one, I think I still would not have used it for this project. There are too many drawback for only one advantage.

Have any thoughts on using the acetone vapor method to smooth the posts instead of all the sanding?
dragonator (author)  rtkwe2 years ago
I printed in PLA cause the parts are very big, to prevent warping. Acetone sadly doesn't work on PLA. If you could have used ABS, I would most certainly have used the acetone.

i can't imagine going through all that trouble and not even considering how much torque you would need.  you can't just assume a servo is going to work just because it fits.  especially if you're going to buy the cheapest servos you can find.  

what i don't get is how your power supply could overheat at all.  it must be faulty or something.  i have a tiny little basic stamp circuit board, with a single-chip power supply built in, running four standard size servos with absolutely no problem.  and you're using mostly micro servos.  did you connect them directly to the 12V supply or something?

also, you list the servos in the parts list, but you don't list how you were controlling them.  microcontroller?  R/C controller?

other than the no movement thing, the lamp still looks completely awesome without it.  

one last thought... maybe you could have mounted the 3w leds behind the white plastic instead of cutting a hole for them.  that way the plastic would mute the brightness a bit and sort of diffuse the light.
dragonator (author)  thinkdunson2 years ago
I can imagine it, simply because it happened. This project was slightly over one month, from start to finish. Design, printing, prepping, painting, assembling, wiring, designing electronics, mounting. Corners were cut to get this thing done in time. If I did consider everything, this would have taken me months more. Plus, even if you consider 'everything', in the end, you will still find mistakes that need fixing (even though they will not be as big as now).

For the assuming part. I designed this thing for the biggest servo's possible in every location. There simply isn't more space for them, it just doesn't fit. I didn't buy the cheapest servo's possible for this project, I used what I had in stock (which was the cheapest). Wiring servo's to 12V would instantly destroy them. Servo's use something between 4,8V and 7,2V to power them. The problem is the current when the motors are stalling. The micro servo's alone (the cheapest ones) will use over 1A, and that is not even considering the big ones. The power supply on the circuitboard is only capable of supplying for the rest of the electronics, since it only supplies 1A at 5V. (This is problem #1). I would need over 7A of 5V to be able to supply the servo's with power when all motors are stalling.

For the electronics left out of the parts list. My designed electronics are not functional and are a hazard. therefore, I didn't share it. It is arduino based.

Mounting the leds behind the plastic would absorb too much light, there are 5 coats of paint over the plastic.
my point was that i just didn't think it should have been as difficult as you were making it sound.
but i still appreciate you posting the ible. it looks great.
dragonator (author)  thinkdunson2 years ago
I was a bit more attacking in my reply than I should have, but my point was that I am not simply banging rocks together (ha). Everything is there for a reason, and some problems really aren't that easy. Other decisions really were a bit sketchy, but that is simply time and me.

No, the biggest parts are 131mm (5.18"). You really need a normal up. This is the base and the internals. Also pieces like the ring pieces and the back would probably not fit in that build envelope.

You could try to put fans in GlaDOS its could suck in air near the top next to the ceiling and blow air out through the aperture logo.
dragonator (author)  c3ralki1l3r2 years ago
If you have seen what I have seen, you would know that that would be impossible. After I was done fitting everything in the base (including electronics) I couldn't even get a 30mm fan to fit. Plus if a power supply chip gets that hot that quick, something is horribly wrong.

I was wondering if I could have your permission to upload the models to http://www.shapeways.com/.

I cannot afford a 3D printer but that website prints 3d models for you and ships them to your door.
dragonator (author)  tampa22 years ago
If I would do something like that I would do it myself. There is one problem though. These models are designed for FDM, not for (probably what you would use) SLS (the cheap and strong). I can modify these models for SLS (hollowing out parts), but that would take me a good part of the weekend. Bear in mind shapeways parts would cost you a small fortune, even if I hollowed them out. (the head right now, unhollowed is 80cm^3. don't expect it to drop below 20cm^3, and thats just the head, one of the smaller parts)

If I receive enough interest, I will modify the parts for shapeways myself and I will upload them.
