3D Printing with PETG Filament

I would just like to start off this blog with just reminding you how awesome 3D printing is. The fact that we as a society have gotten so far that we can make our thoughts come into reality in a matter of hours is absolutely astounding. This blog will be revolving around 3D printing with PETG. From the specifications to how to get decent 3D Prints with this remarkable material. Without further delay let's learn about PETG material.

So we can first start off with what PETG stands for. PETG stands for Polyethylene terephthalate which is another chemical name for an awesome material. We're just going to stick with PETG because its a much easier acronym to pronounce. PETG is not just another FDM plastic material you can 3D Print with your 3D Printer. PETG is a material that has some pretty unique properties.

Some of those properties include having a high durability, chemical resistance and being food safe. Now that's great and all but what do those really mean? we'll I'm glad you asked.

High Durability

Having a good durability for 3D Printing PETG is important because this allows you to design a part with PETG in mind. Having good durability allows your 3D Printed PETG parts to withstand immense pressure from external forces for example: Standing on the part or driving over the part with a car. Now maybe not the second one however, depending on how you design your part. You can easily 3D print something in PETG to withstand the pressure of a full grown adult male. Now we found an awesome video on YouTube showing the strength of PETG.

Chemical Resistance

Now Chemical resistance is really not something people look for when researching a 3D Printing material however, it is a pretty good factor to look up to prevent unwanted results from happening. Because these are plastics and plastics are known to be reactive with certain materials it is good to know what PETG reacts with.

For example PETG material CANNOT handle any form of Potassium hydroxide contact at any concentration. Whether it's 30% water and 70% Potassium hydroxide. It CANNOT handle it. It will begin to dissolve and break down due to the reaction taking place between the two materials. 3D Printed PETG can however, handle other chemicals such as: Wine vinegar, Styrene and Fluorhydric acid.

Now what this means is that PETG can make contact with certain materials and now break down. We found this information at They have a great big table showing you what PETG Material reacts with and what it does not.

Food Safety

YAY you can 3D print cups, forks, spoons and plates right? Of course you can but you should consider these tips from hackaday blog post PLASTICS: PETG first before you do. Hackaday talks about PETG in depth and what you can use it for.


Now let's get into the specifications of 3D Printing PETG. Now because of PETG's great characteristics and benefits it does come with its downside. 3D Printing PETG requires an extruder heat temperature of 235 and 250°C. Not only that but in order to 3D Print PETG you also need a Heated bed with a Temperature of 80-100°C. The power consumption does increase drastically when requiring a Heated bed. Power consumption rates increase upto 280 watts of power every hour!

Not only that but you also need an fan blowing on the 3D Printer extruder head so the material cools down extremely quickly.

PETG is not all that bad though. Once you jump over the hurdles of getting PETG to 3D Print you can enjoy great durability, Chemical resistance and food safety. If your looking to 3D Print PETG you can always buy your own 3D Printer and material below! As alway have a great day!
