Fused Deposition Modeling (FDM) Technology Overview

Fused Deposition Modeling 3D Printing Technology

FDM 3D Printing Rapid PrototypingFused Deposition Modelling is one of the 3dpriniting technologies that was invented and developed by stratysys in the 1980s.

It’s a solid based rapid prototyping process that heat the material usually in the form of filaments or wires and extrudes it the form of very thin strings along the desired path.
Fused deposition modeling Process The part to be made is modelled and sliced into layers and exported to stl format in softwares to prepare it for the build process.

The 3dprinters working on FDM technology heats up the filament material and extrudes it through a nozzle along the extrusion path layer wise based on the data from the stl file.

Support structures are generated if needed. In the post processing support are removed either by breaking or dissolving in a suitable solvent.
  • ABS - Acrylonitrile butadiene styrene
  • PC - PolyCarbonate
  • PLA - Poly Lactic Acid
  • PMMA - Poly Methyl Methacrylate
  • Typically used for applications that need strength and decent accuracy. Used for functional prototyping and fitment analysis. Typical industries using FDM:
  • Manufacturing including automotive, dies and molds, aerospace etc
  • Art and Craft
  • Architecture
  • Health care
  • Concept models for retail and advertising
