Traditional methods such as micro injection molding or CNC machining are costly and limited by tooling requirements. 3D printing allows for intricate geometries without assembly hassles. This capability reduces both time and effort. It also leads to faster development compared to traditional techniques.
The application areas in which these trends are demonstrated include microneedles, microfluidic chips, and personal medical device miniaturization.
Microneedles
Looking at these in turn, there are various designs of microneedles for different purposes that have been created. Some of them are intended for drug delivery. Others are for collecting skin cells. Some of the foremost micro-3D printing systems available on the market allow for the simultaneous production of hundreds of micro-needles on a single build plate in a matter of hours. This ensures smooth, high-quality, sharp precise tips.
Microfluidic Chips
When it comes to the use of micro-3D printed microfluidic chips, a recent collaboration between Nano Dimension and the Technical University of Munich exemplifies the advantages that exist. We partnered with the institution to develop a scalable droplet microfluidic workflow for generating patient-derived organoids (PDOs) at the Center for Functional Protein Assemblies (CPA). The challenge involved achieving micron-level accuracy in fabricating channels for proper fluid behavior without channel occlusion.
Traditional methods proved laborious and limited in scalability, prompting the adoption of micro-3D printing technology from our Fabrica product line. The successful fabrication of a functional droplet microfluidic device highlighted the benefits of a monolithic design. It simplifies cleaning and sterilization procedures while minimizing inter-experimental variations.
This particular collaboration represents a significant advancement in droplet microfluidics. It promises groundbreaking discoveries in protein assemblies and cancer biology. It also heralds a new era of efficiency and innovation in biomedical research.
