For a long time we have not discussed the specific printer models 3d. Today catch up. This article is very interesting 3D printer, which is called BCN3D Sigma.
FDM stands for Fused Deposition Modeling. It is a type of 3D printing process that can be understood as drawing with a specific “hot-glue” gun. It is also rebranded with an open source community like Fused Filament Fabrication, abbreviated FFF. It works by extruding a material to first point through a nozzle for crossing the section of an object, and then vertically move up, and keep repeating the process for all respective new layers.
