Filamento Spectrum ASA Kevlar 1.75mm NATUREL 0.75kg

High durability in production applications

Spectrum ASA Kevlar filament is a technical composite material based on a combination of ASA copolymer and aramid fibres. The goal of producing composite materials by combining different types of materials is to impart new properties, previously unattainable for separate components. As a basis for the composite, we used ASA copolymer, known for its high resistance to weathering conditions, combining it with aramid, which is used to make some of the strongest synthetic fibres.

Aramid fibres, mainly known as Kevlar, are used to make items highly resistant to damage such as bulletproof vests, helmets, and loudspeaker membranes. Aramid fibres do not fracture easily under stress (unlike glass and carbon fibres), but undergo shear fracture and tear, which gives them high damage resistance.

Aramid itself is not a material that is particularly resistant to UV radiation, the casing, and in a sense, the protection in the ASA polymer, which is highly resistant to this factor, ensures a long service life for the fibres and the entire composite. Unlike carbon and glass fibres, Kevlar fibres show significantly less printer nozzle abrasion, which is not insignificant for the printing processing costs. The use of fibre structures helps to reduce material shrinkage during printing, making it possible to produce large-scale models.

With our new filament, Kevlar is now also finding its place in 3D printing technology. Components printed from Spectrum ASA Kevlar can be used in applications requiring sunlight resistance and high impact strength (e.g. bumpers, protection, etc.). The aramid fibre makes the outer surface of prints rougher, making them more matte and, therefore, more aesthetically pleasing than classic ASA.

Key features:

• Reinforced with aramid fibres
• HDT thermal resistance - 89°C
• Vicat softening point - 94°C
• good aging resistance
• very strong impact resistance
• relatively high chemical resistance
• UV resistance
• printable on desktop devices without a heated chamber
• matte print surface
• perfect layer adhesion

Applications:

• functional prototypes,
• production tools
• manufacturing of fixtures and assembly tools
• manufacturing of components exposed to impacts
• components that require high resistance to outdoor exposure

Packaging

The filament is wound on a neat, transparent spool. Each spool contains information on the material type, diameter and recommended printing temperature. The filament is vacuum-packed with a moisture absorber. The entire product is packed in original film-coated Spectrum Filaments packaging.
