alternately, pragmatic modeling. I've been prototyping a lot of stuff lately, tools mostly, in stainless steel. It's been one hell of a learning experience. Would like to hear about your projects, process, outcomes, etc.
>>
>>519358
No way of cutting that shit ontop, m8, only if it's cast, but good luck casting a 1x3 cm stainless steel object. Also, the thread seems too bulky, it will have trouble penetrating hard surfaces like wood.

Not on purpose... but since it's just for my own personal use, IDGAF I guess.

>swastika screw
>Nazi driver
How much torque can you put on that Nazi-driver before it blows into pieces?
>>
>>519371
With 40 points of contact is has the highest torque to surface area ratio of any drive system yet developed. I sincerely doubt it will ever "blow".
>>
>>519362
not stainless steel

>>519363
even if it penetrates, that doesn't mean it's smooth, I penetrated your moms ass last night, but it was tight as hell

Also, the thread is turned wrong, it should be screwing in the way of the swastika, that way you can apply the best torque while screwing it. I don't know in what shithole of a country you live, but in normal countries people screw clockwise.

Btw, this swastika design is cool as fuck, but unpractical, unscrewing will be as bad as a normal screw at best. Also, I've talked with a friend about it, it is possible to produce them from ss, silly me, I forgot screws were made by deformation, not removing material. Anyway, the thread is fucked up, you need to make it thinner. It needs to be able to cut your finger.

Good god I don't know where to begin on programming this. Printing this would be easy, Ali would need is good support. But programming would be an absolute bitch.
>>
>>519402
You can print in stainless now. It's just a little more brittle now. Still, something like this would be good for penetration.
>>
>>519621
Way more expensive than just mold-forming wire/rods, especially for something like screws.

Here, I made this parametric screw in OpenSCAD to prove you wrong. It's kinda broken because I did it in like 30 minutes, but it works for most reasonable parameters. And in this orientation it shouldn't need any support.

I also haven't cut the drive/slot yet because I'm lazy, but if I still care enough to do it later, I'll come back and share the code.
>>
>>519929
I know, right? 3D printing is just building up steam, and yet... That feel when you hold something in your hand that you modeled, it is like being a true god. I would expect many more artists to be trying it out and talking about it!
>>
I also made a video going over a few things & showing the screw in action:

https://www.youtube.com/watch?v=9rh1Tb3-iiI

I also noticed economics was brought up, and that is clearly critical. This screw cost me $8 to print, obviously unreasonable if you were needing a lot of them. Which is why my next project is to print a mold with perhaps a dozen. I am planning on experimenting with non-metallic compounds. Ceramic, fiber reinforced screws, that was my ultimate goal after all.

What do you know, I'm actually a /diy/nosaur from /3dpg/ and I ran across this thread. What do you know.

First things first. You're really going through the process of printing your own screws and then burning them out? Why?

Have you visited /po/ yet? It takes more skill than modeling and prepping for 3Dprinting.
>>
>>521037

I got into construction recently & am very unsatisfied with the state of fastener technology. Since I was already doing a lot of 3D printing, I started thinking why not just make my own for kicks? It's a fun challenge, that is the short answer.

Is that a spacecraft from Eve?

>>521039

My first time visiting /po/ I have a friend who is obsessed with papercraft, DESU while I find it cool I also find it kinda dull with limited utility. Most folded stuff reminds me too much of low-poly. I'm more into the 'functional' rather than 'artistic' side of 3D.

It's an interesting idea. I might give it a shot to see what I can whip up. I am sick of fucking hex sockets that always strip.
>>
3D printing is really cool but the idea of filling my desk with (more) knickknacks doesn't appeal to me, and most practical things are cheaper to buy rather than print.

Basically it just seems really impractical to own or use, even though it's tremendously cool. All that said, if I were into table top gaming and had local friends that were into it, I'd be printing up a storm

Gonna have to make two posts for this. Im pretty shit at 3d modeling but I made this last night for 3d printing. problem is when its loaded into cura it likes to only load half the model.

Try to load it into Slic3r, I know it has options to fix a lot of STL problems

There are other utilities that will fix STL files to be watertight and all the other issues that would make your models be fucky in cura. Look up Meshlab

Tried both and it dosn't seem to be helping. I did try rotating the model in cura and it game me new floating bits so im not even sure if its a model issue or a cura issue.

does anyone knows if Matlab exports STL files? i need to 3D print a function and i can't find any software that can graph them other than matlab
>>
>>519368
Here, have a Swastika fence, get over it...
>>
>>521494
I have heard that Matlab can do more or less everything, so I assume that it can. If you don't find any other solution here is what I would do: I would create in Matlab Point Cloud (it is just x,y,z coordinates in txt file) and then import it to Solidworks. If you don't have solidworks try to find some free 3d scanning program, some of them are also using point clouds. It is not the best solution but it's something if you don't find anything better.

Either you're a masochist, a CS student, or just fucking insane. Or I misunderstood something.

I don't understand what you're trying to say. Blender opens STLs fine, if that what you need.

I think he is trying to make 3d printed object of some 3d function (equation).
I am mechanical engineering student. I have very basic knowledge of Matlab and a bit better knowledge of Solidworks. Solidworks can do equation driven curves, but I am not sure if it can do surfaces, so if I would get that kind of project to do in very short time I would do it like this: >>521553

If you are good at programming try Openscad

>>521494
export it in 2d image (as height map) and use the image in any 3d modeling sw as displacement on plane/cube

Just finished another model & ordered a print in Shapeways new PLA option. Will update when it arrives. This is a different type of 'quick connect' for garden hoses. I'm still playing around with hermaphroditic interfaces.
>>
>>521492

That's a model issue. If you go into expert mode, you can tick different correction rules for a model that might solve your problem.

Otherwise, you can go to the netfabb service provided by microsoft and upload it to be fixed. This usually doesn't take more than 5 minutes and only requires that you have a microsoft login (hotmail will do)

The model needs to be one continuous, manifold piece with no intersections.

Does anyone here have any experience with flexible 3D printing materials? How soft can you print nowadays? Or would it be better to 3D print molds and fill them with liquid silicone?
I'm sure you can guess where I'm going with this. Has anyone ever tried it?
>>
>>524680
Either mold it or make a hard print and seal it with silicon. Otherwise you can have residues setting between the layers that are hard to brush off and will probably cause infections and bad smelling later

The softness depends on the shell, infill and even on the type of extrusion your're using. It can vary from very soft to rubber ball hard
