Top 3 Vital Industrial Applications by Adaptive Micro-Damming Technology
By NSW Marketing Team. Last update on August 15, 2024.
Micro-damming as know as “Micro-DAM”, “Additive Structural Printing” or Micro Dam and Fill, is an adaptive microfluidic barrier printing technology. It unlocks a NEW realm for today’s microelectronic heterogeneous manufacturing, it’s a transformative solution that create limitless possibilities for devices miniaturization and advancement of product uniqueness.
Micro-DAM printing technology build high-aspect ratio microscopic structure onto a confined space of miniaturized devices via industrial grade material such as Ultraviolet-sensitive (UV) polymer. Printable surface includes micro-gaps between components, different height cavities, flat, curvy, protruded surface and etc. It created significant advantages for the revolutionary product design and manufacturing that amplifies market value.
Check out the video above for example of micro-dam (Additive structural “Printing”) in action.
Brief Explanation – What is Micro-DAM?
It is a next-level liquid dispensing application for “printing” microscopic barriers – also known as “Micro Dam and Fill”. High viscosity liquid are stacked layers by layers to create a microstructure similar to a dam barries, these barriers confine and control the spread of liquids, underfill or fluids of a product.
Below are 3 examples of Micro-damming utilization:
1. Light Barrier in Photonics
Witness a tectonic shift of optoelectronics breakthrough, Micro-DAM unleash a groundbreaking market landscape in the photonics industry .
In optoelectronics, Micro-DAM apply as Light barriers on various applications, such as optical sensors and integrated photonics. These barriers ensure light signals are confined and directed into the desired pathways, preventing unwanted optical interference, enhancing the reliability and performance of devices. Additionally, Micro-DAM light barriers could also be utilized as “light splitter” for channeling light signals from single to multichannel.
For these reasons, more possibilities are expanded and it propels the industry into uncharted territory.
2. Dam Barrier for High-density Underfill. (Dam and Fill)
Micro-DAM unfolds a new horizon of microelectronics heterogeneous integration and packaging. It prints a microscopic “wall” to contain the underfilled material within a narrow components footprint to prevent undesirable production defects, such as components failure due to CTE (coefficient of thermal expansion) effects. The width of printed “wall” can be achieved as thin as 100um with a height of 10X aspect ratio at one go.
This technology pushes the boundaries of underfill limitation, it removes conventional packaging restrictions due to material behavior and it helps the industry to resolve long-term challenges in high-density products design and manufacturing.
The graphics below illustrates Micro-DAM Barrier vs Conventional underfill process and how Micro-DAM Barrier effectively contains the underfill material.

3. Micro-DAM for Biotech Industry.
In the wake of pandemic, life-saving healthcare equipment demand has tremendously arised globally. The biotech industry is thriving for more game-changing solutions to fulfill today’s complex market requirement. Therefore, Micro-DAM printing technology plays a vital role for realizing innovative healthcare equipment solutions to cater for emerging market needs for the new biosensors industry.

Micro dams create microchannels and microchambers on biosensors to perform multiple test functions within a single device footprint. The printed micro structures are created by microlines and walls for the purpose of precisely confining and controlling liquid or air flow for the testing devices such as blood diagnostic devices, gas sensors…etc.

Additional Opportunities – Employ for Microscale 3D Printing via industrial proven material
The world of manufacturing and 3D printing continues to push boundaries relentlessly. In this pursuit, Micro-DAMs and Microscale 3D Printing have emerged as transformative technologies.
The integration of industrial proven materials and microscale manufacturing has opened up exceptional material flow control at the microscale, supported by industrial proven materials that provide ultimate reliability during the microscale manufacturing process. This combination enables borderless possibilities for product printing.
Our Micro-dispensing technology can be employed in as 3D printer to “Print” high-resolution microscopic objects when conventional 3D printers cannot achieve fine details using regular filaments. Similarly, Micro-DAMs in small-scale 3D printing, are utilized to control the flow of printing materials, such as polymers or resins, which improves the accuracy and resolution of the printed structures.
The “printing” technology are reshaping and redefining the future of adaptive manufacturing.
