I wasn't sure if this was the appropria te forum or the user gallery.  Here is my first 3d printed gears from gearotic.  I did use a cad program to add a shaft so that the gear train fits without spacers, but they came out very good.  The large gear took about 20 minutes to print and the small one took about 6.

Awesome.. Smiley

 I love seeing such photo's. Still working on our 3d printer.. looking forward to being able to post
similar photo's in future.

Sonny;
 Nice job with these, why did you get a hollow rim and hollow spokes ?

Sonny:

Cool!

I'm expecting a Printrbot in the next couple months, and there's a couple other active 3D printer users here.  Any pointers you can share?

Keep posting those pictures, too!

@Art: I plan to print the full geartrain that I lasered before and have the two side by side.  I've added the shafts so that I won't need spacers.  A feature like that would sure be nice when it comes to 3d printing.  I look forward to seeing what you print!

@Bob:  That's a good question.  It should not have, but for some reason the slicer did not like the STL.  I'll have to run it through netfabb and try that one again.

@Kirk:   It really was pretty simple to take the dxf, extrude it to a bit, and create the STL.  I've spent a lot of time tuning my printer, so clearly that helps.  Beyond that, these aren't particula rly complex objects.  For reference though, you can see my printer creating a squirrel here: http://www.youtube.com/watch?v=8GU6SxTzSr4.  You can see a picture of the finished squirrel here: http://www.mounicou.com/prusa/prusa2squirrel.jpg.  Lastly, you can see my printer here: http://www.mounicou.com/venom/prusa2ps1.jpg.  Art, you can note that the acme rods, acme nuts, alum couplers, and alum idlers were all created on my mill or lathe using mach3 Smiley

   I just switched to slic3r  It is a blazing fast slicer, creates great G code if your extruder is a stepper driven type and it is much easier to set up. Some guys supposedl y are getting down to .01mm thickness per pass.

Dan,

I use both Sfact and slic3r now.  Slic3r is coming along quickly, but it still has many issues.  For instance, single wall profiles weren't supported until recently.  It is my default choice now, but I use sfact as a fallback.  Netfabb is an option that is used with the ultimaker s that I may consider at one point.  Its supposed to be the best/fastest if you don't mind the cost, but it is tough to configure .
