I will explain the production process of metal 3D printing [Hunminjeongeum edition 'Hun' ballpoint pen] in pictures.

1) Design a ballpoint pen in 3D.

2) Complete printing by melting and additive manufacturing with laser

3) The printed ballpoint pen removes the metal powder produced during additive manufacturing with a brush.

4) Remove impurities with compressed air and clean the surface with sand blister.

5) Heat treatment is performed in the oven to remove stress from the molten metal ballpoint pen.

6) Remove the support that was created for metal 3D printing.

7) Remove detailed impurities with a handpiece.

8) Smooth the surface of the metal ballpoint pen with a vibration barrell grinder.

9) The surface of cobalt chromium (CoCrMo), a raw material, is plated with 18K white and gold colors.
