Abstract
Presented is the breaking strength test of specimens printed in FDM (fused deposition modeling) technology with different filling density, of PLA and PET materials: combined with each other. The aim of the study is to investigate the influence of technological parameters on the strength parameters of the produced object and to compare specimens printed of two materials simultaneously with those made of a single material.
Highlights
The 3D model has been modeled in SolidWorks
Plastic usually in the form of a wire wound on a reel - is taken into the header where it is heated to the melting point and extruded through a die [1, 2]
The 3D printers allow the production of models with different materials: plastic and composites
Summary
Presented is the breaking strength test of specimens printed in FDM (fused deposition modeling) technology with different filling density, of PLA and PET materials: combined with each other. The aim of the study is to investigate the influence of technological parameters on the strength parameters of the produced object and to compare specimens printed of two materials simultaneously with those made of a single material. The most common technology is FDM (fused deposition modeling), which consists in building a model by applying a melt-layer plastic layer, bonding previously applied layers. The 3D printers allow the production of models with different materials: plastic and composites. In incremental technologies ( FDM), the direction of application of the material is important, which determines the strength properties of the print in different planes. Temperature and print speed are influenced by the model's strength
