A wireless ultrasonic cutter built for longer, cooler cutting sessions — launching on Kickstarter in late June 2026.

Most cordless ultrasonic cutters work well for short tasks. But for makers, modelers, and 3D printing users, sustained cutting often exposes the same limitation: heat buildup. When a tool gets hot, output can drop, the cut can become less consistent, and the workflow gets interrupted.

SonicMax built the Slice 10 around that problem. Instead of focusing only on making an ultrasonic cutter cordless, the company redesigned the ultrasonic system, thermal architecture, and battery platform for longer creative sessions.

The Slice 10 is scheduled to launch on Kickstarter in late June 2026, with a Super Early Bird price of $99, an Early Bird tier at $119, and a Kickstarter Special price of $149. The planned retail price is $215.

According to SonicMax, the Slice 10 uses a high-efficiency ultrasonic transducer rated at Q > 500, active cooling, and a replaceable 5,000mAh 21700 battery. In an internal maximum-pressure stress test under comparable load conditions, Slice 10 delivered approximately 70 minutes of cutting time on a single battery, while a tested widely sold competing cordless ultrasonic cutter lasted around 20 minutes and experienced multiple thermal shutdowns. This figure reflects a high-load stress-test scenario, not a guaranteed runtime for every material or use case.

Real-world performance will vary depending on material, cutting pressure, and power setting. But SonicMax says the goal is simple: keep more energy going into the cut, waste less as heat, and make cordless ultrasonic cutting practical for longer maker workflows.

Why Heat Matters for Makers

Wireless ultrasonic cutters are not a new idea. The technology has already earned attention for bringing 40kHz ultrasonic cutting into a compact, cordless format. The challenge is sustained use: heat buildup can limit runtime, trigger protection shutoffs, or affect cut quality on temperature-sensitive materials.

For 3D printing users, this matters especially during support removal, print cleanup, and prototype finishing. Plastics, resin parts, foam, EVA, leather, and model board can all benefit from controlled ultrasonic cutting, but excessive heat can lead to melting, stringing, rough edges, or deformation.

Slice 10 is designed to address that problem through three systems working together: a higher-efficiency ultrasonic transducer, an active cooling system, and a replaceable high-capacity battery platform.

What Makes Slice 10 Different

· High-efficiency ultrasonic system: Q > 500 ultrasonic efficiency, compared with the Q = 150-250 range common in conventional cordless ultrasonic cutter designs. More energy is directed into ultrasonic blade motion, and less is wasted as heat.

· Active cooling system: Built-in active cooling helps move heat away from the transducer and blade area during longer cutting sessions.

· Replaceable 5,000mAh 21700 battery: A user-swappable battery system allows creators to replace the battery in seconds instead of waiting for a full recharge.

· Pass-through fast charging: USB-C charging support allows the tool to be used while plugged in when needed.

· Smart Material Auto-Detection: Onboard sensing reads material feedback and adjusts output power and vibration frequency in real time based on cutting resistance.

· Lift-to-activate auto sensing: The tool wakes when lifted from a surface and powers down when placed back flat, helping reduce unnecessary vibration, battery drain, and wear.

· OLED status display: Shows battery level, output power, working status, fan status, and protection alerts.

· Built-in LED work light: Illuminates the cut line for better visibility during detailed work.

A Tool for 3D Printing Post-Processing

For the 3D printing community, SonicMax positions Slice 10 as a post-processing tool for support removal, print cleanup, model trimming, and prototype finishing. The cutter is designed to work with PLA, PETG, ABS prints, resin parts, foam, EVA, leather, model board, plastic sheet, and similar maker materials.

The Smart Material Auto-Detection system is also relevant to mixed-material workflows. When resistance changes — for example, moving from a lightweight PLA support to a denser printed part — the system adjusts output automatically instead of requiring the user to constantly change settings.

Slice 10 is not intended for metal, glass, ceramic, carbon fiber, thick epoxy materials, or applications that require industrial cutting equipment.

Pricing and Availability

The SonicMax Slice 10 Kickstarter campaign is planned for late June 2026. Interested users can reserve a $1 placeholder to join the priority launch list and receive a first notification when the campaign goes live. Early Bird tiers are limited and will be available on a first-come, first-served basis; the $1 reservation does not guarantee an Early Bird reward slot.

About SonicMax

SonicMax was built on a simple conviction: industrial ultrasonic technology — precise, powerful, and quietly transformative — should not stay hidden behind factory walls. The company develops tools for everyday creators: makers, designers, builders, and problem-solvers who turn ideas into real things with their hands. Slice 10 is SonicMax’s first product.
