Description

35K+ and up to 40K ultrasonic vibrations per second ensure smooth, effortless trimming for perfect 3D print finishes. Phrozen Sonic Saber’s pen-shaped design and ultrasonic cutting make support removal precise and easy. Sonic Saber cuts through the supports fast and smoothly without leaving any marks. With Sonic Saber’s accuracy, trimming joints, touching up errors, and refining models is as easy as it gets. With ultrasonic vibration , Sonic Saber precisely cut supports even from narrow gaps that were unreachable with pliers. Sonic Saber cuts through a wide range of materials, allowing you to create and craft any projects across your creative practices. What materials can the ultrasonic cutter handle? Sonic Saber handles more than just 3D resin prints—it’s tested on PVC, leather, acrylic tubes, wood boards, and even thin metal sheets like 0.1mm aluminum. Perfect for post-processing across materials. Removing supports before or after post-processing? Removing supports before makes them easier to remove and allows better cleanup of support marks. However, some users prefer removing supports after curing to maintain better dimensional accuracy. What if the Sonic Saber blade becomes dull over time? The Sonic Saber comes with extra blades and an Allen wrench for easy replacements. When you run out, simply order the Sonic Saber Blade Replacement Kit—includes 20 blades, collets, setscrews and the instruction—to keep every cut sharp and precise. Is it easy to use for beginners? Yes! The pen-style, lightweight design makes it intuitive to handle, even for first-time users. How does ultrasonic cutting improve post-processing? With over 35K+ vibrations per second, it reduces resistance and effort, delivering smooth finishes and clean edges without damaging your prints. Better Than You Envisioned- Unleash Your Creativity and Achieve Perfection in 3D Printing. Phrozen was founded by a group of Taiwanese 3D printing enthusiasts in 2016. We produce professional consumer-friendly 3D printers for industrial application, medical, and personal use.

Excellent with a gentle touch
I’m very satisfied with this tool. It is much more economical than the other one that I was considering. The knife works very well. I would like the cord to be a bit longer but after spending some time with it I’ve gotten used to it as is. A must have for 3d printed parts removal and cleanup. There is a bit of a learning curve with this tool. It melts through styrene and can even melt 3d printed parts. A gentle touch is required to prevent overheating the parts that are being cut. The learning curve is short however as I am now using it successfully with styrene and 3d parts. ... show more

THE GREATEST TOOL YOU WILL EVER OWN!
No doubt you are thrown by the price, I can tell you this is worth it but .... you are still not sure. This thing cuts resin, pla, lexan, plastics, acrylics virtually all softer but rigid composites. It has changed my life and it is worth every penny. OOPS, this tool has been thrown around a lot and still worked. Unfortunately I plugged it into the wrong adapter (double the voltage! ) and killed it. So disappointing but I will mark it so it can never happen again and bought a second one. Still my favorite tool! ... show more

Good tool to have in inventory
Product is over sold. Cuts, but nothing like the videos

Cuts supports easily but also melts plastic
A hot knife through butter. In this case there’s no “like”. The friction heat generated when using the ultrasonic blade melts plastic. It’s great cutting thin supports with ease but beware trying to cut any thicker plastic because you’ll end up with a molten stringy mess, not a clean cut.

Not as advertised
I’ve seen a lot of reviews, some by noted modelers. This unit, at least not mine does not work as advertised. Beautiful unit, well built, quality shows, however mine will not cut anything. Put it on my thin supports for a print and even though I can hear the vibration kind of, it does not cut even with moderate pressure. It will cut if I exert a large pressure, but so will an average X-Acto blade. From what I’ve seen this unit should cut with little or no pressure. Perhaps defective, but I believe it’s past my return time. Wasted time and money in my case and sadly another piece destined for the electronic waste dump. If someone from Phrozen can reach out to me with a resolution I’d be happy to entertain it, and change my review. Thanks in advance ... show more

Worth the price if your 3d printing with resin
I use this to slice through my resin 3d prints, it works wonders. Not quite like butter but will definitely improve your cuts 10 fold. I recommend wearing safety glasses.

Disappointing, not worth the cost
I am an avid 3D printer and modeler, and kept hearing great things about this ultrasonic knife. I took the plunge, and I wish I had returned it while I still could. My experience has been quite underwhelming. If you're expecting to slice through plastic supports like a light saber, look elsewhere. It does cut, but it is slow and requires a steady hand, even for thin FDM material. I have yet to encounter an instance when using my trusty sprue cutters wouldn't have yielded the same result (often faster). To make matters worse, the on button (which you need to keep pressed to activate the knife) is terribly unergonomic and makes the whole operation more difficult than it should. To top it off, the entire unit feels cheap- light plastic, finicky button, it feels like a cheap remote. Again, it works, slowly and uncomfortably, but it is absolutely not worth the price of entry. ... show more

Worth every penny
This was a superb addition for my hobby work with plastic models. I thought it was defective at first because it is completely silent when turned on. I quickly realized that it was working perfectly. Makes excellent cuts in ABS plastic for model building.
