Introduction
A low-cost laser cutter ($1-2k) can be made using laser engraver parts.
- The CO2 laser tube - $500 for 80 Watts
- Laser tube mount
- power supply
- focus lens - $65 at [1]
- lens mount
- reflection mirror
- mirror mount
Design Rationale
The enabling point of a practical, low-cost laser design is the ability to do significant cuts (1/8") by performing multiple passes over the cut pattern. If each cut does 10 thousandth of an inch in steel for an 80 watt laser - then 12 passes give you a 1/8" cut. This is sufficient, for example, to laser-cut a 20" Sawmill blade
