RAW3D Silk PLA+ 3D Filament 1.75mm 1kg - Rainbow 1

RAW3D Rainbow Silk PLA+ 3D Printer Filament

RAW3D’s Rainbow Silk PLA+ combines the visual impact of multi-colour filament with the durability of PLA+, producing vibrant, glossy prints with smooth layer lines. The filament transitions through colours gradually—approximately every 8 metres—making it ideal for larger prints that benefit from a full gradient effect. Smaller prints may only feature part of the spectrum unless printed in batches.

Manufactured to the same PLA+ specifications as our solid silk range, this filament offers improved toughness, reduced brittleness, and strong layer adhesion. It’s easy to print with and delivers a striking, silken finish straight off the bed.
