Frankfurt-based 3D printing startup DDDMaterial has recently launched a Kickstarter crowdfunding campaign for their most recent product: a 3D printer nozzle made of a premium tungsten material.
The company’s founders, German tech innovators, Patrick, Christopher, and Philipp were inspired to develop their own 3D printer nozzle after finding dissatisfaction with the durability and print precisions of existing brass nozzles, especially with abrasive filament materials. With their new Tungsten Premium Nozzle, the tech startup is hoping to introduce a more durable, robust, and affordable 3D printing nozzle onto the market.The idea to make their nozzle from tungsten, a hard, rare metal with an extremely high melting point (3422 °C or 6192 °F), came from the material’s existing use in the plastic industry for making extruder dies.
As the company explains on its Kickstarter page, they essentially scaled down the tungsten extruder dies used in the plastics industry to the size of a standard 3D printer nozzle.Christopher Peterwerth explains, “Professional print-shops, prototyping services and designers want to offer their customers high-quality products at a fair price.
Any failures in their printing machinery will raise the costs, so we had the idea to scale down the tungsten extruder dies of the plastics industry to the size of a common 3D printer nozzle. Our Tungsten Premium Nozzle was born."Because of the material’s strength and high melting point, the 3D printer nozzle developed by DDDMaterial reportedly offers several benefits over regular brass or steel nozzles, such as a higher energy efficiency because of its thermal conductivity; more stable calibration even over the course of long prints; and no extreme tempering effects.
Additionally, the tungsten nozzle has been designed with a flattened nozzle head to prevent the scratching and breaking of the glass print bed.After much research and development, the German startup found that tungsten would be the most beneficial material for creating their nozzle both in terms of quality and in price.
