Material Extrusion
◦ This common AM process uses spooled polymers which are either extruded or
drawn through a heated nozzle which is mounted on a movable arm.
◦ This builds melted material layer by layer as the nozzle moves horizontally and
the bed moves vertically.
◦ The layers adhere through temperature control or chemical bonding agents.
◦ The Material Extrusion process uses polyers and plastics. Eg.;Polymers: ABS,
Nylon, PC, PC, AB
◦ Fuse deposition modelling (FDM) is a common material extrusion process and
is trademarked by the company Stratasys.
