The Filament PETG 5kg – Spectrum

PETG is a material favoured by users who need more than PLA but don't want to deal with the complexities of printing ABS. It combines good mechanical strength with relatively easy printing and no need for an enclosed print chamber. Spectrum The Filament PETG in a 5kg spool is designed primarily for those who print regularly and in larger volumes.

5 kilograms on a single spool means fewer print interruptions, fewer spool changes, and a lower price per kilogram compared to standard 1kg spools. It is suitable for print farms, companies producing functional parts in batches, or anyone who simply doesn't want to order a new spool every week.

The spool is made from recycled plastic with 2nd life certification – a smaller ecological footprint without compromising filament quality. The filament itself comes from European production, which generally means more consistent diameter and stable quality from batch to batch.

Who is it for

• Intensive hobby printers and semi-professionals – if your printers run for hours daily and a 1kg spool only lasts a few weeks, a 5kg spool makes sense both economically and practically.
• Companies and small batch production – PETG works well for functional parts: brackets, covers, connectors, or workshop fixtures. The material handles mechanical stress and contact with common chemicals.
• Print farms – large spools reduce changeover frequency and simplify logistics.

What PETG offers as a material

PETG does not require an enclosed print chamber – it prints on standard FDM printers with a heated bed. Unlike ABS, it warps less and produces fewer fumes. Compared to PLA, it offers better resistance to higher temperatures and mechanical stress.

The downside of PETG is its sensitivity to moisture – if the filament absorbs humidity from the air, it will affect print quality (popping sounds, worse surface finish). We recommend storing it dry, ideally in a bag with silica gel or in a dry box, especially if you won't be using the spool quickly.

Frequently asked questions

Is the 5kg spool compatible with my printer?
The spool is larger than a standard 1kg one. Check the dimensions of your spool holder – some printers may need an external holder or modification.

Do I need to dry PETG before printing?
If the filament is new and sealed, you can print straight away. If it has been exposed to air for a longer period, drying at 60–65 °C for several hours will improve print quality.

What is the difference compared to standard Spectrum PETG?
The Filament is Spectrum's economy line. It offers a good price-to-quality ratio in a practical large spool.
