3D Printing. What is it and how does it work? What is 3d printing? By definition, it's simply creating 3d models from generic rolls or bottles of material. Athough its so much more. There are extremely different technologies, materials and ways to 3d print. Basically process of 3d printing is based on providing digital 3d model and recreating it in real world, bit by bit. I'll try to answer all basic questions in this article. What are main 3d printing technologies? First and most popular one is FDM: Fused Deposition Molding. It's the cheapest and simpliest one (so it helps with it's popularity). Basically, as soon as you provide 3d model (digital one), it get's sliced into horizontal layers (as printer prints layer by layer), and then printer is melting plastic from a spool and placing it on heatbed (the base for your 3d printed model), layer by layer. There are of course lots and lots of materials to work with: ones with higher heat resistance (ABS),...
