Filament PETG

PETG filament: The robust choice for versatile 3D printing

PETG (polyethylene terephthalate glycol) is a popular filament material for 3D printing. It is a variant of PET (polyethylene terephthalate) that has been modified with glycol to improve printability and impact resistance. PETG offers a combination of mechanical strength, durability and optical clarity and is versatile in a variety of applications.



Here is some important information about PETG filament:

1. Printing Properties : PETG is a bit more difficult to print compared to PLA or ABS. It requires a higher print temperature, typically between 220°C and 250°C, and a heated build plate to minimize warping. However, PETG has a lower tendency to deform than ABS and offers good layer adhesion.

2. Strength and Durability : PETG filament creates objects with high strength and impact resistance. It is more resistant to external influences such as shock loads and offers better resistance to chemical substances than PLA. PETG printed objects are flexible and have some elasticity.

3. Transparent and Clear : PETG offers good optical clarity and transparency. It is less prone to yellowing compared to PLA, making it well suited for printing transparent or translucent objects.

4. Food grade : PETG is food grade and safe for food contact. It is widely used in the manufacture of containers, bottles or other items that come into contact with food.

5. Applications : PETG is versatile and has applications in various areas. It is widely used for functional prototypes, mechanical parts, casings, electronic device cases, toys, bottles, packaging and displays.

It is important to note that PETG requires a higher printing temperature and is different from PLA or ABS. A good print setting and a suitable printing environment are required to achieve optimal results.

Here are ten examples of PETG filament applications:

  1. Functional Prototypes : PETG is well suited for 3D printing functional prototypes of mechanical parts due to its strength and durability.

  2. Housings and Components for Electronic Devices : PETG can be used to manufacture housings, brackets and components for electronic devices such as speakers, cameras or robotics.

  3. Bottles and Containers : PETG is food grade and is used in the manufacture of transparent bottles, containers and packaging as it is chemically resistant and shatterproof.

  4. Displays and Signage : Due to its optical clarity, PETG is widely used in the manufacture of transparent displays, signage and billboards.

  5. Protective covers and safety gear : PETG can be used to make protective covers, visors, goggles or face shields because it is tough and transparent.

  6. Lighting Accessories : PETG can be used to make lampshades, light diffusers or light guide plates to achieve even light distribution.

  7. Toys : PETG is a popular material for 3D printing toys and models due to its durability and impact resistance.

  8. Filament Spools and Storage Solutions : PETG can be used for making filament spools, storage boxes.

  9. Automotive Parts : PETG can be used to manufacture automotive parts such as interior panels, dashboards or door handles as it has good impact strength and chemical resistance.

  10. Medical applications : PETG is also used in the medical industry, for example for the manufacture of medical devices, housings or holders for medical instruments due to its chemical resistance and sterilizability.

These examples show the versatility of PETG filament and its possible uses in different areas. It is a material that is suitable for both functional and aesthetic purposes, offering a good combination of strength, durability and optical clarity.
