![]() ![]() This makes it a popular choice for parts that need to withstand stress or impact, such as mechanical parts or protective components. It's stronger and more durable than PLA, yet not as brittle as ABS. One of the key advantages of PETG is its balance of strength and flexibility. This results in a filament that combines the strength and printability of PLA with the flexibility and durability of ABS, making it an ideal choice for a wide range of 3D printing applications. ![]() Glycol is added to the material composition to prevent crystallization and increase the material's durability. It's a variant of the standard PET (Polyethylene Terephthalate) material, with the 'G' standing for 'Glycol'. ![]() PETG, or Polyethylene Terephthalate Glycol, is a type of filament widely used in 3D printing. This article gives a rundown of the correct PETG print settings for most situations - though different printers have their own unique requirements - in addition to general advice such as print bed preparation. And while many slicers provide default settings for individual materials like PETG, it helps to understand what these PETG print settings are actually doing so that you can carry out fine-tuning to achieve even better prints. With that in mind, it is essential to properly prepare your 3D printer when printing PETG. Furthermore, its excellent bed adhesion can be both a blessing and a curse, with parts sometimes remaining stuck to the print bed after printing. When melted, PETG has a low level of viscosity, which - while great for fast extrusion - can cause issues like oozing and stringing. It’s affordable too: a spool of cheap PETG filament only costs about $5 more per kilogram than PLA from an equivalent filament brand.įinding the perfect PETG print settings can be tricky, however. In filament form, PETG (glycol modified PET) offers some notable advantages over PLA, such as excellent layer adhesion, good impact resistance, and a low level of shrinkage. Found in synthetic textiles, bottles, and packaging, PET has many desirable characteristics, such as strength, transparency, and lightness.īecause of these characteristics and others, PET has become a go-to material in FDM 3D printing. PET or polyethylene terephthalate is one of the world’s most widely used plastics. ![]()
