Overview
The printer that is widely used is 2D printer. 2D printer is operated with papers and ink. It can print the letters, shapes and colored pictures on the paper. However, 3D printer can make 3D structure with ink like polymer. 3D printers make the product with not the top-down method but the bottom-up method. The most useful advantage of 3D printer is that it is the more useful device wh

Recently, due to environmental pollution and climate change, attention to environment is more growing than ever. Especially, buildings form 40% of energy and resource consumption, 30-40% of carbon dioxide emission, 20-25% of waste discharge, 17% of water consumption, and 25% of wood consumption, so buildings are mainly responsible for
