Introduction In recent years, along with the comprehensive application of computer graphics, computer engineering and pattern recognition etc., research on reverse engineering, intelligent robot and digital terrain etc. fields has gained further development.
In reverse engineering, the geometry data of complex parts are mainly acquired by 3D laser scan technology, and the data acquired in the beginning are scatted point cloud.
Such method relates point cloud processing with engineering calculation, but the selection of initial surface is not easy.

Introduction Powder Metallurgy (PM) engineering starts to use a new possibility of design controlled by the new technologies, led by additive manufacturing (AM), ultrasonic-assisted compaction or/and sintering, severe plastic deformation (SPD) and it has a huge potential to disrupt current manufacturing process processing.
Mainly AM is to take care of a forum demonstrating the depth and breadth of the research and development activities through manufacturing technology which most describes that goal [1-4].
Critical to further advances in this topic, will be the systematic study of the influence of important AM variables.

The porosity (void caused by technological reasons) in engineering materials always decrease their mechanical characteristics and usually affects the deterioration of the functional mechanical characteristics of the finished products.
Previous tests elaborated by the authors [2,18] show that such „hydrogen” models are represented in other systems such as Calcosoft Porosity and Procast Advance Porosity Module.
