TECHNOLOGY | 3D PRINT COMPOUNDS
in 3D printing with the acquisition of Colorado Photopolymer Solutions. The company, which is based at Boulder, Colorado, US, specialises in photopolymer formulation for 3D printing in areas such as medical, composites, construction and consumer goods sectors. Arkema has also strengthened its partnership
with Continuous Composites, creator of the Continuous Fiber 3D Printing technology (CF3D). This US-based start-up aims to advance develop- ment of 3D composite manufacturing technologies for production of lightweight structures and offers a complete solution that includes software, hardware, material and motion platforms. Through its Sartomer Business Line, Arkema is developing a new generation of solutions for the CF3D process. Following the signing of a Joint Development Agreement in 2019, the two companies say they have hit some key milestones with the develop- ment of N3xtDimension photocurable resins for the process.
Adaptive3D is another US start-up that Arkema has invested in. The company sells photopolymer resins to enable additive manufacturing of tough, strain-tolerant, tear-resistant rubbers. Adaptive3D printable photo-resins are optimised for high- throughput manufacturing of functional complex three-dimensional plastic and rubber parts in a wide range of applications in the consumer goods, healthcare, industrial, transportation and oil and gas markets. A collaboration between Henkel and Carbon aims to develop and validate the former’s Loctite-branded formulations for use with Carbon’s additive manufacturing process. As part of the collaboration, the newly introduced Loctite 3D IND405 Clear material is immediately available to Carbon customers. The partnership agreement allows industrial customers to access Henkel’s single-component (1K) technologies for use with the Carbon Digital Light Synthesis (Carbon DLS) 3D printing process. The Loctite 3D
IND405 Clear grade certified for Carbon printers is a clear, tough, semi-rigid, 3D printable material. The one-part liquid is said to be easily printed and is suitable for applications including enclosures and housings, light pipe prototypes, bottle prototypes, and jigs and fixtures. Henkel is also working with Nexa3D, which
makes production photopolymer-based 3D printers, and has developed three new functional polymers for durable prototype, production tooling and functional end-use parts with extended UV weathering stability. The partnership aims to move additive manufacturing towards mass production of functional parts across multiple industries using Nexa3D’s NXE 400 manufacturing process. The new photopolymer materials include xPP405-Black, which is a tough semi-rigid high- strength plastic resin providing a modulus similar to PP, 130% tensile elongation at failure and good UV weathering stability as characterised by ASTM G154 testing. xPP405-Black has an industrial black finish and is suitable for production of end-use parts such as piping, large housings and enclo- sures. The xPP405-Clear grade combines clarity, toughness and impact strength with a heat
deflection temperature between 50-60℃. It can be finished for clarity and is suitable for production of packaging, light guides and luminaire compo- nents, and micro-fluidics. The xPEEK147-Black grade is a tough material with good surface finish and dimensional stability and a high heat deflection temperature. It is suitable for production of tooling and func- tional end-use parts for automotive under- the-hood applications. xPEEK147 provides a temperature resistance of up to 230°C togeth- er with high stiffness and dimensional stability, long term thermal stability, and good solvent resistance.
