The application of laser has been applied in many technologies. One of them is Laser based manufacturing. This technology is combined laser and photopolymer phenomena. Photopolymer is the phenomenon that polymerization of material by energy photon. Photopolymer material such as resin is liquid. If this liquid is shot by photon energy with certain wavelength, the phase will be solid because of the polymerization. Laser is narrow beam of light with very high energy. By controlling the beam of laser to the photopolymer material, an object can created.
The selection of laser type and photopolymer material is very important. Laser can be classified by its power and wavelength. Resin also can be selected based on properties. They have to be matched each other. If they are not match, failure will occurs. For example, the power of laser is too high, it will burn the resin. If wavelength of laser is not matched with resin’s properties, photopolymer phenomenon does not occur.
Controlling laser beam can be done by XY Scanner. This equipment can be programmed to drive laser beam. Inside XY scanner, there are mirror which has function to reflect the laser beam. By driving mirror movement, laser beam can be controlled.
This technology can be applied with another technology such as 3D camera. By taking 3D picture then process the data from picture to coordinates, it can be an input for XY scanner, thus laser beam can create the object which has the same with object taken by 3D camera. This kind of concept may be applied for construction of the skull of human. Before doctor do a surgery, this replica of skull can be used for practice.
