How It Works
PART ENERGISED
The additive manufactured component is excited into resonance using varied amplitude signals. This process exploits the microscopic behaviours of flaws with individual AM components.
FREQUENCIES ASSESSED
RD1-TT’s sophisticated software algorithm works meticulously in the background to compare the part’s response to the differing input signals.
METRICS DELIVERED
Should the nonlinear resonance test show any discrepancies in the response, these differences are weighted and presented as a data metric.

Enables Immediate
Post-Print Inspection
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.
Delivers Rapid
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.
Surface Finish
Agnostic
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.
Allows for
Multi-Stage Testing
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.
Provides
Faster ROI’s
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.
Optimise
Process Parameters
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.
Handles
Complex Geometries
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.
Eliminates
HSE Considerations
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.

Introducing RD1-TT
The advanced non-destructive testing solution for critical application manufacture.
What is Non-destructive Testing?
Detect signs of weakness
NDT is used for examination of a part to ensure it has been manufactured to expectations, without deviation or areas of weakness that could result in failure.
Test without Destruction
Unlike destructive testing where a part is destroyed, a non-destructive test allows you to deploy a viable part for its intended purpose after the inspection process.
Predict part operation
Non-destructive testing ensures that manufactured parts meet rigorous industry standards and can assess their ability to withstand the pressures associated with use.

How RD1-TT compares
X-ray CT scanning has been the go-to NDT solution for manufacturers for decades, but limitations such as relatively poor resolution for large parts, complications with the testing of thick wall components, challenges with alloys such as copper, and the time and cost involved have forced manufacturers to seek alternative test solutions. RD1-TT outperforms X-Ray CT scanning in a number of key areas, making it the ideal cost-effective testing solution for your manufacturing process.
