PETG - grey - Fillament for 3D-Printers PETG (Polyethylene Terephthalate Glycol) is a filament material that combines the strength and durability of ABS with the easy printability of PLA. It is known for its high impact resistance, good flexibility, and resistance to chemicals and moisture, making it ideal for functional parts and outdoor use. PETG has a higher melting temperature than PLA and often requires a heated print bed to avoid warping. Additionally, the material is relatively easy to print with, while providing smooth and strong printed surfaces. Weight: 1 kg. Diameter: 1,75 ± 0,05 mm. Melting temperature: 220 - 260 °C. Melting temperature refers to the temperature at which a filament material for a 3D printer starts to melt and becomes fluid enough to be extruded through the printer's nozzle. It is a critical parameter as the correct melting temperature ensures a stable flow rate and good adhesion between the printed layers. Too low a temperature can result in under-extrusion and weak print quality, while too high a temperature can cause over-melting, leading to poor detail and material degradation. Impact strength: 8,7 KJ/m². Impact Strength (KJ/m²) indicates how much energy a material can absorb upon impact before breaking. For 3D printer filaments, it shows how resistant the material is to shocks. A higher value means the material is more robust and can withstand greater impacts without breaking. Tensile strength: 20 %. Tensile strength (%) indicates how much a material can stretch or deform before it breaks. For 3D printer filament, it means how much a printed item can bend or stretch before it fails. This is an important property as it shows how flexible or brittle the printed object will be. A higher percentage of tensile break means the material can stretch more, making it more flexible and less likely to break under stress. Temperature resistance: 60 - 80 °C. before deformation Temperature resistance indicates how much heat a filament can withstand before it starts to lose its shape and deform. For 3D printer filament, this means how stable the printed object will be when exposed to heat. This is important when using printed parts in warm environments, as high temperature resistance ensures that the print maintains its shape and function under stress. Yield Strength at 50 mm/min: : 50 MPa (3D printing) Yield Strength at 50 mm/min indicates the stress a material can withstand while being stretched at a rate of 50 mm/min before it starts to deform permanently. It shows how strong a printed object is before it loses its shape and sustains permanent damage. This property is important for understanding how durable a print will be under stress. Melt flow index: 20. Melt Flow Index (MFI) indicates how easily a thermoplastic material flows when melted. It describes how quickly the material can be extruded from a 3D printer nozzle under specific conditions. A higher Melt Flow Index means the material flows more easily, which can be
