Short for polylactic acid, PLA is a bioplastic derived from plant-based sources. PLA is the easiest polymer to print and is used by the majority of 3D printer users. Whilst more sustainable than fossil fuel plastics, its important to note than PLA is not biodegradable in soil, home compost or landfill refuting claims by some marketers of PLA filament. To reduce usage of virgin polymers, we work with industry partners to recycle post-industrial PLA waste materials that would otherwise be sent to landfill. All users of rPLA can be satisfied that they are 3D printing sustainably, without compromising on quality.
