Railgun 3D print project (WIP, pictures!)

[Lazarus215]

So a couple of weeks back I had started working on printing a Railgun (ARC-920) and some of you may have seen my thread describing the issues In was running into with the model I had. Crimmson was outstanding in providing an alternate model, and I used that. However, I had wanted to add some things to the model (a functioning trigger, the payload well being able to open up, and making a power cell and projectile.)

So I went to work using some google-foo and figuring out how to cut up some meshes. about 2 weeks later, I finish with this! Obviously still a work in progress, but let me know what you guys think


Whole thing (About 37" long in total. It's under scaled by about 18% from game-specs, but this thing is massive to begin with.)

Cover and payload off the body
Disposable power cell and M645 Ferric Tungsten Projectile-High Explosive projectile

this looks awsome man hope mine turns out this good when i start to print it.

I'm assuming this is abs plastic, correct me if I'm wrong... But is it strong enough in that thin section by the top half of the "barrel" to resist wiggling? I've never worked with 3d printing before.

Regardless, this is pretty slick.

Thank you! Its actually PLA. the model does have a little bit of wiggling, but not under its own weight. you have to manually move the rails by hand for them to shift any. The thin white lines in the print are where I ran out of my silver filament and was waiting on the next roll to show up. As far as the structure, I cut the file up in a way that the top barrel connects to a massive chunk of the receiver. That piece of receiver connects then to the grip and the majority of the bottom barrel. I also added a 1/4" dowel in the bottom barrel that runs through 2 chunks of the receiver and makes it really stable. (adds some heft as well)

All the sections are held together with a generous amount of Loctite super glue, and reinforced with friction welded joints. (friction welding being that I put a piece of the filament in a dremel, spun it up to 15K RPM, and sealed up/connected the gaps.)

looking awesome =] any plans on a light track for the barrel? not sure if something like this would work

says it can be cut to length

I've got some EL wire from a different project, but its green. I'd love to throw some Blue on it, but the EL wire doesn't have a function where it will slowly light up going down the track. (at least that I know of) so it'd kind of be like the whole thing just starts Iighting up which is kind of lack luster. The other issue is then putting the power source and running wires, though the power source isn't an issue really since I have this massive hole in the model. I'll have to mess around with it some more, but I'll keep this post updated as I work.
