3D Printing by FDM (Fused Deposition Modeling)
This video is recorded to show how the FDM 3D printer work.
3D printing or additive manufacturing (AM) is any of various processes for making a three-dimensional object of almost any shape from a 3D model or other electronic data source primarily through additive processes in which successive layers of material are laid down under computer control.
Fused deposition modeling
Fused deposition modeling (FDM) is an additive manufacturing technology commonly used for modeling, prototyping, and production applications. FDM works on an “additive” principle by laying down material in layers; a plastic filament or metal wire is unwound from a coil and supplies material to produce a part.
Highlights of Fused deposition modeling:
Standard engineering thermoplastics, such as ABS, can be used to produce structurally functional models.
Two build materials can be used, and latticework interiors are an option.
Filament of heated thermoplastic polymer is squeezed out like toothpaste from a tube.
Thermoplastic is cooled rapidly since the platform is maintained at a lower temperature.
Milling step not included and layer deposition is sometimes non-uniform so “plane” can become skewed.
Make rapid progress in past few years and be used widely.
