About Tech Shop
I made this at TechShop San Jose.
I made this at TechShop San Jose (http://www.techshop.ws/). TechShop is a "build it yourself workshop" where members go to build their hopes and dreams. I joined TechShop San Jose to work on my business ideas and I have met a variety of passionate and hard-working characters. I implore you to check out their website if this sparks your curiosity!
Laser cutting has a variety of applications, some popular ones include etching wine glasses, etching awards, cutting signs, customizing personal objects (such as laptops), and fabric cutting. Those are just a few of the applications. The possibilities are limitless.
History of Laser Cutting
Laser cutting and etching is a technique used since 1965 and is very popular in the manufacturing world. There are three main lasers: CO2, neodymium (ND), and neodymium yttrium-aluminium garnet (Nd-YAG). A CO2 laser operates by emitting a gas mix (DC-exited method) or a radio frequency (RF-Exited method) to cut/etch the objects. Using radio frequency though a laser cutter is a new though increasingly popular method of cutting. CO2. Lasers use different techniques to cut/engrave objects. A laser microjet uses water to guide the laser beams. Different techniques produce different advantages to the mission you might be trying to complete.
The laser cutter I am using is called the Epilog CO2 laser cutter and has two different models of a 45 and a 60 Watt cutter. I am using a 60 watt cutter because that is the only one at the TechShop San Jose location at this time. The width of the tables at TechShop are 24"x18".
Harmful gasses and bright lights are both emitted from laser cutters. Although it is not required to wear eye protection or facial masks, a user could only benefit from wearing such protection. Facial masks are highly recommended when cutting any plastics. Remember safety first!
Depending on the speed and power the laser cutter is set at, small fires are potential problems too. If flames do appear during the cutting process, quickly turn off the printing process and proceed in the manor that best seems fit. A user should not leave the immediate proximity during the laser cut (unless another individual equally well knowledge in the machine looks after it while the user is away). If you must leave the work area, press the "Stop" button on the laser machine to pause the process to ensure safety while absent.
