Title: DIY 3D Printer
Post by: z.monkey on December 05, 2013, 11:54:19 AM
I'm thinking about using this to build my next alternator, DiaMag24, a 24 pole, 12 coil, single phase, ABS Plastic rotor/stator, magnetic liquid cooled alternator...

We shall move forward.  Let there be lights...

Hey, with those 3-D printers, even the best one, one can make only a NON-WORKABLE SCULPTURE, nothing else! The material used is always PLASTIC and nothing else. Can you make a working screwdriver? Unfortunately, you can't. You can make only a plastic sculpture. Only try to unscrew a screw with it. I have no idea, why people consider 3-D printers so "miraculous" machines.

Here is an idea for you Quert.

Print the  part, press it into a sand mold, then remove the plastic part, and pour in aluminum.

There is lots of stuff usable as plastic.  Here are some ideas...

Casting alone is not enough in most mechanisms. For example there is shown a gun; it won't work when made using only casting parts. Most mechanisms require parts which need thermal processing or plasticizing, for example. As I said before: 3-D printer is good for sculpting only. And still requires a lot of knowledge to be useful.

Not agreeing with you, you can do a lot of things much better than with manual tools, eg. a rotor that does not wobble, has snap-in pockets for your magnets, has a nice design, a mix of gothic and alien structure if you like... just copy paste in the modellung app, wysiwyg...
Probably looking better than a test device glued and taped together using some trash.
Watch the EZ spin motor vids of laserhacker on utube, they are printed. Running since two years from a crystal battery.


3D Printers are great for prototyping and a good companion for a CNC mill.


Both however is slow and loud. And a DIY 3D printer sounds like a lot of work that may result in imperfect prints, I'd rather buy one, they became rather cheap.

Nice 3d printer, but the cost must be high to build?

This is my under $200 complete 3d printer.

looking pretty good. 0.4mm sounds ok, esp for a diy.  But you must love the building and fiddling. I do not often buy things, so I hope my next phone has a 3D printer built in.
Can you show something you printed with it?

I watched a video on Hackaday where a guy built this huge concrete 3 d printer and built a house with it.  Layer by layer, the house was formed.  This technology is useful, in my opinion, and yes, it is still in the beginning stages.  Just think a little bit about where this can go.  There are also folks printing with molten metal...now you have something useful.  It will get better and better.
