MEDICAL The outcome In the end, a total of $46,047.60 (ex GST) was spent with two registered providers: Cobalt Design ($44,697.35); and GoProto ($1,350.25). Of this amount, $20,000 was contributed by the BIB voucher and the remaining $26,047.60 was paid by Radetec Diagnostics. According to Dr John Li, CEO of Radetec Diagnostics: “The Build it Better program allowed Radetec Diagnostics to design, experiment with and ultimately create a sensitive, multipurpose reader that is easy to use and can be utilised to quantify the fluorescence from a variety of solid and liquid substrates. The additive manufacturing capabilities available in Victoria today enabled a rapid development of a superior benchtop system ideal for R&D and medical applications.”
The project allowed Radetec to develop the reader just in time for the roll-out of its first product – a COVID-19 antigen point-ofcare rapid test. It allowed for a timely delivery of the entire set of diagnostics devices (reader + test strip) to US-based distribution partners for immediate live trial and evaluation. The roll-out of the COVID-10 test was time-critical – the earlier the better. Another significant outcome from the project is that Radetec has accumulated experience in designing and building a “platform technology reader” that can be used in Radetec’s subsequent products – such as STI tests, cancer biomarker tests, or Parkinson’s disease tests. The reader will only require relatively minor modifications to apply to tests on other diseases. www.amhub.net.au www.cobaltdesign.co www.goproto.com.au www.radetecdiagnostics.com
Additive Manufacturing Hub case study: Kesem Health Digital health company Kesem Health sought assistance from AMTIL’s Additive Manufacturing Hub in the development of the iUFlow urinary monitoring device. Melbourne-based Kesem Health develops and commercialises a digital health medical device and develops artificial intelligence (AI)-enabled solutions in the field of urology. Current methods of assessing patients with urinary dysfunction are time-consuming, expensive, and space-intensive. The current standard of care compromises clinical outcomes and increases the costs associated with diagnosing urinary dysfunction. The solution is the iUFlow, a novel, patented, fully automated, and easy to use bladder monitoring device, implemented on a smartphone platform. The iUFlow device is designed and priced to be used over a period of 48-96 hours as required by the patient’s urologist.
The challenge The project entailed the design and manufacturing of multiple components to further tune the design of iUFlow, utilising additive manufacturing principals of multiple parts of the iUFlow product. This is due to the complexity of the design, which is difficult to achieve by going directly to injection moulding. In addition, the costs and processes involved with a typical injection moulding setup presented a significant barrier to entry. Therefore, it was deemed risky, as well as expensive and slow, to move directly to an injection moulding set-up without first exploring how the physical product might look and feel.
The solution In undertaking the project, the Additive Manufacturing Hub engaged the assistance of a registered service provider, X-Product Pty Ltd, an additive manufacturing provider using 3D SLA printing techniques. This was identified as an excellent way to mitigate many of the above concerns. Kesem Health believed that using additive manufacturing it would be able to reduce the design cycle and therefore reduce the time to market. The project allowance was up to three iterations of several parts, with the final aim of having these products ready to be manufactured at production quality, using advance manufacturing and/or additive manufacturing techniques. It would also enable Kesem to conduct small-scale manufacturing utilising the technology for parts supply without committing to expensive tools. During the project, X-Product supplied prototypes, built the prototype units, assisted with testing, measuring and iterations.
In addition, manufacturing of the product took place, entailing hundreds of parts. Once the initial design was completed, the first prototypes were completed the following day after an overnight 3D printing run. This rapid process allowed Kesem to iterate the concept multiple times in a short period and make key decisions related to size, features and aesthetics. Drastic changes could be realised because it was quick and cheap to simply try again with a alternative design.
How the Additive Manufacturing Hub helped It was predicated that the project would make full use of a $20,000 Build It Better (BIB) voucher co-contribution via the Additive Manufacturing Hub. Gil Hidas, Managing Director of Kesem Health, commented: “The BIB program gave us the perfect opportunity to further explore 3D printing for prototyping and utilising additive technology for manufacturing.”
The outcome Over the course of the project, new features could easily be added and adjusted. It would not have been possible to produce these in a plastic mould as a single part and for the cost and in the time of iteration. The additive process that Kesem used for prototyping allowed it to conduct those experiments easily. Therefore, new features were added to the concept and made their way through to the final product, resulting in an improved design. As a result of the project, Kesem will be being using the additive processes employed in the near future and on an ongoing basis, in addition to using it in small-scale manufacturing. The company is also postponing its investment in injection moulding tooling. www.amhub.net.au www.xproduct.com.au www.iuflow.com
