Process capability analysis of fused deposition modelling for plastic components
Abstract
Purpose
The purpose of the present study is process capability analysis of fused deposition modelling (FDM) process as rapid pattern making (RDPM) solutions for plastic components.
Design/methodology/approach
Starting from the identification of component, prototypes with ABS plastic material were produced and dimensional measurements were made with coordinate measuring machine (CMM). Some important mechanical properties were also compared to verify the suitability of the components.
Findings
The study highlighted the best settings of orientation, support material quantity for the selected component as a case study on FDM machine from dimensional accuracy and economic point of view as RDPM solution for plastic components.
Practical implications
This process ensures rapid production of statistically controlled pre-series technological prototypes and proof of concept at less production cost and time. Final components produced are acceptable as per ISO standard UNI EN 20286-I and DIN16901.
Originality/value
The results of the study suggest that FDM process lies in ±4.5 sigma (σ) limit in regard to dimensional accuracy of plastic component is concerned and may be gainfully employed as RDPM solution for bio-medical applications.
