Tungsten Premium Nozzle for precise 3D print results. For abrasive and high temperature print processes where brass & steel fails.
We were not satisfied with the durability and precision of brass nozzles, because as more heat is affecting the nozzle:
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 and so our tungsten premium nozzle was born.
..3D Printers evolve, while crucial main parts of a printer seem to stand still…
more features and advantages:
Why didn’t we make a diamond nozzle? Diamond is actually the most superior material for printer nozzles. But a nozzle completely made of diamond would also cause superior costs. So the general trade-off in this case is that just the tiny nozzle tip will be then made of diamond, while the rest of the nozzle is made of cheaper materials like steel or brass. Such nozzles with a gem nozzle tip are actually used for water jet cutting and sandblaster applications and we think such nozzle design in case of 3D Printing requires too many compromises so if we ever make a diamond nozzle then definitely one without any compromise.
Disadvantages of nozzles with a gem nozzle tip:
Steel is harder than brass and a budget-priced material. But it comes together with some disadvantages:
Already months ago before this kickstarter campaign we introduced our project to the 3D Printing Community and offered free samples worldwide for testing purposes. We announced it on various 3D Printer Magazines and Printer Boards:

Various research institutes, companies and leading figures of the 3D printing community evaluated our nozzles. With their support and feedback we improved our nozzle. The complete promotional event was expensive but it was worth it especially for you backers because it ensures that you will get a reliable and tested premium quality product!
(Other hole sizes or a nozzle for 2.85/3.0mm Filaments will be probably offered after a successful crowdfunding campaign)
Which 3D Printing materials need high temperatures?
Which are typical abrasive 3D Printing materials?
dddmaterial was founded in 2014. We focus on the construction of plastic extruders like our upcoming industrial extruder:
And we focus on the development of 3D Printer Equipment for professional purposes, the manufacturing of 3D Printers and their print materials.
Since 2014 we actively blogging about our projects, 3D Printing and plastic extrusion related topics. Check here our blog.
And in 2015 we introduced our projects to the public on the Maker Faire in Hannover, Germany.

Minimizing risks is one of our main concerns.
Possible risks could occur during transportation that the sending gets lost so all our dispatched nozzles are insured.
Tungsten prices sky-rocketing / Tungsten manufacturer suddenly rises prices. To lower that risk we sourced not just one manufacturer.
The product is not working as intended. If a nozzle is damaged you will get a new one and the nozzle works as promised. To lower such risks in advance we ran a free nozzle samples for feedback promotion before the crowdfunding campaign to ensure that they work as promised.
