Abstract

Over the last decades, 3D printing has become more and more highly used in the production of various parts and prototypes. There are several technologies employed for 3D printing. Of these, the most widely spread and most affordable is probably the FDM (Fused Deposition Modelling) technology, which permits the use of various thermoplastic polymers to create 3D geometries by melting the material and deposing it in thin layers. Technical advances in latest years made 3D printers widely available and affordable. It is therefore of interest to investigate the properties of parts manufactured using the simplest of printers and the most usual materials. The present paper presents experimental investigations conducted regarding the influence of the printing regimes on the surface properties in 3D printed parts. Various printing parameters, such as extruder temperature, print speed and layer thickness were varied for the same part. Printing was done using a general purpose printer with a delta bot structure. The parts investigated in the present study were made using a generic PLA (poly-lactic acid) filament. Surface properties were then investigated optically by aid of a confocal microscope. Using the microscope’s dedicated analysis software, surface micro-topography was investigated and its parameters, obtained in accordance to ISO 4287 and ISO 25178, were analyzed.
