3D printing has opened up a whole new world for us model railroaders!
I mainly print in HO scale using a resin printer (Elegoo Mars) for high-detail parts like figures, signal boxes, and engine details. For larger structures or accessories, I switch to my FDM printer (Ender 3) with PLA. The mix really lets me balance quality and speed depending on the project.
I’ve started designing some of my own models in Fusion 360—mostly simple things like crates, barrels, and fuel tanks—but I’ve also downloaded some amazing files from Printables and Cults3D. It’s incredible what the community has shared for free!
One thing I’ve learned: don’t skimp on post-processing. A little sanding and priming can make even a rough print look factory-made.
3D printing has totally changed the game for customizing model railroads. Whether you’re making detail parts, buildings, rolling stock, or even trackside junk piles—there’s almost no limit to what you can create.
What scale are you printing in? HO, N, O, or something custom?
Got a favorite printer, filament, or resin setup?
Have you designed your own models, or do you use downloadable files from sites like Thingiverse or Printables?
