### PETG FAQ

<details>

<summary><strong>Are there any printing requirements?</strong></summary>

No! The exceptions would be our Fiberon™ PET-CF17 and PETG-rCF8, which require a hardened nozzle due to abrasiveness, but the rest of these materials can print on any printer setup.

<details>

<summary><strong>What is difference between PolyMax™ PETG and PolyLite™ PETG?</strong></summary>

PolyMax™ PETG offers better mechanical properties than any other regular PETG making it a good candidate for a wide range of applications.

<details>

<summary><strong>What is PETG?</strong></summary>

If we had a simple axis going from "low durability but easy to print" on the left to "high durability but challenging to print" on the right.\
PLA would be in the far left, ABS would be in the far right and PETG would be exactly in the middle.\
Printing temperature: (PLA+ABS)/2\
Heat resistance: (PLA+ABS)/2\
Strength: (PLA+ABS)/2

<summary><strong>What is the difference between PCTG and PolyMax™ PETG?</strong></summary>

*A little bit of Material Science first:*\
PET is made from terephthalic acid ('TPA') and ethylene glycol ('EG') (CH2OH)2\
PCT is made from terephthalic acid ('TPA') and cyclohexanedimethanol (‘CHDM’) C6H10(CH2OH)2\
\
If you react TPA with both EG and CHDM, you get a co-polymer, called PETg or PCTg.\
\
Usually the polymer is called PETg when the major diol is ethylene glycol (>50%) and PCTg when the major diol is CHDM (>50%).<br>

The higher the EG content the stronger and more rigid the material, the higher the CHDM content the more ductile and impact resistant the material.

In summary:\
PETG -> Strong and rigid\
PCTG -> Ductile and impact resistant

Our PolyMax™ PETG is a modified PETG with enhanced fracture toughness which makes it more ductile and impact resistance.

To conclude, PolyMax™ PETG provides the best of both PETG and PCTG with high strength and rigidity as well as enhanced ductility and impact resistance.

<summary><strong>What is the difference between PET and PETG?</strong></summary>

PET and PETG differ in their chemical structure, properties, printability, and applications. PETG is more flexible, easier to print, and suitable for 3D printing and medical applications, while PET is more durable and suitable for applications requiring thermal resistance.

<details>

<summary><strong>Will the spools work in an AMS?</strong></summary>

Yes! We have redesigned the edges of our spools so all Polymaker products will now spin great in the AMS.

</details>

<details>

<summary><strong>I want a strong PET(G) - what do you suggest?</strong></summary>

This will depend on what kind of "strength" you require, but [Fiberon™ PET-CF17](https://us.polymaker.com/products/fiberon-pet-cf17) is an overall great material for a vast array of applications.

[PolyMax™ PETG](https://us.polymaker.com/products/polymax-petg) will offer the best impact resistance.

[Fiberon™ PETG-ESD](https://us.polymaker.com/products/fiberon-petg-esd) will be the best bet if you require electrostatic discharge safety.

<summary><strong>What is the difference between PolyLite™ PETG and Polymaker™ PETG?</strong></summary>

Polymaker™ is the new and improved PETG formula made by Polymaker, designed for high speed printing and amazing layer adhesion. &#x20;

**Polymaker™ PETG:**

* Prints faster, up to **300 mm/s**
* Has **much better layer adhesion**
* Uses a higher cooling range: **20–60%**
* Tolerates more aggressive printing while keeping strength and finish
