Filament or plastic filament is used as a raw material in 3D printing. The filament can have different textures and colours. Today they are available in an amazing variety of colours and shades. Filaments are sold in rolls. Some material types and colours are available in 3kg packs, but the most common is the 1kg roll size. The plastic filament is melted by the 3D printer at a high temperature and the nozzle is used to continuously layer the melted filament onto the printer table. This is how the model you want to print is formed and shaped. The filaments are available in two sizes in diameter, 1.75mm and 2.85mm. ASA (acrylic styrene acrylonitrile) filament material has properties that approach those of the popular ABS material. ASA was developed specifically for 3D printing and its properties reflect this. It is a strong and robust material with outstanding impact and scratch resistance. Compared to ABS, ASA is insensitive to UV light and is well suited for outdoor use. It also adapts well to changes in weather conditions and is more resistant to high temperatures than ABS. In addition, it is less prone to fibrillation. Care should be taken not to cool it too much during printing, but it is worth ventilating it during the process, as the molten material can have an irritating or unpleasant smell. It is available in our webshop in natural colour, in two filament diameter sizes. The filaments in our webshop are made by the European manufacturer Herz-FILAMENT Hungary. High quality filaments are also suitable for industrial applications. During the production of filament, care is taken to work only with pure materials. They are produced under quality control. After purchasing the filament, keep it in a cool, dry, dark place as recommended by the manufacturer. Once opened, it is recommended that you use the product within 12 months, as after this time the plastic material may lose its elasticity and other properties.
