A wireless ultrasonic cutter built for longer, cooler cutting sessions, now live on Kickstarter.
Super Early Bird and Early Bird tiers are limited and available first come, first served, ahead of the $149 Kickstarter price.
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 live on Kickstarter as of August 11, 2026. Kickstarter pricing starts with a Super Early Bird tier at $99, an Early Bird tier at $119, and a standard Kickstarter price of $149. After the campaign, the regular retail price will be $215.
According to SonicMax, the Slice 10 uses a high-efficiency ultrasonic transducer, active cooling, and a replaceable 5,000mAh 21700 battery. In an internal maximum-pressure stress test under comparable load conditions, the Slice 10 delivered up to 70 minutes of continuous cutting on a single battery, while a tested widely sold competing cordless ultrasonic cutter lasted around 20 minutes and experienced multiple thermal shutdowns. In typical intermittent maker workflows, SonicMax puts mixed-use runtime at around 2 to 4 hours per battery. These figures reflect internal testing and are 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
How Slice 10 Compares
Against typical consumer cordless ultrasonic cutters, the Slice 10 is built for sustained, higher-load work rather than short bursts.
| Feature | Typical consumer cordless cutter | SonicMax Slice 10 |
|---|---|---|
| Output power | ~18 to 20W | 40W |
| Thermal management | Passive, heat accumulation | Active internal cooling fan |
| Battery | Proprietary or non-replaceable | Swappable 5,000mAh 21700 |
| Status display | Basic or none | OLED status display |
Comparison based on SonicMax internal testing against a widely sold cordless ultrasonic cutter under comparable load conditions. The 70-minute figure shown above is a continuous high-load stress test; in typical intermittent use, expect roughly 2 to 4 hours per battery. Results vary by material and use.
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. Whether you are finishing prototypes from one of the best 3D printers of 2026 or cleaning up budget prints, the cutter is designed to work with PLA, PETG, and ABS prints, resin parts, foam, EVA, leather, model board, plastic sheet, and similar maker materials.
Because the Slice 10 focuses on higher ultrasonic efficiency and active cooling, it is built to hold consistent performance across longer sessions and a mix of materials, rather than fading as heat builds up during sustained work.
Slice 10 is not intended for metal, glass, ceramic, carbon fiber, thick epoxy materials, or applications that require industrial cutting equipment.

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.
Pricing, tiers, and availability are set by SonicMax and are subject to change. Runtime and performance figures reflect internal stress-test conditions and will vary by material, cutting pressure, and power setting. This article contains sponsored links.
