MEDICAL MICRO-DEVICES & MICROROBOTICS
Applications
Create complex micro-medical devices with our 3D-micro-printing system microFAB-3D. It allows for the creation of complex micro-medical devices, such as stents, mobile micro-robots, and even solid or hollow microneedles arrays. Biocompatible materials and even medical devices certified photoresists are available for use with our microFAB-3D systems, to create tomorrow’s innovative systems.

Highlight
Integrating magnetic materials inside 3D-micro-printed structures makes their remote actuation with an external magnetic field possible. However, the nature of the magnetic material, its volume, and precise position in the structure are keys for the efficiency, dexterity, and compatibility with optical or biological functions. Herein, an original approach consists in the bonding of discrete and fully magnetic microbeads to unaffected 3D-microprinted structures.
This led to the creation of remotely controllable 100µm long micro-tweezers that can be translated, rotated, and opened with a single variable external magnetic field. The dexterity of this untethered micromanipulator allows a pick-and-place operation of 40-µm objects in a confined environment, and could open new perspectives for personalized and targeted medicine applications. Else, the demonstration of remotely controllable micro-lenses opens new perspectives for the creation of new innovative endoscopes.
