Printing with a 0.2 mm nozzle can provide very detailed print quality, allowing you to get excellent tolerances and detail in your models.
We have collected a few Frequently Asked Questions about printing with a 0.2mm nozzle. If you have other questions related to this, feel free to leave a comment and we will update the article.
¶ What models work best with 0.2 mm nozzle?
The 0.2 mm nozzle works best when you need to print models with a lot of detail.
A very common use for 0.2 mm nozzles is printing Tabletop Miniatures
¶ Is the 0.2 mm nozzle abrasion resistant?
The 0.2 mm nozzle is not abrasion resistant, as it is made from Stainless Steel and not Hardened Steel
¶ What filament should be used with 0.2 mm nozzle?
The 0.2 mm nozzle works best with PLA, PETG, ABS and ASA.
It is very important to use filament that does not contain any particulates inside, and to ensure the filament is clean and free of any debris.Our Filament guide wiki article contains more information about the filaments that are compatible with a 0.2mm nozzle
¶ What filament should be avoided with 0.2 mm nozzle?
Filament like PLA Glow in the dark can lead to excessive wear and nozzle clogs.
We also recommend avoiding any filament that contains different particulates inside, like Carbon Fiber (CF), Glass Fiber (GF), Sparkle or Galaxy which contain very small particles that can clog the nozzle.Our Filament guide wiki article contains more information about the filaments that should be avoided with a 0.2 mm nozzle. Please check the article for more complete information.
¶ Can you print Carbon Fiber filament with 0.2 mm nozzles?
It is not recommended to print Carbon Fiber infused filament with a 0.2 mm nozzle.
In most cases, the CF particles are larger than 0.2 mm and will quickly lead to clogs.
¶ How to avoid clogs with 0.2 mm nozzles?
Clogs can be pretty common when printing with 0.2 mm nozzle due to the small orifice where the nozzle is extruded.
Small specks of dust can easily lead to a clogged nozzle.To avoid clogs, we strongly recommend ensuring the extruder is cleaned regularly for any dust or filament debris. It's also recommended to keep the filament in a dust free environment.
Optionally, you can try to use a small piece of foam as a filament cleaner.
¶ How to unclog a 0.2 mm nozzle?
Unclogging a 0.2 mm nozzle can be a bit more complicated considering that you cannot use a regular pin to push it through the tip.
The best way to unclog the 0.2 mm nozzle is by following the Hot hex wrench unclogging method followed by a few repeated cold pulls described in our Wiki.
Avoid overheating the nozzle with a torch, as this can damage the hotend irreparably.
¶ How fast can you print with 0.2 mm nozzles?
The biggest limitation when it comes to the print speed with a 0.2 mm nozzle is the Maximum Volumetric Speed available in Bambu Studio.
Usually, a common value of 2 mm3/s works with most compatible filaments and we recommend caution in increasing that value to print faster.
The hotend heating capability is more than enough for such values, but pushing the filament through a very small nozzle hole can lead to extruder skips, filament grinding or inaccurate extrusion.Please also note there will be an increased time during color changes in multi-color printing, or during the initial calibration which is related to the Maximum Volumetric Speed this nozzle is capable of.
¶ How strong are the models printed with 0.2 mm nozzles?
The main factor which gives a printed model strength is layer bonding.
When printing with the 0.2 mm nozzles, the printer layer lines are very thin leading to less than ideal layer bonding.
This means that most prints will have less strength when printed with a 0.2 mm nozzle, compared to using a 0.4 or 0.6 mm nozzle.
