Abstract

3D printing is one of the most progressive additive technologies today. It finds its application also in industry. In terms of mechanical properties, the printing design of the product is an important parameter. The presented study investigates the effects of the printing design of a thin-walled 3D polymer model on the mechanical properties of the model. The material used for printing was acrylonitrile-butadiene-styrene (ABS) and the 3D print method was Fused Deposition Modeling (FDM). ABS was tested at various die temperatures and with various printing designs at a constant 3D print speed and identical print bed temperature. We examined the effect of printing temperature and product printing design on the resulting mechanical properties. We compared theoretical and experimental results by CAE–FEM Advanced Simulation modules. Results tensile deformations at maximum load by experiment and simulations are comparable. The best results of testing the mechanical properties were found in the pattern printed at a 45° angle at temperature 285 °C.

Highlights

Fused Deposition Modeling (FDM) is one of the most popular 3D printing methods
The results show that the choice of FDM parameters makes it possible to achieve comparable mechanical properties with conventional methods of processing [33]
4 Conclusion Sample sets were prepared at five printing temperatures from 245 °C to 285 °C with a different product structure - a dogbone with a honeycomb 3D print structure, a structure 3D printed at 90° angle, and one 3D printed at 45°

Summary

Introduction

Fused Deposition Modeling (FDM) is one of the most popular 3D printing methods. The most widely used polymers that are used for this technique include ABS (the acrylonitrile-butadiene-styrene terpolymer) and PLA (polylactic acid) [13,14,15]. As their use in both commercial and non-commercial sectors is ever expanding, it is important to ensure obtaining required mechanical and thermal properties by proper selection of 3D print temperatures as well as the print bed temperatures, which have a great impact on the resulting product. The influence of surface and structure of 3D models on their mechanical properties was studied by numerous scientific groups [16,17,18,19,20,21]
