Polyethylene Terephthalate Glycol PETG is highly sought for its excellent mechanical strength and resistance to water intrusion and chemical attack. The origin of PETG 3d printer is traced back to work done by two British scientists, John Whinfield and James Dickson, in 1941. They used a procedure called esterification to heat glycols with terephthalic acid.
The two scientists created a long-chain molecule of PET that could turn into the fiber with high dissolubility and melting point. It became the mainstream material for textile industries, then in the food packaging industry. However, it had a weakness of high crystallization temperature, which made it easy and opaque. This later started a demand for something more robust and reliable, hence the introduction of PETG. It was created by replacing ethylene glycol in the molecular chain with a larger monomer; cyclohexane dimethanol stopped the crystallization associated with PET.
Therefore, PETG filament for 3D printing entered the market and got accepted by manufacturers for its toughness and also other advantages, which mostly rely on its properties such as;
- It has excellent thermal stability; its thermoforming property makes it efficiently heated and formed to specific molds.
- It is a food-safe material.
- It has a high chemical and impact resistance.
- The print bed can be heated to about 60 to 80 degrees.
- With a Snapmaker printer and PETG filament, the printing speed is user-defined.
- The possibility of PETG filament shrinking or warping is very low.
- Its various available colors make it ideal for mixing colors and creating a beautiful colorful object.
