Introduction
FDM a type of Rapid Prototyping.
A technique that fabricates a model of a part or
assembly using 3D CAD data.
Used for prototyping and rapid manufacturing.
Materials used:
Thermoplastics: acrylonitrile butadiene styrene (ABS)
polymer, polycarbonates, polyphenylsulfones and
waxes.
Maximum part size: 36”x24”x36”
Layers as thin as 0.04mm

Introduction 

FDM a type of Rapid Prototyping.^ 

A technique that fabricates a model of a part orassembly using 3D CAD data.

Used for prototyping and rapid manufacturing.

Materials used:^ 

Thermoplastics: acrylonitrile butadiene styrene (ABS)polymer, polycarbonates, polyphenylsulfones andwaxes.

Maximum part size: 36”x24”x36”

Layers as thin as 0.04mm

FDM method 

STL format file of the model is generated using CADsoftware(e.g. Pro Engineer, Auto desk inventor, Solidworks etc.)

The STL file is fed into the FDM machine.

FDM machine software orients and slices the modelinto thin cross sections. If required support structuresare automatically generated.

Advantages and Disadvantages ofFDM 

Advantages^ 

Intricate parts

Quick and cheap generation of models

FDM parts - strong and rigid- suitable for functional testing

No effect of environmental exposure

Thin wall or shell parts are made fast

Non toxic as opposed to SLA

Disadvantages^ 

Solid parts are made slow

Ribbed appearance – further finishing required

Part strength is weak in the direction perpendicular to build axis

Applications 

Conceptual models

Engineering models

Functional testing prototypes

Rapid tooling

Jigs and fixtures

High-heat applications (m.p. about 280°F)

Low volume production
