"Rails" would be extruded through them (TurboCAD calls it a "sweep") and all the slots would be "milled" with a series of 3D subtracts. This would make it simpler to modify the slot dimensions and test various rail holding methods. I'm not sure what economics analysis has been done for all plastic printed track? 726_261253_420000000.jpg FWIW, An example of 00/HO Slotted Rail base produced at a tiny fraction of the cost and time of 3D printing. I haven't had any reason to do a sleepers flush with ballast effect yet, but it's a pretty simple update.
