Unlock your manufacturing potential with nonlinear resonance NDT

With the rapid advancements and growing relevance of 3D printing for critical applications, employing a cutting-edge non-destructive testing solution is the key to your success. Look no further than our groundbreaking nonlinear resonance technology which offers unparalleled benefits, surpassing traditional NDT methods, and ensuring your parts meet the highest standards of quality and integrity.

Beyond the surface.

Tackling the challenges of complex surface finish.

Non-Destructive Testing (NDT) techniques can encounter challenges when dealing with a variety of surface finishes. The effectiveness of certain NDT methods, such as visual inspection or liquid penetrant testing, can be hindered by surfaces with complex textures, roughness, or irregularities and require smooth surfaces to deliver reliable test results. Similarly, rough or uneven surfaces can impede the proper application and removal of liquid penetrant materials, affecting the accuracy of defect detection. Our Nonlinear resonance NDT technology is unaffected by surface finish meaning that we can successfully examine the internal structure of products made with a range of materials.

Detecting the undetectable.

Uncovering hidden defects that other NDT methods cannot see.

Nonlinear resonance NDT has the capability to detect flaws and assess material conditions that other NDT techniques may struggle to identify. The technique can detect and characterize early-stage damage, such as microcracks or fatigue-induced defects, which may be too small or subtle to be detected by conventional linear NDT techniques. Nonlinear resonance is particularly sensitive to small defects or variations in material properties. Even minor changes in the material’s internal structure or properties can lead to observable nonlinear effects in the response signals. This sensitivity allows for the detection and differentiation of smaller or hidden flaws that may go undetected by other NDT methods.

Rapid precision.

Delivering fast, reliable, and accurate NDT results.

RD1-TT can deliver reliable pass/fail NDT test results in under one minute. This rapid NDT method allows for quicker inspection and evaluation of components or products. This leads to increased productivity by reducing inspection time and enabling faster turnaround in manufacturing processes. Manufacturers can streamline their production lines, minimize bottlenecks, and enhance overall operational efficiency. By reducing inspection time, manufacturers can also allocate resources more efficiently, optimize labour utilisation, and potentially reduce production downtime. Additionally, faster inspections can help identify defects or issues early in the manufacturing process, preventing further costly production of faulty components.

Self-referencing inspection.

Operate without the need for reference samples.

Our Self-referencing NDT technology means that a material or structure is used as its own reference or baseline for inspection and evaluation. Instead of comparing the test object to an external reference standard, self-referencing NDT relies on analysing changes or deviations within the material or structure itself. By eliminating the need for external reference standards, nonlinear resonance NDT can provide a more direct and accurate assessment of the condition and integrity of a material or structure. It allows for ongoing monitoring and detection of changes over time, enabling proactive maintenance or repair actions to be taken before significant issues arise.

User-friendly NDT.

Simplicity meets unparalleled efficiency.

We’ve simplified the non-destructive testing process, which means tests can be performed without the presence of highly skilled operators. The lack of requirements for non-specialised personnel reduces the need for hiring or outsourcing highly skilled engineers, which can be costly. Companies can allocate their resources more efficiently and potentially reduce overall inspection and maintenance costs. Nonlinear resonance NDT also makes it easier for a broader range of individuals to perform inspections and evaluations. This increased accessibility allows for wider implementation of NDT practices across different industries, including smaller businesses or organizations that may not have the resources to employ specialised personnel. Operators can be trained relatively quickly to perform a non-destructive test using RD1-TT and this allows for faster deployment of inspection procedures and enables prompt response to routine maintenance or quality control requirements.

Built for scale manufacture.

The perfect NDT solution for manufacturing at scale.

RD1-TT’s rapid test speed and streamlined operation make this the perfect solution for scale manufacturing. Where much slower NDT methods have reduced manufacturers to testing samples of the production, RD1-TT allows you to test 100% of manufactured parts. If you’re embracing additive manufacturing as your primary method, immediate post-printing inspection allows you to test 100% of parts prior to undertaking costly post-processing procedures; all but eradicating the possibility of adding value to defective components.

How it works

Metal components have a characteristic signature which is influenced by factors such as the shape and size of the part’s features. Nonlinear resonance allows us to exploit the fact that the signature of a flawed part changes as we excite it with sound waves. The process can be broken down into three simple steps.

Excitation

We excite a metal component into resonance. A part that contains internal flaws will send back a nonlinear response during this excitation.

Measure

We measure the signal that returns to the detector to identify whether a metal component contains internal flaws.

Results

Our simple pass/fail test results quickly identify whether a component is flawed immediately after printing, preventing you from wasting time and money adding value.

the choice is yours

Our NDT technology has been specifically designed to offer more choice and flexibility for manufacturers.

Test on the platform

Our unique nonlinear resonance technology allows you to perform a non-destructive test of your AM metal part immediately after printing. This helps you identify any issues with the print prior to undertaking any costly post-processing steps.

Test off the platform

Would you prefer to test your 3D-printed metal parts without the build plate? The choice is yours! Our non-destructive testing technology gives you both options and can be performed at multiple stages in your production workflow.
