What is Polyethylene Terephthalate Glycol (PETG) used for?

PETG is an adaptation of PET (polyethylene terephthalate) where ‘G’ is glycol, which is added at a molecular level to develop different chemical properties. PET uses the same monomers as glycol-modified PETG. Still, the difference is that the best PETG filament has greater durability and strength, more impact resistance, and is ideal for higher temperatures. It is a thermoplastic polyester. What is PETG so popular for? Here as follows;

  • It is applicable in various industries because it is resistant to heat, solvents, and impacts. Therefore, it is mostly used for packaging, electronic insulators, retail stands and displays, signage, and advertising displays. 
  • It is widely used in 3D printing technology because the ‘G’ glycol prevents all PET problems, including cloudiness and fragility, overheating, etc. Good adhesion between layers will reduce 
  • The possibilities of deformation during printing, 
  • Good resistance in a low-temperature environment, 
  • Chemical resistance against acids and bases, 
  • And finally, the absence of odor during printing makes it perfect for home and office use. 
  • Polyethylene terephthalate glycol is ideal for creating flexible parts with good resistance to shock, like pressure-clad items, protective parts, or even food containers. It is fully recyclable, which minimizes waste and the potential negative environmental impact. 

Polyethylene terephthalate glycol is a perfectly used and versatile plastic with several properties that are better than any other material. With a maximizing uptake in 3D printing technology and application, PETG is becoming popular.

Apart from PETG filament, Snapmaker offers 3D printing materials like PLA and more. PLA filament is quite acceptable in the additive manufacturing industry partly because it is made from renewable products and has mechanical properties. But what are the other reasons why it is considered the best? Here are the reasons:

  • It is considered a semi-crystalline polymer with a melting temperature of 180 degrees Celsius, lower than ABS filament.
  • PLA has great resistance to heat, making it often used in the food industry.
  • When printing with PLA, it does not require complex post-processing. On the other hand, when using supports, it will be easily removed.
  • Making a foundation or first layer with PLA is tricky. Still, Snapmaker’s 3D printer, which comes with an adhesive printing tray, facilitates the detachment once the piece is finished, producing a smooth and high-quality printout. 

Polylactic acid (PLA) was invented in the 1930s by the American chemist known as Wallace Carothers. PLA is a thermoplastic designed from renewable resources like corn starch, sugarcane, or tapioca roots; this filament is far better than other materials made from petroleum. Because of its ecological nature, it has become popular within the 3D printing industry, making it easily available even in small spools like 1kg PLA filament. 

How is this filament produced? The thermoplastic polymer is produced by fermenting a carbohydrate source such as corn starch. Here, the natural product is ground to separate the starch from the corn and then mixed with acid or lactic monomers. This mixture breaks the starch into dextrose (D-glucose) or corn sugar. Finally, glucose fermentation releases L-lactic acid, the basic component of the best PLA filament. It is considered a non-Newtonian pseudoplastic fluid, that is, its viscosity will change depending on the stress subjected to it. It is the finest cut material with viscosity reduced as you apply stress.
