Ⅰ. INTRODUCTION
In fourth semester most of our department students attend the subject of mechanical manufacturing practice and we have made a bolt by ourselves. But the process was not a soft job. A bolt and nut is used diversely but it seemed that we don't know much about a importance and manufacture of bolts.
A bolt is a threaded fastener used inindustry to make two or more mechanical

the defining characteristics of living organisms is their inherent ability to repair physical damage. A growing trend in biomimicry is the creation of non-living structural materials that also have the capacity to heal themselves when cut, torn or cracked. Self-healing materials which can repair damage without external human intervention could give manufactured goods longer lifetimes and reduce t
elements of kitsch and the grotesque in his comics, drawn in particular from sixties pop culture, MAD magazine, and the San Francisco underground comics scene of that era. From 1985 to 1989 he contributed both art and stories to Cracked magazine. On September 16, 2007, The New York Times Magazine published the first installment of Mister Wonderful,a serialized graphic novel written by Clowes.
3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.
