| Abstract [eng] |
Fused filament fabrication (FFF) machines are increasingly being used by manufacturers and makers to produce parts for functional use. Apparently, the control of accuracy and surface finish quality becomes crucial for this technology. The goal of this study was to present an investigation of printing parameters on dimensional accuracy and determining the optimal surface finish of a part built by the Fused filament fabrication (FFF) process. Defined by the Design of Experiment (DOE) main factors for investigation were chosen: nozzle temperature (170°C and 230°C levels), feed-rate (50% and 100% levels) and nozzle diameter (from 0,25mm, 0,4mm, to 0,6mm). Experiments were conducted with these parameters and 12 test targets were printed and replicated. 2k statistic factorial design was used to analyze data and determine significant factors. Comparative analysis was used to verify geometrical and dimensional accuracy. |
