RP 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

RP 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.)

2. The metallic powder is melted and sintered by
radiating laser beams. (The process 1. and 2. are

3. The contours of the modeling part are machined
with a cutter/cutters.
