Titanium has become one of the most important engineering materials across today’s most demanding industries. Its exceptional combination of low weight, high strength, corrosion resistance, and biocompatibility makes it the material of choice for applications where performance, reliability, and long service life are critical. From implantable medical devices to aerospace structures and advanced defense systems, engineers continue to specify titanium when failure is not an option.
Despite its advantages, titanium presents unique manufacturing challenges. Conventional fabrication methods such as CNC machining and laser cutting can be time-consuming, generate significant tool wear, and introduce burrs, distortion, and thermal effects that may compromise the material’s performance. Producing intricate features in thin metal sections can also increase cost and complexity.
PEI provides a different approach through precision chemical etching and photochemical machining. Rather than removing material mechanically, our controlled process selectively etches titanium, producing highly precise components while preserving the material’s original properties. The result is lightweight, high-performance titanium parts with complex geometries, tight tolerances, and exceptional repeatability—without introducing mechanical stress or unwanted heat.
Whether you’re evaluating titanium for a new design or looking to improve manufacturability, this page explains why engineers choose titanium, the grades PEI supports, how our photochemical machining process works, and the industries and applications where etched titanium delivers the greatest value.

Titanium is one of the most capable yet challenging engineering materials to manufacture. Its strength, toughness, and low thermal conductivity make conventional fabrication difficult, particularly when producing thin sections or intricate features. PEI’s photochemical machining process overcomes these challenges by removing material chemically rather than mechanically, allowing engineers to etch titanium with exceptional precision while preserving the material’s original properties.
Unlike traditional fabrication methods that rely on cutting tools or thermal energy, photochemical machining uses digital imaging and controlled chemical etching to produce complex titanium components with outstanding repeatability and dimensional accuracy.
The process begins by applying a light-sensitive photoresist to the titanium sheet. Digital artwork defining the finished component is transferred onto the material using precision imaging technology before exposure to ultraviolet light.
This digital workflow replaces hard tooling entirely, allowing designs to be modified quickly without manufacturing new dies or fixtures. Engineers can rapidly iterate designs while maintaining precise dimensional control from prototype through production.
Following imaging, the exposed titanium is removed using a carefully controlled chemical solution specifically developed for titanium etching.
Historically, chemistries containing hydrofluoric acid have been used within the broader industry to process titanium, although modern manufacturing utilizes tightly controlled proprietary processes designed to deliver exceptional accuracy, consistency, and safety.
Because material removal occurs uniformly across the part, the process creates highly accurate geometries while preserving the surrounding material.
One of the greatest advantages of photochemical machining is that it preserves the titanium’s original characteristics throughout the manufacturing process.
Unlike machining or laser cutting, the process introduces no mechanical force or localized heating. This allows the finished component to retain its strength, fatigue resistance, corrosion resistance, and dimensional stability while achieving intricate features that would be difficult to manufacture using conventional methods.
