Hi everybody, my name is Michiel and I am going to show you how to make an awesome looking laser engraver!
A couple of months ago, there was a CNC challenge here at instructables, while checking out the entries of that contest, I saw some pretty cool engraving machines and I thought: "Why shouldn't I make my own?". And so I did, but I didn't want to make someone else's project, I wanted to make my own. And so my story began... :)
This laser engraver uses a 1.8W 445nm laser module, of course, this is nothing compared to the industrial laser cutters who use lasers of (a lot) more than 50W. But this laser will do well for us. It can cut through paper and cardboard and it can engrave all kinds of wood. I haven't tested other materials yet, but I'm sure it can engrave many other materials. l will let you know! It has a large engraving surface of about 500x380mm.
Who can make this laser engraver? Everybody, if you are an engineer, a lawyer, a teacher or a student like me, you can build this thing! All you have to do is follow this instructable.
It took me about three months to design and build this engraving machine, including waiting for about a month for parts. I said three months, but, I'm only 16 years old, so I could only work in weekends.
++ As you may already know, this 'machine' uses a 1.8W laser with a wavelength of 445nm, the radiation of this laser is very dangerous for your eyes, even a reflection of it! So I strongly advise you to use safety goggles with the wavelength of the laser you use! ++
You can't make a laser engraver without the parts, so I made a BOM-list with almost everything you need to make it. Almost everything in the BOM is bought from Aliexpress.com because it's cheap and it has free shipping for most items. Other parts like the threated rods and the wooden sheets were purchased at my local DIY company. I ordered the laser and the laser driver on ebay.
UPDATE: I've uploaded the BOM in two formats: one .pdf and one .xlsx since not everybody could open the BOM.
I tried to find the cheapest products for all the parts (shipping not included).
