Product Description
The parts included in the Prusa Laser Upgrade with PLH3D-2W Laser Head are listed above, in the section “Individual Kit Parts”
Important Note: Please bear in mind that this Upgrade Kit contains Prusa 2 W Laser Head, which is a different product from our standard 2 W laser head.
Turn your Prusa 3D printer into a laser engraving and cutting platform!
Our Prusa Laser Upgrade Kit is a low-cost solution for both amateur enthusiasts and professional applications alike. It allows users to customize their 3D printer and expand its functionality. The blue PLH3D-2W Laser Head is light and suitable for engraving, marking or cutting a variety of materials, such as textiles, wood, cardboard or leather. The kit includes a customizable STL model of the laser mount, which can easily be printed on the Prusa 3D printer. The set-up process is both simple and straightforward. A manual for mounting the laser head and getting started, as well as software, is downloadable from our website.
PLH3D-2W Engraving Laser Head
PLH3D-2W is a medium power 2W professional engraving laser head. This lightweight 70-gram laser does not require any external cooling. The heat sinking design not only cools the laser head, but also protects the lens from dirt by creating an air nozzle. The PLH3D-2W is designed to work with common 12V power supplies with a minimum of 1.5A current.
The laser driver is equipped with an LED indicator that displays all the information essential for operating the laser. An integrated temperature control system is designed to turn off the laser head when the maximum operating temperature is exceeded. By attaching the miniature driver directly on the laser head, the speed of diode modulation is improved in comparison to systems with a separate driver. This design allows connecting longer cables to the head, if needed.
Analog modulation enables users to control the laser power. 0V is equal to laser output power 0W (but still armed), 5V equals to the maximum output power of the laser, 2V corresponds to around 40% of the maximum power. This can also work as a TTL input if a voltage of 0 to 5V is used.
In case users wish to modulate power through PWM, the acceptable base frequencies are in the range between 5 and 10 kHz. Thermal tests we conducted on several prototypes allowed us to optimize the radiator’s shape and enable efficient cooling, maintaining a compact size of the device. Overall the laser’s functionalities are standard for PLH3D Series, but the smaller spot size opens a possibility to illuminate surfaces covered with a photosensitive material. This gives a chance, for example, for a very quick PCB prototyping.
More information on the PLH3D-2W Laser Head can be found on the product’s website here.
Printable Height Reference Tool
Moreover, the kit includes an STL file of a height reference tool that can be used for calibration of working distance and the focus on the Z-axis
How to use the Height Reference Tool:
- Mount the laser head on your printer.
- Place the adjusting tool on the working plane of the printer, under the laser head.
- Using your controller/software move the laser head in Z-Axis, try to gently touch the reference tool. At this point you can calibrate Z-Axis.
Disclaimer
The included file for a 3D-printed mechanical mount is included for your convenience. It is intended to be printed on by the customer. The design can also be modified by the customer to suit their specific needs. Note, it is the responsibility of the customer to ensure that the mounting adapter is well-suited to allow the laser to be mounted and operated safely. Tomorrow’s System and its affiliates take no responsibility for the reliability or performance of the laser mounting adapter printed by the customer.
Caution
- Remember that it is not a toy.
- Laser radiation is dangerous even when scattered or reflected from any surface.
- Always use proper protection laser filter on your CNC machine dedicated to 430 - 480 nm in order to avoid reflected radiation.
- Never point laser head at people or animals.
- Do not touch the beam, it may cause burns or another injury.
- Do not stare at the beam or the beam spot while the material is being cut.
- Laser radiation - Avoid eye or skin exposure to direct or scattered radiation.

Great Laser for Prusa!
Overall great experience! I installed this laser on my Prusa MK3S+ using the printable adapter and connected the laser harness to the print fan. Very clear instructions and straightforward to install. I've been commanding my printer through USB to Pronterface so I have full control for safety purposes and starting/stopping laser jobs. The laser power is plentiful, so definitely use this in an enclosure with proper eye protection/laser shielding panels (and fume extraction). I mainly used it to engrave and cut through balsa, MDF, and with enough passes, 3mm plywood. The G-CODE generator software it comes with is decent, you do have to tinker with the settings to get the power/feed/speed settings right depending on what you are cutting. I've found myself creating SVGs and generating custom GCODE using Inkscape plug-ins and writing in lines as well. Both methods can yield good results with enough tinkering. Excellent value for the price and a handy tool for an already very capable printer!
