Special Issue Information

Dear Colleagues,

Additive manufacturing (AM) is a technology that enables the creation of functional parts with design freedom, making it a popular choice in various industrial sectors. Recent advancements in AM techniques have opened up many opportunities in terms of reducing the materials used and fabrication costs. This is thanks to a reduced number of elements in industrial devices. AM techniques also enable the relatively easy production of complex geometries such as cellular solids, metamaterials, and biomimetic materials, many of which were once difficult to manufacture using conventional techniques. These objects can be fabricated from various metals and polymers using computer-aided design (CAD) models.

This Special Issue aims to collect high-quality papers from excellent young researchers and welcomes submissions on the additive manufacturing of elements with predicted microstructure and mechanical properties, the use of artificial intelligence/machine learning (AI/ML), numerical algorithms, and µ-CT imaging for quality control.

Despite the possibility of fabricating objects of any shape in one production step, AM manufacturing has some disadvantages. One of these is the requirement to generate support structures for the parts fabricated by various processes. Such support should dissipate the heat generated during the 3D-printing process, minimize the geometrical distortions induced by internal stresses, and support overhang structures. This Special Issue will cover computer simulations and improved fabrication protocols that address these issues.

During powder-in-bed AM processes, not all powder particles are melted, and therefore the removal of any unmelted particles needs to be performed with mechanical or chemical post-processing methods. This Special Issue is dedicated to various areas of research relevant to AM, including both polymer and metal. Processing parameters and post-processing methods (not limited to annealing and chemical modifications) are of particular interest. We also welcome submissions improving the design of materials through various AM techniques and modifications to commercial machines.

This Special Issue continues the series “Progress in Additive Manufacturing: Design, Fabrication and Post Processing”.

Coaxial wire-based laser metal deposition is a versatile and efficient additive process that can achieve a high deposition rate in the manufacturing of complex structures. In this paper, a three-beam coaxial wire system is studied, with particular attention given to the effects of the deposition direction and laser beam orientation on the resulting bead geometry symmetry. With the three-beam laser delivery, the laser spot pattern is not always symmetric with respect to the deposition direction. Single titanium beads are deposited in different directions and at varying deposition rates, and the bead profile is quantitatively scored for multiple symmetry measures. Through an analysis of variance, the deposition direction and deposition rate were found to be insignificant with respect to the resulting bead symmetry for the developed measures. The bead symmetry and geometry are important factors in determining if a build is free of critical defects, and in this study, it is shown that the three-beam coaxial wire deposition setup is a directionally independent process.
