3D Printing - General Thread

[Bill Gill]

Stumbled onto this site/store at Shapeways and thought some forum members might find these circa 1915 crawler models interesting. But I can't find what scale(s) they are https://www.shapeways.com/designer/tracmodel/creations

I read under the pictures two at 1:87 - HO and last one, 1:64-S. Look good.

They look pretty good. I randomly choose the 45 HP 1915 one and it is available in S and O scale.

They usually show renderings of the models. In this case, every image in the link is a rendering. If anybody actually buys one of those models or anything similar, please post an image of its appearance before you clean it up. Might be educational for many of us. -- Russ

A plea for help.

I have neither the aptitude nor the inclination to make digital drawings for manhole covers for my ongoing projects. Does anyone have a suggestion for a person who does this kind of work (and I am happy to pay, of course)?

Thanks for your help.

Many of us could help you. Ed Traxler seems to be our current resident expert but even I might be capable of something like that. I am very slow, though, because I don't use SketchUp regularly so use me as a last resort. -- Russ

I just pulled this up .. something I did a while back for my own amusement. Do you have anything specific in mind for the design, name etc." Scale etc.

Bill gill,   I believe the tractors  you spotted were being sold on E-bay from somebody?  I had them on my watch list at one time. They were selling O scale...S and HO

Thank you, Craig.

Ed! Good to see you posting. I like the manhole itself along with the cover.

Thanks Russ and Ed. I am getting some very generous help from a forum member. I know it has been said before, but this forum is incredible.

hey .. it's part of why we hang out here I think. Sharing is like a series of mini-lessons

Russ left a remark back in December about the results from 3D printing as compared with the "computer image" on adverts.   It is definitely a case of "buyer beware" (other than Shapeways who produce some good stuff). I have had a chimney and dome 3D printed for my 16mm scale Garratt - superb (not cheap but worth it), however there are now an increasing number of manufacturers offering 3D printed items. Having just purchased some items I find they are only fit for the bin.  Are they using cheap home quality printers and then selling these items commercially for a quick mark-up?    Has anyone else had such bad experiences.

Interesting. I'd love to hear more details on what you have been finding

I've been running a test over the last year or two comparing 3D print jobs of the same file. One was from Shapeways, two from different printers at local libraries, and one from my cheap $200 entry-level printer, a Monospace IIIP v.2. Attached is a photo (not the best quality photo I will admit) of the four pieces side by side. Just out of curiosity, which one came from Shapeways and which one came from my cheap entry-level printer?

At the Friends of the East Broad Top reunion this weekend a vendor had some 3d printed parts foe sale.  The printing base for one of them had a surface pattern which in a larger scale could represent a generic access cover.  If you need one with a particular logo on it that would be a bit harder.  But for a generic cover just print a circular base you would use to print the part and you would be done.
