Stampiamo tramite la tecnica dell'alta frequenza.
The maximal printing frequency f pmax of about 3.5 kHz with the smallest printed droplets diameter of about 16 μm can be achieved simultaneously via a normal size nozzle (ID 160 μm). Results show that the maximal printing frequency f pmax can be enhanced by choosing large flow rate with medium duty cycle, such as 180 nl min −1 -50%, and.
Ilse Grace Scheers High frequency, what is it really?
The subharmonic resonance and antiresonance effects which have a final influence on the interface behavior and size of the droplets were found in the case of high working frequency. The droplets' size will fluctuate regularly with the increasing printing frequency induced by the residual vibrations.

QDs absorb the high-frequency light (i.e. UV, blue light) and re-emit light at lower frequencies such as red and green (photo-luminescence).. Recent applications require faster printing speeds, i.e. high frequency multi-drop ejection, which is strongly related to printhead performance. However, the performance of printhead is limited by.

Piezoelectric drop-on-demand inkjet printing is a widely used additive manufacturing technology, in which droplets are ejected from a piezoelectric printhead under certain actuation waveforms to form three-dimensional structures. The crosstalk generated by high- frequency multi-pulse actuation waveforms in the piezoelectric printhead has always been considered detrimental and needs to be.

high frequency by Abbie Matthews on Dribbble
Electrohydrodynamic (EHD) printing is an additive manufacturing technique that allows ultra-high-resolution printing. It is a non-vacuum, direct-writing, non-contact, and mask-less process. EHD printing Reduces the number of fabrication steps, making it more cost-effective and material efficient. EHD printing technology is used to fabricate micro and nanoelectronic devices. EHD printing can be.
