ASA
Bambu ASA is a highly durable material with excellent UV, weather resistance, mechanical and thermal resistance. Its unique combination of properties makes it an ideal material for printing outdoor models (plant signs, mailboxes, weathervanes, etc.) and structural components that require long-term exposure to harsh outdoor environments.

Related & Alternative Materials
FDM · Standard Plastics
ABS
FDM · Black & White
Known for its durability, strength and heat resistance, ABS is ideal for parts that need to withstand stress or impact, such as pipes or housings for electrical components. It is recommended to use a closed environment when printing ABS to prevent deformation and ensure stable print quality. Bambu Lab ABS is a versatile consumable material with excellent strength that enables the manufacture of durable and long-lasting parts. It offers significant improvements in strength and durability compared to PLA and PETG, especially when printing in enclosed printers.
FDM · Standard Plastics
PETG
FDM · Black & White
PETG is a strong and durable plastic similar to ABS, but harmless to human health. PETG is made from polyethylene terephthalate (PET), one of the most common synthetic materials, and modified with ethylene glycol. Therefore, PETG is stiffer, stiffer, more precise, and easier to use in 3D printing and processing than PET.
FDM · Engineering Plastics
PC
FDM · White
PolyMaxTM PC is a high-performance polycarbonate filament with excellent strength, toughness, heat resistance and print quality. It is ideal for engineering applications. For example, it is used in the automotive industry to print air ducts using FDM technology.
