FDM

Fused Deposition Modeling (FDM) is a material extrusion layer additive manufacturing technology which creates accurate and strong parts with industrial grade thermoplastics.  Fused Deposition Modeling machines 3D print parts layer by layer from the bottom up by heating and extruding thermoplastic filament.  Fused Deposition Modeling technology is ideal for conceptual models, functional prototypes, engineering models, fixtures and jigs, and low volume production parts. A part is designed using a 3D CAD system such as SolidWorks, AutoCAD Inventor, ProE, etc.  The native CAD file is exported to a STL file which is a rendered surface model used by 3D printing software.  The STL file is then processed through the printer software for orientation on the build plate, layer slicing, and placement of the support structure.  The file is sent to the printer and a dual extrusion head prints one layer at a time with one head printing the thermoplastic build material and the other head printing the support (scaffolding) material where needed for overhangs and undercuts.  When all of the layers are finished, the part is removed from the base plate and placed in a detergent bath to remove the support material.  When removed from the bath the part is rinsed and ready to use.  Soluble support material allows designers and engineers to create complex features such as undercuts and internal details. abs-plus-colorsFDM printers offer the advantage of fast, cost effective, and complex parts made with tried and tested industrial thermoplastics.  Another advantage of Fused Deposition Modeling printers is the wide variety of filament colors available for prints.
