H3D, an Australian AI-powered CAD/CAM company, has closed a $5.8 million Series A funding round led by Significant Ventures, with participation from existing investors (including Swinburne University) and new investor Co:Act Capital.
Founded by Dr. Philip Kinsella, co-founder and CTO of Swinburne University, H3D develops fully automated design technology widely used in the hearing industry. Recognizing the technology’s potential in dentistry, the company has strategically expanded beyond audio products.
The Series A funding will accelerate H3D’s deployment in dental laboratories worldwide, addressing industry bottlenecks caused by a shortage of skilled technicians, complex manual CAD software, and inconsistent quality.
H3D plans to use the funds to grow its dental business while strengthening its position in the hearing industry, where its technology supports the production of hearing aids, noise reduction devices, and custom music headphones.
H3D recently launched a smartphone-based scanning solution that leverages computer vision, AI, and augmented reality (AR) to create precise 3D ear scans without traditional molds. This innovative technology enables brands to offer personalized products globally.
“This financing is a key step forward in our vision of AI-driven digital manufacturing,” said CEO Iain Mcleod.
We are combining machine learning, advanced 3D algorithms, and real-time cloud processing to create seamless solutions that benefit dental and hearing care patients.”
Co:Act Capital Partner Kate Eriksson added, “H3D combines vision with world-class technology to deliver real value to customers in the fast-growing hearing and dental markets. We are excited to support their team and leverage their impact.”
