Difference Between FDM and FDMA. Frequency Division Multiplexing, or FDM, is a multiplexing technique for the physical layer that allows multiple low bandwidth signals to share the same high bandwidth frequency range. It is achieved by allocating a smaller frequency range to each signal that is using the same channel.
For exact specifications, refer to the product spec sheets. PolyJet and FDM machines offer build volumes ranging from 5 x. 5 x 5 inches ( 127 x 127 x 127 mm) to 39 x 31 x 20 inches (1000. x 800 x 500 mm), and they have comparable mid- and large-size. options.
