Publications in Science Advances, Advanced Functional Materials, and ACS Sensors

In continued partnership with the Interconnected & Integrated Bioelectronics Lab (I2BL) at the University of California, Los Angeles (UCLA), CY Printing Studio (corresponding: Christopher Yeung) has aided in the design and development of wearable smartwatches and fingerprint scanning platforms that can monitor a user's health and biomarker levels (e.g., caffeine, lactate, glucose, etc.). The publications can be found on Science Advances, Advanced Functional Materials, and ACS Sensors


A  freestanding electrochemical sensing system which simultaneously facilitates sensing and signal interconnection. 


A mediator-free wearable sensing system which bypasses the limitations of conventional enzymatic sensors.


A distributed terminal-based sensing network for non-invasive biomarker data sampling and user identification.

Publication in Biomicrofluidics

CY Printing Studio (corresponding: Christopher Yeung) has partnered with the Interconnected & Integrated Bioelectronics Lab (I2BL) at the University of California, Los Angeles (UCLA) to conduct research on 3D-printed biomedical devices for transdermal drug delivery. The publication was accepted and published in the November 2019 issue of the peer-reviewed journal, Biomicrofluidics. The article is available online. 

Here, for the first time in literature, we devised a fabrication scheme to create hollow microneedles interfaced with microfluidic structures in a single step. Our method utilizes stereolithography 3D-printing and pushes its boundaries (achieving print resolutions below the full width half maximum laser spot size resolution) to create complex architectures with lower cost and higher print speed and throughput than previously reported methods. The presented architectures can be adopted in future biomedical devices to facilitate new modes of operations for transdermal drug delivery applications such as combinational therapy for preclinical testing of biologic treatments.

LightHinge+ Project Sponsored by MSC Software

The LightHinge+ ​is an innovative project that showcases the light-weighting potential for 3D printed automotive components. The LightHinge+ is a redesigned hood hinge that is over 50% lighter than traditionally manufactured counterparts. By using state-of-the-art topology optimization software, EDAG Engineering, voelsalpine, and Simufact worked together to demonstrate the practical application of additive manufacturing technologies in automotive production. Visit the LightHinge+ Project for more information.

CY Printing Studio was sponsored by MSC Software, parent company of Simufact, to create a life-sized prototype of the LightHinge+ for demonstrations at conferences and tradeshows. CY Printing delivered the LightHinge+ prototype at a fraction of the cost found at other 3D printing service providers. Utilizing fused deposition modeling (FDM) and vapor-bath polishing techniques, the LightHinge+ replica achieved a production-quality look and feel.

"Chris' passion and eagerness in all things 3D-printing-related made him very easy and enjoyable to work with. Other companies charged me over $2,000 for this project, but Chris was able to take it on for significantly less. I highly recommend his services!"
