Nozzle Wiper Kit	This component is used for cleaning nozzles.
Chamber Heating Kit	This component is used to increase the chamber temperature during sealed printing.
Filament Tangle Detection Device	Used to detect whether consumables are entangled.
Touch Screen	Display printing parameters and control the printer.
Chamber Circulation	The fan in the back of the printer which pulls air from inside the chamber, in order to regulate the inside air and ensure it does not over a specific temperature.
PEI Magnetic Build Plate	It is made by coating a stainless steel sheet with a layer of PEI powder, creating a textured surface on both sides. What sets it apart is its special rough texture, which is transferred to the bottom surface of your prints. This plate works well with a variety of materials and often provides excellent adhesion without the need for adhesives, making it user-friendly. Additionally, the PEI coating on the plates is durable and has a long lifespan.

Glue Stick for Build Plate	The glue stick creates a thin layer of adhesive on the build plate, providing a better grip for the printed object. To use a glue stick, you typically apply a thin layer of glue evenly across the build plate. After the print is completed and the build plate has cooled down, the printed object can usually be easily removed from the build plate.
Lubricant Grease and Lubricant Oil	Lubricant Grease is used for lubricating lead screws or eliminating noise issues between belts and idler pulleys. Lubricant Oil is typically used for the lubrication of linear guides, slide rails, and steel shafts.
