3D Printed Laser Engraver

Hi folks!

I built my own laser engraver and want to share it with you in this 'ible'! I made it with the help of my 3D printer.

I saw this one http://www.banggood.com/500mW-Desktop-DIY-Violet-L... and thought i could print the acrylic parts. This is why i made it.

My working area is:

X 265mm
Y 345mm

But it depends on the aluminium profile you´ll buy.

My parts are:

Frame

- 2x 440mm

- 2x 320mm

X axis

- 370mm

Step 1: Get the Parts

What you will need:

1. 3D printer ;-)

2. PLA (any other material will work i think) http://www.amazon.de/NuNus-Filament-MakerBot-Maker...

3. Aluminium profileshttp://www.ebay.de/itm/150956267616?_trksid=p20578... (i used the 6mm groove. You can also try 5 mm groove, then you maybe don´t need the roller .stls)

4. Slot nuts and inner squares

4.1 Slot nuts

You´ll need 6 slot nuts. I bought them here http://www.ebay.de/itm/161168970108?_trksid=p20578... but i think you can also print them.

4.2 Inner Squares

To connect the frame parts i bought them here http://www.ebay.de/itm/281585620876?_trksid=p20578... maybe you can also print them. 8 pcs.

5. Screwsand nuts (buy them at your hardware store)

12x M6x25 (To fit the feet and the side parts of the x axis you´ll need)

12x M5x20 to attach the bearings to the moving pats

3x M5x45 to connect x-axis moving parts

4 screws fot the slut nuts (i used M4)

2x M2 to fix end stop to y axis foot

Some M3 to fix the motors

6. Bearings

You´ll need 13 peaces http://www.aliexpress.com/item/chrome-steel-bearin...

7. Rod (length depends on your build)

1x http://www.ebay.de/itm/181470570665?_trksid=p20578...

What else will you need?!

- screw driver

- double sided tape

- a drill makes it much easier sometimes

- cable fixers at the moving parts http://www.ebay.de/itm/100-Stuck-Selbstklebe-Recht...

Step 2: .stl Files and DXF

I first printed some parts vertical, but the motor holes were some kind of comressed then. It is much better to print them horizontal...

Step 3: Assembly

I will post some editorials here later.

At all it is very much self-explaining, but here is it in short. If you have questions i´ll do my best to answer them.

1. assemble the parts with the bearings

2. screw the motors on the parts

3. put the x part on the axis

4. add the side parts of the x axis

5. assemble the frame

6. put the x axis on the frame

7. screw the feet

8. screw the laser parts on it

Step 4: Electronics

All the credits go to ianmcmill for his great support so far.

I got all my instructions from his 'ible'. https://www.instructables.com/id/Frankenstein-Laser...

I didn´t get the laser working yet, but will try to and then publish it.
