Do you need a flexible and durable 3D printer filament for your next project? Do you wish to use a filament that offers the best of what PLA and ABS offer?
If you say “yes” to any of the questions above, you will probably love PETG filament! This 3D printer filament has great potential just like the other types of filaments because it is durable, flexible and reliable.
I understand that you are on this page because you wish to learn more about PETG filament and that’s exactly what we will give you. At the end of the article, we will give you the best PETG plastic on the market.
What is PETG Filament?
PETG filament is similar to PET (Polyethylene Terephthalate) but with enhanced properties due to the addition of glycol (PET+G = PETG). Thus, the name PETG.
PETG is as easy to use as PLA, as durable as ABS, as flexible as PET but with minimal shrinkage and warping, which makes it a great 3D printing material.
PETT (Polyethylene terephthalate) is another variant of PET. It is slightly more rigid than PETG and is popular for its being transparent.
Here are some details about PETG settings:
- Hot end 240-260 Degree Celsius
- Bed Heat 50-70
- Layer cooling fans on
- Blue Tape for Bed Adhesion
- Same speed as your PLA settings
PETG Filament Uses
Thanks to PETG filament’s easy transforming and chemical resistance properties, this can be used in various applications. PETG is commonly used in water, juice and soft drink bottles, and cooking oil containers. Since this material is FDA-approved, it’s also used in food storage containers and intricate kitchenware designs.
PETG materials are also found across the medical field, its rigid structure helps survive harsh sterilization processes making it the perfect choice for medical implants, and pharmaceutical and medical device packaging.
PETG is an excellent material for modern 3D printers. It provides easy plastic printing without compromising its overall strength and rigidity once the plastic is allowed to harden.
PETG plastic is the frequent material of choice for point-of-sale stands. It’s easy to manufacture in a wide range of shapes and colors, businesses opt for this 3D printer filament for signages that attract customers. In addition, PETG filament is easy to customize and a great affordable option.
PETG is worth considering when you are 3D printing a project that needs to be tough, durable, flexible and impact-resistant. This is also ideal for use in the production of a wide array of mechanical parts.
PETG Filament Benefits
PETG is a viable and attractive alternative to ABS and PLA. Here are some of the advantages of this 3D filament.
- Excellent layer adhesion
- Warp resistance
- Reduced shrinkage
- Higher density
- Chemical resistance to both acidic and alkali compounds
- Flexible printing on glass, acrylic, glass, blue tape, and polyimide tape
- Odorless during printing
PETG Filament Properties
PETG filament is rich with awesome properties that make it among the 3D printers’ favorite materials for 3D printing. If you are also wondering why you should get this, here are some of the reasons why you should.
One of the most impressive properties of PETG is being recyclable. Compared to other plastic filaments, PETG can be used as a gas barrier due to its chemical resistance. For 3D printers who are pro-environment, this type of filament supports your cause.
PETG filament is considered FDA-approved, so yes, it is “food safe.” However, it’s the 3D printing process that ruins it’s safety credibility because it’s difficult to clean all those little layers trap. It’s best if you still use a food-safe coating spray for your parts.
A PETG material combines PLA’s reliability and ABS’ durability. If you are looking for a 3D printing filament that combines PLA and ABS, PETG is the answer!
Reduced Warping And Shrinking
As mentioned above, PETG is as durable as PLA and as flexible as ABS but unlike the two it has minimal shrinkage and warping rate which makes it better.
PETG 3D Printing Tips
PETG filament isn’t as easy to use as PLA or ABS, but if you know how to set your 3D printer accordingly to this material, you’ll see that it’s actually not difficult to work with. For those who are new to a PETG material, this section is for you as we will be giving tips to help you enjoy 3D printing with PETG.
1. Get the First Layer Right
Getting the first layer right is essential for a successful print with PETG filament. However, this might take a number of tweaks to get the right perfect setting according to your printer. Experiment with different types of beds and adhesion methods until you find the perfect setting.
2. Print on Blue Painter’s Tape
Blue painter’s tape with or without heat is the best surface when printing with PETG plastic. It delivers a fairly smooth finish that is not glass-like. By using blue painter’s tape you’ll have to clean off any tape that sticks to the part and not ruin your build surface since you can apply it right over the top of any other build surface.
3. Get the Right Temperature
Keep an eye on your project while printing. How much filament doesn’t end up where it’s supposed to? Remember this, PETG filament is prone to stringing and oozing and might stick on the nozzle and end up deposited on another part of the print. When this happens, you will certainly not like it.

Best PETG Filament
I understand that at this point, you want to know the best PETG filament on the market. A number of brands claim to be the best but not all of them deliver what they promise.
To cut your research time short, we present you the top PETG material today. This is our best choice in terms of quality, performance, and price.
Overture PETG is as easy to use as PLA and as durable as ABS. In short, this offers the best of both filaments for a more enjoyable 3D printing experience. It doesn’t require a head bed, offers easy bed adhesion, is stiff and has a glossy type of finish.
Initially, I thought Overture PETG would be unremarkable, but I was wrong. I know that PETG is not easy to use but I’m surprised that this is not that difficult to handle.
Each Overture PETG comes with two pieces of quality 200 x 200mm filament. This is designed and manufactured with Clog-Free patent to guarantee a smooth and stable 3D printing experience.
The brand is also very careful when it comes to handling the filament because they know that PETG is sensitive to moisture, so they pack this in a complete drying 24 hours before vacuum aluminum foil packaging.
Overture is capable of manufacturing all kinds of filaments in large scale with premium quality. Their filaments are cost-effective and reliable. Most importantly, it is compatible with most common 3D printers including MK3, Ender 3, Monoprice FlashForge and more.
Overall, this brand is a killer deal for a great filament in terms of price, performance, and quality of 3D prints. We highly recommend this!
PETG filament is one of the most popular 3D printing filaments today. More and more are using this material due to its flexibility and durability. PETG material is highly recommended for those who are looking for new 3D printer filaments. If you are considering to try a new material other than ABS and PLA then get a PETG filament as it offers the best of both worlds.
The only downside with PETG filament is that it tends to be more expensive than the other aforementioned materials. However, in terms of quality and results, you can rely on this.
