ander will delve into these four key growth areas. 3D printing
will enable the creation of customized implants, prosthetics, and
even bioprinted tissues, tailored to each patient's unique needs.
3D scanning will ensure the accuracy of these medical devices,
leading to improved outcomes.
XR technologies will offer immersive training for surgeons,
such as real-time data overlays during procedures,
and interactive patient education, fostering a more informed
and empowered patient experience and facilitating
remote collaboration, potentially improving access to specialists
in underserved areas. Finally, AI will change the
game of healthcare delivery when it comes to automation,
education and training, patient interaction, and digital
healthcare applications. By exploring the future directions
of these technologies, this view highlights their potential to
significantly improve patient outcomes, reduce healthcare
costs, and personalize medical care. This glimpse into a
" printed " future paints a picture of a more efficient, effective,
and accessible healthcare system, paving the way for a
healthier tomorrow.

Automating Excellence: How LLMs and Generative AI
Transform Medical Device Design
The development of medical devices system is highly complex
and dynamic, requiring systems engineers to understand
and apply a vast amount of domain knowledge from multiple
engineering disciplines to meet design requirements. However,
it is challenging for individual human engineers to fully
and deeply process and apply all this domain knowledge. It's
time-consuming, error-prone and requires proper training,
which leads to high development costs and projects delays. In
this presentation, we will share an AI-driven Intelligent Design
solution to demonstrate how it addresses the above challenges
by automating the manual process of analyzing the requirements
as well as generating the comprehensive design
testing scenarios considering interoperability of various design
entities. To be specific, the intelligent solution will be
applied to the following areas: 1) Design requirements: industry
standards, FDA guidance, product requirements, 2) lower-level
requirements across software, hardware, mechanical,
and electrical. 3) design entities including but not limited to
hardware, human behaviors, environmental elements, and cybersecurity.
Xiaofan Mai, CEO and founder at IntelliU, will
share case studies that demonstrate the solution's capabilities
and benefits. It empowers engineers to transform product development
to the next level, saving business much development
cost by preventing failures early on and expediting the
development cycle with quality excellence.
Biodegradable and Implantable Elastomers
Biodegradable and implantable elastomers are highly desirable
for medical products in which materials interface with
soft tissues subjected to large and dynamic strains. They exhibit
elastomeric properties in both dry and wet environments

and stretched specimens can completely recover after force is
removed. These elastomers are degradable in vitro and in
vivo, and both the polymers and their degradation products
show high cytocompatibility in vitro. Specimens implanted in
the gluteal muscle of rats trigger similar tissue responses as
compared with poly(glycerol sebacate) (PGS) and PCL controls,
two widely accepted implantable polymers. PCLPβMδVL-PCL
can be readily processed by printing, extrusion,
or hot-pressing at 60 °C, and lysozyme can be incorporated
during processing without losing its bioactivity. The elastomeric,
biodegradable, biocompatible, and thermoplastic
properties collectively make these materials highly valuable
for biomedical applications. This session is presented by Wei
Shen, associate professor in the department of biomedical engineering
at the University of Minnesota.
