Introduction: 3D Printed Laser Engraver
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:
But it depends on the aluminium profile you´ll buy.
My parts are:
- 2x 440mm
- 2x 320mm
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
You´ll need 13 peaces http://www.aliexpress.com/item/chrome-steel-bearin...
7. Rod (length depends on your build)
8. Pulleys and belt (you need three pulleys or print them)
9. Maybe endstops
10. Laser heat sink
11. NEMA 17
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...
The dxf files are made by user stevedee78 all credits to him...
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.
