Fused Deposition Modelling The FDM process forms three-dimensional objects from CAD-generated solid or surface models. A temperature-controlled head extrudes thermoplastic material layer by layer. The designed object emerges as a solid three-dimensional part without the need for tooling. http://www.stratasys.com
Fused Deposition Modeling is a type of rapid prototyping that is generally cheap than other processes like SLA and creates a model in many of the same materials (ABS etc) but usually has a lower resolution than other processes.
The subdivision of a transmission circuit into two or more separate circuits by splitting the frequency range of the circuit into narrow frequency bands.
The division of a transmission frequency range into narrower bands to create two or more channels, enabling each data source to have its own channel. In FDM, the multichannel transmission must emanate from a single location — unlike frequency division multiple access (FDMA), which enables the source data signals to emanate from multiple transmitters in different locations. See FDMA.
A multiplexing scheme in which the available transmission frequency range is divided into narrower bands. Each of these bands is used to carry a separate channel.
A technique of dividing the bandwidth of a communications line into multiple smaller units of bandwidth, each of which supports an independent information stream.
fdm is a simple, lightweight replacement for mail fetch, filter and delivery programs such as fetchmail and procmail. It can fetch using POP3 or IMAP or from stdin, and deliver to a pipe, file, maildir, mbox or SMTP server, based on regexps.
Finite Difference Method. An alternative method to discretize the partial differential equations that describe conservation of mass, momentum and energy. The advantage of the FDM is that it is easy to implement, but it is generally limited to rectangular geometry which cannot be multiply connected (e.g. no ribs or stiffeners). It has therefore been used a lot in scientific environments.
Forecourt Distribution Module. A board used to connect the forecourt devices, such as pumps and tanks to The Enabler card, providing the physical and electronic format to suit each manufacturer's equipment.
Fiber distribution module. Fiber distribution modules contain pre-connectorized and pre-tested fiber optic cables. These assemblies mount easily into traditional patch panels. FDM's provide a modular, compact, and organised fiber optic solution. See also: fiber optic assemblies See links to product page
