Filamento Spectrum ASA Kevlar 1.75mm NOIR 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 aim 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, which is 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, primarily known as Kevlar, are used to make items highly resistant to damage such as bulletproof vests, helmets and speaker membranes. Aramid fibres do not fracture easily under stress (unlike glass and carbon fibres), but undergo shear and tear fractures, which gives them high damage resistance.

Aramid itself is not a particularly UV-resistant material, the coating and, in a sense, the protection in the ASA polymer, which is highly resistant to this factor, ensure a long life for the fibres and the entire composite. Unlike carbon and glass fibres, Kevlar fibres exhibit significantly less printer nozzle abrasion, which is not insignificant for print 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 way into 3D printing technology. Components printed from Spectrum ASA Kevlar can be used in applications requiring sunlight resistance and high impact resistance (e.g. bumpers, protection, etc.). The aramid fibre makes the outer surface of the prints rougher, making them more matte and, therefore, more aesthetically pleasing than classic ASA.

Key features:

• Reinforced with aramid fibres
• Thermal resistance HDT - 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 heated chamber
• matte print surface
• perfect layer adhesion

Applications:

• functional prototype,
• production tools
• manufacturing of fixtures and assembly tools

Packaging:

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