PLA high-temperature 3D filament incorporates TotalEnergies Corbion’s Luminy PLA technology into ColorFabb’s existing lightweight PLA filament, with the resulting formulation offering improved temperature and heat resistance while still deliver- ing good 3D printability, low weight and easy processing. In addition, the filament is said to offer an improved carbon footprint when compared to competing filament technologies. The two companies originally developed the
thermomechanical performance. Evonik is also collaborating with industrial 3D print manufacturer Farsoon on a new high-perfor- mance, flexible thermoplastic co-polyester for powder bed fusion 3D printing. This Infinam thermoplastic copolyester (TPC) has been trialed using Farsoon’s powder bed fusion technology at its Americas Demo Center at Austin in Texas, US, and is said to have yielded printed parts with very good tear strength, elongation at break, impact resistance, rebound and elasticity. The material pro- cesses easily on Farsoon equipment while its properties make it suitable for a wide range of automotive, medical, and sporting goods applica- tions, according to Dr Arnim Kraatz, Evonik’s Director of Powder Bed Technologies. Materials supplier TotalEnergies Corbion has been working jointly with thermoplastics filament producer ColorFabb to develop a new generation of lightweight, heat resistant polylactic acid (PLA) filaments for 3D printing. The Light Weight (LW)
material for production of remote-controlled 3D planes that needed to withstand high sun tempera- tures without deforming. However, the Luminy PLA technology is suitable for a broad range of applica- tions where heat resistance is required. It could, for example, be used to print furniture, automotive parts, or components for construction applications. ColorFabb claims the LW-PLA filament is the first to use active foaming technology to achieve light weight, low density PLA parts. The material starts foaming at around 230°C, increasing its volume by nearly three times. During processing, users can choose to decrease material flow by 65% to achieve lightweight parts or use the expansion to reduce print times through larger layer heights or extra thick perimeters. Also new from ColorFabb is allPHA, a 100% biobased plastic 3D printing filament comprised of polyhydroxyalkanoates (PHA). The 100% biode- gradable bioplastic filament is intended for use in projects that require a more sustainable approach. Physical properties include a tensile modulus of 2510MPa, yield strength of 26MPa and tensile strength of 26MPa (ISO 527 testing). The material displays a Charpy notched impact strength of 3.4 kJ/m2
Xtellar – where Braskem meets Taulman3D
Brazilian polyolefin producer Braskem has expanded its additive manufacturing business with the acquisition of Taulman3D, a manufac- turer and distributor of advanced thermoplastics for additive manufac- turing based at Linton in Indiana, US. Taulman3D supplies a range of PA,
recycled PETG, and PET filaments to 3D print operations serving aerospace, automotive, healthcare, and industrial professionals. Its offering includes a 100% recycled 3D print filament. Braskem says the acquisition complements its existing portfolio of

filaments, which includes PE, PP, carbon and glass fibre, and recycled pellet and powder polymers specifi- cally designed for 3D printing applications. It offers grades for several 3D technologies including FFF, SLS and High-Speed Pellet Extrusion. “With projections for the 3D printing industry to grow from $15bn today to $78bn by 2030, growing at an estimated 20% Compound Annual Growth Rate (CAGR), we see en- hanced opportunities to serve this rapidly growing demand,” says Jason
Vagnozzi, Global Commercial Director of Additive Manufacturing at Braskem. Vagnozzi has been named CEO of
Xtellar, a new US-based venture that combines Braskem’s specialty additive manufacturing materials division, which it launched in 2020, with newly acquired of Taulman3D. Xtellar is being launched in collaboration with Oxygea, a corporate capital venture firm focused on sustainable innova- tion and digital transformation. First products and services will be avail- able officially from June 2023. �
