ESUN PLA+ 1.75mm Purple 1kg Refill Filament

Makers running high-detail FDM prints in purple will appreciate this ESUN PLA+ refill. The 1 kg spool feeds smoothly into printers with a 1.75 mm filament path, and the vacuum-sealed packaging with desiccant keeps moisture out until you are ready to print.

Why choose it

PLA+ enhances standard PLA with improved toughness and layer adhesion. It resists warping better than many PLA blends, so larger flat parts stay flat on the bed. The consistent diameter keeps extrusion steady, reducing the risk of clogs or under-extrusion.

Ideal use cases

• Functional prototypes that need more impact resistance than regular PLA
• Cosplay props and display models with a rich purple finish
• Educational projects where reliable printing matters
• Household tools, brackets, and organisers

Good to know

Store the refill in a dry box or resealable bag with desiccant after opening. The spool fits most standard 3D printer spool holders. No heated enclosure is required, but a consistent ambient temperature helps avoid warping on large prints.
