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
Ajouter une couleur personnalisée et une couche de peinture protectrice aux pièces en PLA pour prototypage rapide à faible coût.
Note
Valider l'adhérence de la peinture, les limites de masquage et la couverture du revêtement sur PLA avant la production, en particulier autour des interfaces, des bords et des détails fins.

Print method
Single- or multi-color graphics on flat or gently curved surfaces
Best for
Appliquer des logos, des étiquettes ou des graphiques fonctionnels sur les zones planes des pièces en PLA utilisées pour prototypage rapide à faible coût.
Note
Confirmer la zone imprimable, l'adhérence de l'encre et le repérage graphique sur PLA avant la production.

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.
