Research on Application of SLA technology in the 3D printing technology Xueliang Ma Mechanical Engineering Department, Shandong Jiaotong University, jinan, P.
Laser rapid prototyping technology to create a model or prototype can be directly used for new product design validation, verification, engineering analysis, market order a business decision, shorten new product development cycle, reduce development costs, improve the competitiveness of enterprises.
Conclusion: 3D print areas of rapid development, from giant home printer to nanometer cell printer miniature, emerge in an endless stream of new technologies, but it is mainly concentrated in the professional field, the civil market or to the simple architecture of the FDM, whether the effect and accuracy of all strong enough, we look forward to working with the development of technology and cost reduction, desktop the 3D printer can truly achieve printing effect, then print 3D change the world will no longer be a dream.

Mechanical Properties of the Ecological Filling Blocks of the New Composite Wall Based on the Unified Strength Theory Wei Huang 1,a, Ting Zhang1,b 1 School of Civil engineering, Xi'an University of Architecture and Technology, Xi'an 710055 Chian; a qqhuangwei2005@126.com; b739483297@qq.com; Key words: ecological filling blocks; uniaxial compressive mechanical properties; the stress-strain curve; unified strength theory; yield criterion Abstract: In order to make the new composite wall structure the group developed to adapt different regional natural conditions, and along with the demand of gradually in-depth study the damage characteristics of the new composite wall, need to research the mechanical properties of the wall filling materials.
The yield criterion of the ecological filling blocks based on the unified strength theory [7,8] For all sorts of the engineering materials, the strength theory calculation criteria can be used as yield conditions，yield conditions or yield criterion can be used to determine the size and condition of begin plastic deformation stress of the material, it can be expressed as a functions of the stress state and material parameters
