Table 1 : Summary of AM Techniques (Ngo et al., 2018) (Ho et al., 2015) (Gao et al., 2015)(Ren, 2 Shao, Lin, & Zheng, 2016)(Srinivas (Srinivas & Babu, 2017)(Olakanmi, 2017) Cochrane, & Dalgarno, 2015)(Derby, (Derby, 2015)(Bikas, 2015) Stavropoulos, & Chryssolouris, 2016)(Dehurtevent (Dehurtevent et al., 2017)(Ahn, 2017) Kweon, Choi, & Lee, 2012)(Fina, (Fina, Goyanes, Gaisford, & Basit, 2017)(Herzog, (Herzog, Seyda, Wycisk, & Emmelmann, 2016) LATEST TRENDS IN THE APPLICATION OF AM In Medicine Manufacturing, Several kinds of Drug Delivery Systems (DDS) have been established using 3D Printing with variations of drugs and active agents (Deng Guang Yu, Li-Min Zhu, Christopher J. Branford-White, 2008). SLS 3D Printing is used to produce oral medication loaded products without degradation using pharmaceutical grade excipients, i. e., medicine manufacturing, See Figure 3 (Fina et al., 2017). Solid Free Form orm (SFF) techniques are used to produce freeform geometries offer a unique alternative for producing DDS with complex in shape and microstructure (Jonathan & Karim, 2016).
