This is a very fun project if you have a lot of time and love to build everything rather than just going to the store and buying it. This guide will show you how to build a CO2 laser cutter with a cutting bed size of 3. X1. 7X1. 0. It costs about 1. Video of the system cutting cardboard: http: //www. Jxx. NYt. II apologize in advance, this is my first instructable and I am not the best writer. First thing to know about building a laser cutter is that this is an extremely time consuming, dangerous, and difficult process. You should not work alone. If you hurt yourself, you need someone around to call for help. This is a very real concern. Things to know when working with lasers: * Death: Voltages as high as 5. This can instantly kill you.* Blindness: The laser used here can destroy your vision before your brain can recognize there is a problem.* Fire: The laser used here can set objects on fire without your knowledge through a reflection of the beam. Whenever the laser system is powered: * Eye protection should be worn by you and everyone else* Doors and windows should be closed* Insure adequate distance between you and high voltage terminals. The laser used here emits infrared light which is invisible to the human eye. Considering that this light cannot be seen, it is difficult to tell where the beam is being directed. Polycarbonate absorbs infrared light very well. I recommend you head over to home depot and purchase several pairs of clear polycarbonate safely glasses. Do not fire the laser irresponsibly. Now that we got through all the safety stuff, I have one disclaimer: I highly do not recommend that you do not build a laser cutter. Cheap Chinese laser cutters can be purchased on e. Bay for less than 1. I understand that most Chinese laser cutters do not function properly upon delivery, but with minor repairs they can be made to function as well as the laser I am about to describe, with far far less work and with a similar amount of financial investment. About CO2 lasers. The type of laser most common used in laser cutting is a CO2 laser. CO2 lasers work by exciting CO2 (along with other gasses) inside a tube at 1. When the gas is excited it creates infrared light which is reflected back and forth between a full reflective and partial reflective mirror. ![]() GUIA DO PRAZER: Tudo o que você precisa saber sobre sexo está aqui Torne-se um expert, aprenda com a experiência de outras pessoas. Catalogna. Catalogna, voto tra tensioni. File nonostante i divieti, la polizia.Catalogna, è battaglia nei seggi: la polizia carica, molti feriti. When enough infrared light exists to exceed the reflectivity of the partially reflective mirror, the infrared light exits the laser tube through the partial reflective mirror. The infrared light emitted from the tube is directed at other full reflective mirrors to get the light to the surface you would like to cut. Once the light is at the right location, the light needs to be focused to a point using a focusing optic. At the focal point of this object, is the object you would like to cut. Making a CO2 laser. At the beginning of this project, I was interested in making a laser tube from scratch, but I discovered the lasers that could be made at home would not be very reliable, while being expensive to operate. I managed to find a sealed 4. Bay. Some say this is cheating. .

Cut off a 1 inch segment on one side of the end of the angle iron. Make the same cut on the other end of the other angle iron. This will leave you with 1 face of the angle iron 4. These cuts will allow the belts to pass on the left and right. Mark the inside of the 5. Take the remainder of the 8 foot piece of angle iron and cut it down to 2 pieces of 2. Find the center of both of these pieces. With a permanent marker, mark an inside face of both of these pieces at 1. Take a linear bearing track assembly and remove the blocking cap on one side. Remove 1 linear bearing. There should now be 2 linear bearings on the linear bearing track. Replace the blocking cap. Repeat this for another linear bearing track assembly. Place a modified linear bearing track on a 2. Line the center mounting hole up with the 1. Insure the linear bearing can slide the whole length of the track with 1/1. The linear bearing assembly must be straight on the aluminum angle iron. Mark all mounting holes on linear bearing on to aluminum angle iron with a permanent marker. Remove linear bearing assembly and drill out mounting holes with properly sized drill bit using a power drill or drill press. Repeat for other 2. Take the two remaining linear bearing track assemblies and remove blocking caps from both. Remove all linear bearings from one of the tracks and remove 1 from the other track. There should now be 2 linear bearings on one of the tracks, and none on the other. Do not reinstall blocking cap. Place both linear bearing tracks on the inside of the long face of the 5.
