Formation of the database using the results of mechanical testing of the samples obtained by additive technologies

Abstract

We present methodological developments and approach to the formation of the database proceeding from the results of mechanical tests of the samples obtained by Fused Deposition Method (FDM) on a Fortus 380 mc 3D-printer using ABS-plastic. The material of 3D-printed structures reveals a natural anisotropy of the mechanical characteristics which are to be studied prior to developing of the mathematical models. Such studies are always limited by the goals and capabilities of researchers, on the one hand, but, on the other hand, they are aimed at sharing and integrating of the results obtained by various research groups. The accumulated data provide the opportunities for in-depth study and understanding of the general patterns and features of deformation of the materials obtained by additive technologies. Therefore, the data on their mechanical testing and processing should be available in the open (or limited) access. Data of standard tests for three-point bending of the samples that differ in the orientation of deposited layers considered together with the initial data and documents, the developed test program and data the final report were used to form a desired database. Formation of this database is an example that demonstrates an approach to arranging the scientific data which implements the key principles of data availability. The developed approach provides the possibility of structuring complex data sets keeping an independent access to each of the objects. The generated database is available at https://od.ict.sc/DuPXcR.
