Extrusion-Based 3D Printing of CuSn10 Bronze Parts: Production and Characterization

Abstract

The interest in producing cost-effective 3D printed metallic materials is increasing day by day. One of these methods, which has gained much attention recently, is the fused deposition modelling (FDM) method. The parameters used in the FDM method have significant effects on the printed part properties. In this study, CuSn10 bronze alloy was successfully produced. The printing speed and layer thickness were investigated as the printing process parameters, and their effect on morphological properties was characterized by using SEM. As a result, it was observed that the formation of printing-induced voids was prevented by applying a layer thickness of 0.2 mm. Additionally, by increasing printing speed, a slight decrease in product density was observed. Following determination of 3D printing parameters which give the highest printed part density, the parts were debound in hexane solution via solvent debinding. Finally, the parts were sintered at 850, 875 and 900 °C for 5 h to examine effect of sintering temperature on density, porosity, shape deformation and mechanical properties. Although partial slumping started to form over 875 °C, the highest density (94.19% of theoretical density) and strength (212 ± 17.72 MPa) were obtained by using 900 °C as the sintering temperature.

Advancements in Additive Manufacturing for Copper-Based Alloys and Composites: A Comprehensive Review

“…Only one study in the literature has investigated the 3D printing of tin-bronzes using extrusion-based AM (also known as fused deposition modeling or FDM) of CuSn10 parts [150]. In this AM method, metallic powders are mixed with polymeric binders to improve the viscosity of the feedstock material during the printing process [150].…”

Optimization of Process Parameters of Fused Filament Fabrication of Polylactic Acid Composites Reinforced by Aluminum Using Taguchi Approach

“…There are several advantages to using PLA raw filament in the FFF-based 3D printing process, including its biodegradability, ease of printing, eco-friendliness, nontoxicity, and low cost. Hence, this material can be found in a variety of applications, from kitchen utensils to medical implants [10][11][12]. Because of various restrictions, such as a limited processing window and low mechanical characteristics, their usage in the FFF technology has encountered challenges.…”
