6RP HSC Hybrid Process 1
1. The squeegee plate is moved from the right
side to the left by raising the material tank and
lowering the modeling tank to form metallic
powder layers.
Squeegeing
7RP HSC Hybrid Process 2
1. The squeegee plate is moved from the right
side to the left by raising the material tank and
lowering the modeling tank to form metallic
powder layers.
2. The metallic powder is melted and sintered by
radiating laser beams. (The process 1. and 2. are
repeated 10 times.)

lowering the modeling tank to form metallic
powder layers.
2. The metallic powder is melted and sintered by
radiating laser beams. (The process 1. and 2. are
