Special Issue Information

Dear Colleagues,

One of the major issues of additive manufacturing (AM) today is the development of novel AM technologies using advanced materials to expand scientific and industrial applications. The part quality, which depends on AM technologies, is greatly influenced by applied AM processes, deposition methodologies, and post-processing techologies. Numerical analyses, including heat transfer and residual stress analyses, are needed to create desired parts without defects using the AM process. The application of the AM process using advanced materials can improve functionality and desired characteristics of the product.

Therefore, this Special Issue shall focus on recent works related to additive manufacturing technologies and their applications using advanced materials. Topics can include but are not limited to:

  1. Additive manufacturing process using advanced materials;
  2. Post-processing technology of AM parts (including heat treatment and microstructure modification, etc.);
  3. Application of AM technology to improve functionality of parts;
  4. Application of AM technology using advanced materials;
  5. Numerical analysis of additive manufacturing process for metallic and non-metallic materials;
  6. Review of AM technologies and their applications using advanced materials.

Deposition of Durable Micro Copper Patterns into Glass by Combining Laser-Induced Backside Wet Etching and Laser-Induced Chemical Liquid Phase Deposition Methods

Glass is a well-known non-conductive material that has many useful properties, and considerable research has been conducted into making circuits on glass. Many deposition techniques have been studied, and laser-induced chemical liquid phase deposition (LCLD) is a well-known and cost-effective method for rapid prototyping of copper deposition on glass. However, the deposition results from the LCLD method on the surface of glass, which shows an issue in its detachment from the substrates because of the relatively low adhesion between deposited copper and the nontreated glass surface. This problem undermines the usability of deposited glass in industrial applications. In this study, the laser-induced backside wet etching (LIBWE) method was performed as a preceding process to fabricate microchannels, which were filled with copper by LCLD. Additional durable copper wire was produced as a result of the enhanced adhesion between the glass and the deposited copper. The adhesion was enhanced by a rough surface and metal layer, which are characteristics of LIBWE machining. Furthermore, the proposed method is expected to broaden the use of deposited glass in industrial applications, such as in stacked or covered multilayer structures with built-in copper wires, because the inserted copper can be physically protected by the microstructures.

A real-time, accurate, and reliable process monitoring is a basic and crucial enabler of intelligent manufacturing operation and digital twin applications. In this study, we represent a novel vibration measurement method for workpiece during the milling process using a low-cost nanoparticle vibration sensor. We directly printed the vibration sensor based on silver nanoparticles positioned onto a polyimide substrate using an aerodynamically-focused nanomaterials printing system, which is a direct printing technique for inorganic nanomaterials positioned onto a flexible substrate. Since it does not require any post-process such as chemical etching and heat treatment, a highly sensitive vibration sensor composed of a microscale porous structure was fabricated at a cost of several cents each. Furthermore, accurate and reliable vibration data was obtained by simple and direct attachment to a workpiece. In this study, we discussed the performance of vibration measurement of a fabricated sensor in comparison to a commercial vibration sensor. Using frequency and power spectrum analysis of obtained data, we directly measured the vibration of workpiece during the milling process, according to a process parameter. Lastly, we applied a fabricated sensor for the digital twins of turbine blade manufacturing in which vibration greatly affects the quality of the product to predict the process defects in real-time.
