Find out how Theta Technologies’ nonlinear resonance non-destructive testing solution can help you identify flaws in complex additive manufactured parts and unlock your path to production at Formnext 2023.

Unleash the power of RD1-TT:

Test complex additive-manufactured parts

Theta Technologies’ nonlinear resonance non-destructive testing solution delivers where others have failed. Here is how RD1-TT can provide you with unrivaled design freedom for additive manufactured parts.

Validate one-off parts

RD1-TT’s ability to perform non-destructive tests without the need for ‘known good’ reference samples helps you fully understand the condition of individual components.

Topological optimisation

RD1-TT is capable of identifying smaller flaws than other NDT methods. Repeatability tests have consistently highlighted the machine’s capabilities to detect flaws as small as 10 microns.

Uncover flaws unique to AM

It’s no secret that AM has had its quality assurance challenges due to a unique set of flaws. RD1-TT all but eradicates these challenges with its unique approach to NDT.

Thank you for visiting us at Formnext!

The team here at Theta Technologies would like to thank you for taking the time to visit us at this year’s Formnext event. Although we are confident that the team covered the benefits of RD1-TT for your additive manufacturing production, we thought we would supply you with some more information to help you understand our technology a little better.

Validate one-off or low run prototype parts

The self-referencing capability of the RD1-TT means that there is no longer a time and cost-intensive process of procuring a set of known condition samples. The RD1-TT doesn’t need to conduct machine learning to determine if a component is flawed or not, it can recognise the features in response spectra making it ideal for prototyping, print parameter optimisation, and validating one-off prints.

Topological optimsation

Unlike other advanced NDT techniques, the resolution limits of the RD1-TT whole-body resonance are yet to be truly defined. 10-micron flaws in test pieces greater than 100 mm have been repeatedly detected by the RD1-TT NLR algorithms. Combining this with the ability to excite complex internal structures means that the part you always wanted to make but couldn’t inspect can now be inspected.

Resonance techniques are often impacted by materials with inherently high levels of damping, however, the RD1-TT has been put to the test by manufacturers producing metallic, polymeric, and ceramic parts in various post-printing conditions and geometries. It can even indicate how strong the bonds are between your polymer and fill matrix!

Metallic AM parts with complex internal geometry are a target for applications like heat exchangers, where a non-conventional casing made of temperature-dissipating materials would provide huge benefits to the end user. That request comes at a cost, however, as metals like Copper – perfect for this application, are dense enough to cause other NDT, such as X-CT, a number of issues. RD1-TT isn’t constrained by that – if we can get the part excited, we can get a nonlinear indication!

Uncover flaws unique to additive manufacturing

Through a combination of detecting nonlinearity and characterising the mechanical properties, RD1-TT is capable of uncovering a wide range of flaw types from a single test.

Nonlinear resonance NDT: identifying flaws in complex 3D printed metal parts.

In the rapidly advancing world of metal additive manufacturing, the quest for an effective non-destructive testing (NDT) solution remains. Heat exchangers, vital in automotive applications, epitomise the intricacy of 3D printed structures. Theta Technologies’ RD1-TT, with its nonlinear resonance NDT technology demonstrates its capability of handling complex metal AM designs and offering swift post-build evaluations.
