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. PMMA (polymethyl methacrylate) is a water-clear material compared to PETG. Its most outstanding properties are its high thermal resistance and, worth mentioning, its good impact resistance. PMMA is also used in industry, and is widely used in dental technology. This material is compatible with the human body and can be considered as a tissue substitute. It is also used in many other industries, such as the automotive and construction industries. In addition to its tissue-friendly properties, it is also highly UV-resistant and polishable (which is one of the reasons why it is used in dentistry). It is also robust and scratch-resistant, and is weather-resistant, with excellent optical properties. It is available in two filament diameters, 1.75mm and 2.85mm, in transparent colours. 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.
