PETG 3D Printing 

One of the material options for our 3D printing on demand services is PETG. What does printing with PETG achieve? What are its benefits and suitable uses? Why has this particular filament become one of the industry standards and the most popular materials for printing?

What is PETG?

PETG is also called glycolized polyester. It’s a plastic which can be made to be 100% recyclable. “PET” is in many ways the predecessor to this material. PET stands for polyethylene terephthalate, and this material has been used since the 1980s to manufacture plastic items. PETG is a newer version which has had glycol added, this makes it less brittle and fragile. PETG has become one of the industry standard materials for 3D printing. 

PETG’s properties include strength similar to ABS filament but also simplicity which you could compare to other materials such as PLA. 

It is technically a “copolymer” and it combines properties found in both PET and in glycol, as the two have been combined. PET has issues regarding being too weak and brittle, and very susceptible to temperatures and some chemicals. PETG combats this, as it has much better thermal stability. 

PETG 3D printing is also used a lot when it comes to food and drink. It has a hardness to it, and other properties that make it ideal for edible contents. It can be made transparent so that people can see exactly what is within, has thermal stability to deal with the different temperatures food and drink is kept at, and also does not impart any chemicals or other harmful materials on the food or drink. 

3D Printing with PETG

What does printing with PETG entail? There are a number of different 3D filaments available on the market using PETG and variations of this material. The actual process of 3D printing is relatively straightforward but there are some issues that can occur if you don’t have the right equipment or you get something wrong during the process. 

“Stringing” is a common issue with printing with PETG. A professional service for 3D printing can ensure that you are far less likely to experience this stringing issue, which can leave short strands where you don’t want them in the printing process. 

A heated bed between 75-90 °C is required as well as an extruder that is around 230 °C for the best results. 

Advantages of PETG 3D Printing

Each and every type of material used for 3D printing has its pros and cons, this is why there are so many different types available, so you can match up the filament to the purposes you will be using it for. What are the advantages of 3D printing with PETG filament? This is an extremely common material, so the numerous advantages are definitely worth considering. 

  • PETG adheres to your printing bed and it is unlikely to warp as you print it.
  • It is mainly odorless, unlike some other 3D printing materials which can have quite pungent smells.
  • PETG is much more durable and less brittle than PET, which has been popular in plastic printing and manufacturing for decades.
  • PETG is suitable for use with food and drink, which is not true of a lot of the other materials.
  • It is also suitable for use in a variety of temperatures.
  • The PETG filament, once printed, can handle sunlight and water, making it better for any outdoor uses. 

There are some disadvantages of PETG, but these are mainly to do with common stringing in the printing stage. Using a 3D printing service online can take these issues out of your hands.
