Draft

Low-cost Laser cutters typically used in Fablabs can cut and engrave. They can use materials materials such as wood, Plexiglas or cardboard and cut out various shapes and sizes from them.

Opensource kits / do it yourself

Reprap.org has an interesting Laser Cutter Notes article plus and associated Background page. Both together include instructions on how to create your own, general information plus links to projects.

Lasersaur

Quote: “The Lasersaur is an open source laser cutter. We designed it to fill the need of makers, artist and scientist who wanted a safe and highly-capable machine. Unlike others it comes fully loaded with knowledge to run, maintain, and modify.” (Lasersaur, 6/2014).

axCut

  • axCut
  • Work in progress as of June 2014

LAOS

  • Laoslaser.org
  • Is not a laser cutter but a board + software. It can be be used to onvert existing machine with a better (open source) driving board or for DYI projects.

List of low power commercial laser cutters

This is a just a quick list made be someone who has no expertise.

When comparing prices consider the following (thanx to Wie ich mich für einen Laser entschieden habe.... by Matthias Melcher)

  • Laser tubes must be replaced once in a while (cheap ones cost 500 Euros, good ones 3000 Euros and more). Cheap ones last a few hundred hours, excellent ones (e.g. Synrad) over 20'000 hours (that's many years). In other words, price differences are partly explained by the quality of the laser. The same is true for other parts (mirros, filters, etc.)
  • Cutting/engraving most materials produce dangerous fumes, therefore you also must buy a system to manage the exhausts, i.e. either pump it outside or into a box with a filter. Some materials contain Chlorine (e.g. PVC) and that produces very corrosive fumes. You should not cut these, even with a good exhaust system since the acid will damage your machine.
  • Most activities need cooling (air or water)
  • The laser beam is invisible (but you can add some red dot)
  • Cutting depth is limited, you can't cut deeper even with several passages because the laser is "conical".
  • Lasers can burn (therefore don't leave it alone, and keep a fire extinguisher ready)
  • A laser machine needs space, e.g. count exhaust system, cooler, etc.
  • For many types of use you need extra materials, a cutting table with holes (honeycombed), a cooler (water pump), etc.
  • Laser quality is fairly different, laser power is a relative measure of engraving/cutting strength.
  • Cost / hour could be 20 Euros

In the hobby range, there are at least two types of lasers:

  • C02 / glass. Good for leather, paper, acrylic (plexi glass) and plywood,
  • yag and fiber (good for metal)

Quality / origin: It seems that there are huge price and quality differences in the area of low cost / low power desk top laser cutters. E.g. laser cutters directly imported from China may cost half of Chinese models assembled in Europe, and the latter cost half of high-end American Models. E.g. seemingly similar machines can cost 4 times as much (or more):

  • Direct imports for China: There are many models, e.g. BaiSheng, RedSail. Some of these can be adapted and certified by local companies.
  • Western made/adapted from cheaper parts: Arketype, MLLog, FullSpectrum. (Often?), these models also provide their own software.
  • Expensive parts, US or European made: Epilog, Trotec
