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. After PLA, one of the most popular filament materials used is ABS (acrylonitrile butadiene styrene). Not only is it used in 3D printing, but it is also used for ABS injection moulding and machining. Its biggest advantage over PLA is that it is strong and extremely durable. Compared to PLA, it requires a much higher temperature to melt the material and therefore requires a heated tray for printing. It also has good impact resistance and good heat resistance. It is worth using for printing objects that are used on a daily basis, as it will warp or bend faster than it will break. ABS is a particularly heat-sensitive material. It can crack when exposed to changing temperatures and is also sensitive to UV light. If exposed to too much UV light, the material becomes brittle. Outdoor use is less recommended. The filament in our webshop is made by the European manufacturer Herz-FILAMENT Hungary. High quality filaments are also suitable for industrial applications. In 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.
