Latest Patents

Vandepoll's latest patents include a method for forming tapered inkjet nozzles and a mask design for the same purpose. The method utilizes a single mask to create a tapered nozzle in a polymer nozzle member through laser ablation. In this innovative approach, the mask features clear portions that correspond to the nozzle pattern, incorporating a variable-density dot pattern. The opaque dots in the mask partially shield the underlying polymer from laser energy, allowing for precise control over the ablation depth. This technique enables the central portion of each nozzle to be completely ablated, while the peripheral areas are only partially ablated, resulting in a tapered shape. Other mask patterns are also described in his patents, showcasing the versatility of his designs.
