  Additive Manufacturing (AM) is gaining renewed popularity and attention due
to low-cost fabrication systems proliferating the market. Current communication
protocols used in AM limit the connection flexibility between the control board
and peripherals; they are often complex in their wiring and thus restrict their
avenue of expansion. Thus, the Controller Area Network (CAN) bus is an
attractive pathway for inter-hardware connections due to its innate quality.
However, the combination of CAN and AM is not well explored and documented in
existing literature. This article aims to provide examples of CAN bus
applications in AM.
