1. 3DpBurner.

[ID:610934] 3DpBurner is an open-source laser cutter/engraver.

It is created using the same RepRap concept, utilizing 3D printed parts and some easily found ‘vitamins’ (not printed hardware).

I tried to do this as cheaply as possible by using inexpensive electronics and ‘low-power’ lasers (laser diodes).

The X/Y workspace is fully customizable, with a maximum working object height of 50-60mm.

Note: You must provide proper protection for your eyes and prevent toxic fumes released by most materials. The first thing you need to buy before powering the laser is a pair of glasses suitable for your laser wavelength. The laser dot or reflections can easily harm your eyes. Avoid using invisible diodes like IR laser diodes, which are more dangerous because they are invisible when powered on.

2. DIY Desktop Laser Cutter and Engraver – FABOOL Laser Mini

[ID:1780556] FABOOL Laser Mini is an open-source, ready-to-use desktop laser cutter and engraver developed by Japanese engineer smartDIYs. The machine features excellent usability and scalability to meet various needs.

It all started a year and a half ago with a high-power 60W large laser cutter and engraver we developed for ourselves, which we turned into a small version of a desktop laser cutter and engraver, known as Smart Laser Mini. This time we released an upgraded version, FABOOL Laser Mini, with improved usability, stylish design, and a quarter of the assembly time.

3. 3D Printing Laser Engraver

[ID:819755] I would like to see some photos of your builds… have fun.

4. DIY Laser Cutter and Engraver

[ID:1026345] This is our first product, the ‘Smart Laser Mini.’

Smart Laser Mini is an open-source, easy-to-assemble laser cutter and engraver.

It is completely DIY, allowing you to engrave marks on various surfaces and even cut multiple materials with this laser.

Smart Laser Mini uses a simple mechanism that makes it easy to assemble. Additionally, this laser cutter is compact, making it perfect for home use.

5. Major Update for Laser Engraver

[ID:4817697] Initially, I did not plan to update this laser as it was also suitable for me in that version, but back in September Banggood started sending me different devices to satisfy my hobby after negotiations. We agreed on this collaboration, and I chose what I needed and what I thought would be useful for me, so this might interest you. So I got a 5.5W Neje laser head.

And don’t pay attention to the content displayed on the label 20W – this can be said to be the consumed power, but we are interested in optics and marketing, you know… so I guided my choice by optics, although I was modest, it could have been more powerful, but then the dot would be larger. I need the best option for a small machine as I already have a large machine, yes! The dot there is larger and the power is almost three times… the laser head Neje.

But just for the update – so for the update… I decided… to buy another controller and a standalone controller to avoid using a computer for engraving because lasers create a lot of smoke, it’s best to take it away while working…

The main controller is selected from Makerbase DLC v.2, running on GRBL, along with a 3.5-inch touchscreen from the same manufacturer.

About the screen, I want to add a few points: firstly, it comes with firmware for 3D printers, the laser needs to be re-flashed. The firmware itself can be downloaded from GitHub, and the machine can be configured from my archive. In the description, the manufacturer details how to change the buttons and the startup screen image… it’s enough to copy the firmware file to the SD card and restart the display, the update will start automatically. But! There is a subtlety: do not write files to the card from Mac, only write files from Windows, otherwise the image will become incorrect and look torn. The image itself is converted into binary code through a special program, this process is also described in the display instructions. Maybe this was useful for me, but it took me a long time to achieve results. Secondly, it can also be used with other controllers…

I installed TMC 2208 drivers, using them, the movements are silent.

In terms of mechanics, there’s a change that seems trivial but is very important. The bearings I initially used were roller bearings for tensioning the X belt, and they were a bit squeaky. I replaced them with MR63ZZ, paired them up, and now the mechanism has become quiet and smooth.

You can watch the video for more details on the updates, assembly, and engraving process. Still, just comments on cutting plywood work. For this process, strong blowing is required, I will show later, without it you cannot reach the inner cut and cutting will be impossible, it will only heat the coal, you can also get large areas of glue inside the plywood layers, in which case, every pass of light will melt the glue, and the glue will re-aggregate. Generally speaking, blowing is necessary, next time I will show. I also tried cutting 8mm thick solid wood, the result was almost cut through, but it was difficult without blowing. As I said in the video,

6. DIY Wifi Laser Cutter and Engraver with 3D Printed Parts

[ID:1233664] A variant of the smartDIYs DIY laser cutter using 3D printed parts.

The assembly is similar to http://en.smartdiys.com/smart-laser-mini/, but the cutting area is larger 330*330 mm.

I used black open-frame 500mm extrusion for the y-axis and x-axis, assembling the frame using two additional 430mm beams.

I created simple 80mm feet and a laser holder to accommodate the 70mm beam mounted on the x-axis. Additionally, you will find that the stepper, idler, and print plate each need to be printed 3 times.

The electronics use an Arduino Uno clone with GRBL shield V3.0 and 3 A4988 drivers. The distribution and keyboard/LED board are completed using Adafruit perma-proto PCB and UBEC.

The Arduino runs GRBL V0.9g firmware using the mr-beam fork.

The arduino connects to a Raspberry Pi running Octopi, which is modified for the Beam Mr. laser cutter to allow operation via wifi.

For more information on how to download this great software, please see the Beam Mr. page.

The laser diode is driven by a TTL driver M140 2W 445nm.

All wires are protected by a printed cable chain (item 34661).

The stopper is fixed by drilling holes on the stepper and idler plate.

7. ZDV Laser Engraver

[ID:2703455] This design helps you build a laser engraver.

All plastic details are very simple for 3D printing. The laser module holder is being tuned. Tight fit – no mechanical post-processing needed!!!

8. 15W Laser Engraver

[ID:3371373] This is a laser engraver/cutter.

When I designed this laser, I considered the functionality of each part,

There are endstop mounting brackets at the corners and both sides of the X axis.

There are belt tension knobs at the four corners for easy operation.

The laser holder has an adjustable knob to manually raise or lower the laser for focusing purposes.

All parts are printed at 65% scale, filled with 2 perimeter lines just to make the parts sturdier.

You will find a parts list with quantities and purchase links in the attachments.

Dimensions 1 meter x 75 cm

Building area 87cm x 58cm

9. Laser Engraver

[ID:4510600] After making a large machine last year, I wanted to make a small machine.

All the parts were bought a long time ago, but there will be slight changes in the future. I want to install a more powerful laser head. For this, only two parts of the bracket will change along the X-axis. The purchased laser will be delivered – I will supplement.

10. ZDV Laser Engraver V2

[ID:3347604] This is a 2500mW laser engraver (version 2). In this version, there is a cable channel and box for the electronic board (also a WiFi bridge). I tried to make a very cheap machine, especially for home labs. I hope it succeeds…

I combined GRBL v1.1f with Arduino UNO + CNC Shield v3.0. The laser module is 2500mW with TTL control line. To create GCODE and engrave, I used LaserWEB software. LaserWEB can perform shading (instead of pixel) engraving!

11. Project: Laserscythe – Another Open-Source Laser Engraver Using Recycled Doohickeys

[ID:1396503] This project is basically a laser engraver frame designed to handle leftover TAZ 3D printer parts and anything around me. It should easily adapt to any size or bearing setup you want to use. The electronic setup is a clone of villamany’s 3DPburner project (http://3Dpburner.blogspot.com/ ID:610934), the only real difference is the 3D printed frame and parts. I wanted to go a different direction with most of the work, and I wanted to ensure that they were all genuinely available in open-source form, so I ended up making my own parts.

This is the first laser I manufactured or designed, so it may require some adjustments. So far it seems to work fine!

Important note:

IV class lasers are dangerous if mishandled. Never use a laser without proper safety equipment, training, and interlocks. Downloading these files indicates your agreement to use them only in a safe, enclosed environment and to take all safety precautions. You further agree that you are qualified to manufacture and operate lasers and will not attempt amateur Lasik surgery.

12. CoreXY Laser Engraver

[ID:2805217] Check out my updates/remix, added a Z-axis and further improved the engraver! ID:3123030

Not long ago, I made a small DVD laser engraver, but it didn’t really work. Now, this new idea has become a reality by chance. When I upgraded the 3D printer Prusa i3 MK2 to the newer MK2S version, I had some spare parts, namely linear rods and bearings. Additionally, a 1W blue laser from eBay was sitting unused… and this is the result. 😉

With spare Prusa linear rods (370mm and 330mm), the usable work area of this engraver is 210x220mm. You could even add a few more millimeters.

The CoreXY system is loosely inspired by other systems, especially the excellent 3D printers Tech2C and Hypercube Evolution ID:1752766 provided by SCOTT_3D. Some other details also mimic these printers, such as the belt wrench system on the X carriage.

While these two systems guide the belts inside the printer, I decided to move the belts outside for maximum usable area. I didn’t use proper pulleys or idlers but used 625 ZZ ball bearings to transfer the belts. Currently, this is working fine.

The limit switches on the X slider were originally supposed to be triggered by the Y slider itself. However, when the switch finally arrived, they were different from my 3D model, so additional switch activators were added… it’s not elegant, but it works effectively. 😉

13. Core XY Laser – 2040 Frame

[ID:3154134] When I converted my (unbuilt) D-Bot to Hypercube, I had some spare 2040 extrusion pieces left, seeing that I had a laser diode waiting to be installed into my HyperCube or Tevo, I decided I could also use the spare parts I had lying around to build a frame and get it started and running as its own system instead of bolting it onto a 3D printer.

The frame is overkill for a laser engraver, but it makes sense to use them since I already had all the parts.

I used an Arduino Uno running GRBL v1.1f and CNC Shield v3.51 (anything above v3 should work for Core-XY, versions 3 and below do not support GRBL 0.9+, so there’s no functionality for CORE XY) or completely different boards.

14. Laser CNC

[ID:2765848] On this occasion, I created a laser CNC very similar to the commercially sold laser CNC.

Its parts can be 3D printed, and we will also add some parts I took from the same page.

In our parts here, they have different thicknesses, I printed them at 3mm, but they might be too soft, but it works well. I put other thicknesses so that you can taste it.

15. LED Laser Engraver

[ID:2916159] Homemade laser burner.

Laser 2.5W

Axle and linear bearings 8mm (on hand). I think that’s enough – it’s not a milling machine.

The frame is made of 25 profiles.

Motor Nema 17 34

The focus can be adjusted by raising or lowering the laser itself through the lens or through screws. Z-axis type.

Limit switches on all axes min/max.

With additional limit switches on the Mana SE controller.

Adjustable legs.

The machine is not large. I’m only interested in the building process.

Self-drawn printed. Of course, I found the idea somewhere.

16. Laser CNC ARDUINO 3D Parts

[ID:2801180] Preparing to include the Arduino part in the third part. Please follow me.

ARDUINO CNC LASER ENGRAVER PART 3: Calibration and Testing

As the IZLE ve YAP team, we previously released the electronic and mechanical parts of the CNC laser. Now it’s time for calibration and testing. In this video, we try to show you how to calibrate the CNC laser we brought to you.

First, we performed the calibration settings. Then we used the LaserGRBL program to draw 2 example images.

We used the character ‘LA CASA DE PAPEL’ as the example image.

Let’s go

If you want to make this ‘ARDUINO CNC LASER ENGRAVER’, you need some files. You can find all the files for download at the link below.

17. 3DPILE – $40 DIY Laser Engraver

[ID:868744] Here, you can find printed parts and instructions for building a fully functional laser engraver using two DVD drives and some other electronic components, costing only $20-50.

You might ask yourself: why is this project so cool? Only one answer. It’s the price point that makes it special. If you already have some parts at home and carefully procure these parts, you can build this amazing laser engraver for as little as $20. To have an accurate 3D print and accurate laser engraver for just $20-50 is just amazing, isn’t it?

I designed this project using SolidWorks. I tried to make everything as simple as possible (with almost no nuts, screws will thread) and I focused on the printability of all parts (all parts can be printed on a standard Makerbot Replicator). I wanted to keep costs as low as possible.

It basically works like a 3D printer, except it carries a laser diode instead of an extruder. You use Inkscape with a plugin to generate the files used by the printer. Then you just send it to the engraver, and it will start the engraving process.

18. Laser Cutter/Engraver with Laser Cutting and 3D Printed Parts

[ID:5180333] The laser cutter/engraver is made of plywood and 3D printed components.

Plexi can be used to increase the construction strength.

The structure is designed to prevent plywood deformation from affecting its stability.

19. Two Trees Totem S Laser Engraver: Modification

[ID:4807559]

This wonderful machine was provided to me by the famous Banggood online store, for which I am sincerely grateful. Although I already have several laser engravers that many of you have seen, this one must work anyway. Soon it must work hard. But first, I want to share some modifications with you, but not only that…

The story of its delivery is 3.14zdec… Customs wanted to warm the package, but this publication is not about the sad story of customs. In short: everything went smoothly 🙂 but! .. After starting the assembly and almost completing it, I realized that there were some things that I actually, as always, did not like about the standard version… well, that’s me 🙂 so I decided to modify it a bit. I don’t like the way the cables are organized and I don’t really like… After some thought, I came up with some small things, thanks to which now everything has grown together.

Once assembled, everything is simple, except for one small thing. The correct motor cables must pass through the profile. There is only one hole on the profile for this purpose. I used a signal wire with a cross-section of 23AWG, which is enough for the current characteristics.

I also added a display controller for autonomous control of the International Space Station, while the GRBL controller retained the standard controller.

20. iDR Laser Engraver

[ID:3470309] I designed this to utilize my discarded things. The inspiration for this design comes from the ZDV laser engraver, ID:2703455.

Thanks to ZhilDV for the design.

For small laser engravers below 100 square centimeters, you can use 2020 aluminum profiles, although using 3030 V-slot aluminum profiles will yield a sturdier structure.

The board from Creality Ender 3 3D printer will serve as the controller, which is based on Marlin firmware instead of GRBL. It will then have a nice LCD display and microSD printing functionality.

21. Cantilever Laser Engraver

[ID:4645406] This is a small cantilever laser engraver design based on ID:4605853.

I used most of the core design but adjusted its size for 2020 aluminum profiles and thinned most parts since they don’t need the same strength for such a small device. Using Zyltech’s 300mm extrusion, the work area is about 8″x8″. It could potentially reach lengths of 500mm, but I haven’t tested that yet. A little longer, and you might need a wider Y-axis stretch.

If you are looking for the best price for steppers and controllers, you can build it for $100-150.

I used a 7w Neje laser head from AliExpress, along with extrusions, steppers, and Zyltech’s Arduino control board, and it works great.

I included the .STEP files and Fusion Export files so you can edit and modify them as needed.

The gantry requires standard V wheels (7), 6mm spacers (10), 6mm eccentric adjusters (3), and M5 bolts (4 35mm, 3 30mm).

These parts are connected to the extrusions using standard M5 T-nuts (quantity 12).

The belt tensioner is connected to the legs using 2 M3 screws, but the legs themselves require brass threaded inserts. If you want to screw directly into plastic, just shrink the hole.

22. Engraver Master (ME10)

[ID:4126941] This is my third laser cutter/engraver, which I call ‘ME10’, representing ‘Master Engraver,’ and ’10’ representing the laser power (10W).

23. Laser Engraver

[ID:3589977] Watch my laser engraving operation!!!

24. Amazing DIY Laser Engraver

[ID:2870352] I designed this because I thought it would be fun around, who doesn’t want a laser!? It is built from old Monoprice Maker Select parts, which is a limitation on size. But it means it’s fully expandable. If you want to make it 4′ x 4′, then it should be entirely reasonable if you change the bearing sizes and adjust the holes (though using unsupported rods would lack strength, but you get my point). The laser engraver is rated at 2.5 watts, making it great for use as an engraver. With enough passes, it can cut through balsa, it just takes a lot of passes as it took me about 25 passes to get through 6mm balsa. So let’s get started!

25. CoreXY Laser Engraver Mk2

[ID:3123030] I’ve been upgrading the original engraver. When Jogi released his original version of Make (https://www.thingiverse.com/make:523254), he improved many shortcomings (more concise construction, larger area, chain belt), and we started discussing the implementation of the Z-axis. It took a long time, but now it’s the Mark 2 engraver with a powered Z-axis, effective stroke of 50mm.

For instance, the Z-axis can be used to find the best laser focus by scanning a specific height range. You can also adjust the focus on the sacrificial layer of the workpiece and then use the Z-axis to correct its height.

Of course, you can also engrave 3D surfaces. Although this might require proper CAM software.

26. Tlaser CoreXY Cantilever Laser Engraver

[ID:3783289] Tlaser is a laser engraver designed to demonstrate the new motion system coreXY cantilever concept. It is called Tlaser because this motion system and the shape of this machine resemble a T.

27. EleksMaker EleksLaser A3 Pro Laser Engraver Upgrade

[ID:3696310] I have an old EleksLaser A3 Pro laser engraver and wanted to share all the upgrades I made. I have not verified whether these upgrades apply to the latest version of A3 Pro, but they should be based on the images.

I included .stl, .step, and Fusion 360 file formats in my design.

For more information on the parts you need to print and the hardware you need to purchase, please see the ‘Upgrade Instructions.pdf.’

28. DIY Laser Engraver

[ID:3385854] DIY laser engraver using Eleksmaker Mana SE and 5500mW laser.

29. OpenBuilds Lead

[ID:4239719] This model was made in Sketchup, showcasing the modularity of the OpenBuilds V-slot system.

The LEAD machine stands out due to the modularity of the V-slot system, allowing anyone to modify it to make it longer/taller or add attachments to include diode lasers, plasma extruders, etc.
