My first laser cutting

I made the first name tag in laser cutting.

Before going through the process of laser cutting. I want to introduce what is a laser cutting machine and what it does.

Laser cutting is a technology that uses a laser to slice materials.

The history is that In 1965, the first production laser cutting machine was used to drill holes in diamond dies. This machine was made by the Western Electric Engineering Research Center. In 1967, the British pioneered laser-assisted oxygen jet cutting for metals. In the early 1970s, this technology was put into production to cut titanium for aerospace applications. At the same time CO2 lasers were adapted to cut non-metals, such as textiles, because, at the time, CO2 lasers were not powerful enough to overcome the thermal conductivity of metals.

First, I design the shape I want in the Adobe Illustration.

The most important rule is to colour the lines differently.

Red is laser cut

Blue is laser engrave

Black is laser etch

When I made my name tag, I coloured the body was red, the name was blue and the image I wanted was black.

And then I need to set up the file in the laser cutting machine.

The way the machine was set up on this day is a bit complicated and I still can't remember it all. I thought I'd have another chance next time, but I'm sorry that I can't use the lab because of the lockdown. I want to go back to school and understand how to set it up again and use it in wood or other material instead of plastic plate next time.
