60 forum posts 3 photos | I am looking for someone that can 3D print a pattern locomotive wheel for me so that I can have some cast, it is for a 3.5 gauge Pennsylvania A3 Switcher that I am in the process of building. I have all the measurements for it and can supply photos from various angles of the pattern. All costs for material, postage and time spent in doing it will be covered so if anyone is able to help me out with this could you please get in touch. Joe |

220 forum posts 20 photos | It seems these castings are pretty expensive. For that price you can get a 3D printer and make the moulds yourselves. I have bought a 3D printer last year (artillery) and it worked out of the box (1 hour setup). Then I spend a few weeks of learning Freecad (every evening 1 Youtube video) to make 3D models. Now I wished I had done this years ago. Printing the moulds doesn't take much time. It is just a matter of inserting the USB stick with the file to print. The printer, can than run,unattended, for hours. Edited By Huub on 29/05/2022 22:38:29 |

1025 forum posts 204 photos | I am getting two parts cast for me, for making a milling machine flexure quill clamp and another of the same casting for the depth stop and DRO mount. The cost for these two patterns cast in Auckland in SG iron is close to $300 for them, that includes the GST and new courier fees. It is largely based on the weight of the casting and the man hours that goes into making the casting box up. I don't know anyone doing their own castings so was left with what it is. If I made the pattern so that one was required for each and cored the under sides etc and got the weight down, then the casting cost would have been cheaper. But they also have minimum order casting values as well, so in my case of only getting two or one of each, the price is around the same. I got my pattern 3d printed and cleaned it up a bit better on the sides so that it looked like a pattern should be with nice clean sides. Making things is a lot of fun, but computer 3d modelling of stuff is not for everyone, and I very well understand that as well. I know many that can make things on lathes, mills, edm etc, but just can't get their head around cad systems and cnc programing. The way things are, if the patterns in the link is what you need, my suggestion is to get the set and a lathe etc and start enjoying the process of making your project. If computers are your thing and you have the ability to learn new skills like cad software etc, then you can get a printer and print away and lots of things as well as patterns for projects or nick nacks for around the home, it's a hobby all on it's own these days. Most of all, ejoy what you are doing what ever it is you choose to do. I find that you can spend too much time trying to save money , and then end up not enjoying the process of the hobby. |

![]() 25215 forum posts 3105 photos 1 articles | As it sounds like Joe also needs the wheel modelled in 3D that is where the time (cost) will be not the actual printing. Could probably refine the surface himself to keep costs down or as they are not large wheels they would fit in a small resin printer and should then be ready to cast straight from the printer. Are the back faces flat or recessed? |

60 forum posts 3 photos | Jason in answer to your question the back faces are flat,I did see that castings were available from the US but the prices have shot up and it is now USD 62 per casting plus USD 100+ postage and them I'm sure I would be stung for some sort of tax or other at this end so I would be looking at over USD 400 plus tax.
