Demonstrating Capability: The Capacitive Pressure Sensor

To showcase the practical capabilities of the eForge system, Electronic Alchemy recently conducted a compelling demonstration: the design and 3D printing of a fully functional capacitive-driven pressure sensor. This test not only validated the eForge’s technical prowess but also illuminated the streamlined workflow from design to a tangible, working electronic device. The creation of such a sensor, which typically involves multiple manufacturing steps and specialized equipment, was consolidated into a single, efficient additive manufacturing process, highlighting the transformative potential of this technology.

The process began with the design phase, utilizing readily available and user-friendly software. The two-material pressure sensor was meticulously designed on TinkerCAD, a testament to how accessible and intuitive the digital design aspect of additive electronics can be. Once the intricate layout of the sensor’s layers and connections was completed, the design was exported as an OBJ file. This standard file format then served as the blueprint for the next critical step: preparing the print. The OBJ file was imported into a specialized slicing software, a crucial interface that translates the 3D model into a series of printable layers. Within the slicing software, the intricate paths for the eForge’s extruders were calculated, and the specific G-code instructions were generated. These G-code files, containing all the precise movements and material depositions, were then exported to a USB drive, ready for transfer to the eForge system.

Upon transferring the G-code files, the printing process was initiated directly from the eForge’s intuitive interface. The first layer, often the most challenging due to the need for perfect adhesion and consistency, consisted of a resistive material. This layer forms the foundational sensing element of the device. Following the successful deposition of the resistive layer, the system seamlessly switched to printing a layer of capacitive material, precisely placed to interact with the resistive elements. This capacitive layer is fundamental to the sensor’s ability to detect changes in pressure. Finally, the last layer of resistive material was added, completing the electrical connections and encapsulating the functional components. The entire process resulted in a robust and functional pressure sensor, measuring 20 x 25 mm in surface area and 5 mm thick. Remarkably, this sophisticated electronic device took approximately only 9 minutes to print, showcasing the eForge’s efficiency and speed in producing complex, multi-material functional electronics.
