Faraday's Law- linking electrical charge to electrochemical material change- is a governing principle to Voxel's entire process model.

Nitinol is becoming a critical material for next-generation medical devices because its shape-memory and superelastic behavior enable stents, orthopedic fixation devices, guidewires, and neurovascular tools to flex, compress, deploy, and recover shape inside the body. But those same properties make nitinol difficult to machine, creating demand for non-contact, non-thermal processes like PECM that reduce burrs, recast, tool pressure, and surface-integrity risks.

In this article, we'll identify why HAZ is a prohibitively expensive and challenging problem to solve at scale, and how Voxel's PECM process, by avoiding HAZ, can enable new designs and scalability.

Pulsed electrochemical machining (PECM) is changing how complex components can be manufactured, yet most engineered parts are still designed around the limitations of conventional machining methods such as CNC. Constraints like tool access, line-of-sight machining, and material-dependent cutting behavior often force engineers to simplify internal features, reduce feature density, or compromise critical geometries. In practice, this means many parts are designed for manufactur

Primary manufacturing methods such as CNC and laser drilling have had a storied history of stability and reliability in machining near-net-shape components from tough materials into unique geometries. But it's the secondary post-processing operations where these methods quietly lose both time and control. Voxel's pulsed electrochemical machining (PECM) offers postprocessing capabilities for metal components that are scalable, reliable and precise.

Conventional processes continue to be plagued by burrs and recast layers. In this article, we share why these issues persist, what consequences burrs and recast layers present, and how PECM circumvents them.
