Frequently Asked Questions

What is the difference between PET-CF and PETG-CF?

The primary difference between PET-CF and PETG-CF lies in their base material. PETG-CF is a reinforced material made by adding carbon fiber to glycol-modified polyethylene terephthalate (PETG), while PET-CF is to polyethylene terephthalate (PET). The key difference ‘G‘ in PETG stands for glycol. PETG is a glycol-modified version of PET that contains small amounts of glycol as a co-monomer. The addition of glycol to PETG reduces its crystallinity and makes it more transparent. However, it also reduces its strength and stiffness.

The difference in application between PETG-CF and PET-CF?

PETG-CF is a versatile basic material that is suitable for printing everyday items, such as bent, folded, and movable parts, due to its excellent toughness and ease of printing. PET-CF, in contrast, contains a greater amount of carbon fiber and is significantly stronger and more temperature resistant compared to PETG-CF. PET-CF is a professional-grade engineering material that is suitable for use in more complex and demanding environments.

What is PET-CF used for?

Due to its dimensional stability and lower water absorption rate, PET-CF is a better choice than nylon for printing functional parts used in high humidity environments. Also, its high-temperature resistance and low warping make it suitable for printing mechanical assembly parts, such as automotive accessories and fixtures.
