What can this ultrasonic cutter cut?

It is rated for plastic up to 3mm, acrylic 4mm, 3D resin 5mm, wood 4mm, leather 3mm, PCB 2mm, carbon fiber 2mm and rubber 5mm. Thicker stock is beyond its range.

How is it different from a hobby knife?

The blade vibrates at 40kHz, so it slices with light pressure instead of force. That gives cleaner edges on resin and plastic and less hand strain on long trimming jobs.

What do the four modes do?

They are off, low pulse, high pulse and auto high. Lower settings suit thin or delicate material; higher settings cut faster on denser stock.

What comes in the box?

The cutter, 50 replacement blades, grinding and polishing accessories, a power adapter, tools and a storage case.

Is it good for 3D printing cleanup?

Yes. It is aimed at trimming resin gates, deburring and shaping small features, which cuts down on manual sanding and speeds up assembly.

Does it need special blades?

It uses its own replacement blades, and 50 are included. Plan to restock them as edges dull with use.

Our take on the 40kHz Ultrasonic Cutter Knife with OLED Display

This is a handheld ultrasonic cutting tool that vibrates a blade at 40kHz to slice and trim plastics, resin, wood, leather and thin PCB or carbon fiber. Output is adjustable from 10W to 30W across four modes (off, low pulse, high pulse, auto high), and an OLED screen plus built-in lighting help with fine work. It suits 3D printing cleanup, model building and precision DIY, where it competes with rotary tools and hobby knives by cutting with vibration instead of force. The kit adds 50 replacement blades, polishing accessories and a storage case, so it is a fuller package than bare ultrasonic cutters.
