PETG is short for polyurethane terephthalate glycol-modified. It is tough and durable, and it has low shrinkage. It also produces a smoother finish than ABS or PLA filament. It is resistant to chemicals, acid, alkaline, and water, and it is very strong, which makes it ideal for robotics and mechanical parts. This is a very useful filament to use in 3D printing.
Printing with PETG Filament
PETG filament is very popular because it is so strong and durable. However, it is important to follow certain guidelines when you use this material. It has a higher melting point than PLA filament, so you need to make sure that the extruder temperature is set between 210 and 250 degrees Celsius. In addition, the build plate temperature should be set between 80 and 100 degrees Celsius. This is optimal for most PETG printing jobs.
In addition, you should not use a fan for the first two layers, but then turn the full fan on. It will cool the filament that is at the hot end of the nozzle, which will help to prevent stringing and blobbing. You need to make sure that your first layer is good and that the build platform is calibrated correctly. Keep your nozzle clean so that you don’t get chunks of filament stuck together. If you take these precautions, your project will turn out great.
Benefits and Features of PETG Filament
PETG filament is great for a number of different uses, and it offers the following benefits and features:
- Reduced shrinkage
- Resistant to warping
- Higher density
- Great layer adhesion
- No odor during printing
- Resistant to acidic and alkali compounds
- Strong and durable
Uses for PETG Filament
Because PETG filament is strong, flexible, durable, and resistant to impact, it is widely used in many industries. It comes in many translucent colors, and the end result is smooth, glossy, and shatter proof. It can be used to package food and beverages because it is safe and can be sterilized.
In addition, it is commonly used in the medical industry for medical tools, equipment, and prosthesis. As with food and beverages, its ability to be sterilized makes it a favorite in this industry. It is frequently used in retail to produce displays and kiosks, as well. There are many uses for this popular type of filament. It has many great features and a variety of practical uses.
Setting for PETG filament
Hot end: 230-250 C
Heated bed: 70-90 C
