What is PETG Filament?

PETG is an acronym that is used for describing Polyethylene terephthalate glycol. It is a kind of thermoplastic polyester that provides extra toughness to your final 3D print module. This filament option is well known for its high-end strength. One can easily access very sturdy and strong prints with the help of PETG filaments. The best thing about PETG filament is that it has very low shrinkage quality and is absolute perfection to be used on larger flat printing surfaces. 

If you are willing to have a 3D printer that can provide you significant chemical resistance, formability for manufacturing, and high-end durability, PETG filament is an option that we would advise you to have on.

PETG is an adaption to PET i.e. Polyethylene terephthalate whereas the G included here stands for the glycol molecule. If we compare both PET and PETG options, we will find that the PET filament includes the same monomer units as the glycol-modified PETG does. PETG possesses higher strength and durability than that of the PETG filament and also being more impact resistant and well suited for higher temperatures.

Polyethylene terephthalate glycol does have low forming temperatures and that makes it easier for the users to create a wide range of consumer and commercial applications by adding vacuum and pressure on it. The involvement of the low forming pressure has made the PETG filaments made of the widely used materials for 3D printing and heat forming processes while having a smooth surface finish. One can easily bend the PETG filaments and can use die-cutting and routing with it. 

The majority of the plastic bottles and sailcloths available today are made up of PETG filaments. PETG is one of the finest options where you can easily access the durability of ABS and printability of PLA at an easier end. And that is the reason why the majority of the professionals today use PETG as their reliable filament option for creating a wide range of applications.

A Brief Introduction To History

The journey of the PETG filaments was initiated with the invention of PET in 1941. In the mid 20th century, scientists have started looking for new substances rather than just depending upon the traditional organic compounds. Polymers like phthalic acid are already there in the market but they are too soft that one cant use them as fibers and the glycol-based 3D printing materials do have so low melting points that they can be used in textiles.

The esterification process was being used to heat the glycols with terephthalic acids that help in creating the long-chain molecules of PET successfully. These PET molecules turn into fibers that own higher melting points and lower dissolvability. PET became a very important part of the textile industry from 1946 to 1952. It was used as a film for packaging food. In 1976 PET was started to be used in the construction of rigid bottles that can well manage carbonated drinks and mineral waters. PET fibers have a lot of disadvantages. It is quite susceptible to crystallization at higher temperatures and that is the main reason why scientists get shifted towards the PETG materials.

The ethylene glycol was being replaced from the molecular chain of PET with a larger monomer unit i.e. cyclohexane dimethanol to create PETG. The introduction of cyclohexane dimethanol has solved the problem of crystallization and has provided customers with a better material for 3D printing that can provide them with absolute heat resistance and impact resistance. PETG is a wonderful option that can be used for thermoforming. It can easily bear a higher extruder temperature and can be used in a wide range of applications without losing its qualities.

Where do we use PETG filaments?

The PETG material is being used in a wide range of applications, especially tough material today. It is quite resistant to heat and impact and that’s why it has emerged as a very crucial part of industrial usage. Right from packaging medicines to advertising and creating electronic insulators, PETG is an option that serves to be best in different environmental conditions. 

PETG filament is an ideal choice that is being widely used in different 3D printing options. The best thing about PETG filaments is that one can easily sterilize the item created without any issues. PETG includes a very good adhesion between the layers. 

These filaments do have minimal deformation during printing and are resistant to different chemicals and adverse temperature conditions. The best thing about PETG filament manufacturer is that it does not produce any kind of odor during printing. If you are looking for creating perfect 3D prints with absolute flexibility and great resistance to shock, PETG is a wonderful option that we would surely advise you to have on.

Is PETG eco-friendly?

The answer to this question depends upon your usage. PETG just like other plastic materials can serve to be quite harmful to the environment but if you recycle it, it can serve to be a better solution.

It takes decades for breaking down the PETG filament completely into a landfill. The best thing you can do with PETG is to recycle it. PETG can be easily recycled to create new products and hence can serve to be an environment friend option. Different chemicals are usually being used for breaking up the polymer chains of PETG. The components thus formed can be used as raw materials for the manufacturing of the new materials. The best thing about PETG is that it will not lose its original chemical properties during the entire process.

Recycling PETG is a great option to prevent different types of pollution. It prevents the breakdown of the final product into microscopic fragments that can badly affect our environment and can threaten wild and aquatic life.

What are the Properties of PETG?

PETG is one of the finest 3D printing filament options that does comprise the combined mechanical properties of both PET and glycol. It provides a glossy finish to your final product while maintaining its toughness as well This filament option not only provides sturdy and hard 3D prints but is also quite resistant to impact, heat, and chemicals. Transparency and ductility are one of the two major properties that PETG is well known for. 

The best thing about PETG is that it is designed to be quite compatible with different food uses. PETG includes an extrusion temperature between 220 degrees to 260 degrees. Moreover, it can provide you with an absolute print speed of 40-60 mm/s. 

Despite such a huge range of positive points, PETG includes some negative properties as well that we can’t ignore. PETG usually gets easily warped off. To avoid the issue of warping, you need to use a heating plate with it always. Moreover, PETG is also supposed to be quite prone to scratches. PETG filaments work well only under 80 degrees Celsius. Absorption of moisture quite quickly is one of the other major issues with PETG that can affect its performance badly. It is always advisable for the consumer to place the PETG material in a cool and dry environment.
