0.4mm Tungsten Carbide Nozzle Orifice Size

[Tom Hsia]

I have a rather early version of the 0.4mm tungsten carbide nozzle (2020-04-15, order number DDK-01082) and the orifice has always seemed a bit oversized when compared with other 0.4mm nozzles. I did not mind it back then because: 1)it worked so well as a 0.6mm nozzle (better than a brass 0.6mm nozzle, in fact. 2) My other 0.4mm hardened nozzles have clogged rather horribly at times.

This nozzle has performed excellently over the years and appears to have had 0 wear despite all the carbon fibre filament I pushed through it.

I wonder whether the current 0.4mm tungsten carbide still have such issues? I can't seem to the get the "contact us" page to work.

From left to right: 0.4mm E3D hardened steel, 0.4mm Dyze tungsten carbide, E3d 0.6mm plated copper.

Thanks!

Hey Tom!

Glad to hear the Tungsten Carbide nozzle is still in great shape!

I do agree with you that the orifice looks like it's bigger than the 0.40mm.

I know that in the first batch, this hole was quite a challenge and at some point we needed to go for a different manufacturing process for the 0.40mm and the original process was not providing the quality we are looking for. The holes needed to be a little bigger than what we wanted.

If you like the quality and performance of this nozzle, I'd suggest getting a 0.60mm as the 0.40mm now is made from a different process.

Ah, so there was a change in manufacuring process?

Well, if the newer batches are truly 0.4mm, I guess I'll get a new 0.4mm nozzle and use my old nozzle as a high-precision 0.6mm. My old 0.4mm Dyze nozzle is somehow my best-performing 0.6mm nozzle, it prints details slightly better than my 0.6mm copper nozzle, and has much better thermals and flow than my hardened steel ones.

Thanks.
