摘要

本文旨在研究选择性激光烧结技术制备的试样的力学特性。本研究涵盖了由PA12材料制作的弯曲试件。根据ISO 178标准选择CAD模型尺寸，所选试样几何尺寸为96 x 8 x 4 [mm]。所有标本均使用专用机器Fuse 1 (FormLabs, Summerville, MA)制作。制作了四个样品批次，每个批次具有不同的印刷方向(即垂直和水平)和印版上的位置(即在粉末床的中间和边缘)。样品测试使用岛津通用机器测试材料的机械特性，AGS-X 100 kN，与一个独特的附加工具测试三点弯曲样品。

The influence of printing orientation on the flexural strength of PA 12 specimens produced by SLS

This article aims to investigate the mechanical characteristics of specimens fabricated using Selective Laser Sintering technology. The research covers flexural specimens, produced by PA12 materials. CAD model dimensions were selected according to the ISO 178 standard, and the chosen specimen geometry is 96 x 8 x 4 [mm] in bulk. All specimens were produced using a specialized machine Fuse 1 (FormLabs, Summerville, MA). Four specimen batches were produced, each with a different printing orientation (i.e. vertical and horizontal) and location on the printing plate (i.e. in the middle and on the edge of the powder bed). The specimens are tested using a Shimadzu universal machine for testing the mechanical characteristics of materials, AGS-X 100 kN, with a unique additional tool for testing 3-point bending specimens.

期刊介绍： Science of Sintering is a unique journal in the field of science and technology of sintering. Science of Sintering publishes papers on all aspects of theoretical and experimental studies, which can contribute to the better understanding of the behavior of powders and similar materials during consolidation processes. Emphasis is laid on those aspects of the science of materials that are concerned with the thermodynamics, kinetics and mechanism of sintering and related processes. In accordance with the significance of disperse materials for the sintering technology, papers dealing with the question of ultradisperse powders, tribochemical activation and catalysis are also published. Science of Sintering journal is published four times a year. Types of contribution: Original research papers, Review articles, Letters to Editor, Book reviews.
