OzFDM PLA Colour Change filament adds an interactive finish to your 3D prints, shifting between two colours in response to temperature changes. Once the temperature returns to normal, the original colour gradually reappears.

Made from quality PLA, this filament offers reliable bed and layer adhesion, low warping and consistent dimensional stability. It is easy to print with most FDM 3D printers, making it ideal for toys, decorative models, educational projects and creative prints that react to touch and heat.

OzFDM’s PLA Colour Change 1.75 mm filament is the perfect choice for makers who want to add an interactive element to their prints. Designed with temperature responsive properties, the filament changes colour when exposed to heat and gradually returns to its original shade as it cools.

From toys and educational models to decorative designs and creative projects, OzFDM’s PLA Colour Change filament delivers reliable results with a unique finish. With excellent layer adhesion, low warping and consistent 1.75 mm diameter, it is easy to print on a wide range of FDM 3D printers without the need for an enclosure.

The Perfect Filament for Visual Effects

Dynamic Colour Shifting

PLA Colour Change filament delivers stunning, interactive visual transformations compared to standard static filaments, transitioning beautifully based on environmental conditions.
This makes it incredibly engaging and fun to work with, adding a magical, dynamic element to your 3D printed models, toys, and functional gadgets.
You don’t need complex dual extrusion setups to achieve eye catching multi colour results; the filament transitions smoothly on its own as it reacts to external stimuli.
With crisp colour definition and a brilliant surface finish, it is the perfect choice for makers who want to create standout, interactive prints without added complexity.

Beginner Friendly Flow

PLA Colour Change filament is designed to make printing speciality materials effortless, whether you’re just experimenting with effects or fine tuning a final showpiece.
With excellent flow consistency, low warping, and reliable bed adhesion, it allows for smooth, trouble free prints on almost any machine setup.
Even on entry level printers, it delivers precise detail, clean overhangs, and sharp details without demanding constant slicer calibration.
It retains a highly forgiving print profile which means less trial and error, letting you focus entirely on the creative outcome, not troubleshooting.

Minimal Odour

Unlike many engineering grade materials, PLA Colour Change produces minimal odour during printing, making it ideal for creative home studios, classrooms, and offices.
Crafted from plant based resources, it provides a comfortable printing experience without compromising on strength or surface quality.
This low emission formula allows you to print confidently for hours without the harsh chemical smells often associated with advanced visual filaments.
Whether you're prototyping, teaching, or printing in shared spaces, it ensures a smooth workflow that's comfortable and reliable.

PLA Colour Change at a Glance

PLA Colour Change is relatively easy to print, rated 8/10, making it suitable for most FDM printers and a wide range of users.
Its strength and durability are moderate, rated 6/10 and 5/10, so it is better suited to decorative, educational and creative prints than demanding functional parts.
Heat resistance is limited at 4/10, meaning it may soften or lose stability when exposed to elevated temperatures.
UV resistance is also limited at 4/10, while its moisture sensitivity rating of 6/10 means proper dry storage is recommended for consistent results.
