Cutting with lasers can be very dangerous and when accidents happen they tend to get quite nasty the Raspberry laser has taken a lot of things into account such as:
- Component price
- Time taken to complete project
- Light intensity (If it’s too light it could damage your eyes- don’t worry about your pets, human eyes are different)
- Diversity and modification
The laser can be changed to suit your needs and will cost $100 at most and is mostly used to cut paper. Great precautions should be taken to keeping the laser away from children as accidents may happen.
The laser is similar in design to a guillotine with the blade being replaced by the laser. Thus modifications should be made if you want to use this laser as a welding tool.
