3D Printer Operational Robustness on Polylactic Acid based Product Printing

“…There is not even a single measurement combination in which Diameter 1, Diameter 2 and Diameter 3 reach a minimum of 35mm. The ability of 3D printers technology to produce accurate nominal dimensions an all directions still needs to be addressed [1], [7], [11].…”

“…3D printers are the output of Industry 4.0 [1]. It is widely used in product prototyping, 3D modelling, and production.…”

“…3D printers are proven to be effective at reducing production errors and optimizing product development time [2], [3]. 3D Printing or additive manufacturing creates physical objects from a geometrical representation by successive addition of material (ISO/PRF 17296-1, 2015) [1], [3], [4]. In general, 3D printer output quality may vary in different geometries [1], [5]- [8].…”

“…3D Printing or additive manufacturing creates physical objects from a geometrical representation by successive addition of material (ISO/PRF 17296-1, 2015) [1], [3], [4]. In general, 3D printer output quality may vary in different geometries [1], [5]- [8]. This is due to the limitations of the 3D printer's intelligence in translating a Numerical Control (NC) program, in which there are various combinations of coordinate positions, geometric movements (X,Y, and Z directions), and 3D printer pre-processing parameters that are set manually [9].…”

“…There are also significant differences between the various 3D printing technologies and processes in terms of suitable materials [1], [2], [5], [7], [9], [11]. Fused Deposition Modelling (FDM) technology is one of the most popular 3D printing technologies [2], [6], [7], [11].…”
