Can I manufacture a 1mm nozzle using 3 D printing?

Can I manufacture a 1mm nozzle using 3 D printing?
June 20, 2016 03:44PM
Hi

I am a newbie here and dont know much about 3D printing. I was wondering if a nozzle with 1mm diameter and 0.8mm length can be manufactured using 3D printing. Conventional nozzles are made out of tungsten carbide and it is difficult to manufacture such short lengths in that manner. Can 3D printing achieve this?

Which nozzles are tungsten carbide? I was aware of a project to make a tungsten carbide 3d printer nozzle but I am not sure it will get off the ground [dddmaterial.com].

Almost all nozzles are brass, good balance between thermal conductivity and machinability. Stainless steel is available to cope with carbon reinforced filaments which chew through brass nozzles.

If you want a 1mm nozzle take a 0.4mm nozzle and a 1mm drill bit and get stuck in.

If you are actually trying to make something from tungsten carbide, the two processes that will work well are grinding and Edm (wire and or sinker). If all you want to do is make a hole in an existing piece of tungsten carbide sinker or hole popper type Edm will do the job.

... of course, you can 3D-print such parts from carbide powder with SLS (Selective-Laser-Sintering) or DLM (Direct-Laser-Melting) - this are common industrial process, so calculate with "industrial prices" too winking smiley

Actually, carbide is very hard to be 3D printed since it is a ceramic. Most tungsten carbide tools are actually tungsten carbide "powder" bonded by cobalt (WC-Co).

Might want to research that one a bit more. It can be done, but if part geometry is conducive to traditional methods cost will be cheaper.

Why not just spend $1.43 USD

instead of spending $100,000 to try to make one

Well if you want to print medium sized parts with lower detail then a 1mm nozzle works well. E3D volcano also a good idea to ensure you can melt the plastic fast enough. But you don't need to buy one or make one just drill a smaller nozzle to 1.0mm and away you go. If the OP had given some indication of what they wanted a tungsten 1mm nozzle for we might be able to help a bit more.

A quick google of "Tungsten carbide nozzle" seems to imply a sandblasting nozzle, though 1mm seems pretty narrow and 0.8mm pretty short... maybe that's the point, they need to make a sand blasting nozzle that's not usually available.

But that's mostly conjecture of course winking smiley
