PET vs PETg Filament – What’s The Difference?

“PET filament”, “PETg filament”, “PETG filament” “PET-G filament” – all of these are common names used in 3D printing. Whilst at first glance “PET” and “PETg” may appear to be the same material, their (incorrect) interchangeable use by material companies and 3D printer users alike can be misleading. This article explains the difference between the two filament materials and summarises the benefits and disadvantages of both. 

PET (Polyethylene terephthalate)

  • Higher working temperature
  • More rigid
  • More brittle

If you are looking to get a print out that is rather rigid, PET 3D printer filament is the right material for this occasion. It has a slightly higher working temperature compared to PETG and is rigid, much like PLA. Although prints made with PET are hard, they are prone to be broken easily. So be aware if you know that your part is going to be subjected to a considerable amount of stress as the plastic would break rather abruptly, with not much sign of plastic deformation.

Did you know? Our ONE PET 3D Printer filament contains 100% recycled content made from waste PET plastic bottles.


PETg (Polyethylene Terephthalate Glycol)

  • Has glycol added (hence the “g”)
  • Slightly more flexible
  • Greater impact resistance
  • Absorbs more moisture (Dehydrating PETg before use is a good idea)

PETg can simply be thought of as PET with glycol added. The addition of glycol allows the material to be slightly more flexible, but not as much as TPU or TPE. Having a little more flexibility allows parts to have a greater tolerance to impact compared to PET.  Be careful of how you store your PETG as the addition of glycol means that the material absorbs more moisture. Ensure that you keep your PETg 3D printer filament in an airtight environment or dehydrate it before use.


Technical Data Comparison















Whilst PET and PETg plastic 3D printer filament may sound as though they are very similar, it is important to remember that they offer different properties – which should be compared when choosing the most appropriate material for your project.

To summarise – where our regular PETg has a better impact resistance, ONE PET boasts superior technical properties such as tensile strength, not to mention the environmental benefit of 100% recycled content. 

Both and PETg plastic 3D printer filament can be found in our shop

Happy Holidays from the Filamentive Team!

Happy Holidays from the Filamentive Team! 2018 has been a tremendous year for us and we’d just like to thank each and every customer, supplier and partner!

In February, we made the switch from plastic to cardboard spools – reducing our plastic use and making recycling easier for our end-users. 

March saw us shortlisted for the prestigious 3D Printing Material Company of the Year award. 

In April 2018 we announced our Distribution and Reseller Agreement with 3DGBIRE. As a direct result of this, technology distribution giant Farnell element14 became stockists of the entire Filamentive range.

After a busy Summer we then joined our friends 3DGBIRE at the TCT Show 2018. This was a wonderful platform to see customers – new and old – and also forge new relationships.

Very recently, in December 2018, we announced Proto21 as exclusive Filamentive distributor in GCC region. As a result, Filamentive products are now available in UAE, Bahrain, Saudi Arabia, Oman, Kuwait, Jordan, Qatar.

What to look forward to in 2019

In January, we will be releasing, not one, not two, but THREE brand new 3D printer filament materials! 

  • ePLA – engineering-grade PLA filament – with the performance of ABS, 95°C heat resistance (after annealing) and the ability to print at speeds above 120mm/s – up to 90% recycled
  • PLA Matte – as the name suggests, surface diffuses light to give it a matte look, and creates a textures finish to reduce visibility of layer lines – 75% recycled material
  • ONE PET – 100% recycled filament made from post consumer PET waste. Developed by our partner Tridea – it is stiff and tough material with excellent interlayer adhesion, not to mention that it is available in a wide range of colours to suit needs and requirements.

Release dates and availability announced in due course 👀

2018 was a truly tremendous year and thanks to you we are well placed to have an even better year in 2019 and beyond. Everything we do is for YOU and we will always be committed to providing high levels of quality, sustainability and customer service.

PLEASE NOTE: We will be closed between Monday 24 December and Wednesday 2 January. All orders and emails received in this period will be dealt with upon our return on Thursday 3 January.

As a token of our appreciation, please use discount code xmas20 at checkout for 20% OFF ANY ORDER – Ends Friday 4th January 2019

A Merry Christmas and Happy New Year from all at Filamentive! 🎅🎄 See you in 2019! 


Filamentive announce Proto21 as exclusive distributor in GCC region

Bradford, West Yorkshire, United Kingdom – December 6th 2018 – Filamentive, a UK based company, is proud to announce a distribution partnership with Proto21 3D Printing LLC, to introduce their high-grade, environmentally friendly 3D Printing filaments in the GCC region (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and UAE).

As a 3D printing business in the region, Proto21 found it challenging to find a local supplier of high quality 3D printing filaments. Trying the top brands, which were found to be expensive, with a long delivery time, which was incompatible for rapid prototyping.

During the hunt for reputed and high-quality filaments, Filamentive was a must try considering the environmental ideologies and responsibilities. After testing some spools of different materials and see highly satisfied results, Mr. Pir Arkam, the founder of Proto21 3D Printing LLC, immediately reached out to Mr. Ravi, the director of Filamentive, with a proposal to become a distribution partner in the GCC region.


What is the need for environmentally sustainable raw material in 3D Printing?

Currently, PLA is one of the most commonly used materials in 3D printing. While it is plant based, PLA is not the solution to the environmental concerns. Most importantly, PLA will challenge the food and energy security in the future. Also, PLA can take hundreds of years to breakdown naturally.

“90% of all plastics we use come from non-renewable sources. As 3D printing grows, this will only exacerbate the issue. It is a social responsibility of every 3D printing professional and company to address the environmental impacts of using plastics.” Added by Mr. Pir Arkam.

Filamentive chooses to address environmental concerns with the use of recycled materials where possible without compromising on the quality of the product. All the Filamentive products are manufactured by recycled plastic materials, keeping the environment in mind. This ambitious organization has been globally recognized as “One of the Most Impactful Startups” by Web Summit in 2017.


The Partnership between Proto21 and Filamentive

“It is such a pleasure to introduce our recycled filaments in the exciting 3D Printing market of the Middle East, through a company possessing similar environment values,” Mr. Ravi Toor, founder of Filamentive says. “Looking forward to working with Proto21 3D Printing LLC to spread our idea, serve the industry with our environment friendly filament and promoting the use of recycled filaments in 3D printing industry.” he further commented.

All common filament material in FDM industry will be supplied by Proto21. The list of materials which will be available in the region include rPLA, PLA Cosmic rPET-G, rABS, ASA, Carbon Fiber & Wood fill. “Considering the rapid prototyping industry, we will ensure the fastest delivery with competitive prices”, Mr. Arkam said.

Used by more than 3000 makers, 3D Hubs, businesses and universities – this recyclable 3D printing material is now available in GCC countries (UAE, Bahrain, Saudi Arabia, Oman, Kuwait, Jordan, Qatar) with Proto21 as the exclusive distributor in the region.
