Abstract:
Failure Mode and Effects Analysis (FMEA) is a widely used tool for
identifying potential failure modes in a system, evaluating their effects, and
implementing measures to mitigate or eliminate them. In the case of a DIY 3D
printer, FMEA can be used to identify potential failure modes that could lead
to sub-optimal performance or even complete system failure. The FMEA
process involves identifying potential failure modes, determining their severity,
likelihood of occurrence, and detectability, and then prioritizing them based on
their risk priority number (RPN). This process can be used to identify potential
failure modes in various aspects of the 3D printer system, including
mechanical components, electrical components, electronics components, and
software. 3D printing is a rapidly evolving field. Particularly in the industrial
sector, this technology is expanding quickly. Even in the maritime sector, the
use of 3D printers in replacing several main machinery parts is now seeking
demand. Some successfully printed parts such as nozzles and valves are now
being recognized by the Classification Society. There is no denying that using
this technology in the industry has both benefits and drawbacks. Yet as time
passes, this technology's deficiencies continue to be corrected and it keeps
growing. Understanding modern technologies like 3D printing is therefore
highly beneficial. Knowing how well the printer is in excellent condition and
locating the printer issue that will result in the machine being underpowered
are some aims of the risk assessment. A risk analysis of printer failure is
essential to prevent failure while running the printer. The printer's durability will
occasionally decrease, and it is simple to destroy the internal components by
pushing them to perform harder than they can. Understanding the state of this
printer is the primary goal of risk assessment or risk failure analysis. Hence, in
this project, the DIY 3D printer failure risk assessment is conducted using
FMEA.
