PLA
PLA (polylactic acid) is a thermoplastic polymer derived from renewable resources, which distinguishes it from other commonly used plastics. PLA is ideal for low-cost prototyping, container manufacturing, and functional parts that carry light loads.

Best for
Añadir un color personalizado y una capa de pintura protectora a las piezas de PLA para prototipado rápido de bajo coste.
Note
Validar la adherencia de la pintura, los límites de enmascarado y la cobertura del recubrimiento en PLA antes de la producción, especialmente alrededor de las interfaces, los bordes y los detalles finos.
Silk Screening
Print method
Single- or multi-color graphics on flat or gently curved surfaces
Best for
Aplicar logotipos, etiquetas o gráficos funcionales en las zonas planas de las piezas de PLA utilizadas para prototipado rápido de bajo coste.
Note
Confirmar el área imprimible, la adherencia de la tinta y el registro gráfico en PLA antes de la producción.

Related & Alternative Materials
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.
SLA · Resins
Standard Resin (White)
SLA · White
Standard Resin (white) has excellent surface details and pure white texture. It is one of the most commonly used resin materials and has excellent dimensional accuracy. This material is suitable for pipe parts, fasteners, electronic product casings, automobile casings and instrument panel components, etc. that require high toughness and heat resistance. Prints come offline and are ready to use, with a matte finish, opaque appearance and precise detail.
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.
