These materials aim at furthest satisfying the demand of teachers and students and circulate fast.
The Common Development of Aesthetics Curriculum Resources by the Cooperation between Exhibition hall and University.Art Course Standard certified that we must make use of all of course resources off campus, including art gallery, library, public museum, private museum, local cultural relic materials, artist studio and art workshop.
Idle and wasting phenomenon of some imperative materials in art course is very remarkable including some originals donated from virtuosos such as Yin Shoushi, Qin Lingyun, Jiang Wenzhan, Chen Niuyun, Zhang Fuxing and Huang Gesheng, video recording, lantern slides, replica, folk embroidery, historical photos, native costume and sculpture.

Resulting parts show high detail resolution and no support structures are required, however mechanical strength is lower compared to conventional manufacturing methods and only few materials are currently qualified [6].
Direct energy deposition can be described as a process in which focused thermal energy is used to fuse materials by melting as they are being deposited.

Large grain sizes cause a disruption of the cutting edge material.
Hence, there will be less material in the top level of the surface and larger material ratios in lower levels.
Based on the profile data a material ratio graph can be calculated.
The material ratio of the grinding wheel includes the binding material with deeper penetration depths.
