Design and evaluation of 3D printed instruments for eye surgery

Additive manufacturing (AM) techniques continue to evolve pushing the boundaries of what is possible to print. For example, a strong benefit of 3D printing is that complex shapes can be printed in advanced, integrated 3D layouts without the need for assembly. However, one of the main drawbacks of 3D printing is the limited manufacturing accuracy, making it difficult to create tight tolerances in miniature high precision applications.

The presentation highlights the results and the lessons learnt during the journey to tackle these two important aspects of 3D printing through the design and development of 3D printed instruments for eye surgery.

A presentation by Kirsten Lussenburg, PhD Researcher at Bio-Inspired Technology (BITE) group at Delft University of Technology.

About Kirsten Lussenburg
Kirsten Lussenburg holds a Master’s degree in Integrated Product Design from the faculty of Industrial Design Engineering at Delft University of Technology, The Netherlands. For her Master’s thesis she researched the viability and sustainability of 3D printed wearable textiles. After graduating she worked as a design engineer at a company specializing in sustainable processing of medical waste, focusing on the design of medical products made from bioplastics.
Currently she is pursuing a PhD in Biomechanical Engineering at the Bio-Inspired Technology (BITE) group at Delft University of Technology. Her research interests include 3D printable instruments for eye surgery, non-assembly 3D printing, and miniaturized mechanisms.

About Bio-Inspired Technology (BITE) group at Delft University of Technology
This group is part of the department of BioMechanical Engineering within the faculty of 3mE. Within the group we strive for the development of innovative technical systems and instruments for minimally invasive surgery, drawing inspiration from extraordinary biological mechanisms. We cooperate with several academic hospitals, biology groups, veterinary hospitals, and companies to achieve our ultimate goal; making the world a little bit healthier.

U 3DMED – 3D Printed eye surgery instruments
This research is part of EU Interreg 2 Seas Mers Zeeën 3D MED: Development and streamlined integration of 3D printing technologies to enable advanced medical treatment and its widespread application.

The goal of this project is to research the possibilities of 3D printing for the advanced design and production of medical devices, in order to improve affordability and accessibility of medical treatment. The benefit of 3D printing is that complex shapes can be created in one single production step, which offers great potential for easy manufacturing and added functionality. The focus will be on developing design methods for complex medical devices with internal mechanisms used in eye surgery, which can be printed as one functioning assembly. This research is executed in collaboration with DORC, the Dutch Ophthalmic Research Centre.

Kirsten Lussenburg is speaker at the 2022 edition of the 3D Medtech Printing Conference, which is part of the 3D Medical Printing Series.
