47 CompositesWorld.com New Products » ADDITIVE MANUFACTURING EQUIPMENT & MATERIALS 3D printing factory floor solutions Stratasys (Minneapolis, MN, US, and Rehovot, Israel) has unveiled a range of new solu- tions designed to accelerate the use of additive manufacturing in factory environments. Announcements made at RAPID+TCT 2018 in April showcased 3D printers compatible with carbon fiber composite materials, including the new F900 Production 3D Printer, a third- generation version of the company's flagship Fortus 900mc fused deposition modeling (FDM) system. Features include an MTConnect-ready interface with production-ready accuracy and repeatability. The F900 is available in three solu- tions: the F900, the F900 AICS (Aircraft Interiors Certification Solution) and the F900 PRO. The latter two extend the platform into specialized products to meet the unique needs: The AICS is reportedly a first-of-its-kind solution that delivers the performance and traceability required for flight-worthy parts. The F900 PRO, described as a production-grade system, is said to produce parts with the highest FDM repeatability and performance, using ULTEM 9085 resin, and is designed to deliver AICS-equivalent repeatability to all target industries for final part reproduction. The company notes that owners of existing Fortus 900mc systems may upgrade to any of the three current F900 systems. Also new: In addition to offering its carbon fiber-reinforced FDM resin, Carbon Fiber Nylon 12 (12CF), on its Fortus 900 and 450 systems, Stratasys' manufacturing services division, Stratasys Direct Manufacturing, now offers parts built with FDM Nylon 12CF, ideal for functional prototypes and production parts in high-requirement applications. Stratasys also now offers this material on a specialized Fortus 380 and has a family of 3D printers in a range of price points that can build with Nylon 12CF. At CW press time, Stratasys expected the first Fortus 380 CF to ship in by third quarter 2018. stratasys.com | stratasysdirect.com » POLYMER RESIN ADDITIVES & MODIFIERS Hollow microspheres for SMCs 3M (St. Paul, MN, US) introduced in May its hollow microsphere product, Glass Bubbles S32HS, for use in lightweight sheet molded compound (SMC) products. The microspheres, made from water-resistant and chemically-stable soda-lime borosilicate glass, are designed to help OEMs achieve up to a 40% weight reduction in composite parts, at a density below 1.0 g/cc, while still enabling a class A paintable finish. The company says the product not only reduces weight compared to conventional fillers but also functions to damp noise, vibration and harmonics and reduce thermal expansion, making SMCs an attractive option in automotive design. The microspheres, according to 3M, average 25 microns in size, resist softening at temperatures below 600°C, and have a crush strength of 6,000 psi (90% survival by volume). 3m.com/us/auto_marine_aero/index.html | coremt.com » ADDITIVE MANUFACTURING EQUIPMENT & MATERIALS New filaments for fused deposition modeling SABIC (Pittsfield, MA, US) has three new filaments for fused deposition modeling: ULTEM AM1010F filament for general high-temperature applica- tions, including tooling; and ULTEM AMHU1010F and LEXAN AMHC620F filaments for healthcare applications. The two filaments are made with SABIC healthcare-grade resins, which are included in the SABIC's Healthcare Product Policy and offer traceability. The policy provides pre-assessment of resin bio-compatibility, according to ISO 10993 or USP Class VI standards, and FDA Drug or Device Master File listings. According to SABIC, new healthcare application development can become more efficient by using these filaments in prototypes, because the same base resin materials are available in injection molding grades for production. The ULTEM AMHU1010F filament, an unpigmented polyetherimide (PEI) product, provides inherent resistance to high heat. Printed parts can be sterilized using gamma radiation or ethylene oxide (EtO) or via steam autoclave. It provides resistance to high heat (a T g of 217°C) and high mechanical strength, and can be used in applications such as short-cycle injection molding tools, carbon fiber layup tools and automotive components. The filament is UL94 V-0 compliant at 1.5 mm and 5VA compliant at 3.0 mm. The LEXAN AMHC620F polycar- bonate (PC) filament, available in white, is also bio-compatible and can be sterilized with gamma or EtO methods. This filament meets UL94 HB rating at 1.5mm. According to SABIC, both are suitable for a variety of medical devices, from conceptual modeling to functional prototyping and end-use parts that include surgical instru- ments, single-use devices and casts/ splints. sabic-ip.com NEW PRODUCTS
