Israeli 3D printed electronics firm Nano Dimension has introduced the event of 3D printed capacitors manufactured utilizing its DragonFly electronics additive manufacturing system.
The capacitors are embedded inside the layers of the corporate’s 3D printed circuit boards (PCBs), which means they will each be 3D printed in a single job, subsequently saving house and eliminating the necessity for meeting. Nano Dimension carried out intensive testing across the 3D printed capacitors to make sure repeatability of the part with the DragonFly system.
“The take a look at outcomes clearly present that with the DragonFly system our prospects can obtain repeatability similar to that of conventional processes in short-run manufacturing of capacitors utilizing 3D printing,” commented Amit Dror, CEO of Nano Dimension.
“Together with excessive accuracy, miniaturization and house saving on the board, these are key elements within the electronics manufacturing course of and subsequent era electronics functions.”

3D printed electronics
Nano Dimension’s DragonFly 3D printer is able to producing custom-made PCBs on-demand. With a number of iterations of the system, the corporate just lately launched the DragonFly LDM (Lights-Out Digital Manufacturing), a DragonFly Professional improve. In an interview, Amit Dror instructed 3D Printing Business “The DragonFly LDM is the subsequent evolutionary step within the DragonFly chain.”
Beginning out with methods that may 3D print multilayer PCBs, Nano Dimension has since expanded its know-how, introducing the fabrication of antennas, capacitors, and “only recently” Dror added, “transformers.” In February 2019, the corporate was granted a patent for its dielectric ink used to fabricate its 3D printing electronics.
Producers and organizations are exploring the potential of 3D printed PCBs utilizing Nano Dimension’s know-how with a purpose to cut back the variety of steps sometimes wanted to make PCBs, and open up new potentialities in electronics. The DragonFly printer has been utilized in many such functions together with radio frequency (RF) house methods, IoT communication gadgets for good properties, and sensor applied sciences.

Saving house on 3D printed PCBs
Capacitors are gadgets utilized in digital circuits to retailer power and electrical cost. They comprise a number of pairs of conductors separated by an insulator. Usually, they’re utilized in digital filters to maintain out undesirable frequencies and noise for a variety of functions, serving to to stabilize energy provide and maintain a gentle voltage within the course of. Nano Dimension states that its capacitors can be utilized in radio-frequency transmission traces, audio processing, radio reception, and energy circuit conditioning.
The corporate examined capacitors with completely different 3D dimensions, with every reportedly demonstrating constant outcomes with statistically validated information. Repeatability checks of the 3D printed capacitors confirmed lower than 1 % variance between the parts. The outcomes are primarily based on over 260 checks with 30 completely different 3D printed capacitor dimensions.
Nano Dimension manufactured the capacitors utilizing the identical dielectric and steel inks carried out to create its 3D printed PCBs, subsequently enabling the combination of the 2 components in a single print job on the DragonFly system. This enables electronics engineers and producers to keep away from a doubtlessly time-consuming and sophisticated meeting course of, lowering the general lead time of conventional manufacturing strategies.
3D printing the capacitors inside the interior layers of the PCBs additionally saves house on the floor of the circuit board. Nano Dimension claims that the diminished footprint falls in keeping with business traits in direction of miniaturization and flatness of digital gadgets for client, industrial and army functions. The additional house facilitates the inclusion of additional practical parts on the floor board, whereas additionally permitting designers to shrink the part measurement.
