Abstract - Essay Exampleng to the authors, combining of new and inexpensive technological methods whitethorn increase the availability of more flexible ways for dealing with the common challenges in forensic science. They, therefore, intend to present a method of 3-D laser scan of chewed gum found at a crime scene into a digital file format. In a bid to justify the repulse of their research, they point out that the procedure they used in their research project does not include all form of contact and is nondestructive thus more efficient prior to extracting DNA from the gum. The theme of their research is that their method, which involves generating a digital file, could be used to for dental comparison in the future in case the authorized chewed gum gets damaged by forensic analysis following 3-D scanning.In their research, they used an automatise 3-D laser scanner that ensures a reliable, affordable, and reproducible means for scanning a 3-D endeavor fast and at a possible res olution of 127 microns. They scanned a piece if chewed gum that had air desiccated for 24 hours by placing it on the tip of a tuberculin syringe needle, and then positioning it on the scanning stage of the laser scanner that is fully robotic. Using precise scan parameters of the laser scanner for a 360 degree scan, they used macro 0.005 inches precision, 125 seconds scan speed, and 0.005 triangle size. This process took less than three legal proceeding given that they set the light in color of the target surface to that of the matte finish, and the smoothing had auto-align of the eight segments on with a setting of 1.After all the procedures involved in the process had produced digital files, they were able to baffle up with a virtual block that showed the shape and contours of the teeth impressions just like those in the legitimate gum. They then used a Web-based prototyping service called Shapeways to order for clear resin as well as white plastic models of the gum from their d igital files. All this took less than 10 minutes, and they
