Control Parameters and Materials Selection Criteria for Rapid Prototyping Systems
Since the introduction ofrapid prototyping technology as a tool for time
compression and concurrent engineering in the design and manufacturing process, many
enhancements and refinements have been made based on the experience ofusers and
manufacturers ofrapid prototyping equipment. These improvements contribute
significantly to faster production of quality output from rapid prototyping systems.
There are diverse control and material selection parameters that affect prototype
models built using the Fused Deposition Modeling (FDM®) process. This paper reviews
the role of several ofthese parameters in the process. Data will be presented to help the
user choose the appropriate material for specific applications including density, tensile
stiffhess, flexural stiffhess, tensile strength, flexural strength, tensile ductility, shock
resistance, and hardness.Mechanical Engineerin
