Abstract
The growth in adoption of additive manufacturing processes, such as the Fused Filament Fabrication (FFF) process, as alternative to traditional subtractive manufacturing processes, has been perceived for industrial and end-consumer applications. The FFF process, also known as 3D printing, deals with the fabrication of parts by adding subsequent layers of fused plastic filaments. The manufacture of the first layer in the FFF process is considered to be critical, due to the fact that the first layer provides support for the upcoming ones. Thus, if a defect is detected in the fabrication of the first layer, the FFF process can be interrupted. This practice may result in the prevention of several losses due to an incorrect printed part. It is a common practice in FFF monitoring studies to print what is called a monolayer part. A monolayer part is usually a fabrication of a part consisting of a single layer, but it can also be determined to be the fabrication of just the first layer of a multilayered part. Optical profilometry is a well-known method of inspecting the surface quality of parts obtained by different manufacturing processes. Thus, the present work sought to study the feasibility of evaluating the surface quality of monolayer parts obtained by the FFF process by means of optical profilometry for failure detection purposes. The obtained results showed the feasibility of using optical profilometry to inspect the surface quality of monolayer parts obtained by the FFF process for failure detection purposes.
