It is always possible to obtain tailored and enhanced mechanical/functional properties through the design of the cell spatial configuration and beam diameters [4].
In particular, compression tests were carried out on the fabricated lattice structures, and the influence of specific geometric factors (i.e., beam diameter, number of cells and cell rotation angle) on the mechanical performance was analysed.
Based on the results reported in the literature [4], the cell size and the beam diameter should be surely considered important factors.
The mechanical properties (e.g., the compliance and, hence, the crushing behaviour) were clearly influenced by the rotation angle as it affects the density distribution.

Introduction The fine-blanking die is easy to generate fatigue failure under the action of high contact pressure, furious friction and alternating loads in the process of stamping[1].Many high-tech fine-blanking enterprises select thepowder-metallurgy high-speed steel(PMHSS)to manufacture high level dies because of its good mechanical properties[2].
The two kinds of steels are usually used for fine-blanking punch-die.Few studies on the materials properties of the two kinds of steels are reported.
The properties of surface layer created in grinding influence the functional properties of the tooldirectly, such as fatigue strength and corrosion resistance, etc[3-5].
It is shown from range analysis that n is the most important factor, followed by Vx,Vy and ap.

Bulk density and moisture content are factors that significantly affect the physical properties of autoclaved aerated concrete (AAC) including thermal conductivity and other thermo-technical characteristics.
The thermo-technical properties were measured using the ISOMET 2104, a portable measuring device.
Introduction Bulk density is the factor that affects all physical properties of every material, including autoclaved aerated concrete (AAC).
Properties of materials are affected not only by total porosity bat also by pore size distribution.
In praxis, however, the materials always have a certain moisture content which causes impairment of its thermo-technical properties.

The factors that affect the surface quality and relative density are the process parameters such as the laser energy, scan speed and so on.
Due to the parts’s complexity and the unconventional process of SLM there is still a requirement to investigate the factors that affect precision including surface roughness and properties using SLM [8].
Surface roughness and part resolution are all heavily depend on laser processing parameters and melt pool control because properties of manufactured parts depend strongly on each single laser-molten track and each single layer [9].
Due to the layer based principle of generative production techniques there are certain restrictions like mechanical anisotropy and structural properties [10].

Mechanical properties Tensile test at room temperature was conducted on SANS WE600 hydraulic universal test machine, the results of which were shown in Table. 3.
It was obvious that, ①the mechanical properties of two steels tested both met the requirements, with a large strength surplus; ②the elongation of 2# steel was larger than 1# steel.
The mainly factors affecting the yield strength of steels were as follows [3]: large precipitation, inclusion, band shaped structure, the content of pearlite, the size and homogeneity of grain, and steel surface condition.
Large precipitation of liquid chromatography TiN formed in steel led to local stress concentration, becoming nucleation resources, thereby resulting in a decrease of mechanical properties.
The mechanical properties of both two steels met the requirements.
