I used the A1 model for doing architectural drawings of historical buildings. The accuracy and repeatability of the Uuna Tek 3.0 A1 are outstanding. I can run multiple plots with 0.1 mm pens, and each stroke lands precisely on top of the last. The pen pressure is consistent across the entire bed, thanks to the rigid H-frame geometry. I’ve never experienced skipped steps, stalls, or communication drops. My plots often have hundreds of thousands of strokes in an image and it never misses.

This product is excellent. I am very satisfied. I've had another plotter from a different manufacturer before, but this one is much better. When I was a child I read a Disney comic book where Gyro Gearloose invented a painting robot. Now, with my A1 plotter, I've created a computer program that can draw any picture with line art (similar to wood engraving) and even sketch portraits, etc. The only limit is your imagination. Here are some examples I've made: https://pintorzex.com

I purchased the UUNA TEK® iDraw H Version Pen Plotter (A3 Size) after doing a lot of research, and it has exceeded my expectations. As an artist looking to expand my creative tools, this plotter has been a fantastic addition to my studio.

Excellent Build Quality

The H-frame design makes this machine very sturdy and reliable. It feels solid during use, and the A3 working area is perfect for both small and large projects.

Easy to Set Up

The plotter arrived well packaged, with all cables clearly labelled, making assembly simple even for first-time users. I followed an online setup video, which made the process even smoother.

Great Performance

Plotting speeds are fast, and the output is clean and consistent. I use DrawBot (premium version) to prepare my artwork and Inkscape to send files to the plotter—both work perfectly with this model.

Support That Really Helps

I had a few minor issues at the start with uneven printing on one side, but UUNA TEK’s customer support was outstanding. They responded quickly and helped resolve everything. It’s reassuring to know the company stands behind their product.

Overall Recommendation

The UUNA TEK iDraw H A3 is an excellent choice for anyone interested in pen plotting. It’s sturdy, reliable, easy to use, and backed by great support. I’m very happy with my purchase and continue to discover new creative possibilities every day.

Highly recommended for artists, makers, and beginners looking for a quality pen plotter.

This is my new favorite creativity tool! The UUNA TEK Automated Writing & Pen-Plotting Machine bridges the gap between digital and stunning handwritten detail. From personalized notes and envelopes to artistic line drawings and large-format schematics, this precision robot blends craftsmanship with automation; it is the perfect fusion of tech, art, and efficiency: totally addictive and endlessly fun to watch in action. As a bonus, the UUNA TEK level of personalized customer service is truly first-rate!

Delivered faster then expected. Works great so far, easy to install, and still able to pen plot, while laser is mounted.

I’ve been using this handwriting machine for my real estate business, and it’s been a huge time-saver. Once you get familiar with the software, it’s very easy to use and makes batch writing incredibly efficient. I’ve used it for addressing envelopes and even writing out full letters, and everything comes out clean, consistent, and realistic. It’s saved me hours compared to handwriting everything myself, and the quality looks just like natural penmanship. Highly recommend it for anyone doing high-volume mailers or personalized outreach.

I’m genuinely impressed with the UUNA TEK 3.0 A3. The plotter showed up fast, came fully assembled, and I had it up and running within 15 minutes. Even as someone new to pen plotters, I was able to start creating right away. The build quality is solid, no wobble, no cheap parts and the precision and speed are far better than I expected at this price point. What really surprised me is how accessible it feels for beginners while still being powerful enough for more advanced, code driven projects. I’ve already started experimenting with my own generative designs, and the machine handles everything smoothly. The only thing I’m still figuring out is a good way to manage point to point plotting for more technical drawings, but that’s more of a software need than a hardware issue. Overall, this thing has opened up a whole new creative lane for me, and I’m honestly loving it so far.

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.

I’ve been using the UUNA Tek I Auto for a while now, and I’m impressed with what it can do. The machine is well-built, easy to set up, and runs smoothly once you get it dialed in. The handwriting it produces looks remarkably natural, far beyond what you’d expect from a machine.

I’ve used it in two main ways: entering sweepstakes and sending letters to my insurance customers. For sweepstakes, the I Auto has been a time saver since it can handle large volumes of entries quickly and without the fatigue of writing everything by hand. When it comes to customer letters, the handwritten look makes the message feel more personal and genuine, which helps strengthen relationships and improves response rates.

The software is straightforward and flexible, allowing me to adjust fonts, sizes, and layouts so the final product looks unique. Once I created a workflow, the machine handled the rest with very little oversight.

Overall, the UUNA Tek I Auto is reliable, efficient, and versatile. It saves a huge amount of time while producing results that look authentic and professional. It’s a great investment if you want to add a personal touch to large-scale projects.

As the owner of an event and décor company, the personal touch is everything. For years, we spent over 40 hours every single month handwriting letters and envelopes to our clients and partners. It was our favorite way to connect, but it was also our biggest bottleneck, severely limiting our growth. We were stuck.

The UUNA TEK iAuto has completely transformed our business. This machine is the perfect fusion of high-tech efficiency and authentic, personal communication. The setup was straightforward, and the power it unlocked was immediate. We can now produce up to 1,000 perfectly "handwritten" pieces per run, and the most incredible part is that we can use our own signature calligraphy style by importing it as an SVG file. No one can tell the difference—we get all the credit for beautiful, personal outreach without the crippling time investment.

The ability to use variable data from a spreadsheet is seamless and allows us to maintain that crucial one-to-one feeling, even when sending hundreds of letters. This machine has freed up an entire week of work for my team every month, allowing us to focus on strategic growth and client relationships instead of just writing. It's not an exaggeration to say the iAuto is the single best investment we've made in our marketing. If you are a business that values authentic connection but needs to scale, look no further. This is the solution you've been searching for.

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.

Amazing machine making the process of my business 2x faster. Any issues that occur is dealt with quickly by the Uunatek team.

Purchased another 2 machines after testing. I own another pen plotter and have timed the writing on both machines. The iAuto is 2x faster than my other machine which is perfect for what I need it for. Also, customer support is top notch and readily available via email or zoom.
