What Is PETG 3D Printing?
PETG 3D printing is the use of PETG (Polyethylene Terephthalate Glycol) (a thermoplastic material) as a build material for 3D printing, especially in FDM (Fused Deposition Modeling) printers. The “G” in PETG indicates that the glycol molecule in PET, a familiar material used in the production of plastic bottles, has been modified. PETG is one of the most popular 3D printing filaments thanks to its high impact strength, low haze, and good printability
PETG (Polyethylene Terephthalate Glycol) is highly sought after for its excellent mechanical strength and resistance to water intrusion and chemical attack. PETG combines some of the good qualities of two other well-known thermoplastic materials used for 3D printing: ABS (acrylonitrile butadiene styrene) and PLA (Polylactic Acid). ABS is known for its durability and PLA for its printability.
PETG, short for polyethylene terephthalate glycol, is an adaptation of PET (Polyethylene Terephthalate). The ethylene glycol in PET is partially replaced with another molecular group, cyclohexanedimethanol (CHDM). The origin of PETG can be traced back to work done by two British scientists, James Dickson and John Whinfield, in the year 1941. PETG is a food-safe material. As a result, it is in demand as a packaging product in the food and beverage industry. PETG is also widely used for retail signage. PETG is cost-effective and less prone to warping compared to materials such as ABS. This article will discuss PETG’s characteristics, composition, recommended printer settings, and comparisons with other 3D printing filaments.
What Are the Properties of PETG Filament?
A PETG filament has certain properties that make it distinguishable from other filament materials, namely:
-
High chemical and impact resistance.
-
Good thermal stability.
-
It is a food-safe material.
-
Its extrusion temperature falls in the range of 220-260 °C.
-
It can be printed at a rate of about 40-60 mm/s.
-
The print bed must be heated to about 80 °C. Anything above this will lead to the warping of the print.
