This is a great subject, it comes at a time when I'm starting to think about 3-D Printing, my only concern right now, is I have no clue where to start, I've been looking at some videos on who has the best unit or their top-5 units but I haven't found one yet that says this is basically what you need to get started. Obviously, I have a computer, an I-Mac but what type (s) of software do you need to get started? I've seen a number of different printers and I don't know what to start out with. I'm interested in making parts for some of my locomotives that seem to be lacking parts or maybe changing some parts out that are on there but could make the engine look a lot better if it had some more detail parts. Is there somewhere one could go to find out this information before investing a bunch of money and then finding out that it just may not be for you. Had that happen a couple of times and would really like to avoid it a 3rd time. It really seems like it would be very interesting and a lot of fun to do.
Great thread, thanks for starting it.
