First off, I'd like to thank Rio Benson for making the absolutely amazing drawings of the 1911 which can be found here.

DISCLAIMER: I will not be held responsible for any damage done with this model.



When I started this project, it was really just one of those things to see if it could be done. I did not use Rio's personal models; Instead I used his drawings and made my own. Internally, the gun doesn't function. The trigger doesn't even move. Externally, the model is completely accurate with the exception of the slide stop. The only moving parts are the safety lock, hammer, slide and barrel. I also had to change a few dimensions due to the 3D printer tolerance so if CNC'd; it may not work together as well. If you plan to 3D print it, then you will most likely have to use your own. I know that some companies that function like Shapeways are cracking down on the dangers of printing functioning firearms and may not allow you to print this file. If you do have the ability to print this, I Highly recommend using bright colors for the barrel or even the entire gun. While no laws in the US prohibit having this model on your persons, there are multiple instances of people (especially children) being shot by police for waving around fake realistic weapons. For those of you who think they cannot handle the responsibility or plan on giving this to someone who cannot handle it or just have no need for a complicated replica, I have supplied a slide without a moving barrel.

For reference, this was printed on a Dimension BST 1200es. I edited the dimensions specific for this type of modeling. No sanding is required on any of the pieces. I will be unable to complete the model the way I would like so the files I have completed are now available.

Other than the fact there is no barrel altogether for this piece, it is exactly the same.

What do the dimensions of the 3d printing surface have to be? My printer is only 200mm square, Is that big enough?

Vininski1 month ago

Hey fantastic model, this is just what I've been looking for since plastic toy replicas and even the full metal replicas are far to fragile (and expensive!) for filmmaking purposes. Hard to believe it's literally cheaper for me to buy a 3D printer and print them.


Just wondering which way you orientated the main frame on the build plate? I'm new to 3D printing and am not aware yet of a way to add support structure other than at the base without altering the model in other 3D modeling software.

Printed a few parts already that have turned out great. Thanks!

... its cool but its a bad idea, its not traceable,cant be detected by metal detectors, plus its easy to dispose of after killing some one... so yeah don't do anything stupid with this

you know if someone made this thing shoot actual bullets

No they haven't. If they did, it would require modifying the CAD files extensively, and adding a metal firing pin, and probably metal metal supports to hold the frame together.

And a Fused Deposition Manurfacturing filimint that is 100s of times better then any thing on the market. or a DMLS printer

I debated responding to this since this isn't really the place, but I can't allow ignorance of basic firearm principles and forensics to continue to be spread.

No firearm is 'traceable' in the way you mean. Serial numbers don't solve crimes, and forensics must link the bullet's markings with the rifling of the barrel to prove any particular weapon fired a specific bullet. There is no national gun registry, and dear God, may it always be so. Canada abandoned it's gun registry program after realizing it had helped them solve exactly 0 crimes. They don't work, period, end of story. They only serve to disarm the citizenry.

No working firearm has ever been created that can't be detected by a metal detector. Don't believe medial falsehoods on this point. Even the 3D printed Liberator gun can be detected by metal detectors. It has metal parts, and ... surprise ... bullets are metal. Advanced polymer technology may at some point change this fact, but right now it is literally impossible.

Your third point is moot, since it is, in fact, impossible unless you bludgeon someone to death with it. Also, all firearms can be melted down into pools of liquid metal at home. People just don't do it, and no it isn't hard or expensive.

The only thing stupid you can do with this print is try to pass it off as real. A threat that exists with literally every toy, pellet, bb, or airsoft gun on the planet.

WOOOOOW your totally totally wrong about the Canadian long gun registry.

We abolished it when we realized it was causing 100's of Crimes because it was designed and maintained by the same incompetent morons who obama hired to develop the obamacare website.

Also

the Unidentifyed Firearms act.... Does not specify metal detection. It specifys that a firearm Must be detectable by the most state of the art equptment.

It was never intended as a ban non Non metal firearms as The alquida aligned arms dealing california state senator leanand yee tried to imply. It also Origionally blatantly Encouraged legality of metal free firearms should newer and more effective Measures of detecting firearms and other weapons.

also The liberator even With out metal parts is 100% detectable by X ray and backscatter scanners.

so legally according to the Spirit and letter of the original UFA the liberator is detectable.

Thanks for dispelling the Myths that surround 3d printed guns. It's frustrating watching the media go into a frenzy and making false claims etc, all because it sells stories. Seriously, after seeing the claims that they make, it makes you wonder if they know how things like shoelaces work.

... It's a model?

although...... if you were to make this a nerf gun or something... or like a spas-12 shot gun... welllll

Awesome!
supah4x0r8 months ago

I love this model, maybe slowly deconstructing the whole gun for parts and create a complete replica of the M1911.

Im in Australia so there are a few different laws about undetectable firearms.

We are much more strict though in terms of prohibited weapons and gun control.

chubmcy1710 months ago

how did you print the frame? did you use a power printer to make this or just a regular pla filament extraction printer like the prusa i3 and makerbot? and did you print the frame vertically or horizontaly, and how do i get the correct scale on the pieces? Im planning on making this functional.

Looks like it has to be converted from inches to mm. Scale it up 25.4 and try that.

I'm going to print the handle scales today using the same formula, but the size looks right in Repetier.

Might be worth noting, the bullet has already been scaled by 25.4.

My printer:

Printrbot Plus

Repetier Mac OSX

Hey mate, I have a printer but the application (UP!)on the pc i use says its to big unless i make it smaller but if there is an easier way please tell me!

Samuel kos1 year ago
Mango I don't have a printer yet but plan on getting one by November, so I would find it very nice to have the files by then so I could mess around with my printer a bit

@gmyers2112 comment, the one below this one. The site is not allowing me to use the reply button right now so I had to do this instead.

First of all consider that laws are different in different countries. Not everyone lives in the US and it is unwise to presume this is the case when talking about gun laws.

Furthermore what you say is not entirely true under US law, which is the country I presume you are referring to when you claim it is legal. Specifically the undetectable firearms act does indeed make fully 3d printed guns illegal (for arguably good reasons, as they avoid metal detectors). Distributing the files for 3d printing guns is therefore a really bad idea because of all the aiding, counseling, ect. charges that you can be hit with. I am not a lawyer and therefore not going to speculate on how this law interacts with fake firearms, but I would advice everyone be cautious on the issue as a matter of principle.
Didn't he say that it was non-functional?
Not many people are shot with dummy guns :P
mangomango (author)  choward71 year ago
No but some people are shot Because of dummy guns. Specifically children who wave them around acting like theyre real..
what kind of child would have the access to a 3d printer and be stupid enough to go into public with it.. Just saying. Other wise nice instructables

hi, im more interested in what 3D printer you used to print the parts, seems really decent. thx
mangomango (author)  ccavute1 year ago
Dimension 1200es

Goodness sakes - it is just a plastic toy that doesnt shoot a damn thing. I have been keeping this instructable in my email so I could print this, and here I am with the printer and no drawing. Oh well - nanny state wins again.
mangomango (author)  Jensers1 year ago
Have faith Sir Jensers. I plan on restarting the project on monday just so i can finsih it and get all this off my back. Seeing as i only have a few weeks of school left, I will be hurrying. You won't have to wait much longer, but as a heads up i will make a seperate instructable.
Mr D.1 year ago
Looks pretty awesome, good work! You wouldn't happen to know what the 'Minimum Layer Thickness' of the 3D printer that you used to print this at your school is do you? Or the model of the printer so I can look it up?
mangomango (author)  Mr D.1 year ago
I used the Dimension 1200es which prints in 0.254 mm (0.010 in.)

What does it look like from the front (normal slide)? I just was wondering. Also, Shonenrek is my brother, and I am also interested in film-making. This might mean realistic stuff like Colt 1911's. Getting the models directly from some one like you who already has them would save us a lot of trouble in making them ourselves. also, does this model require springs? Sorry but I'm too lazy to read through it properly and some of it looks like springs........... ONE MORE THING! If you do decide to release the models for others, could you include the magazine with it? Thanks!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!111111111111111one
mangomango (author)  eadrian1 year ago
There are no springs at all. Even in the magazine. I wanted to do this 100% 3D printed. If and when I release the files, it will be the complete model. Many improvements have been implemented from what i have described on here. I will most likely make an entirely new instructable because so much has changed. If i get to a point where I can comfortably work on it, it will probably take me another 5-10 hours before I am satisfied with the project. It's so close to being finished that i don't want to release faulty files. I believe the files should be public within 6 months if at all. I know that's a long time but that's a worst case scenario. In the meantime, subscribe and check back for updates.

Based upon your photo I assume you are a Linux guy. That said, you are the type of engineer (someday) who when told it cannot be done you will do it anyway. While making a weapon in High School class is not the best idea you may have had. It was for educational purposes. I am sure the "man" in coming down hard on you and you're thinking any college scholarships and school choices may be threatened (from the tone of your latest edit). The engineers of the world are interested in the process the end product once it works no longer has any appeal.
Congratulations and I hope it works itself out and that no one panics.

I think you should be allowed to finish it (outside of school); I would think an internship at a manufacturer may be coming your way.


mangomango (author)  old_alex1 year ago
Nope, windows. but i don't see how that affects it. I used Autodesk Inventor to create the models. I am currently looking for a place to allow me to finish the build though, so keep checking back
3d printers don't really cost that much, you can find them online for only a few hundred dollars, and the whole family can use it! So maybe you don't have to find a place to finish. But either way, I do hope you complete it!!!
just build your own 3d printer. Check out The Ben Heck show. He's built several on there.
mangomango (author)  WhiteTigerTails1 year ago
The printer at my school is on f the higher end ones. I don't think the parts would work very well together if they didnt have the same level of detail.
relax it's not illeagal in america,so don't let the pc gun grabbing freaks scare you,
if they continue to infringe on your constitutionly protected rights sue thier butts off.
you don't have rights if you don't excercise them, if you don't stand up for yourself
no one else will.
Shonenrek1 year ago
This is really cool. Right now, I don't know where I can get free access to the stuff needed to make this, but I am interested in film-making, so would it be possible to get the models used for this?
wolfgang641 year ago
I commend you on two thing's especailly, first your forthrightness about your project and your sensititivity the the current situation. I have worked with guns all my life and also live very close to the Sandy hook area of Ct. so most people I talk to are rabid on the subject of guns one way or the other.
I give you high mark's for technical skill,honesty and comunication skills. I think you have a bright future in engineering.
One last thought, your product might have a reel place in personal weapons training. I can't tell you how many newbies I have seen do really stupid things with the loaded thing in the beginning military and civilian.
mangomango (author)  wolfgang641 year ago
Thank you, that truly means a lot.
gmyers21121 year ago
It is currently legal to make your own gun (a weapon for your own use and not for sale). In fact, it is more legal to make a real gun than it is to make a fake gun inasmuch as there are specific rules about obviousness for fake guns that do not apply to real guns. There is no current legislation concerning 3d printed guns and there are none planned in the near term. That would also mean that there are no rules in place for the distribution of the files required for printing 3d guns which by the way can be converted to digital machining tools to make most of the metal parts of a real gun (barrels are still pretty special parts). No serial numbers are required for your own home manufactured weapon and no liability exists for free distribution of files. Have fun everybody. woohoo
