JEM… and, all considering the purchase of a 3D printer,
Before buying a 3D printer I would suggest signing up with TinkerCad… it is a free, browser-based CAD program with interactive tutorials. Take your time and go through all the tutorials… then, take the simplest design that you want to create and create it in TinkerCad. At this point you have spent $0.00
Once completed, you will be in a much better position to decide which 3D printer to purchase... and, you will have a much easier learning curve to the software that comes with your printer and other available CAD offerings.
