Rainbow PLA | Refill | Silk Fire | 1kg

🌈 Rainbow Silk Fire PLA – Rosa3D

Rainbow Silk Fire PLA from Rosa3D is made for creators who love vibrant, eye-catching 3D prints. Each refill spool delivers a smooth, glossy finish with a dynamic blend of fiery colours — including deep red, luminous orange, golden yellow, and subtle transitions in between. Thanks to a unique PLA-based formula, prints have a soft sheen and bold colour contrast that shifts throughout the roll.

Each 1000g spool includes over six full colour cycles, while a 170g section typically contains one complete gradient. Depending on your print size and infill density, you can include multiple colours in a single model — making every project visually unique.

Rainbow Silk Fire doesn’t require a closed chamber, high nozzle temperatures, or reduced speeds. It performs well on most consumer-level 3D printers and offers excellent interlayer adhesion, low shrinkage, and odour-free printing.

⚠️ Note: Colour transitions vary by batch. One spool may start with red, another with gold. Slight shade variations are natural and part of the multicolour charm.

🔧 Applications:

Rainbow Silk Fire PLA is ideal for:

• Interior décor – like lampshades, vases, and artistic ornaments

• Gadgets – including pendants, keyrings, and visual accents

🙋‍♂️ FAQs

Q: Do all Rainbow PLA spools have the same colour order?
A: No. Each production batch starts at a different point in the colour cycle. Spools may start with red, orange, or yellow.

Q: Can I use Rainbow Silk Fire PLA with a basic 3D printer?
A: Yes. It prints well on most consumer FDM printers without the need for high temperature or enclosed chambers.

Q: What’s the best way to show the full colour transition?
A: Use larger models or reduced infill so more filament passes through. Vertical or tall prints work especially well.
