A1 mini nozzle quick replacement | precise extrusion | durable.for PLA- and PETG- consumables have been tested multiple timesThe smaller the size,the higher precision of model.0.2mm nozzle can endow the Da model with smaller layer Space and a delicate vertical printing surface,making the printing model have high precision.Te smaller the size,the higher model resolution.0.2mm nozzle can squeeze out smaller diameter consumables,giving the printing model a high-resolution horizontal printing surface.tip:Don't use 02mm nozzle to print consumables containing metal or other inorganic particles,as it may cause blockageComparison of different sizes of nozzles: 0.4mm nozzle is the standard nozzle diameter for modern 3D printers, which effectively balances printing quality and printing speed. The A1 series 3D printer adopts a 0.4mm nozzle size.can be printed using a 0.4mm hardened steel nozzle, which is not easily clogged and has good printing quality.It is recommended to use a 0.6mm hardened steel nozzle to print other consumables containing carbon or glass fibers, minimizing the risk of clogging and wear.Specifications: D-0.2/0.4/0.6/0.8mm nozzlePlease note; the physical slightly color difference or difference, does not affect the use, please do not mind, thank you!Material: Metalcolour: BlackPackage Contents: 1 x Hotend KitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
