This Cordless Ultrasonic Cutter is Like a Power X-Acto Knife

Perfect for cleaning up 3D prints

By Rain Noe - November 22

This C1 Ultrasonic Cutter, by Chinese tool manufacturer Hanboost, is designed to make delicate cuts in plastic easy.

The cordless, rechargeable-battery-powered tool vibrates at 40,000 HZ, allowing you to slice with ease; it seems like the ideal tool for cleaning up 3D prints.

It takes standard 30-degree angle hobby knife blades, though changing them does involve an Allen key.

The company claims it'll cut through a lot more than plastic:

The C1 has gone gangbusters on Kickstarter, racking up $522K-plus at press time, with 10 days left to pledge. Prices start at $109.

I have been regularly using a corded ultrasonic cutter made by a Honda subsidiary. It’s a damn game changer, but starts at US$600. Blades are cheap, and the same standard hobby blades you see here. There are also a variety of alternate blades such as a L shape for scooping, flush cutting, etc. Another for ultrasonic welding plastics. One very important thing to note: The set screw that holds the blade in place needs to be tightened to a very specific lb force supposedly. The dealer that I bought this from sold me a Wiha torque wrench for 90 bucks. Wondering if this one requires the same.

  You were well served by your dealer.
  
  Most screws have specific torque requirements. The National Electrical Code specifies torques for some screws used in making electrical connections. The boxes in which some Hubbell AC receptacles are shipped specify that they meet UL standards only if the screws are tightened to a torque of 12-14 inch pounds.
  
  An experiment that has not been published showed that people are extremely poor at estimating torques by feel. The subjects used a torque wrench set to a specific torque in their day to day work. They tried to fasten a large nut to the correct torque without using the torque wrench. With one exception, every person was either over or under by more than 50%. The one exception was a man whose hobby was restoring internal combustion engines.

Until you said Kickstarter.
Also would be infinitely more attractive if it used some form of standard blades. Who knows if they are still around when I need new blades?

  Per the article and Kickstarter, it looks like it takes a standard hobby blade.
