Braskem launches the first range of sustainable 3D printing filaments

Brazilian petrochemical company Braskem launched its first line of sustainable 3D printing filaments.

Composed of three filaments produced from biobased ethylene-vinyl acetate (EVA), recycled polyethylene (PE) and polypropylene (PP), the new range will be presented at the next show. FAST + TCT trade show in Detroit.

“Braskem has a long history of innovating and producing more sustainable bio-based polymer 3D printing filaments, which reaffirms our commitment to a more circular and carbon-neutral future,” said Jason Vagnozzi, Global Commercial Director of Manufacturing. Braskem’s additive.

“We couldn’t be more excited to showcase these latest additions to our 3D printing product portfolio at RAPID+ TCT 2022, as our customers look to more sustainable solutions for the future.”

Braskem’s Growing Portfolio of AM Materials

Since its creation in 2002, Braskem has been developing plastics for new applications, particularly in the aeronautics sector. The company has worked with various well-known names in the field, such as red cable-belonging Made in space and Nasa develop a plastic recycling plant to international space station.

The company then expanded its Innovation and Technology (I&T) center in Pennsylvania to include a 2,800 square meter lab dedicated to additive manufacturing, and soon after launched its first PP material in partnership with EOS Group subsidiary company Advanced laser materials.

In May 2020, Braskem launched its own portfolio of 3D printing materials consisting of PP-based filaments, powder and pellets. A few months later, the company announced a partnership with a 3D printer manufacturer and service provider Robotic Titan to launch a new PP resin specifically designed for Titan’s range of Atlas dual extrusion printers.

Since then, Braskem has continued to develop its I&T center with a focus on its carbon neutrality and innovation goals, and last year entered into a distribution agreement with a thermoplastic resin distributor. Nexeo Plastics which saw the company’s PP filament become available on Nexeo’s online marketplace.

Braskem’s sustainable filaments

Braskem has now unveiled three new sustainable filaments for the additive manufacturing market.

The first, FL600EVA-BIO, is a bio-based EVA filament derived from raw sugar cane that is designed to provide a greener alternative to traditional flexible materials currently on the market. Marketed as a “low carbon footprint formulation”, the filament is designed to provide a combination of flexibility, ductility, weight reduction and moisture resistance properties for direct drive 3D printing systems.

The FL600EVA-BIO offers excellent surface finish, low warpage and high dimensional stability of parts. Featuring superb bed adhesion, the filament does not require a heated chamber or drying process. As for applications, the filament is suitable for rapid prototyping and mass customization of flexible and lightweight parts in the packaging, industrial, fashion and consumer sectors.

The second filament in Braskem’s new line of sustainable materials is FL600R, a recycled polyolefin filament designed for use in extrusion 3D printing systems. Sourced primarily from recycled bottle caps (around 90%), the filament is a PE-PP blend which aims to provide a more durable filament option without compromising printability.

According to Braskem, the material offers the same low density and resistance to water, chemicals and impact as virgin materials made from PE and PP. Available in black, the FL600R is intended for applications in the automotive, packaging, consumer and industrial markets and is suitable for rapid prototyping and mass customization processes. The filament is compatible with 3D printing systems such as Ultimaker, Crealityand other similar machine manufacturers, and has print profiles available on Ultimaker’s Cura Marketplace.

Braskem’s new line of sustainable filaments is completed with FL605R-CF, an engineering grade polymer containing recycled carbon fiber for added strength and durability. Also containing 90% recycled content from bottle caps, the filament offers many of the benefits of the FL600R but with the added mechanical properties of carbon fiber.

As such, the FL605R-CF is suitable for aerospace applications, offering high strength, stiffness and low density to enable the design of lightweight and rigid parts. Like the FL600R, the filament is also suitable for automotive, packaging, consumer and industrial applications, and is compatible with Ultimaker and Creality systems.

Braskem will be showcasing its new line of sustainable filaments at RAPID+ TCT taking place May 17-19, 2022. The 3D printing industry will be reporting all the news from Detroit, so be sure to say hello and contact us to share your updates.

Improve the durability of materials

With an increased focus on circularity, sustainability, and waste reduction in manufacturing, many 3D printing companies are looking to develop ever more sustainable materials for additive manufacturing.

For example, Refusal launched a range of eco-friendly ‘Seaglass’ materials made from locally sourced plastics while recess unveiled a 100% recycled TPU filament from shoe waste. Somewhere else, Fillamentum launched its 100% biodegradable NonOilen filament at various trade shows and researchers from RMIT University have developed their own eco-responsible 3D printable concrete containing recycled glass.

In recent years, various projects have also explored new 3D printable materials made from food waste, such as kombucha tea, pasta and orange peel, as well as more specialized waste streams like plant cell walls. and termite insect waste.
