Development of a Novel Laser-Sintering Machine for Fabrication of Artificial Bone
To fabricate an artificial bone, the degradation rate of which is adjustable, porosity and pore size is controllable, and internal continuity is good, a device is developed with nano-sized hydroxyapatite as raw material, micron-sized spot of high-power laser as energy, and selective sintering as technology to fabricate three-dimensional porous. Its basic composition, design ideas, features and working principle are introduced. The feeding mechanical system, sintering system, and laser focusing system are described in detail. The motion precision and laser-spot control precision meet with the requirements with testing.
