🙋‍♂️ FAQs

Q: Do all Rainbow Silk 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 Tropical 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.
