3KG Spools

3 kg Filament Spools for Large Prints and Continuous Production

Standard 3D printer filaments are typically supplied on 1 kg spools, but larger projects and frequent printing can benefit from a bigger format.

A 3 kg filament spool contains three times as much material, allowing longer printing sessions without changing spools. This makes larger spools particularly useful for 3D printing businesses, workshops and users who regularly print with the same material and colour.

Benefits of Large 3 kg Filament Spools

• Fewer filament changes - reduce interruptions during long printing sessions.
• Ideal for large models - print bigger objects without replacing the spool.
• Convenient for batch production - use the same material and colour across multiple prints.
• Less packaging - one large spool instead of three separate 1 kg spools.
• Potential cost savings - larger spools may offer a lower price per kilogram.

Available Materials: PLA and PETG

Our selection includes two popular 3D printing materials in larger spool sizes.

PLA 3 kg - an easy-to-print material suitable for large decorative models, prototypes, architectural models and everyday objects. PLA offers low shrinkage and good surface quality.

PETG 3 kg - a durable option for functional parts, enclosures, brackets and technical applications. PETG provides good impact resistance, strong layer adhesion and higher heat resistance than PLA.

Are 3 kg Spools Compatible with Your Printer?

Before ordering, check whether your printer or filament holder can accommodate the larger spool dimensions and weight.

Many standard spool holders and automatic material feeding systems, including the Bambu Lab AMS, are not designed for 3 kg spools.

An external spool holder with low rotational resistance may be required to ensure smooth and consistent filament feeding.

For users who regularly print large objects or produce multiple parts in the same colour, 3 kg spools offer a practical alternative to standard filament packaging.
