PLA 3D Printer Filament – Grey to Natural by Temperature

This Go 3D PLA filament is like an old-fashioned mood ring.  It starts as grey and changes to a milky-white, natural colour at around 31°C, then changes back to grey when it cools.

PLA 3D printer filaments are considered to be the environmentally-friendly option in 3D printing.  It’s a fully biodegradable thermoplastic that is made from plants.  As such, it does not give off the powerful fumes commonly associated with ABS filaments and can be safely used indoors.

PLA becomes softer when heated and can provide more accurate details on corners if it is actively cooled.  It is not prone to warping, and can therefore be used without a heated print bed.  Many people prefer to line their unheated print bed with painter’s tape to keep their projects from sticking.  PLA 3D printer filaments can be sanded down and painted with acrylic paints.  It is not recommended, however, to glue multiple pieces together to create larger objects when using PLA filament.  The bonds will not be strong and might be prone to break.  If you’re looking to glue your prints together, please see our large selection of ABS filaments.

This 3D printer filament comes in 1kg packages and is available in 1.75mm and 3mm.  Not sure which color or gauge will work best for you?  Check out our selection of sample filaments, so you can try it out before you commit.
