The desktop printer materials has low melting point, the platform when heated to 80℃-90 ℃, the material will soften, and removed easily.
At present, the lack of related standards, in domestic there has the ability to produce 3D printing materials companies rarely, quality is uneven, especially metal materials mainly rely on import with higher price.
Therefore, the current one of the urgent task is to build a 3D printing materials related standard, increase investment of 3D printing materials research and development and industrialization of technical and financial support, improve the quality of the materials used in domestic printing, so as to promote the development of printing industry in China.

Some materials the teacher and students select may not be suitable for the teaching goals. [5] The information downloaded from the internet is too much, so it is difficult for the teacher and students to select the appropriate materials for the writing course.
Hence, in the process of preparing for the writing materials and samples, the teacher should take efforts to take the essence and discard the dross.
In the writing instruction, computer technology can help teachers to prepare the writing materials, make the class more attractive and arouse the students’ enthusiasm.
