Introduction: 3D Printed Laser Engraver

Picture of 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 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:


- 2x 440mm

- 2x 320mm

X axis

- 370mm

Step 1: Get the Parts

Picture of Get the Parts

What you will need:

1. 3D printer ;-)

2. PLA (any other material will work i think)

3. Aluminium profiles (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 but i think you can also print them.

4.2 Inner Squares

To connect the frame parts i bought them here 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

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


12. Coupler


13. Wiring

14. Fan


What else will you need?!

- screw driver

- double sided tape

- a drill makes it much easier sometimes

- cable fixers at the moving parts

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

Picture of 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'.

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

Step 5: Videos

I hope you like it! In that case please vote for it in the contest!

Step 6: SAFETY

Always wear goggles in an adequate wavelength!

Whats the software you guys use with this CNC?

leossoares made it! (author)slanwar2017-12-10

I use a repetier 0.92 with laser mode

Arduino mega2560, RAMPS 1.4, DRV8825, laser 2,5w and step motors 0,9º.

SethW37 (author)leossoares2017-12-08

what .hex file did you use for your firmware? i have a machine, but i can't find a .hex file that makes the laser and motors work, it's either one or the other

RD7 (author)2016-11-07

How much torque does nema 17 stepper motor need?

leossoares (author)RD72017-09-28

only two

leossoares made it! (author)2017-06-28

I Made with arduino Mega 2560, firmware repetier laser 0.92, step motor 0.9, Blue laser 2,5W and DRV 8825.

Chrome98 (author)2016-04-04

can anyone tell me how you accomplished the belt clamp? I have 2 types of slot nuts and neither will even fit in the slot with the belt under. I also tried just a nut - same thing. How did you do it?

Ask the company where you buy the profiles where you can get the right slotnuts...

Chrome98 made it! (author)2016-04-04

after having to figure out a few things it's together. as soon as I figure out how to clamp the belts down, I'm ready to give it a go!

Chrome98 (author)2016-04-03

I believe your spec for the bearing mounts screws is incorrect. they should be 30mm not 20mm. Could you please correct your requirements so that the next person to build that doesn't have a variety of screws on hand won't have to make a trip to return and purchase the correct screws. Thank you.

dapiguy (author)2015-05-13

I seriously need someone to provide a link for the aluminum profiles for purchase in Canada or the US. I can't find a place that's as cheap as yours, and I really want to make this!

Check out the Extrusion from REV Robotics. It is designed for linear motion like what is described in the instructable, and doesn't require special nuts for the slots.

It is available here

perhh (author)dapiguy2015-05-14

Try this one

They are located in IN US.

tobias.sobkowiak (author)dapiguy2015-05-14

sorry bud, but this isn't my market. I can't help you.

Chrome98 (author)2016-03-16

Could you please provide a printed parts list with quantities needed of each piece? Thank you very much.

No i won´t. Look at the pictures. It isn´t hard to see.

stevedee78 (author)2015-05-13

Hi could I get the following files to STP, PRT or DXF?

Seite_ohne_motor.stl Seite_motor.stl X_Achse_Beides.stl

I wanted to mill the parts.

Hallo könnte ich die folgenden Dateien in STP, PRT oder DXF bekommen?

Seite_ohne_motor.stl Seite_motor.stl X_Achse_Beides.stl

Ich wollte die Teile fräsen lassen.

I'll have a look when I'm back from holiday.

PsYhLo (author)tobias.sobkowiak2016-02-15

Do you have the parts in DXF?

Did you already mill the parts?

СергейР3 (author)2015-06-29

I collected. I replaced plastic details with plywood.

dregalia (author)СергейР32016-02-14

Did you do the wood parts on a CNC? You wouldn't happen to have the files available, would you? Thanks!

Cool please more Pics.

Looks awesome!

I hope you didn´t need the Aspirin onn the table!

TimF30 (author)2015-11-28

I would like to build something like this but use an old ping pong table as the base. That way I can engrave images and designs on large items like doors and table/desk tops.

dapiguy (author)2015-05-12

Could you post links to the eBay products in English for American purchases? I'd really appreciate it.

maikon_ayres (author)2015-07-17

Hi!, how laser type you have use with holder?

dapiguy (author)2015-07-09

How did you tension the belt the same? I'm in the process of making it, but when I'm installing the two belts that run opposite each other (the pulleys are connected with the rod), one side moves faster than the other because the belts have different amounts of tension. Does anyone know how they tensioned them the same? Thanks!

dollarseed (author)2015-05-12

I see a problem, your X axis is running above where the table should be, so you are super limited on what you can print. That should be run under the 2040. For anyone needing to get linear rails and bearings, and possibly Nema 17 motors to run these, along with the bearings, hit me up. I have been doing a lot of CNC builds and have great resources for everything, including Arduino Uno's and Easy Stepper driver board resources. Sorry, this wasn't meant as an advertisement, but rather constructive criticism :(

dapiguy (author)dollarseed2015-05-13

If you have any idea where to buy the aluminum profiles in Canada or the US, let me know. I've looked everywhere and couldn't find a viable place to purchase them from. Thanks for any advice!

dollarseed (author)2015-05-12

Wow, sorry bud, but I just realized one more major mistake. You only have X and Y axis. A true 3D printer would give you a Z Axis as well, and as an engraver, you should make that an option as well. It is much easier to raise the laser head off the project, than it is to lower the current to make a 3D shallow cut. I am only being critical on this, because I build custom CNC machines, and study everything in detail.

wgb7718 (author)2015-05-12

I really like how you put the belt into the channels in the beams. Cool trick!

PicengraverToo (author)2015-05-12

Cool, next you could set it up to laser engrave photos.

nonobadog (author)2015-05-12

Cool. If you used a cutting laser you could use the 3D printer to make the cutting laser to make a bigger, better 3D printer to make a bigger, better cutting laser to make a bigger, better 3D printer to make a bigger, better cutting laser, ad nauseum. Pretty soon you could rule the world.

....or make a "4D printed Threedeeprinter"

dhall-1 (author)2015-05-12

So you made instructions on a laser engraver but don't have your own laser engraver working? Page 4 said you were going to get your laser working then publish it, so did you get the laser or just publish it without testing your own device?

Is this an etch-a-sketch laser engraver? How do I load in a picture for it to engrave? What runs the electronics? Is this Pi controlled? I didn't see Pi listed on the parts or how to interface it with the engraver.

Or is this how to 3-D print parts to save money when making other peoples engravers?

tobias.sobkowiak (author)dhall-12015-05-12

I have already a laser (but not installed yet) and as you can see on the first picture the board is stick together. In the BOM you can see "additional laser, arduino clone....etc."

So no, not Pi controlled. But possible, if YOU´re able to.

I got all my knowledge from

There you can see how to get pictures on it. On my Arduino nano there is grbl 0.9 running and i get the pictures on it with grbl controller.

"Is this an etch-a-sketch laser engraver?" --> Kinda. As long as i don´t have the laser installed, i can use it with a pen or something, yes!

"Or is this how to 3-D print parts to save money when making other peoples engravers??" --> NO. It´s just for tinkering. Nearly every "engraver" is only an XY table. If you have a CNC or something it would be cheaper to cut them out of acryl.

Thanks for your helping on comment.

tobias.sobkowiak (author)2015-05-12

Thanks for your comment. You´re absolutely right...!

pacifcace (author)2015-05-12

If you make this with a laser powerful enough to do anything at all, even singe paper, keep in mind that you WILL need eye protection. This design has no reflection protection for the laser at all, and even a momentary glance of a stray reflected laser at the power levels you'd be using can be absolutely disastrous for your eyes.

Before you even think about building this, make sure you find the correct filtering glasses for the wavelength of laser you're using and ALWAYS wear them any time the laser is active.

If you can't find them, or don't understand what they are, you probably shouldn't build this or any other laser engraver/cutter.

BlueBlood Studios (author)2015-05-12

so basically, you are printing a 2D printer with a 3D printer. Now that's what I call printerception

ianmcmill (author)2015-05-10

I really like this one !

Nice and sturdy. Makes you wanting you use it :)


If you like it vote for it!

RtyQ (author)2015-05-10

awesome, might make one soon, what can it cut trough?

tobias.sobkowiak (author)RtyQ2015-05-10

Thanks! Don´t know yet, but it depends on the laser you use!
