In describing the answer to the question below, try to share your opinions on the basis of evidences such as articles and books. Also provide information of the evidence (author, title, journal name, etc.).
1. Explain what happens in terms of mechanical/chemical properties when making products using metal-based 3D additive manufacturing technology. (10 points)mechanical properties

Young's modulus: 0.5TPa (GP)
3. Introduction of a thesis
By incorporating nanoinclusions (carbon nanotubes, graphene sheets) with exceptional thermal conductivity into a polymer matrix, one would expect to improve the heat performance of resulting nanocomposites. However, the effective thermal conductivity of carbon-based nanocomposites is strongly

According to this, they reflect a taste of a customer, send a product news letter. Also, they provide the opportunity that customers receives giveaways and as to be able to participate in a speci
of other security incidents. Figure 1.2 indicates the conceptual structure of the security planning cycle. Reassessment of threat should take into account not just the level of threat, but also perceived trends, especially the type of weapons used and the techniques and tactics employed. Reassessment, if it is to be of any value in the preventative sense, should be based on accurate and timely in
