Spectrum 3D filament, S-Flex 85A, 1,75mm, 250g, 80570, pacific blue

Flexibility with very good impact toughness and thermal insulation Spectrum S-Flex 85A is a filament based on thermoplastic polyether polyurethane. In the field of additive manufacturing, S-Flex 85A is a material characterized by a relatively easy and trouble-free 3D printing process. Another advantage that enables a perfect print is very good adhesion of the first layer of the printed part to the build surface, regardless of whether it is made of glass, steel, plastic, or other material. Low processing shrinkage and high flexibility significantly reduce the risk of so-called edge warping of manufactured parts. The distinguishing feature in the filament name 85A refers to the hardness of the material on the Shore scale and classifies Spectrum S-Flex 85A in the category of hard elastomers. This property reduces the risk of filament deformation in the feed system leading the material to the print head during 3D printing. This allows slightly faster printing compared to other, more compliant elastomers.

Parts made from Spectrum S-Flex 85A are characterized by very high resistance to hydrolysis (a type of degradation caused by the presence of water), good recyclability, and very good resistance to dynamic forces. Thanks to these properties, it is possible to print 3D parts that protect surfaces exposed to impact (bumpers, sharp edge protectors), sealing and protective elements with high chemical resistance, as well as thermal insulators.

Key properties: high resistance to hydrolysis up to 650% elongation at break Shore-A hardness 85 high resistance to tearing and tension low shrinkage resistance to many common industrial oils and chemicals reduced stringing while the printer is idle

Applications: production of seals with high chemical resistance production of objects that must be used as energy absorbers functional parts all types of bumpers, vibration dampers protective housings snap-fit parts sleeves hinges bumpers and flexible spacers sealing parts with increased stiffness spring damping elements for use in machinery manufacturing and modeling flexible belts with high strength covers and housings for various devices

Filament specifications: filament diameter: 1.75mm / 2.85mm extrusion temperature: 200-230"C bed temperature: 50-70"C printing speed: 20-70mm/s
