Spectrum S-Flex 85A 1.75mm BAHAMA YELLOW (RAL 1018) 0,25kg

Flexibility with excellent impact resistance and thermal insulation

Spectrum S-Flex 85A is a thermoplastic polyether polyurethane-based filament. In the context of additive manufacturing, S-Flex 85A is a material characterized by a relatively easy and error-free 3D printing process. An additional advantage that enables perfect printing is the excellent adhesion of the first layer of the printed part to the workspace, regardless of whether it is made of glass, steel, plastic or other material.

The low processing shrinkage and high flexibility significantly reduce the risk of so-called edge curling of produced parts. The distinguishing feature of the 85A filament name 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, from the perspective of the 3D printing process, reduces the risk of filament deformation in the insertion system that brings the material to the print head. This allows for slightly faster printing than other more compact elastomers.

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

VERIFY YOUR SPOOL – the most precise quality control system on  the market
Filament for 3D printers is manufactured by the method of free extrusion, which is one of the most difficult processing techniques by extrusion, due to the particularly significant impact of process parameters on product dimensions and material homogenization.

During the production each 1mm of Spectrum Filament is being continuously measured in 2 axes with ±0.8µm accuracy, which allow obtaining a high-quality final product. To prove this, Spectrum Filaments, as one of the few manufacturers in the world, has introduced the possibility of online presentation, individually for each manufactured spool:

• the course of diameter on the entire length of the spool,
• mean diameter,
• ovality,
• standard deviation.

Precise survey guarantees that Spectrum Filaments products meet rigorous market requirements.
