Special Issue Information

Dear Colleagues,

New trends of international development require the creation and implementation of new technologies that will make it possible to introduce new products in new prospective markets. Additive manufacturing (AM), due to its high potential for forming complex shapes in an almost unrestricted manner, allows the production of individualized products and fully functional parts for a wide range of engineering materials, including components used in challenging operating conditions (thermal, mechanical, and corrosive environment). Research in additive manufacturing (AM) of metals has witnessed a dramatic rise in global attention during the past decade.

Despite the extensive work that has been completed on the properties of metal AM materials, there is still a need for a robust understanding of processes, challenges, application-specific needs, and considerations associated with these technologies. Therefore, this Special Issue covers these topics and focuses on to present a comprehensive review of the most common metal AM technologies, an exploration of metal AM advancements, and industrial applications for the different AM technologies across various industry sectors.

Within this context, this Special Issue aims to provide an opportunity for researchers to submit high-quality comprehensive reviews, original research papers and technical case studies in the field of metal additive manufacturing. Specific topics include but are not limited to:

  • Metal AM process, such as Powder bed fusion, binder jetting, direct energy deposition, Electron beam, and other customized and novel processes
  • Hybrid-AM techniques
  • Process parameter optimization
  • Microstructure characterization/defects–mechanical property relationships
  • Post-build/in situ treatments (HIP, HT, machining, shot peening, hybrid manufacturing, etc.) and their influence on material properties and final quality
  • Development of alloys/materials customized for AM and multi-material metal AM
  • Innovative and new applications of metal AM parts
  • Design for metal AM utilizing advanced morphologies (topology optimization process, architected materials, lattices, etc.) to enhance parts functionality and mechanical behavior

The study refers to the application of numerical modeling for the improvement of the currently realized precision forging technology performed on a hammer to produce connecting rod forgings in a triple system through the development of an additional rolling pass to be used before the roughing operation as well as preparation of the charge to be held by the robot’s grippers in order to implement future process robotization. The studies included an analysis of the present forging technology together with the dimension–shape requirements for the forgings, which constituted the basis for the construction and development of a thermo-mechanical numerical model as well as the design of the tool construction with the consideration of the additional rolling pass with the use of the calculation package Forge 3.0 NxT. The following stage of research was the realization of multi-variant numerical simulations of the newly developed forging process with the consideration of robotization, as a result of which the following were obtained: proper filling of the tool impressions (including the roller’s impression) by the deformed material, the temperature distributions for the forging and the tools as well as plastic deformations (considering the thermally activated phenomena), changes in the grain size as well as the forging force and energy courses. The obtained results were verified under industrial conditions and correlated with respect to the forgings obtained in the technology applied so far. The achieved results of technological tests confirmed that the changes introduced into the tool construction and the preform geometry reduced the diameter, and thus also the volume, of the charge as well as provided a possibility of implementing robotization and automatization of the forging process in the future. The obtained results showed that the introduction of an additional rolling blank resulted in a reduction in forging forces and energy by 30% while reducing the hammer blow by one. Attempts to implement robotization into the process were successful and did not adversely affect the geometry or quality of forgings, increasing production efficiency. Full article
