In our first presentation we represented our idea of developing a system which can be used for laser based lithography, as Lasers are developing and future is based on laser, so keeping up with the ongoing trend. A system which can reduce the time span of wafers manufacturing. Along with that we provide a solidwork generated generic 3D design of a laser engraver. We also attached the gaand chart and the pricing for making a laser engraver/cutter from start. In our second presentation we discussed the conversion of a 3D printer to a Laser Engraver machine, which provides us with a multipurpose machine which can act as both an additive and subtractive machine, We provide the details of the laser which we have used to perform our operations, we also discussed about the in depth details of the softwares we have used and the problem we faced and how we dealt with them. It also shows us the results we obtained and a small video.

Suitable for engraving the material can be
burned by fire, such as wood, bamboo, paper,
plastics, leather, PU leather, PVC, rubber,
colorful ceramics, colorful aluminum,
cobblestone and etc..
Also can be used for cutting paper, leather, non-
woven cloth, flocked fabric, and etc. which is no
thick than 2mm.
