DIY Metal Engraving 6watts Laser CNC




Introduction: DIY Metal Engraving 6watts Laser CNC

About: my life through projects

here is a laser cnc i made which can engrave materials like Stainless steel, Painted metal, wood and etc. this laser has the power to cut wood also. the laser module is PLH3D-6W-XF professional engraving laser head from a company called Opt Lasers.

to show power of the laser module, i will make few projects with this laser cnc. so stay tuned.

Step 1: 6 Watt Laser Module (the Weapon of the Cnc)


Second generation PLH3D 6W professional engraving laser head offers high power and excellent ease of use. Improvements to the electronics allow the laser head to be powered by 12 - 24V, enabling compatibility with power supplies of nearly all CNC machines and 3D printers.

here is the link to the PLH3D-6W-XF laser head

Step 2: Designing and Figuring Out the Layouts

started with some hand drawing of how the cnc should look like.

Step 3: 3d Printed Some Parts

after make some rough stretches, it was then designed i fusion 360.

here is the link to the 3d printed part file

(this was designed and printed by my friend ) go visit him, he my cool stuffs.

Step 4: The Whole Base of the Laser Cnc

the base consist of the mdf wood and aluminum work area.

Step 5: Pcb and Wiring of the Cnc

pcb perfboard was used for easy development of the board

Step 6: Fluorescent Orange Acrylic Sheet

for protection

Step 7: Enclosure for the Cnc

made an enclosure for the cnc with aluminium cladding material.

Step 8: Here Is the Full Build Video

This would be my 6th cnc machine to build.The cnc machine was build with recycled part like stepper motors and linear rods from old printers.

Took around 30 days to build it, as most of the days went is hunting for parts.

Any doubt about the building process comment down below.

Step 9: The Final Look

Step 10: Watch the Part 2 of This Cnc to See What It Realy Can Do !

Here is the part 2 video of the laser cnc i made a few weeks ago, this video show some of the many things that can be done with this laser cnc. The laser module is PLH3D-6W-XF which is a professional engraving laser head from a company called Opt Lasers, which can engrave materials like Stainless steel, Painted metal, wood and etc. This laser module has the power to cut acrylic also.
