| Summary: | The manufacturing of machine parts with additive methods (AM) is of significant importance in modern industry.
The development of 3D printers and all 3D printing technology is impressive. The ability to make parts quickly
and relatively cheaply with AM gives excellent opportunities in terms of e.g., shortening the production preparation time. Proper selection of printing parameters allows for a significant reduction of printing time and production
costs. Unfortunately, this has different consequences. Due to the course of the printing process and the parameters
that can be set, the same product produced with different parameters has different mechanical properties – mainly
different strength. This paper presents the impact of 3D printing parameters on the strength of manufactured parts.
Strength tests were carried out on samples made in accordance with DIN EN ISO 527-1:2019. The samples were
printed in technology FDM from three different materials, i.e. PLA (completely biodegradable), PETG (recycled
material) and Smart ABS (material with minimal shrinkage). The tested samples were made in three levels of print
filling – 10, 30 and 60% and with different types of filling – line, mesh and honeycomb. A series of static tensile
tests were carried out to determine the strength of the samples produced with different printing parameters. Thanks
to the obtained test results, it is possible to select the optimal printing parameters depending on the forecast load
of the manufactured parts. |
