  • Main materialPolylactic Acid
  • Product weight1 kg
  • Stronger prints with enhanced toughness versus standard PLA
  • Clog-free extrusion from 24-hour dried, vacuum-sealed spool
  • Less tangling thanks to mechanical winding and larger core

  • Moisture-resistant packaging preserves detail for functional parts

Creality PLA+ Rainbow 1 kg spool

This spool delivers 1 kg of 1.75 mm PLA+ filament in a rainbow colour blend. The material is polylactic acid formulated for higher toughness than standard PLA, so printed parts resist repeated bending without snapping. Each spool is vacuum-sealed with desiccant after 24 hours of drying to prevent moisture uptake.

Makers who want multicolour prints without

The rainbow blend produces colour transitions throughout a single model, which suits decorative items, toys and visual prototypes. Users who need a single solid colour for colour-matched parts or engineering prints should choose a monochrome spool instead.

Diameter tolerance ±0.02 mm at 1.75 mm

The filament is manufactured with CCD measurement and self-adaptive control to hold a tight diameter window, reducing extruder jams and improving layer consistency. This precision is the key factor when deciding whether the spool will work reliably on a given printer.

Questions about this item

Will this 1.75 mm PLA+ spool feed reliably on my older Bowden-style printer?

The 1.75 mm diameter and mechanical winding are designed for smooth feeding on most 3D printers, and the larger spool inner diameter helps reduce drag on Bowden setups.

How can I verify the filament diameter is within tolerance after opening?

The manufacturing process uses CCD measurement with self-adaptive control to hold dimensional accuracy to ±0.02 mm, so a quick spot-check with calipers should confirm consistency.

Does the vacuum-sealed bag include desiccant or do I need to buy a dry box?

Each 1 kg spool is vacuum-sealed with desiccant inside the bag, so it arrives dry and ready to print without extra purchases.
