Hello everyone,I am trying to learn about the 3D printing world but don't know where to begin. Was hoping someone could adopt me and show me the ropes. Where should I start?What is a beginner/affordable printer I should be looking at?What formats are used for the 3d printing files?What software is easy to learn?What size limitations are there when printing? small trinkets versus large objects?What is there to know about the actual printing materials? Are there printers that print several materials?What overhead/maintenance costs are associated with printing on a daily basis? Are the "ink" materials expensive?My current personal projects wouldn't be anymore complicated than creating simple stencils for my work. But am hoping to evolve into something bigger.
