RS PRO 1.75 mm Grey PLA 3D Printer Filament, 2.3 kg Building objects is easy with this 3D printer filament from RS PRO. You don't need any special skills or tools to use it and the filament is compatible with most desktop fused deposition modelling (FDM) 3D printers. The filament's polylactic acid (PLA) material is made of natural resources, so anything you make is recyclable. It won't give off a strong, unnatural odour when heated either, so you can use it in enclosed spaces without any concerns. This thermoplastic also has good hardness so it will withstand bumps and movement without breaking. Many industries are turning to 3D printing for quick alternatives to traditional manufacturing. You can use this filament for a wide range of applications, such as making décor for your home or small tools for your workshop. It's Restriction of Hazardous Substances (RoHS) compliant, so it contains only minimal levels of any harmful materials. Features and Benefits - Grey colour - Diameter of 1.75 mm - Weight of 2.3 kg
