High-Precision 3D Printing of Silicon Nitride U-Shaped Channels Using ADT-3D-ZP Series

Silicon Nitride (Si₃N₄) is a high-performance ceramic known for its exceptional hardness, strength, thermal stability, low density, and excellent thermal conductivity and electrical insulation. These characteristics make it a preferred material in industries such as aerospace, automotive, electronics & semiconductors, and medical devices.

However, silicon nitride is notoriously difficult to process using traditional machining. Adventuretech’s ceramic 3D printing technology provides a breakthrough solution for manufacturing complex Si₃N₄ geometries, such as U-shaped channels.

📌 Project Overview: Silicon Nitride U-Channel Printing

Our team used the ADT-3D-ZP Printer Series to successfully print a U-shaped silicon nitride channel with high precision and structural complexity.

🖨️ Printer in Use: ADT-3D-ZP

Printing was performed using the ADT-3D-ZP series, specifically designed for high-density ceramic slurry extrusion and precision shaping.

🧩 STL Model

Here is the STL model used in the printing process:

🔧 Print Process

The print process included precise extrusion path planning, layer-by-layer deposition, and structural support setup.

🧹 Post-Processing: Removal & Cleaning

After printing, the inner supports were carefully removed without damaging the main cavity structure. Cleaning was performed using a controlled flow system.

✅ Final Results

The final printed product exhibited excellent dimensional accuracy and a fully preserved internal cavity structure, showcasing the power of Adventuretech’s ceramic 3D printing.

This case study demonstrates the capabilities of our proprietary 3D printing equipment in processing complex silicon nitride structures with internal cavities and support-removal considerations.
