<p>The best option is to use <em>acrylic cover</em> in same color as your laser, so you can observe the etching process and the laser beam is always blocked.

<p>Another protection is to wear <em>laser protection glasses</em>. Again the glasses must have same color as your laser. </p>

<p>Using laser for cutting or engraving means to burn material away. You should have good ventilation in the room.</p>

<p>Buy a <em>smoke detector</em> if you use cheap electronics with higher power consumption.</p>

As an alternative to editing this, you can always delete it to earn the 'peer-pressure' badge. I think it's important to address the safety issues if you do answer this question. To clarify - not my downvotes (hadn't voted on the question till now)

<p>I have a printer and a diode laser head which will etch aluminum for under $4k, but you're going to have to manage potentially noxious fumes based on what material you're lasering. It's safe if used safely: the focal distance is 15-20mm from the lens, but all present should wear PPE.</p>

How cheap, what area, engraving what material?

There are ways to do one or several at home (I made one), try to look for laser forums.

This question is very opinion based, it's also asking for 'competent person' advice in terms of safety. If you want safe, pay someone who has insurance. Thinking a bit more about this question (and adding my downvote), I think it needs to be split into a few parts. Clearly a laser engraver _can_ be built from scrap, what is easier to answer in the context of this site is some details about 'is a CD player laser strong enough to engrave', what safety do I need with a CD laser (or other type if you go that way). The business aspect of using DIY hardware I think is way off topic.

"cheapest" is a pretty much impossible to answer question. One might arguably get it rather cheap if one converts a printer ot an engraver... This might best be a host for Laser-cutter questions interlinked or a general design consideration question. Basically there is a design triangle of "Cost-Safety-Versatility" to cover here: to go into one direction of this design triangle means to sacrifice in the other two, to to a compromise of two of these means to sacrifice in the third: there is no "Cheap-safe-AND-Versatile" machine.

# How to build a cheap (but safe) laser engraver with spare parts

(Asked by: username_0 on 2018-08-13)

I would love to start a small engraving business without having to purchase expensive hardware.

Using scrap parts at home, or parts from broken CD players, are there any ways to make a laser engraver at home? My cousin managed to make one of his own from scraps.
