Background:

Fabricating complex three-dimensional (3D) metal microstructures presents significant challenges.
Existing methods often lack the precision or scalability required for intricate designs.

Purpose of the Study:

To propose and validate a hybrid manufacturing approach combining 3D printing and electroforming for metal microstructures.
To investigate the impact of key electroforming parameters on the quality of fabricated microstructures.

Main Methods:

A substrate with microstructures was first fabricated using 3D printing technology.
Electroforming was then employed to create the desired metal microstructures on the 3D printed substrate.
Systematic analysis of process parameters including current density, electrode distance, and pulse current duty cycle.

Main Results:

Optimal electroforming conditions were determined: peak current density of 6A/dm², a void ratio of 20%, and an electrode distance of 40 mm.
Successful fabrication of various microstructures was achieved using these optimized parameters.
The study provides a detailed analysis of parameter influence on the electroformed layer characteristics.

Conclusions:

The combined 3D printing and electroforming technique offers a viable method for producing intricate 3D metal microstructures.
Optimized electroforming parameters are crucial for achieving high-quality results in this hybrid manufacturing process.
This approach holds potential for applications requiring precise and complex metal components.
