0.25mm nozzle

[int2str]

Has anybody here used the 0.25mm nozzle (available for the E3D)?

What layer heights are you using for it?
Would 0.2mm layer height work? Or is that too much?

What extrusion width are you going for with this nozzle? 0.3mm?

Thanks!

Layer heights shouldn't be more than 80% of the nozzle size. So for a .25 nozzle, .2mm layers is about what you should use.

Extrusion width will likely be 110% -120% of nozzle size. The best way to determine width is to extrude the hot filament into the air, let it cool
measure it with calipers and use the result as your width.

I haven't used the E3D 0.25mm nozzle yet, but I did buy a 0.25mm nozzle from a different website (QUBD) and I've been using it with the E3D hotend because the threads on the nozzle are the same as the threads on the E3D nozzle. The QUBD nozzle was $4.50, which is about 1/3 the price of the E3D one.

I slice with Cura using 0.25mm as the nozzle diameter. 0.2 layer height will work fine, but the point of having a fine nozzle is for fine prints, so I usually do 0.1mm layers.

I switched to the 0.25mm nozzle about a month ago, and I have been getting excellent results since then. Retraction blobbing is almost nonexistent, and print quality is good enough for aesthetic models.

Although I don't remember the source, I have read that the heat break from the MBE v9 extruder will fit the E3D. I have not tried it, yet.

Back in business with the 0.25mm nozzle.

Printing at a layer height of 0.1666mm and an extrusion width of 0.3mm, the top layer surface finish is absolutely awesome! The top now looks almost as smooth and nice as the bottom. Printing takes a long time now (of course), but the resulting finish is excellent.

Attached calibration cube shows the top layer finish pretty well (looks even better IRL).
My bridging parameters are all messed up for now, but other than that, print quality is great.

That is amazing quality! I could see using that on critical parts such as gears etc. It takes a long time to print as you have said but that is one of the best prints I have ever seen.

That is a fantastic looking part. I just started printing with the .7mm E3D nozzle today. I have the .25 sitting here. I'm now excited to try it out.
