The 3D printing sector is booming. Since the early 2000s, the evolution of this technology has seen the market rapidly democratize.
Initially confined to prototyping and small parts, 3D printing is now used in many sectors, including the automotive, medical, luxury and even construction industries for large-scale objects.
One of the most widely used materials is PLA (polylactic acid). It is easy to process thanks to its low transformation temperature, and gives a good aesthetic quality to the part.
ADVANTAGES
- Compatible with existing processes
- Easy to install
- Mostly biobased
- Biodegradability depending on application
- Potential improvement in environmental footprint
- Unique design incorporating by-products
In addition to PLA, other bioplastics such as biobased polyesters and biocomposites enriched with natural fibers or by-products (coffee, cereals, shellfish, etc.) open up prospects for diversifying applications and responding to specific constraints, while at the same time creating textural effects and designs specific to each formulation.
In 3D printing, PHAs (polyhydroxyalkanoates), derived from bacterial fermentation, stand out for their good thermal stability, excellent adhesion between layers and biodegradability in a wide range of media. Ideal for prototypes or finished products, they can be used to create both flexible and rigid materials, depending on the desired application.
