PETG (Polyethylene Terephthalate Glycol-Modified) is a high quality thermoplastic filament used for 3D printing. This material combines some of the best features of PLA and ABS, offering precision, strength and durability. Here is a detailed description of PETG filament for 3D printing:
Properties and characteristics:
Strength and Durability: PETG filament is known for its exceptional strength and impact resistance. It is more flexible than ABS and PLA, making it suitable for making parts that need to withstand loads and impacts.
Heat resistance: PETG can withstand higher temperatures than PLA, but not as high as ABS. This makes it suitable for applications that require heat resistance, but not at temperatures as high as those required by ABS.
Transparency and light transmission: With the right settings, PETG filament can offer a certain degree of transparency, making it suitable for making light transparent models or accessories.
Biodegradability: Although PETG is not a completely biodegradable material, its biodegradability is better than ABS, making it more environmentally acceptable.
Applications: PETG filament is suitable for various applications:
Prototyping: Because of its strength and durability, PETG is used to make functional prototypes and models.
Accessories and Homeware: PETG is used to make a variety of accessories such as mobile phone holders, mugs, vases, etc.
Cosmetic or light transparent patterns: Because of its slight transparency, PETG is used to create light or cosmetic patterns.
Technical features: PETG filament is relatively easy to print, but requires more careful settings compared to PLA. The recommended extrusion temperature for PETG filament usually ranges from 230°C to 250°C. It is printed on a heated printing platform or on an adhesive base to prevent deformation of the model during printing. Also, it is less prone to bulges and defects than ABS, making it easier to print.
