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. The best-known filament material on the market today is PLA (polylactic acid). It is often based on corn starch, so it can be said to be a plant-based plastic. PLA is a relatively low temperature plasticiser compared to other materials. A big advantage is that it is very easy to print. In most cases, the material does not clog the nozzle. The other factor is that it is affordable and ranges in value. It is also worth bearing in mind that PLA should not be used for products that are to be exposed to heat, as it can distort or melt. ABS or PETG are more durable materials than PLA and can be more fragile than other materials, so it is worth considering this when choosing a material. It is most often suitable for aesthetic use, but not for mechanical applications. 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.
