3D printing as a manufacturing method is gaining more popularity since 3D printing machines are becoming easily accessible. Especially in a prototyping process of a machine, they can be used, and complex parts with high quality surface finish can be manufactured in a timely manner. However, there is a need to study the effects of different manufacturing parameters on the materials properties of the finished parts. Specifically, this chapter explains the effects of six different process parameters on the impact resistance. In particular, print temperature, print speed, infill ratio, infill pattern, layer height, and print orientation parameters were studied, and their effects on impact resistance were measured experimentally. Moreover, the optimum values of the process parameters for impact resistance were found. This chapter provides an important guideline for 3D manufacturing in terms of impact resistance of the printed parts. Furthermore, by using this methodology the effects of different 3D printing process parameters on the other material, properties can be determined.

In this article it is proposed to increase the impact resistance of alloyed stamped steels during magneto thermal treatment without changing the hardness. Determination of the optimal technological parameters for magneto thermal treatment of steels 5ХНМ, ЗХЗМЗФ, 4Х5МФС, 4Х5В2ФС. It is recommended to increase the impact toughness when processing steel 4X5В2ФС with a cyclic magnet in the vertical direction of the samples during magneto thermal treatment.

The impact ductility of plain concrete and polymer-modified concrete with different p-c (polymer-cement) ratio were measured by bend-impact method. The impact-resistance of plain concrete and polymer-modified concrete were contrasted. The modified mechanism of polymer-modified concrete was analyzed. The results indicate that the impact ductility of concrete are increased with contents of polymer firstly and then reduced and the best p-c ratio is 15%. The test results also indicate that the concrete performance are modified by polymer, which prevent crack developing in microcosmic and improve impact ductility in macroscopic.
