ThermoChrome Purple-Pink PLA 3D Printer Filament for 3D printers has a unique colour-changing feature - when the material is cold it is deep purple, but as it warms it changes colour to light pink perfect for printing wearable items such as necklaces and wrist straps and bath thermometers.

Robox materials are supplied on a SmartReel which holds data about temperature settings, print speed, diameter and even the amount of filament which has been used on that reel.

As a user this makes printing very easy, you load the filament and AutoMaker will automatically change to the settings saved on the reel.

Robox is able to use filament from any brand (you are not locked into the SmartReel system). Obviously better quality filaments will give more consistent results.

We also stock a wide range of colours and filaments including ABS and PLA. So what is the benefit of ThermoChrome PLA?


  • Filament changes colour when touched/slightly heated (Purple - Pink).
  • Lower plastic smell during print.
  • Less warping of print, so possibly more detail and better visual quality to prints.
  • Biodegradable (when under the right conditions).
