Purpose The purpose of this study is to develop a low-cost and efficient method for 3D printing CuSn15 bronze alloy parts using pneumatic extrusion system. By avoiding complex processes such as filament preparation solvent/catalytic debinding, the aims streamline production process metallic components while maintaining high mechanical performance. research also seeks evaluate effects different sintering temperatures times on properties printed parts. Design/methodology/approach A simple cost-effective system was designed print metal paste containing powders. prepared by manually mixing powders, carboxymethyl cellulose distilled water. were subsequently dried sintered at various these parameters material properties. Tensile test scanning electron microscope analysis conducted assess structural integrity performance samples. Findings found that enabled successful without need processes. Increasing temperature led improved decreased porosity. time 820 °C reduction in demonstrated significantly influence porosity Originality/value This introduces novel approach system, eliminating traditional debinding provides new insights into effect additively manufactured simplifying process, offers low-cost, producing complex-shaped components, potentially expanding applicability industries electronics, marine engineering.

Digital light processing (DLP) is widely used in ceramic additive manufacturing, but it difficult to form metal materials, and related research the infancy. On one hand, slurries are cure under ultraviolet light. other mechanical properties functionalities of materials after debinding sintering require precise process regulation ensure. In this paper, geometric accuracy, tribocorrosion AISI 316L prepared by DLP (DLP-316L) systematically evaluated. The dimensional error formed part can be controlled within ± 70 μm, surface roughness on exposure plane only 1.6 μm. relative density DLP-316L 95.9 %, its microstructure includes austenite a small amount M7C3-type carbides at grain boundaries. It not has high ultimate tensile strength 543.5 2.5 MPa, more importantly, fracture elongation reach 58.73 2.55 which level preparation using DLP. addition, performance 3.5 wt. % NaCl solution better than that commercial rolled (R-316L). This mainly attributed presence high-hardness M7C3 microstructure, improves wear corrosion resistance material.

Fused filament fabrication (FFF) is the most widespread and versatile material extrusion (MEX) technique. Although powder-based systems have dominated metal 3D printing landscape in past, FFF’s popularity for producing parts (“metal FFF”) growing. Metal FFF starts from a polymer–metal composite feedstock proceeds through three primary stages, namely shaping (i.e., printing), debinding, sintering. As critically discussed present review, final quality of influenced by characteristics feedstock, such as loading, polymer backbone, presence additives, well processing conditions. The literature shows that diverse array metals, including steel, copper, titanium, aluminium, nickel, their alloys, can be successfully used FFF. However, formulation appropriate binders represents hurdle to adoption new systems. Meanwhile, intricate geometries are difficult fabricate due FFF-related surface roughness sintering-induced shrinkage. Nonetheless, comparison with other common AM techniques conducted herein suggests convenient option, especially prototyping small-scale production. Whilst providing insights into functioning mechanisms FFF, review offers valuable recommendations, facilitating broader uptake across various industries.
