Theta Technologies’ Nonlinear Resonance technique, derived from nonlinear acoustics, offers faster, safer, and more cost-effective flaw detection. Microscopic behaviours of flaws within a component are exploited using a controlled excitation process to determine the overall integrity of even the most complex additive manufactured components.
How It Works
The additive manufactured component is excited into resonance using varied amplitude signals. This process exploits the microscopic behaviours of flaws with individual AM components.
RD1-TT’s sophisticated software algorithm works meticulously in the background to compare the part’s response to the differing input signals.
Should the nonlinear resonance test show any discrepancies in the response, these differences are weighted and presented as a data metric.

Unparalleled Quality Assurance
Benefits for Additive Manufacturers
Additive manufacturing has prompted a unique set of quality assurance challenges that have prevented its widespread adoption within critical applications. RD1-TT eradicates the most complex challenges, meaning that additive manufacturers finally have an effective non-destructive testing solution at their disposal. Discover the wealth of benefits that RD1-TT brings.
RD1-TT’s unique ability to test additive manufactured parts immediately after printing offers significant time and cost-saving benefits. No longer add value to flawed parts during post-processing by eliminating them from your workflow at the earliest possible opportunity.
Assessment of Part Integrity
As additive manufacturing processes become faster, so too should the quality assurance of parts. The days of waiting hours, or even days if you ship parts off-site for X-ray CT results, are over. RD1-TT provides a comprehensive overview of an AM part’s integrity in less than a minute.
A significant challenge to additive manufacturing is testing for flaws in components that feature the inherent surface roughness of 3D printing. Nonlinear resonance NDT is unaffected by the limitations of other NDT methods such as dye penetrant and X-ray CT when faced with surface roughness.
The ability to rapidly test your AM components in-house means that RD1-TT can be deployed at multiple stages of your additive manufacturing workflow. Understand your post-processing steps like never before and even identify which stage of the process could be compromising part integrity with RD1-TT.
With a reduced investment requirement and more cost-effective part testing, RD1-TT helps you achieve a much faster return on investment compared to other techniques. Whether your target is increased sales, reduced inventory, or shorter production cycles, RD1-TT provides highly cost-effective testing.
The sensitivity of the RD1-TT means that it can be utilised as a process parameter tool. Stabilise and refine your hot isostatic pressing or chemical finishing processes, with component properties maintained within specified thresholds for optimal performance.
Unlike traditional non-destructive testing methods, nonlinear resonance NDT successfully tests and identifies flaws in even the most complex additive manufactured parts. This benefit provides additive manufacturers with unmatched design freedom, for critical applications that aren’t available through other manufacturing methods.
RD1-TT won’t present your HSE team with an extensive list of risks. There’s no X-rays, ultraviolet lights, fluorescent dyes or other harmful substances that require a complex risk assessment resulting in quick and easy implementation.
Our team of technical specialists have refined the non-destructive testing process in RD1-TT to deliver user-friendly operational experience, minimising the need for advanced training and qualification requirements.
