Hello, I would love to see (hardened?) 0.3 mm nozzles which are designed like those used in airbrush-pistoles.
Such nozzles are wide more precise, even more than a 0.2 nozzle. It will reduce bulging corners and stringing drastically because the tip of the nozzle is so small, that you dont iron the molten plastic around the nozzle. Also you can get really neat details out of it. This would be a big gain for the Bambu-ecosystem.
Can you explain how a .3 nozzle produces better precision than .2 nozzles?
In regard to airbrushes, a .3 Nozzle/Needle combo seems unnecessary since .35 is readily available and really only useful for non-detail work or larger jobs.
Because of its shape. Dont get me wrong. I dont compare a 0.3 to a 0.2 airbrush-nozzle. I compared an airbrush to nozzle to the standart 0.2 nozzle. The tip is extremely small and you need some room to get a steady flow at high speeds. So I prefer a 0.3 mm nozzle shaped as an airbrush-nozzle. The tip of such a nozzle is really tiny. That is pretty helpfull fighting stringing, bulge corners and getting really fine details. Most of the time stringing does not come with too much pressure in the nozzle. Its too much molten plastic being pushed around. Same for the corners but the corners can also being induced at high speeds because of an irregular pressure flow.
The standart settings of many printers uses line widths around 0.42-0.45 mm. Did you ever try the other direction? You can get high quality results with using a 0.4 nozzle and reducing the lw to 0.31 - 0.33 mm in most cases while reducing drastically flow for PLA and PETG. Because of the shrinkage materials like ABS, ASA and so on dont need this. The problem is that if you print thinner, more vibrations will be visible. So you will need to reduce accelerations to around 2000-2500 mm/s2 on the X1C.
As being tested on other printers in a German forum called 3D–Druck-Community you can retain a width of 0.29/0.3 mm while getting great results. There are already nozzles like this, for example the design from Triangle Labs. But they are very prone to being damaged and also you need to be very carefull with them. A one piece design, in the best case even hardened, could be a gamechanger for FDM.
