Here, you will learn how Filament is a company with ecology as a fundamental value, and you will learn more about all the definitions, and our products origin!

Bio plastic (PLA)

The bioplastic extracted from corn starch is a particular type of bioplastic made from starch derived from corn. This process begins with the extraction of starch from corn kernels, a renewable and widely available plant resource. The starch is then transformed into plastic through a process of polymerization, where the starch molecules are heated and combined with other substances to form long polymer chains. This bioplastic can then be used for filament spools that we use in our machines.

Bioplastic and wood (PLA Wood)

The manufacturing process of PLA Wood, a wood-bioplastic composite, involves blending PLA pellets (originally filament spools) with wood particles, followed by extrusion through a heated die to form profiles or pellets. After cooling and cutting, the material is ready for use, offering the biodegradable properties of PLA combined with the texture and appearance of wood. We choose to predominantly use this material because it gives our products a distinctive look and a unique feel!

Bioplastic and elephant grass

The manufacturing process of PLA Elephant Grass combines the ecological properties of bioplastic with those of elephant grass. In addition to the biodegradable properties of PLA, the addition of elephant grass offers additional ecological benefits. Elephant grass is a fast-growing and sustainable plant that has a strong carbon absorption capacity, thus helping to reduce greenhouse gas emissions. This composite material therefore provides an ecological alternative for our products while offering a unique appearance and reduced environmental footprint. The composition is 90% bioplastic and 10% elephant grass.


Our providers are using natural pigments. A natural pigment is a coloring substance derived from natural sources such as minerals, plants, fruits, or vegetables. Unlike synthetic pigments, they are extracted from natural materials and are often valued for their durability and low environmental impact. These pigments are used in various industries for their organic appearance and ecological approach, although their availability and stability may vary.


The process of coloring bioplastic to manufacture 3D printing filament spools involves selecting colored pigments, homogeneously mixing them with the base bioplastic, extruding the mixture to form the filament, followed by cooling and winding. This filament then undergoes quality tests to ensure its strength and dimensional stability before being marketed.

Origin of our products

Our products made from PLA bioplastic, PLA Wood, and PLA Elephant Grass are all sourced from the European Union. For instance, our suppliers integrate virtuous practices into their production and adhere to Filament's quality and eco-responsibility standards. Our PLA Wood is manufactured using wood waste sourced from the Vasco region in Spain. The elephant grass used in our Pastel products comes from the Schipoll region in the Netherlands.
