Bambu Lab PLA Basic Cobalt Blue 1 kg – Refill

Product Description

Bambu Lab PLA Basic Cobalt Blue 1 kg – Refill is a high-quality PLA filament in an intense cobalt blue color, wound on a cardboard core without a plastic spool. It is designed for use with the Bambu Lab reusable spool system and is fully compatible with Bambu printers (P1P, P1S, X1, X1C, A1, A1 mini) as well as other FDM printers using PLA.

PLA Basic is designed as a universal material for everyday printing – it has excellent interlayer adhesion, low shrinkage, and minimal deformation. This makes it suitable for beginners and advanced users alike, allowing for fast and reliable printing of models, toys, decorations, prototypes, and technical parts without the need for complex parameter tuning.

Main Advantages

• Refill packaging 1 kg – filament on a cardboard core without a plastic spool, ideal for reusable Bambu spools and more eco-friendly printing.
• Special Cobalt Blue shade (10604) – rich, deep blue color suitable for design parts and attractive prototypes.
• Easy printing – PLA Basic is optimized for stable printing without warping and with very good interlayer adhesion.
• Compatible with AMS / A1 AMS – suitable for multi-color printing, after rewinding/placing on an original Bambu spool with an RFID tag.
• Universal use – models, figures, decorations, cases, prototypes, educational projects, and general functional parts with low mechanical and thermal stress.
• Low odor during printing – PLA is a bio-based polymer with lower odor than many technical plastics.

Recommended Use

• Prototypes and visual models
• Decorations, accessories, stands, covers
• Models for schools, clubs, and education
• Cosmetic and presentation parts in a rich blue color
• Multi-color projects in AMS / A1 AMS (color designation Cobalt Blue, code 10604)

PLA Basic is not suitable for parts exposed to high temperatures (e.g., in a car in the sun) or long-term mechanical stress – for such applications, PETG, ABS, ASA, PA, etc., are more suitable.

Print Settings (approximate)

These parameters are based on Bambu Lab recommendations for PLA Basic filament. Depending on the printer and cooling, fine-tuning may be necessary.

• Nozzle temperature: approx. 190–220 °C
• Bed temperature: approx. 35–60 °C (typically ~50 °C for PLA on Bambu printers)
• Print speed: commonly 50–200 mm/s (Bambu profiles allow for very fast printing due to optimized acceleration values)
• Cooling: high, 80–100% after the first layers
• Retraction: according to printer profile (pre-set in official Bambu profiles)

For the easiest use, it is recommended to use the official "Bambu PLA Basic" profiles in Bambu Studio / OrcaSlicer / PrusaSlicer, or adapt an existing PLA profile on other printers.

Material Properties

• Material: PLA (polylactide)
• Category: standard PLA, easy printing
• Filament diameter: 1,75 mm
• Diameter tolerance: ±0,03 mm (typical value for Bambu Lab PLA Basic)
• Fill weight: 1 kg (without plastic spool)
• Color: Cobalt Blue
• Shade: deep cobalt blue (HEX approximately #0056B8)
• Winding: cardboard core – refill for reusable spool

Mechanical and thermal properties (typical for PLA Basic):

• Density: ~1,24 g/cm³
• Glass transition temperature (Tg): ~55–60 °C
• Impact resistance: comparable to standard PLA, suitable for common use

Stated values are typical and may vary slightly by batch. For precise engineering calculations, we recommend consulting the official PLA Basic technical documentation.

Ecology and Packaging

The Bambu Lab refill concept helps reduce the amount of plastic waste:

• The filament is wound on a paper/cardboard core.
• To use it, simply place the refill into a reusable Bambu spool or onto your own printable spool.
• Less plastic in the packaging means a lower ecological footprint and less waste after the filament is consumed.

Packaging:

• 1× coil of PLA Basic Cobalt Blue refill, 1 kg
• Protective bag with desiccant against moisture

Key Benefits for the Customer

• Space and plastic savings thanks to the refill system
• Seamless compatibility with Bambu Lab printers and their profiles
• High-quality winding and consistent diameter for reliable printing even at high speeds
• Attractive cobalt blue shade, ideal for visible and design parts
• Suitable for beginners – PLA Basic is forgiving of minor setting errors and prints very easily

Key Features:

• Refill packaging 1 kg on a cardboard core, ideal for reusable Bambu spool
• Rich cobalt blue shade (Cobalt Blue 10604) for attractive models and prototypes
• Easy and reliable printing, suitable even for beginners
• Optimized profiles for Bambu Lab printers and AMS / A1 AMS
• Stable diameter 1,75 mm with narrow tolerance for trouble-free filament feeding
• More eco-friendly choice due to less plastic waste
