巴西石化公司Braskem已经发布了其第一线可持续3D打印丝。
Made up of three filaments produced from bio-based ethylene vinyl acetate (EVA), recycled polyethylene (PE) and polypropylene (PP), the new range will be showcased at the upcomingRAPID + TCT底特律的贸易展览会。
“巴西长期以来创新的历史和producing more sustainable bio-based polymer 3D printing filaments reaffirms our commitment to a more circular, carbon neutral future,” said Jason Vagnozzi, Braskem’s Global Commercial Director of Additive Manufacturing.
“We couldn’t be more excited to present these newest additions to our 3D printing product portfolio at the RAPID + TCT 2022 conference as our clients seek more sustainability solutions for the future.”
Braskem’s growing AM materials portfolio
Since its founding in 2002, Braskem has been developing plastics for new applications, particularly within the aerospace sector. The firm has worked with various well-known names in the field, such asRedwire- 拥有Made in Space和NASA开发一个塑料回收设施为了International Space Station.
The company later expanded its Innovation & Technology (I&T) center in Pennsylvania to include a dedicated 2,800 square meter lab for additive manufacturing, and soon after launched its first PP material in partnership withEOS Groupsubsidiary高级激光材料.
2020年5月，布拉斯姆（Braskem）推出了自己的portfolio of 3D printing materialscomprised of PP-based filament, powder, and pellets. A couple of months afterward, the firm announced a partnership with 3D printer manufacturer and service provider泰坦机器人技术to launch anew PP resinspecifically engineered for Titan’sAtlas line of dual extrusion printers.
Since then, Braskem hascontinued to expand its I&T center重点是解决其碳中性和创新目标，去年entered into a distribution agreement与热塑性树脂分配器Nexeo Plasticsthat saw the firm’s PP filament become available through 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 more eco-friendly alternative to traditional flexible materials currently on the market. Marketed as a “low carbon footprint formulation”, the filament is engineered to offer a combination of flexibility, ductility, lightweighting, and moisture resistant properties for direct drive 3D printing systems.
FL600EVA-BIO reportedly offers an excellent surface finish, low warpage, and high dimensional stability to parts. Featuring superb bed adhesion, the filament does not require a heated chamber or need to undergo a drying process. Regarding applications, the filament is suitable for the rapid prototyping and mass customization of flexible and lightweight parts within the packaging, industrial, fashion, and consumer sectors.
The second filament in Braskem’s new sustainable materials line is FL600R, a recycled polyolefin filament designed for use in extrusion-based 3D printing systems. Primarily sourced from recycled bottle caps (around 90 percent) the filament is a PE-PP blend that aims to provide a more sustainable filament option without compromising printability.
根据Braskem的说法，该材料提供的低密度和水，化学和抗冲击力与原始PE和基于PP的材料相同。FL600R提供黑色可供选择，可用于汽车，包装，消费者和工业市场中的应用，并适合快速原型和大规模定制过程。灯丝与类似的3D打印系统兼容Ultimaker,Creality, and other similar machine manufacturers, and has print profiles available on Ultimaker’s Cura Marketplace.
Rounding off Braskem’s new line of sustainable filaments is FL605R-CF, an engineering-grade polymer containing recycled carbon fiber for added strength and durability. Also containing 90 percent recycled content sourced from bottle caps, the filament offers many of the benefits of FL600R but with the added mechanical properties of carbon fiber.
因此，FL605R-CF适用于航空航天应用，提供高强度，刚度和低密度，以实现轻质和刚性的零件设计。像FL600R一样，灯丝也适用于汽车，包装，消费者和工业应用，并且与Ultimaker和Creality Systems兼容。
Braskem将在2022年5月17日至9日举行的Rapid + TCT展示其新的可持续灯丝范围。3D印刷行业将报告底特律的所有新闻，因此请务必打个招呼和get in touch分享您的更新。
Improving material sustainability
With an增加对圆形的关注，可持续性，以及waste reductionwithin the manufacturing sector, numerous 3D printing firms are looking to develop ever-more sustainable materials for additive manufacturing.
For instance,回流has launched a range ofeco-friendly ‘Seaglass’ materials由本地采购的塑料制成Recreusunveiled a TPU filament that is完全从废物鞋类中回收材料。别处，Fillamentumhas debuted its 100 percentbiodegradable NonOilen filamentat various trade shows and researchers fromRMIT University已经开发了自己的环保3D可打印混凝土containing recycled glass.
In recent years, various projects have also explored new由食物浪费制成的3D可打印材料, such askombucha tea,pasta和橙皮, as well as more niche waste streams likeplant cell walls和termite insect refuse.
