Practice of Manufacturing Complex Filter Structures of B148 C95800 Nickel Aluminum Bronze Using 3D Printing Technology

I. Introduction

B148 C95800 NICKEL ALUMINUM BRONZE is a material with excellent mechanical properties and corrosion resistance. It is widely used in fields such as marine engineering and chemical equipment. Traditional manufacturing methods face numerous challenges when producing complex filter structures, such as high mold costs, great processing difficulties, and long production cycles. The emergence of 3D printing technology has provided new ideas for solving these problems. It can directly fabricate complex three-dimensional structures from digital models without the need for traditional molds, which greatly shortens the production cycle, reduces costs, and enables the realization of complex designs that are difficult to achieve with traditional manufacturing methods.

II. Overview of 3D Printing Technology

3D PRINTING TECHNOLOGY CONSTRUCTS THREE-DIMENSIONAL SOLID MODELS BY ADDING MATERIALS LAYER BY LAYER. It has the advantages of high design freedom, high production efficiency, high material utilization rate, and good quality consistency. When manufacturing the filter structures of B148 C95800 NICKEL ALUMINUM BRONZE, the selective laser melting (SLM) technology has become the first choice due to its high precision and high strength characteristics.

III. Practice Process
(1) Design Stage
Use CAD software to design complex three-dimensional filter structures, consider parameters such as pore diameter, porosity, and thickness, and optimize the design of support structures to adapt to the 3D printing process.

(2) Printing Stage
• Material Selection: Select B148 C95800 NICKEL ALUMINUM BRONZE powder and ensure that its particle size distribution and purity meet the requirements.
• Parameter Optimization: Determine the optimal combination of laser power, scanning speed, and layer thickness through experiments to ensure printing quality and performance.
• Process Monitoring: Monitor the printing status in real time to avoid problems such as laser deviation and powder splashing.

(3) Post-processing Stage
• Removal of Support Structures: Use machining or chemical etching methods to remove the support structures.
• Surface Treatment: Improve the surface quality of parts through sandblasting, polishing, or electroless plating.
• Heat Treatment: Optimize heat treatment parameters to improve the strength and toughness of parts.
