Got in my order for On30 tieplates from Shapeways yesterday. The string of yellow plates are how they come .. still with the wax on them. Soaking a few minutes in some mineral spirits removed all of that as the white ones show ..  A close-up shows that the quality varies. I don't see any pattern though. The one in the center is ridged while the one directly above it isn't. Shrug. No biggie .. I have plenty that printed fine for the On30 bridge I'm making. Still curious though why the varying quality of the prints as you can see from the first pic they are all oriented the same.  |

Ok. I think I can answer my own question. FUD has a minimum detail of 0.1mm and a minimum wall thickness of 0.3mm Just checked. The tie plates are 0.290mm thick in the center and only 0.167mm on the edges. I'm simply pushing the resolution of the machine so sometimes I got lucky and sometimes not. *duh *  |

For those of you interested in 3d Printing you might find this radio prog interesting ......... worth following up on the links at the bottom as well http://www.bbc.co.uk/programmes/b012r7ty |

I don't know where modeling is going but this sure isn't scratch built, but it is 3D. 3D starts at minute 4:00 http://video.pbs.org/video/2153830403I wasn't aware that 3D had gotten to this point of adding interior and exterior colors and details. Although probably at quite a cost. I guess you could even design in the run down clapboards, split wood, knotholes, peeling paint and rusty hinges.  |

Yup...this is gonna cause some head scratchin' when it comes to the next "scratchbuilt", pre-coloured, pre-weathered, and fully assembled piece in future model comps!
Technology is just silly isn't it!
Thanks for the link.

I think you can relax for at least some years... If you have seen those models made on the Stratasys printers in real life, you would have seen that they in no way can compete with the stuff people on this forum can achive with conventional techniques. The finish on those 3D parts is almost like those of sugarcubes, no joking! Regards, Hauk |

I think you'll need to adjust your timeframe to months. There's a lot of variation in materials, with new and better materials coming out all the time. The early plastics did have that gritty texture to them, but newer materials have much less noticeable grain. dave |

I had this printed at Shapeways in their FUD (Frosted Ultra Detail) .. next to a penny for reference. The limit isn't the capability of 3D printing but the limits of my wallet .. this being the best right now relative to expense.  |

I received a phone call from Dave Rhoton at Ozark Miniatures yesterday. He recently purchased a couple of heavily vandalized high resolution 3D printers and has almost rebuilt one. He says their resolution is something like 0.0004-inch, good enough for jewelry without sanding or sandblasting. The units seem to be a step up from Print-A-Part's output and can produce masters from a variety of materials.
It's probably premature to mention this development because neither of the machines is in service. But if we allow some time, Ozark may be capable of providing very good quality.
I'll update this post when Dave tells me the first machine is in service and sends a sample.

This sounds interesting. We need something better than Shapeways, and a company that produces stuff for modellers might be more understanding to our needs. I think Dave will have no problem finding customers when he gets up and running. Regards, Hauk |

Russ, Did you ever get to try this program? Any results to post? |

No, Dave. I don't even recall downloading it because I still need to teach myself to use 3D CAD. I was hoping somebody else was familiar with it. -- Russ
