“…To understand the effects of 3D printing using the FDM method, we briefly present the configuration and standardization steps for the desired print. The 3D printing process commences with creating a design of the 3D object in Computer‐Aided Design (CAD) software, such as Fusion 360® 70 . The resulting three‐dimensional model is converted into a file format that represents it through triangular geometric segments.…”

“…This file is subsequently processed by software known as “slicers,” responsible for dividing the 3D object into individual layers, a procedure called slicing. Using “slicer's software,” such as Cura 3D®, 70 the parameters can be configured, including the object's orientation, contour details, filament deposition width (also known as raster), the gap between deposited filament and contour, filament spacing within layers, and more 71 . An additional critical parameter to consider is the geometric shape and the orientation of the infill, which are determined by the raster's angle.…”

Additive manufacturing, which has become popular in recent years, is the process of joining materials through the deposition of layers to form parts based on data from a 3D model and fused deposition modeling. The search for biodegradable materials for the production of filaments for 3D printing is increasing and opening up possibilities for the development of new sustainable products, including the use of lignocellulosic waste in the formulation. Therefore, the present work aims to develop polymeric filaments based on polybutylene adipate terephthalate and low content (2.5 and 5 wt%) of peanut and soybean shells and evaluate their potential for 3D printing. The charges were characterized in terms of chemical composition. Tensile and dimensional variation tests were performed on samples manufactured from two different filling orientations: −45/45° and 0/90°. The printability of the filament was based on the manufacture of prototypes of agricultural tubes that were also characterized by thermogravimetry and their morphology through scanning electron and optical microscopy. Both natural residues significantly (p < 0.05) affected the sample dimensions and mechanical properties. However, the filling orientation difference was insignificant (p > 0.05). The filaments produced showed good processability, thermal and dimensional stability. The samples produced showed a satisfactory surface finish without exposing load agglomerates. These results demonstrate the feasibility of using lignocellulosic fillers, such as peanut and soybean shells, in additive manufacturing and indicate the possibility of producing parts with varied geometries.Highlights Use of lignocellulosic residues in biodegradable filaments. The filament produced with fillers of peanut and soybean shells showed good processability. Filament fracture depends on the raster angle. It was possible to produce tubes with good surface quality and mechanical properties.

Energy is one of the primary foundations supporting evolutionary changes. Heat transfer is improved by increasing the surface area density and/or changing the base fluid characteristics. Because of its small size and improved heat transfer properties, nanofluid cooled microchannel heat sinks (MCHS) have lately become a popular choice for electronics and thermal applications. The influence of employing nanofluids for cooling a chip was investigated experimentally in this work to evaluate the heat transfer characteristics. The investigations were carried out in order to confirm the influence of nanofluid concentration and wall temperature upon thermal-hydraulic properties of the microchannel heat sink. In present study, Al2O3 water nanofluid was employed, with 0.1, 0.2, 0.3, 0.4, and 0.5% nanoparticle volume fractions, mass flow rate (MFL) 2, 5, and 8 m/s at 25, 30 and 35oC inlet tempreture. The resulting experimental findings was verified from results obtained by other researchers, which showed important correlation. The heat transfer efficacy of electronics cooling systems has been enhanced by the nanofluid technology and the configuration of the rectangular heat sink.

In this study, the effect of printing direction on the tensile properties of polycarbonate (PC) parts produced using a 3D printer was investigated. A total of 9 samples were produced with printing directions of 0°, 45° and 90° with infill density of 20%. Tensile tests were carried out to determine the maximum tensile strength (UTS) of the samples. As a result of the research, it was determined that the samples produced in the same direction as the tensile direction (0° printing direction) had the highest strength values; on the other hand, samples produced in the 90° printing direction have the lowest strength values. While the ultimate tensile strength values for samples produced in 0° printing direction were measured respectively as 22.4 MPa, 21.6 MPa and 20.7 MPa; as 7.1 MPa, 9.1 MPa and 9.2 MPa in 45° printing direction; it was determined as 7.2 MPa, 5.4 MPa and 5.8 MPa in the 90° printing direction. In addition, UTS/mass ratios were calculated by measuring the mass of the samples after the tensile test. According to the results obtained, samples in the 0° printing direction have the highest UTS/mass ratio compared to other printing directions, making them the most durable option for applications requiring lightweight structures. Tensile samples produced in FDM were analyzed with the finite element method (FEM) and analysis results were found to be equivalent to physical tests. This study contributes to examination of the influence of 3D printing direction, especially exposed to tensile, on material properties, and provides important information for the production of lightweight and high strength PC components in industries such as medicine, aerospace and automotive.
