Acouprint – Next-Generation 3D Ultrasonic Printing for Advanced Medical Implants

The emerging platform technology targets high-precision fabrication for custom medical implants, while holding significant, fast-scalable potential in broader industrial applications.

Addressing the limitations of current technologies

Current 3D printing methods can produce highly complex objects, but they still have limitations in demanding applications. For example, producing bioimplants with locally controlled porosity can be slow and expensive or in many cases impossible. Typically methods build objects layer by layer, not printing volumetrically also within the object. The range of biocompatible materials that can be printed is also limited.

Acouprint addresses these challenges with a new technology that uses AI-controlled ultrasound fields. It enables an entire object to be formed directly into its final shape. The method has the potential to make 3D printing more efficient across a range of industries and expand the variety of materials that can be printed. It could, for example, enable the production of patient-specific bone and cartilage implants designed to interact with the human body.

Built on decades of fundamental research

The Acouprint innovation is based on decades of ultrasound research at the Department of Physics at the University of Helsinki. The research groups have also worked closely with companies, helping to advance the technology towards commercialisation.

At the heart of Acouprint are AI-controlled ultrasound fields. The fields are precisely focused inside the printing material, where their energy melts the material at selected points. This makes it possible to produce complex and porous structures.

The key IP has been protected. The team has also demonstrated that cells can survive and proliferate in biological structures produced using Acouprint. The team is now developing the pilot device, which will be tested and further developed together with partners.

Aiming for major efficiency gains

Interviews with healthcare professionals and surgeons have identified a need for new and more efficient solutions for treating injuries. Acouprint technology has clear potential to address this need. 

The technology that can be used to produce patient-specific bioimplants efficiently can also significantly reduce healthcare costs. Currently, such implants are usually made manually using the patient’s own tissue, which is a process that consumes extensively expert personnel resources.

The Acouprint team estimates that the method could improve 3D printing efficiency by more than 90%. Beyond healthcare, the solution also has potential across other industries. One possible application, for example, is the production of filters for environmental technologies.

Acouprint aims to make 3D printing rapid and reliable by utilizing complex acoustic fields with no moving parts. We hope to improve the quality of life of people by providing new tools for creation of medical implants.

Commercial potential – targeting the growing 3D bioprinting market

Acouprint is primarily targeting the healthcare and biotechnology markets as well as related sectors. The global 3D bioprinting market, for example,  at approximately USD 3.1 billion in 2025 and is projected to grow to USD 6.7 billion by 2033.

Future plans

Acouprint has received Research to Business funding from Business Finland to support the commercialisation of the innovation. During 2027, the eight-member team aims to raise funding to begin scaling towards production phase, obtaining the necessary medical device approvals, and building partnerships to bring the technology to market. The most suitable route to market will depend on the specific sectors in which the technology is applied.

Summary

Acouprint is developing a new type of 3D printing technology that uses AI-controlled ultrasound fields to produce three-dimensional objects. The method could speed up the printing of demanding structures and enable the use of a wider range of materials. Particularly promising applications can be found in healthcare and biotechnology, where Acouprint could in the future enable the production of patient-specific bone and cartilage implants.

Join the collaboration

The University of Helsinki's commercialisation projects offer opportunities for collaboration across a wide range of industries and technology domains. We are interested in connecting with industry partners, investors, funding organisations, and potential customers to explore co-development, validation, piloting, licensing, venture creation, and other pathways to market.
