“…The use of such technologies for technical connections is diffuse in the field of technology (Gonzalez-Quintial, 2022) (Senbin Huang, 2021) (Jaradat, Soliman, & Taha, 2023) (Gilibert, Mesnil, & Baverel, 2022) (Song, 2022) (Hamilton, et al, 2022) . The advantages for joint production are as follows: faster execution in solving increasingly complex geometries and optimizing material consumption.…”

This research examines students' experimentation skills in the field of digital fabrication for the development of construction joints. The architecture students in charge of the experiment had no previous experience with digital fabrication technologies. However, with specific lessons and the optimization of digital design tools commonly used in their studies, such as CAD software, they were able to achieve results that were useful in understanding the design and production processes of this technology. Ten local FabLabs, maker spaces, and woodworking shops were involved in the manufacturing process. The CNC machines used are those available from the manufacturer partners and represent the most commonly used types: FDM, laser cutter, and miller cutter. The aim of this research is to investigate the accessibility of design and production processes for digital fabrication joints using only the tools that are commonly employed by local manufacturing companies.

“…For example, 2 of 12 during the process of fabricating structurally layered soft magnetic Fe-Si components, insufficient air gaps increase the risk of parts unintentionally adhering to each other due to their close proximity [21]. Shape optimization techniques can help overcome these challenges, ensuring minimized core loss and optimizing the final product's performance [21][22][23]. Nevertheless, constraints related to wall thickness remain a significant hurdle, especially in high-density additive manufacturing.…”

Additive manufactured interlocking structures often face challenges in achieving suitable joinability due to thermal deformation. This issue becomes particularly interesting when fabricating structures that require high density but not fully connected layers, such as soft-magnetic materials. This study focuses on systematical investigation of the deformation as a function of finger thickness and building direction in model interlocking structure. In the perpendicular direction to the build plate, the distortions of joint part were significantly reduced due to lower thermal stress. In addition, the effect of laser power and scan speed on interlocking structure are systematically discussed. Additionally, through stress and thermal simulations of additive manufacturing process, it was confirmed that the compensated model can enhance the joinability of interlocking structures. These findings contribute to the development of optimal design for additive manufactured parts of soft magnetic materials such as stators in electric motor components, which needs insulations and density.
