  • Shapeways parts

    Things have been a bit quiet here lately, so I thought I'd start a new thread about some Shapeways HOn30 parts I ordered earlier this month. They arrived yesterday and today.

    I got two cabs, a tender, freight trucks, and a dome/stack set. One of the cabs, the tender, and the domes/stack are for converting the Bachmann Spectrum 2-8-0 to HOn30.

    I ordered the majority of parts with white, flexible, polished finishes. The trucks were ordered in black, flexible finish. You can still see some artifacting on the cab roofs. Some fine wet/dry sandpaper should take care of it.

    Photo posted shortly.

      I see a lot of lurking going on, but no comments or questions. I guess this was a waste of time uploading the photos.

        We're interested, Jeff. Just waiting to see what you do with the parts.

          I read somewhere that on Internet Forums you have something like ..

          90% lurk and NEVER post

          9% post occasionally

          1% post regularly

          Perhaps you have only seen a portion of that 90%

          Ok. Question. You designs look good. Did you go with WSF and BSF for the strength? I had one item printed in WSF and was fine with the strength but didn't care for the resolution and finish. I've often thought that WSF would be great if you wanted to custom make a frame as it should easily replicate Derlyn. FUD is acceptable as far as resolution is concerned but then you have the problem with it being somewhat brittle. I assume that you went with the material that provides strength while giving away the higher resolution that is available in a relatively weaker material. I registered yesterday with ZoomRP. I just had a chance to check their PolyJet HD Blue material re: prices .. which is about three times that of Shapeways' FUD.

          This is their reference chart

          http://www.zoomrp.com/products.aspx

          and their PolyJet page

          http://www.zoomrp.com/polyjet-printer.aspx

          I didn't see anything about the strength .. but then I believe that for much of the 3d printing .. they need to be masters and the final parts cast from molds made from those masters. That works for me .. for things like the body shells and the higher price of the PolyJet HD Blue would probably be worth that. For things like trucks .. what we need is something with the strength of WSF but with a finer detail.

          One of these days .. need to look into this more as just a quick glance at the ZoomRP Quick Ref chart doesn't leave me dancing ...

            Ed,

            These are not my designs. I found them on Shapeways under Myner Models. The white plastic is Strong Flexible Polished. The black plastic is Strong Flexible.

            I guess you and George are the 1%

              In ten years we will take a picture of a train, email it some place and have a scale model waiting for us when we get back from the place we see the train.

              I can not wait.

                Have you checked out his rolling stock? I thought about using the boxcar to hide a sound decoder for one of my engines. The body is one piece except for the roof. You cut it out of styrene and glue it on. A guy on eBay sells n and Ho scale " sound car" kits.

                  in ten years time, we'll look back on these early 3d printed models, as the forrunners of that

                    I ordered some trucks last year and they worked out very well. It remains to be seen how they will hold up long term. I haven't run them much but I wonder if the journals will hold up in long term running. I'll keep them lubed. Other than that, I like the 3D stuff. I'm tempted by several things on the Shapeways sight. Your pictures are good and they show the "grain" left in the material very well. Once I rusted up the trucks the rough finish made them look more weathered. When I painted the trucks with a brush the material sucked up the paint which leads me to be live it is fairly porous stuff. I wonder if priming the cabs and then lightly sanding them might give you a smoother finish?

                      Patrick,

                      I have looked at the freight cars, but have not purchased any. They do look interesting. There is another fellow who has 3D printed bodies for cane railway diesel, a Decauville steam loco, a Climax, and a Puffing Billy 2-6-2. I don't remember his name.

                      Who's the guy selling "sound car" kits?

                        Railhead,

                        What wheelsets are you using with the trucks? I have some Intermountain plastic wheelsets that I plan to use.

                          OK, Jeff, I read this and am interested. No questions for now.

                              If you're concerned about wheel bearing wear, a good approach is to design the trucks to take the Tichy nylon bearings http://www.tichytraingroup.com/index...uct.php&id=232. These slip into an appropriately sized hole in the trucks, and provide an alternative bearing surface. Bernie Kempinski, for example, used these in his coal jimmy kits.
