【Phrozen Sonic Saber Unboxing】Seven Unknown Tips for the Phrozen Sonic Saber Ultrasonic Cutter
If you haven't heard of the Sonic Saber Ultrasonic Cutter before, then you're truly missing out on a highly efficient tool that can improve your post-processing, especially when it comes to support removal. In this article, we'll dive deep into everything about this ultrasonic cutter and why so many people are eager to get their hands on it. Let's get started!

Now that your model has finished printing, as part of the entire 3D printing post-processing, it's time to clean and cure it. This includes thoroughly cleaning the model to remove uncured resin, post-curing to ensure the model is fully hardened, removing supports, and even polishing and painting.
Some might find support removal a hassle, especially when creating complex models where support placement is tricky. Too few supports can lead to print failure, while too many or too thick supports can make resin support marks difficult to remove. Therefore, for 3D printing enthusiasts like yourself, finding the right balance through experience and practice is crucial.

The ultrasonic cutter set includes: a pair of cut-resistant gloves (level 5), a user manual, a warranty card, a hex wrench, extra bolts, and some spare blades.
It harnesses the power of ultrasonic cutting – sharp, precision blades vibrating at an astonishing 40,000 times per second, allowing you to easily remove supports. Additionally, it's an excellent tool for trimming and refining prints.

Efficiently remove supports from 3D prints, bye-bye traditional utility knives


Previously, removing supports from 3D prints usually involved tearing them off by hand, or using traditional utility knives, craft knives, or pliers when dealing with fragile parts. This method is cheaper but also more time-consuming, and can be difficult when working with harder resins. Not to mention the small nubs left behind when cutting supports, which leave many support marks that require extensive sanding and polishing, with a high risk of damaging the model and losing details.
Even past tear marks can be fixed with an ultrasonic cutter!

Thanks to the ultrasonic cutter's intuitive pen-like design, you can easily manipulate it to precisely cut the base of supports, thus avoiding tiny, unwanted bumps on the model's surface. The slim blade also helps you reach into the concave and convex areas of the model's surface, making it easy to remove resin support marks.
Let's say you've already removed the supports from your 3D print before post-curing, but there might still be some support marks left from tearing. Simply gently move the blade over the support marks, and you can easily scrape away unwanted marks and even model details.

If you 3D print in a place with fluctuating temperatures, then you, like us, might occasionally experience ill-fitting joints during assembly because protruding parts and holes are overexposed after temperature changes. Considering you've spent hours printing and cleaning these models, this isn't the most pleasant experience, but don't get angry or throw them all away yet!!!
Trimming Overexposed Joints with an Ultrasonic Knife

Slice the overexposed protrusions on the model's parts and carve them away layer by layer until they fit easily into the corresponding holes. With an ultrasonic knife, you can cut printed resin models like cutting room-temperature butter, soft and smooth.
Tested on Other Materials
Leather

One pass isn't enough to cut through leather. It requires 2-3 passes. If you only want to make slight incision details, it's a very useful tool.

Acrylic Tube

It's difficult for a regular utility knife to cut acrylic tubes in 1-2 passes, but the Sonic Saber's high vibration frequency can cut it with ease.
Bamboo Skewers

The multi-purpose knife leaves almost no marks on chopsticks. Even if the Sonic Saber can't cut a bamboo skewer in one go, it immediately leaves a very deep incision on it.
Similar to leather, this is a big advantage if you want to add some details to wooden crafts.

Popsicle Stick

To cut through a popsicle stick, make sure to start at the correct angle and move slowly from the edge. Do not cut directly.
PLA Sheet

Similar to popsicle sticks, using the powerful Sonic Saber may also take some time. It's easier to operate at the correct angle.
Safety Design, Button Control
Despite this knife being as sharp as other utility knives on the market, the ultrasonic knife was designed with your safety in mind from the outset. To activate vibrations, you need to continuously press the button on the pen-shaped part. You might think this is an unnecessary step, to avoid accidentally dropping the tool when you're overly excited about your model. With this feature, at least it won't continue to vibrate and cut everything if it falls.
| Phrozen Ultrasonic Cutter | General Utility Knife |
| Not limited to flat cutting | Requires cutting on a flat surface (with a cutting mat) |
| No force point needed (ultrasonic auto-vibration) | Requires a force point (mainly human-applied force) |
| Relatively time-saving, labor-saving | Relatively time-consuming, labor-intensive |
Time is money!!! The Sonic Saber is a complete two-in-one post-processing tool that can both cut and scrape, saving a lot of time and effort and improving the efficiency of the entire post-processing workflow.
