粉末锻造零件通常不像冷挤压和烧结零件那样接近最终尺寸或形状。
Powder forged parts generally are not as close to final size or shape as cold pressed and sintered parts.
烧结零件可以实现尺寸控制，因为注塑密度明显均匀，所以烧结收缩也是均匀的。
Dimensional control can be exercised on the as-sintered component as the injected density is sensibly uniform so shrinkage on sintering is also uniform.
结果表明，分形扫描路径能有效降低薄层中的残余拉应力，可望提高烧结零件的机械强度。
It indicated that: the fractal scanning path can reduce the layer's residual stress effectively, it is hopeful to advance the part's mechanical intensity.
