Buying Guide of UUNA TEK Pen Plotters

Buying Guide: Pick Up the Right Version of UUNA TEK® and Laser Heads

First part: How to Pick Up the Right Laser Heads?

Update on August 7th, 2023:

As the creasing demand of laser engraving heads, we updated the buying guide for those different laser power heads at the beginning for your reference.

Choosing the right laser power can not only improve the efficiency and quality of engraving but also ensure operational safety. When purchasing a laser engraving machine, it mainly depends on the material to be engraved, while considering your own needs and budget.

The laser module of a small engraving machine generally has a power range of 0-15W, mainly used for surface engraving and cutting of materials such as paper, thin plastic, thin wood, leather, and metal (with surface coatings). The following materials cannot be engraved: metals (regardless of thickness), stone, ceramics, gemstones, reflective materials, transparent glass, ivory, colorless transparent materials, some white plastics, etc. (generally very smooth plastics are difficult to engrave).

UUNA TEK® Pen Plotter offers the following laser modules: 0.5W, 1.6W, 2.5W, 15W. Materials that can generally be engraved include: light wood, kraft paper, fabric, leather, some plastics, wood, bamboo, opaque acrylic, etc. If for cutting purposes, it is recommended to use 2.5W and 15W lasers for faster speed and better quality, but ensure the safety of use.

For different materials, you can refer to the following table for specifics:

Second Part - How to Pick Up the Right Version of UUNA TEK® Machine?

Firstly, you can pick up the version based on the application

What kind of functions you may use it? Here are some suggestions:

For those who are looking for a handwriting machine to imitate your handwriting fonts, UUNA TEK® 2.0 A4 or UUNA TEK® 2.0 A3 will be the best choice for you. Many of my business customers, like, who is providing postcards writing service, vote for the UUNA TEK® 2.0 A3 version with basement.



For those who are looking for a simple drawing tool to realize your generative arts with different pens, or imitate some masterpieces downloaded from the internet, UUNA TEK® 1.0 A4 or UUNA TEK® 1.0 A3 will be the best choice for you. Our 1.0 version has better performance when drawing at high speed. 



Secondly, you can pick up the version based on the size you need.

Generally speaking, we provide both the A4 and A3 versions for all versions, if you didn't find it, you can email us at to customize it. 

For the A4 Version, the working area is  210x300mm (8.2*11.8 inch), check UUNA TEK® 1.0 A4 Version here and UUNA TEK® 2.0 A4 Version here.

For the A3 Version, the working area is 420x300mm(16.5*11.8 inch) check UUNA TEK® 1.0 A3 Version here and UUNA TEK® 2.0 A3 Version here.

Thirdly, if you're the Axidraw users and looking for some versions better than Axidraw in writing or drawing, you can follow the guide as follow:

Please check this comparison video made by our users between UUNA TEK® 2.0 and Axidraw SE in which you will find that UUNA TEK® 2.0 is 200% faster than Axidraw SE. 



In a word, if you need a cheaper alternative to Axidraw, you can pick up the UUNA TEK® 1.0 directly, which is only half less price of Axidraw. If you're looking for something better and faster than Axidraw to replace your current work, feel free to pick up any UUNA TEK® 2.0 and UUNA TEK® H Version machines.

Fourthly, With or Without a Basement, What's the Difference?

The basement provides a more stable base when the machine is running at high speed. And the magnetic blocks can hold your paper easily. Generally speaking, you can buy the version with the basement. However, the version without a basement gives you a big customization space, especially if you have an auto-feeding system. 

a. With Basement - UUNA TEK® H A3 Version


With Basement - iDraw H A3 Version
With Basement - UUNA TEK® H A3 Version


b. Without Basement - UUNA TEK® H A3 Version


Without Basement - iDraw H A3 Version
Without Basement -UUNA TEK® H A3 Version


At last, I would like to share the full comparison sheet between those versions as follow:


In a word, UUNA TEK® H version is the most advanced version, UUNA TEK® 2.0 and H versions have better performance in writing, UUNA TEK® 2.0 is 200% faster than Axidraw and UUNA TEK® H is 300% faster than Axidraw at half or less price. UUNA TEK®1.0 is comparable with Axidraw and it performs better in drawing at high speed.
