What is Rapid Prototyping?
5510
A stereolithography material known as RenShapeŽ SL 5510 designed
specifically for the SLAŽ 350/3500/5000 systems. For more

Fadeometer
An apparatus for determining the resistance of resins and
other materials to fading. This apparatus accelerates the
fading by subjecting the article to high intensity ultraviolet
rays of approximately the same wavelength as those found in
sunlight.
FRP Fiber-glass-reinforced
plastic is a composite material consisting of glass fibers
in a polymer matrix. functional groups Groups of atoms that
impart a certain reactivity to molecules; functional groups
also make it possible to distinguish material classes with
corresponding chemical properties (e.g., hydroxyl groups of
the alcohols, carboxyl groups of the organic acids, amino
groups of the amines).
Filament
A continuous thread of a specified diameter, e.g. silk (natural
fiber) or rayon (synthetic fiber); the opposite of a fiber
with a finite length, such as wool or cotton.
Filler
A cheap, inert substance added to a plastic to make it less
costly. Fillers may also improve physical properties, particularly
hardness, stiffness, and impact strength. The particles are
usually small, in contrast to those of reinforcement; but
there is some overlap between the functions of the two types
of material.
Final Machining
A secondary operation in which parts formed by a rapid prototyping
method are brought to acceptable final finishes and tolerances
typically by subtractive CNC technology.
Finish (part finish)
A qualitative term for the appearance of a part. For example,
technologies based on powders have a sandy or diffuse finish;
some inkjet technologies produce a smooth finish due to use
of extremely thin layers; sheet-based methods might be considered
poorer in finish because stairstepping is more pronounced.
Flame Retardant Resin
A resin which is compounded with certain chemicals to reduce
or eliminate its tendency to burn. For polyethylene and similar
resins, chemicals such as antimony trioxide and chlorinated
paraffins are useful. flexural strength The strength of a
material in bending, expressed as the tensile stress of the
outermost fibers of a bent test sample at the instant of failure.
With plastics, this value is usually higher than the straight
tensile strength.
Flibbertigibbet
A silly, flighty person.
Flow
The qualitative description of the fluidity of a plastic during
molding.
Flow temperature (FT)
Temperature above which a thermoplastic can be reshaped with
little force. fluidized bed process Powdered or fine-grained
material (e.g., quartz sand) is swirled upward by rising gases
at a certain characteristic flow rate in such a way that the
system resembles a liquid with respect to many of its properties;
when used in the pyrolysis of plastics, this method allows
heat to be transferred rapidly and the process to be performed
in closed reactors.
Foaming Agents
Chemicals added to plastics and rubber that generate inert
gases on heating, causing the resin to assume a cellular structure.
FormicaŽ
The trademark for a thermosetting plastic usually used in
transparent or printed sheets as a chemical-proof and heat-proof
covering for furniture. forming A process in which the shape
of plastic pieces such as sheets, rods, or tubes is changed
to a desired configuration. The use of the term forming in
plastics technology does not include such operations as molding,
casting, or extrusion, in which shapes or articles are made
from molding materials or liquids.
Freeform Fabrication (FFF)
A synonym for rapid prototyping. The term is more precise
and wider in scope, and somewhat favored by the academic community.
One variant is freeform manufacturing (FFM), but a more common
one is solid freeform fabrication (SFF).

Fused Deposition Modeling (FDM)
A thermoplastic extrusion-based rapid prototyping technology
provided by Stratasys.
Fused Deposition of Ceramics (FDC)
Fused deposition modeling using a composite material of thermoplastic
or other binder containing ceramic particles or fibers.
Future-Proof
To create a product that won't be made obsolete by the next
wave of technological advancements.
