First, we need to say that different lasers have different power, pulse energy, wavelength and laser beam quality. This means that each laser can do a different job. For example, some use metal and some use glass and acrylic.
1. Photo engraving on black glass
You can use all types of lasers including diode, Co2, DPSS and fiber lasers for photo engraving on stained glass.
Laser removes black paint and makes glass transparent.
2. Laser engraved beer mugs. Laser etching on glass.
The point is that glass is transparent over a wide range of wavelengths. If the glass is pre-painted, it can be engraved or etched using a Co2 laser or other methods. The laser beam passes through the glass, returns after hitting the back and marks the glass.
3. Acrylic badge
Acrylic is very similar to glass. It is also transparent to various wavelengths. That's why you need to make it opaque (either by painting it or applying some kind of tape) to be able to engrave on it. Or just use a Co2 laser for the task.
4. Acrylic DIY Chess
It's so cool to make something that can be used almost every day. I made an acrylic chess set for my son.
5. Stamps and Stamps
With Co2 or diode laser + 3D printer you can make stamps and stamps.
You can carve a stamp or stamp from a piece of rubber. Using a 3D printer, you can print out stamps or stamp holders.
6. Mirror Engraving
Another impressive thing that can be done with a laser is mirror cutting and engraving.
It is important to remember that you will need to paint and engrave the image on the back of the mirror to avoid double reflections when painting the image on a reflective surface.
7. Musical Instrument Engraving
We engraved the sheet music on the violin fretboard. I believe this will be very helpful for young violin students.
8. Laser engraving knife
Another friend of ours carved his knife. I should say that knife laser engraving is very popular among hobbyists and knifemakers. Mark the knives with a name or a special inscription.
9. Leather Wallet Engraving
I made a wallet for myself. The beautiful Bitcoin symbol is well engraved on genuine and synthetic leather. Remember that you need to be very careful not to burn your leather goods with the power of the laser.
10. Impressive Stainless Steel Photo Engraving
I was surprised to find that a 20 watt diode laser was able to engrave on stainless steel and make grayscale engravings similar to real photos.
