It was so amazing that I could make new products by printers. In my recognition, printers can only print articles, paints, and 2D products, but I never thought that a printer can really print 3D products. Before the actual training, I knew a little about 3D techniques, but I still feel shock about it when I did the actual training. I think human can be more creative by the using of the new technology. This kind of training really help me a lot in understanding of the new technology, and I would like to attend more training events like this.
