PETG Rainbow Filament

PETG Rainbow filament blends the strength of PETG with a smooth colour gradient that flows along the spool, and unlike a flat rainbow print, most of our shades carry a genuine glassy, translucent quality that adds real depth to every print. We currently stock ten gradients, from moody tones like Deep Space and Devouring Soul Red through brighter shifts like Flame and Dreamland, all in 1.75mm and held locally in Australia.

Why Choose PETG Rainbow Filament?

This is not just a colour changing PETG. Most of the range has a real glassy, almost translucent quality that a flat, opaque print cannot match, so you get the visual depth of a gradient plus the strength and durability PETG is known for.

  • A genuine colour shift along the spool, not just a printed pattern
  • Many shades have a glassy or pearlescent quality that adds real depth
  • Full PETG strength and layer adhesion underneath the finish
  • Ten distinct gradients, from moody and dark to bright and vivid

What Prints Suit PETG Rainbow Best?

This one earns its keep on anything meant to show the gradient and glass like quality off:

  • Display models and figurines
  • Vases, planters and homeware
  • Cosplay props and fantasy themed pieces
  • Functional parts that still want to look good

A Few Standouts From the Range

With ten gradients to choose from, here are a few to give you a feel for the range:

  • Deep Space: indigo and cosmic blue with a glassy translucence that genuinely looks like a night sky
  • Devouring Soul Red: a deep, glassy crimson with real menace, built for horror and dark fantasy pieces
  • Dreamland: purple, teal, green and mauve with an almost pearlescent shimmer
  • Flame: vivid orange and red with a glowing ember look
