LMDS accumulates metal powder materials according to two-dimensional profile information one layer off another, and finally the three-dimensional solid parts are formed in substrate, with the laser cladding method.
The metal material of both the clad and substrate are TC4 (Ti-6Al-4V).

The porosity parameter has a significant influence on the strength and performance of materials and therefore the estimation of porosity is of interest across several fields like biomedical engineering, materials engineering and civil engineering [2-5].
Many applications in the fields of material science and medicine benefit from this.

In this life cycle, the raw materials are processed into products, products purchased through the circulation of exchange become commodity, and the commodity become waste after people using them, and the waste can be reused as secondary products.
The product disassembly can make the usable parts directly into new product assembly field, through the waste materials into new material degradation and raw material processing program.
For producers, green design is mainly about saving raw materials, simplifying manufacture process, reducing the manufacturing cost through specific design and of course, it has to consider saving the use-procedure and use-cost of the users.
Most of the packaging materials would last for a long time even a hundred years to be decomposed, and so people has to bury or burn them, which brings tremendous damage to the environment.
