INNOVATION | 3D PRINTING
Above: BASF 3D Printing Solutions has a range of materials for 3D printing applications
ment aims to introduce next-generation Victrex PAEK polymers and composites while improving the performance of the underlying processes. Investment in the new equipment, and its commis- sioning, are expected to accelerate the commer- cialisation of materials for high-performance parts. The Centre for Additive Layer Manufacturing at Exeter is one of the first to commission the recently launched equipment. The new EOS P 810 is capable of printing with
materials that have melting temperatures around 300°C and is particularly suitable for the new low-melting-point PAEK polymers, designed and optimised by Victrex specifically for additive manufacturing. The work invested in this produc- tion-ready machine, which has a build volume of 700 × 380 × 380mm and two 70W lasers, is aimed at ensuring that future demand for large-scale parts will be readily met by the market as the platform is rolled out across the supply chain.
Advanced polymers Arkema is accelerating development of its ad- vanced polymers and liquid resins for additive manufacturing of high-tech parts. The group has expanded its list of industrial partnerships and collaborative research programmes all along the supply chain. For example, N3xtDimension liquid resins are solutions for UV curable 3D printing with engineered resins and custom liquid resin systems. There are three new resins: high-temperature- resistant resin N3D T-1105; low-viscosity casting resin N3D C-1115; and impact modifier resin PRO22362. Arkema, which already offers thermo- plastic polymer powders — Rilsan polyamide 11 fine powder, Orgasol invent smooth powders, and Kepstan PEKK — is enhancing its range with the development of SLS PEBAX powder. This partially bio-based thermoplastic elastomer for SLS pro- vides a combination of the usual strength of

polyamides plus the flexibility and elasticity of polyethers/polyesters, which is ideal for sports applications. Arkema is further supplementing its range of advanced polymers for filament extrusion printing technologies with MMA resin-based filaments offering good mechanical properties, UV resistance and optical performance. Arkema is also enhancing strategic partnerships, such as with Kimya. Launched in 2018, the partner- ship with Armor 3D, part of Kimya Lab, has enabled the development of a new Kepstan PEKK-based filament. Another new filament, PEBA-S Kimya, which is made from PEBAX elastomer, has been developed for applications requiring lightness, good energy return and resistance to low tempera- tures, such as in the sports sector. In other partnerships, Stratasys has launched
Antero 840CN03, a new PEKK-based polymer leveraging Arkema’s Kepstan PEKK technology. The new Antero material, with consistent electrostatic discharge performance, is ideal for printing high temperature and chemical-resistant parts, particu- larly for aerospace and industrial applications. Following the successful introduction of Rilsan PA11 in Autodesk’s Fusion 360 earlier this year, Arkema and Autodesk will further expand this collaboration to include Arkema’s speciality Orgasol PA12 powders. This will allow Fusion 360 customers to generative design outcomes that are ready to print based upon PA12 powder print profiles.
BASF 3D Printing Solutions has introduced its
new Forward AM corporate brand. The company’s range incorporates the complete virtual engineer- ing service spectrum, from a component’s initial design concept, through simulation including printing and finishing, to scanning and testing. The portfolio will also be complemented by an ad- vanced flexible coating. This is claimed to be well suited to flexible materials such as elastic Ultrasint TPU 01, developed in collaboration with HP for its Jet Fusion 3D-printer. The new coating can be used in special applications and will be available from Forward AM in black, white, metallic silver, and transparent. Forward AM is also set to expand its thermoplastic Ultrafuse filament portfolio signifi- cantly, starting with the test-marketing of Ultrafuse TPU 95A, Ultrafuse ABS ESD and Ultrafuse PEI 9085. In addition, engine brackets have been developed in collaboration with Daimler and there is particular interest in the automotive industry, where Ultrasint PA6 MF material is providing extreme rigidity and robustness, as well as good printability on Farsoon high temperature printers. Solvay has added Solef PVDF AM filament to its
