Effective Thermal Conductivity Measurement of Additively Manufactured Lattice Structures by Application of Modified Temperature Profile Method

“…The thermal conductivity of the sample 𝑘 𝑒𝑥𝑝 is obtained from the temperature rise from the surroundings of the upper and lower carriage blocks 𝑇 𝑈𝐶 , 𝑇 𝐿𝐶 and the heat flow at the upper and lower rods 𝑄 𝑈𝑅 , 𝑄 𝐿𝑅 . By obtaining a linear gradient from the measured temperature values of the upper and lower rods using the least-squares method, 𝑄 𝑈𝑅 and 𝑄 𝐿𝑅 are obtained from equation (1).…”

“…Where 𝑘 𝑅 denotes the thermal conductivity of the rod, 𝐴 𝑅 denotes the cross-sectional area of the rod, and (𝑑𝑇/𝑑𝑥) denotes the temperature gradient at the rod. The amount of heat flow through the upper rod 𝑄 𝑈𝑅 is calculated from the temperature gradient of the upper rod (𝑑𝑇/𝑑𝑥) 𝑈𝑅 and the amount of heat flow through the lower rod 𝑄 𝐿𝑅 is calculated from the temperature gradient of the lower rod (𝑑𝑇/𝑑𝑥) 𝐿𝑅 from equation (1). Using the amount of heat flow at the upper and lower rods, and assuming that (𝛥𝑇 𝑠 /𝛥𝑥 𝑠 ) is the temperature gradient of the sample, the effective thermal conductivity 𝑘 𝑒𝑓𝑓 of the sample can be calculated as follows:…”

“…Additive manufacturing technology enables the design of structures with high-performance multifunction that are not bound by conventional designs and is bringing about a major revolution in manufacturing. The use of additive manufacturing technology is already expanding in aerospace, medical, and other fields and is expected to attract even more attention in the future [1][2] [3]. One of the new structures that can be fabricated using additive manufacturing technology is lattice structures, which are periodic patterns of nodes and beams or struts.…”

Enhancing Mechanical Properties of 3D Printing Metallic Lattice Structure Inspired by Bambusa Emeiensis

“…The design, fabrication, and performance of selective laser melting (SLM) lattice structures have been introduced. The data are summarized to analyze the reported mechanical performance of SLM lattice structures and provide insight into the bounds of their technical capabilities [ 18 , 19 ]. However, this kind of work belongs to the field of optimization design for 3D printing equipment.…”

Investigation of the Microstructure and Mechanical Properties of an Ultrahigh Strength Martensitic Steel Fabricated Using Laser Metal Deposition Additive Manufacturing

“…Additive manufacturing (AM) has attracted considerable attention in the field of machinery manufacturing due to its ability to make components layer by layer on the basis of a 3D-CAD volume model [1,2]. The advantages of this technology are that it is efficient, it avoids material waste, it reduces costs, and it overcomes the problems caused by traditional methods in manufacturing metal parts with complex shapes [3].…”
