Polylactic Acid PLA

Polylactic Acid, more commonly known as PLA, is a biodegradable plastic derived from renewable resources such as corn starch, tapioca roots, or sugarcane. PLA is one of the most popular and sustainable materials for 3D printing today because it can be composted at commercial facilities, reducing the amount of waste that ends up in landfills. Its ease of use and low environmental impact make it a favorite among both hobbyists and professionals.

Recycled PETG

Recycled Polyethylene Terephthalate Glycol-modified (PETG) is a variant of PET, the most common plastic used for consumer goods. PETG is modified to have glycol added, which makes it clearer, less brittle, and easier to use in 3D printing. Using recycled PETG not only makes use of existing plastic waste but also offers excellent mechanical properties and durability for 3D printed objects.

Wood Filaments

Wood filaments blend a PLA base with wood dust, cork, or other powdered wood derivatives, creating prints that resemble real wood both in appearance and smell. The content of actual wood in these filaments can vary, but they offer an eco-friendly option for producing wooden-like objects without the need for cutting down trees. This makes wood filaments a sustainable choice for decorative items, prototypes, and functional parts.

Algix 3D

Algix 3D is a unique filament made from algae harvested from bodies of water at risk of algal bloom. The process of making this filament helps clean these water bodies, providing an environmental benefit before the filament even reaches the printer. It is biodegradable, durable, and suitable for a wide range of printing applications, further enhancing its sustainability.

Fused Deposition Modeling FDM with Recycled Materials

FDM technology, which melts and extrudes thermoplastic filaments to form an object layer by layer, can utilize recycled plastics. These can range from recycled PLA to ABS and PETG, turning plastic waste into valuable 3D printed objects. This approach greatly reduces the carbon footprint associated with manufacturing new plastic filaments.

PLA Blends with Natural Fibers

There are PLA filaments available that are blended with natural fibers such as bamboo, hemp, or flax. These blends not only reduce the use of pure plastics but also enhance the biodegradability and mechanical properties of the prints. The natural fibers bring additional sustainability to the PLA, making it even more environmentally friendly.

Mushroom Mycelium

Mushroom mycelium is a newer, experimental material in the 3D printing world, which utilizes the root structure of mushrooms. This organic material can be grown in molds to form packaging, insulation, and even structural elements. While the technology for 3D printing with mycelium is still being perfected, its potential for sustainable manufacturing is immense.

Biopolymer Alloys

Biopolymer alloys are combinations of different biodegradable materials designed to enhance certain properties, such as strength, flexibility, or heat resistance. By mixing materials such as PLA with other biopolymers, manufacturers can create filaments that are not only more versatile in their application but are also more sustainable than their pure counterparts.

Reclaimed Wood Filament

Similar to wood filaments, reclaimed wood filament takes sustainability a step further by using wood waste from sawmills, woodworking shops, and other industries. This not only prevents the wood waste from ending up in landfills but also gives it a new life as a 3D printed object, promoting a circular economy.

PHA Polyhydroxyalkanoates

PHA filaments are made from polyhydroxyalkanoates, a type of polyester produced by microorganisms. PHA is biodegradable and can be produced through the bacterial fermentation of sugars or lipids. As a 3D printing material, PHA offers an exciting sustainable alternative due to its natural origin and the ecological production process, which can make use of waste products as feedstock.
