iDraw H SE A3 Pen Plotter Preassemblato per Arte Generativa, Coding Creativo e Disegno di Precisione

This is the second pen plotter I have owned, and I am thoroughly impressed with the upgrade in quality. The iDraw H SE (A3) feels incredibly solid and the operation is smooth and stable. As the title says, the precision is excellent; it handles complex vector files and fine lines without any issues.

Setting it up was straightforward, and it fits perfectly into my existing Inkscape workflow. If you are looking for a reliable machine that produces consistent, high-quality results, I highly recommend this one. I absolutely love it.

I have been using the iDraw H SE A3 for some time now, and I can say it is a very successful tool for creativity and experimentation. The device turned out to be quite easy to set up. After installing the software, everything works stably. I mainly prepare vector files in Inkscape and then send them to the plotter. The workflow is clear and logical, even for beginners.

The construction feels solid: a metal frame, smooth motion and good line accuracy. The plotter confidently works with different pens and markers, which is convenient for calligraphy, illustration and generative art. I have used it to draw patterns, lettering and educational projects. I especially enjoy watching digital ideas turn into neat drawings on paper. A great choice for artists, designers and techno-art enthusiasts.

P.S. In the photos are my experiments with scratching on rainbow scratch paper.

I've had the iDraw H SE A3 for about half a year now and i absolutely love it. It has reignited my creativity. I write code for a living, but using this pen plotter and exploring materials to plot with and on has been great fun and made coding creative again for me. It was very easy to setup overall. I mainly use the Inkscape plugins or the axidraw CLI to make my plots. I've written my own flow line software, used open source tools, and drawingbotv3. There's a great range of software available to work with. The only feedback I have is that documentation for the existing software and plugins needs to be refined. It wasn't that clearly documented. I think it should be open sourced via GitHub or similar and clearly documented in a README.

I purchased this plotter to explore algorithmic art and I have found it to a workhorse machine so far. Although I was already familiar with CNC devices like 3D printers and CNC routers before purchasing this plotter, I don't think the minimal setup would present an issue for beginners, learning Inkscape itself is more of a challenge :)

I purchased the iDraw H SE A3 model and am referring to it for all comments below.

The homing accuracy and general smoothness of the design is excellent. After 1000+ hours of use I have found no discernible change or looseness to the frame. I have found the self-homing to be perfectly sufficient for producing multicolour/pen drawing.

The magnetic board for mounting the paper is great, makes loading and unloading quick and easy. Some magnets shaped like pawns on a chessboard are a little more ergonomic to work with and work the couple of dollar they cost.

The pen holder is fine but could be improved, the threaded section through which the screw goes could be deeper to encourage the screw to stay straight and true. Overall pen to pen accuracy is fine, although you will need to work out offsets if you change between pen types or brands.

I am still using the Inkscape plugin for all my designs, although I may move to CNC.js on a RasPI in the near future to separate the plotter from my computer. The plugin works fine, if not a little dated and clunky. Inkscape may be a little arcane to learn but it is incredibly powerful given it is free.

Beyond Inkscape, I have also gotten great value out of DrawingBotV3, Paragraphic and both the Processing/P5.js and Python programming languages, these are the tools the will unlock the true potential of your plotter. There are plenty of great communities out there to garner inspiration from.

Pen wise, I have found value in a large multicoloured pack of Staedtler ballpoint pens (432 or 437 even better!) and some cheap alcohol ink markers. Don't feel like you need to spend big on expensive pens, cheap ballpoints can produce incredible works of art in the right hands. A black 0.8 or 1.2mm fibre fine liner is useful for outlining shapes and providing definition.

Overall a great machine that unlocks a world of creative potential, the pleasure it has provided me far outweighs the initial cost already.

I would definitely consider purchasing from uunatek again should I decide to explore a larger platform one day in the future, but for now the A3 feels like the sweet spot in terms of total drawing time and material costs.

The iDraw H SE is an absolute joy to work with, turning the creative process into a truly mesmerizing experience. While there is definitely a learning curve when it comes to dialing in the initial settings, once you familiarize yourself with the workflow, it becomes a breeze to program and draw. There is something incredibly fun and therapeutic about watching the machine meticulously bring your digital designs to life on paper, stroke by stroke. It is a perfect blend of technical precision and artistic satisfaction that makes every project rewarding.

I purchased the iDraw H SE/A3 pen plotter in April 2025 and had it shipped to Europe. Delivery took about one week, and the plotter arrived in a sturdy, well-designed package. The unit was preassembled and ready to use within roughly 15 minutes.

Build quality is very solid and reassuring. The main work surface features a clear grid, and the included magnets are sufficient to hold paper securely in place. Overall, the hardware feels well thought out and robust.

I have been using the plotter with the provided Inkscape extension, so I cannot comment on the Python API. Beyond artistic plotting, I also use it for practical tasks such as labeling envelopes that do not fit into a standard printer, which works smoothly and is very straightforward. The plotter is also precise enough for technical drawings. CAD drawings can be exported as PDFs, imported directly into Inkscape, and plotted without issue, since the geometry is already defined as paths. For optimal text rendering, the embedded PDF fonts should be replaced with single-stroke fonts.

Overall, I am very satisfied with the complete package and can confidently recommend this plotter.

As side notes: the machine does produce noticeable operating noise, so it is not something you would want running during a quiet rest period, and you should allow sufficient vertical clearance for the pen and cable during operation.

I ordered the plotter from Europe, this being my first purchase from another continent I was being a bit worried, but the excellent service from UUNA TEK left me feeling very secure and satisfied. The free delivery took approximately a week from China to Poland, which I would consider fantastic.

The plotter itself is ready to use out of the box, has special additional tools for custom programming of the machine, for now only used with the default inkscape extension, but I'm excited for what's coming in the future.

Thanks to Una for great customer service and instantly responding by email to my every question.

I've been using it for a while now, and it's been an incredible addition to my creative process! The machine is well-built, easy to set up, and delivers impressive precision. It works flawlessly with Inkscape and offers great flexibility, making it perfect for both technical and artistic projects. I take great pleasure in experimenting with different tools and surfaces, and this plotter allows for endless creative exploration.
I��m excited to push its limits even further and try new artistic approaches.

Really sturdy, easy-to-use pen plotter. Packed well and received relatively quickly considering it came from the other side of the world to get to me. Had some issues getting it going initially but support was easy to reach, responsive, and we were able to overcome the issue. Now that it's up and running for me, I have no complaints with it. Accurate, fast, built well, plug-and-play ready, and looks really sleek which is nice for having it out on display. I hope to have it for many years to come.

Having studied the pen plotter market for my first machine I decided on the iDraw A3 HSE. After ordering it took a few days for the machine to be readied for dispatch and I received an email saying it would be with me in the UK in around a week but somehow, to my amazement, it arrived the next day!
It was very well packaged and only needed a few cables plugging in to get going. The build quality is great and construction looks very good plus it��s nice and sturdy. I��ve only plotted on A4 paper so far but have found the bed to be perfectly flat.
It��s really accurate and fast if you want it to be. As with all pen plotters it��s mesmerising to watch.
Being new to pen plotting there��s a lot to learn but there��s a wealth of resources online waiting to be found. I couldn��t get a particular function to work (hidden line removal) but UUNATEK were great and helped me find a solution and now I can do it. There are only a couple of things I��d like to change on it - an on/off button would be nice and, as far as I can see, you can��t use the full A3 area if using an angled pen.
Overall, this is a fantastic pen plotter and I��m really impressed with it.

I have used a cutting plotter before, and have 3D printed some parts so I could also have it do pen plotting. It's less than ideal but gave me a taste of what was possible. I also found the required cutting plotter software frustrating and limited, for example, it could not directly use an SVG file without a tedious multi-step conversion process.

From the start, the iDraw H SE has proven itself to be much better suited for my needs. I do most of my work in Inkscape already, so being able to plot directly without having to switch programs and export/import files is a huge improvement.

The device is also clearly designed to be modified, and I already have some ideas for it: I want to be able to have it hold a calligraphy pen in the same way as a human hand. I can already angle the pen, but I also need that angle to be rotated. For now, I work around this by rotating the drawing in Inkscape and the paper. But in future, I could design something, have it 3D-printed and then simply screw it in place. All that matters is that the screw holes align neatly, it's so simple!

Shipping was pretty fast: package was dispatched from Hong Kong 2 days after I placed the order, and then took 14 days to arrive in the Netherlands. The device came fully assembled and ready to use.

Software was a matter of making sure Inkscape is up-to-date and then dropping some plug-in files into the right folder, as explained in the documentation.

There's perhaps more of a learning curve than with hobbyist devices like the cutting plotter I used before, but that is to be expected when using something for power users and professionals.

The other criticism I have is the price. It's very expensive compared to a cutting plotter. I was able to find plenty of reviews and video walkthroughs of the device, giving me a very good idea what I would get. A minute of searching got me a very good discount code for the device, so I figured I'd give it a shot. Now that I've used it, I'm definitely keeping it.

Attached is a timelapse video of one of the first things I did with the plotter, which was making holiday cards to send out!

This is my first plotter and I cannot say enough good things about it. It arrived perfectly and setup was a breeze, it just took 15 minutes and everything has been working great ever since. I'm really happy with it. The support is also excellent!

I am using the iDraw H SE A3. It is simple and consistent and worked right out of the box! Tech support always answered my emails and the unit is a lot of fun. I use it for generative art programmed through Python. The physical button to pause the drawing mid-stream is very useful for my process. A video is attached here. Also a plus, there were no import fees into the USA.

This machine is very precise, versatile, and user-friendly. As soon as you plug it in, it's ready to make your graphic dreams come true. The assembly screws do require periodic checking, as they tend to loosen in some places due to vibrations, but this only takes a few seconds and doesn't interrupt the satisfying and mesmerizing user experience. It's very versatile and can do many things; the only limit is the artist using it. Shipping arrives very quickly, and our staff will be happy to assist you with everything.

After discovering plotter art on social media, I started working with a small plotter, then a larger model, both Silhouette models, and then I managed to get the Idraw H Se, which is finally on my workbench. This machine is truly well-made and designed with attention to every detail. It arrived in just a few days, and the staff is always available to answer any questions. I'm very happy and proud to have one.
