Hello everyone, I've been a model railroader for about 35yrs now. Got into 3D printing about 11yrs ago (using Shapeways and I-Materialise to print my designs). Purchased my first home 3D printer about 5yrs ago. I've been wanting to get into resin to brass or nickel silver casting from 3D printed masters for a few years now, and recently, thanks to family circumstances I've been able to purchase all the equipment needed for vacuum investment casting. Looking forward to participating on this Forum. I have many questions that I hope more experienced Forum members can answer. JeffB Central CT USA
