ing traditional supports from the finished part often involves time-consuming processes that can negatively impact productivity and quality. By offering a complementary support material for our Ultem AM9085F filament, SABIC is providing a complete material solution that helps customers save time and effort. Additionally, the ease of support material removal provides part designers greater flexibility in defining print orientation to optimise part performance.” SABIC’s material formulation was developed for use with Ultem AM9085F filament to balance adhesion during printing with the ability to remove the scaffolding easily during post processing. Unlike competitive support materials that often require reheating to facilitate removal, SABIC’s AMS31F filament separates at room temperature. The filament’s white colour also provides a sharp contrast to the amber colour of the Ultem filament, which allows operators to identify the structures to be removed more quickly.

Bioresorbable focus Evonik has launched Resomer filaments for 3D printing of bioresorbable medical implants. A selection of poly(L-lactide) (PLLA), poly (L-lactide- co-glycolide) (PLGA), poly(caprolactone) (PCL) and polydioxanone (PDO) grades are available as standard, with additional customised options available. Mechanical properties such as strength and elongation at break can be tailored to the target application, with bioresorption periods ranging from less than six months to more than three years. “Our new, innovative line of Resomer filaments
provide the flexibility and precision to optimise the 3D printing of medical applications across a range of markets including cranial reconstruction, orthopaedics and dentistry,” says Dr Andreas Karau,
Global Head of Biomaterials for Evonik. “Customers can also leverage the application technology expertise of our Medical Device Competence Center in the US and development labs in Germany and China to optimise product performance and streamline the commercialisation process.” Wacker has developed a new version of its Aceo 3D printing technology for silicone rubber. The new Aceo Imagine Series K2 printer features numerous technical improvements and new software, allowing three-dimensional objects to be reproduced more precisely and with high dimensional accuracy. The addition of multiple printing nozzles means the new printer can process up to four different silicone materials simultaneously, allowing entirely novel designs to be realised (for example, printing in different colours or hardnesses). It also helps in printing of hollow objects, which require support material.
