Fused Deposition Modelling (FDM)

Company : STRATASYS Inc.

Process

Thermoplastic modeling material,(0.070dia)

is fed into the temperature controlled FDM

extrusion head and heated to a semi liquid state.

The head extrudes and deposits thematerial

in ultra thin layers on to a fixtureless base.

The material solidifies, laminating to thepreceding layer.

Model is built using a thin filament spl. Quality ABS,Wax, M-ABS

Ballistic Particle Manufacturing

PROCESS

Micro particles of molten thermoplastic arejetted from a piezoelectric nozzle to a definedlocation,freeze and then form the

model,particle by particle A single robotic head positions the nozzle with

five axis of motions,one of which is the Z-axisplatform

Models are built free standing with automaticsupport generation where needed,either inhollow shell or cross-hatched mode
