PET-G: 3D Printing Materials Overview

The rising popularity of PET-G as a go-to filament for 3D printing can be observed both in social media and professional manufacturing. We’d like to focus on this type of material and give you advice 3D printing with it using ZMorph VX.

What is PET-G? 

Regular PET (polyethylene terephthalate) is a very popular plastic used for drink bottles, sailcloths or various containers. Mixing it with glycol (hence “G” in the name) makes the filament more practical and useful for 3D printing because it prevents corrosion and crystallization effects that can make regular PET more fragile. 

PET-G filaments are resistant to temperatures and most liquids. They exhibit stable dimensions, no shrinkage, good thermal and scratch resistance, and good electrical properties.

How to 3D Print with PET-G?

PET-G combines ABS durability with PLA printability. Its features make it a great solution for professionals seeking a reliable filament for their projects. Below you’ll find some tips on how to make 3D printed PET-G models with ZMorph VX Multitool 3D Printer.

Voxelizer Settings

Although ZMorph 3D Printers are compatible with other software, we highly encourage you to use Voxelizer for 3D printing because you can find dedicated presets for our machine.

After choosing the printer, toolhead, and nozzle, upload your model and proceed to settings. There, simply select PET-G from filament presets, decide on quality, durability, and supports and you’re good to go. If you don’t see PET-G in the dropdown menu, you have to download the preset from the online library. To do that go to Filament preset list and click the “Open filament library wizard” icon. Find the desired preset and add it to your library.

Adhesion

Use adhesive agent for the perfect first layer. If you struggle with warping and poor layer adhesion, check the ZMorph Academy. In the Basic course, there’s a 3D printing troubleshooting lesson which covers a lot of common problems.

PET-G Printing & Bed Temperature

According to our internal testing, the optimal temperature for 3D printing from PET-G ZMorph 1.75 Filament is 230-250°C. In that case, the bed temperature should be around 60-80°C.

Other Printer Settings

PET-G behaves best in a closed chamber. To receive a perfect print, close the plastic covers of ZMorph VX.

PET-G Applications

The rigid PET-G plastic can be used in many fields. The most popular applications are electronic devices housings, containers, bottles, transparent elements or photography accessories. Below you can see some sample prints made of PET-G.

Health & Safety

Although PET-G barely emits fumes and is not a toxic material, we recommend always working in a well-ventilated area. The fumes generated by melting plastic may cause dizziness and other unpleasant sensations. Should such a situation occur, stop work immediately and get some fresh air. If the symptoms do not stop, contact a doctor. 

The moving parts of ZMorph VX can suck in loose parts of your clothing or long hair. Touching the machine while working, especially the movable parts can also be dangerous. 

After the machine finishes the job, let it cool down before taking out your 3D printed PET-G model.
