Non-Destructive Testing

Rapid, cost-effective flaw detection for metal AM, conventional metals and composite components.


welcome to Theta Technologies

UK-based engineering company specialising in non-destructive testing of parts produced for critical applications. Our unique nonlinear resonance non-destructive testing technology is capable of safer, cost-effective and rapid flaw detection for manufacturers of a variety of materials including:


The go-to material for manufacturers for decades. Metals have been the building block of most industries thanks to its unrivalled strength and versatility. 

Additive Manufacture

3D printing offers manufacturers greater design freedom, but the increasing geometries and complexities on offer means that existing NDT methods are no longer suitable.


Since the mid 1990s, composites have been widely used in manufacturing processes thanks to its relatively low cost, light weight, and incredible strength.

Introducing RD1-TT

The world’s only nonlinear resonance NDT solution specifically designed with metal additive manufacturing in mind. RD1-TT is not only capable of rapid flaw detection in even the most complex 3D-printed metal parts but can also detect flaws that other NDT solutions cannot see.

Our advantage

Our unique technology offers a number of key advantages over other non-destructive testing methods on the market.


The first NDT solution capable of performing a complete non-destructive test in under one minute.


Unlock the full potential of additive manufacturing with the ability to test metal and composite parts with complex geometry.


Our technology can detect even the smallest of flaws deep within manufactured parts that other NDT methods can’t.
