3RDAX™ PETG 1.75mm 3D Printing Filament

ABOUT THIS FILAMENT
PETG is a strong, practical filament for everyday functional printing. It is tougher than PLA, has better temperature resistance, and gives parts a bit more durability for real world use.

It is a good step up when PLA is too light duty, but you do not want the extra print difficulty of ABS, ASA, or PC. PETG is not always as crisp to print as PLA, but it makes up for that with strong layer adhesion, better impact resistance, and parts that are less likely to crack under normal handling.

WHERE IT WORKS BEST
PETG is a good fit for everyday functional parts. Think brackets, covers, guards, enclosures, mounts, organisers, tool holders, workshop parts, and prototypes that need to hold up to regular use.

It is especially useful when you want a tougher, more durable part than PLA, while still keeping the print process manageable on a standard desktop printer. For everyday functional printing, PETG is one of the most useful materials to have on hand.

WHERE IT COMES FROM
PETG is based on PET, which stands for polyethylene terephthalate. PET is the plastic commonly used for drink bottles, food packaging, and other clear plastic containers. It is made from petrochemical feedstocks, usually derived from crude oil or natural gas.

The G in PETG refers to glycol modification. Glycol is added during production to change how the plastic behaves. In simple terms, it makes the material less brittle, easier to process, and better suited to 3D printing than standard PET.

PETG is not plant based or compostable. It is a petroleum based plastic, but it is recyclable, and clean PETG waste can be processed back into filament through suitable recycling setups. As with most recycled plastics, it needs to be kept separated from other materials and contaminants.

PRINTING WITH IT
PETG prints hotter than PLA and usually benefits from a heated bed, but it does not normally need an enclosure. That makes it a useful material for standard desktop printers when you want stronger functional parts without moving into more demanding materials.

The main things to watch are stringing, moisture, and bed adhesion. PETG can leave fine strings or small blobs if the temperature, retraction, or filament condition is not right. It can also stick very firmly to some build surfaces, so surface choice and bed prep matter.

Once dialled in, PETG is a dependable functional material. It gives strong layer adhesion, handles regular use well, and is a good step up when PLA is not quite enough.

MATERIAL COMPATIBILITY
PETG bonds well to itself, which is one of the reasons it produces strong functional parts. Good layer adhesion helps printed parts hold together under regular use, especially when the print settings and filament condition are right.

For multi material printing, PETG and PLA do not bond strongly to each other. That can be useful when one material is used as a support interface for the other, because the weaker bond can help supports release more cleanly after printing.

BASE, CARBON OR GLASS?
Standard PETG is the best choice when you want toughness, good layer adhesion, and a bit of give in the finished part. It is the most forgiving option in the PETG range and suits most general functional prints.

PETG CF adds carbon fibre for a stiffer feel, reduced flex, and a cleaner matte finish. It is a good choice when the part needs to feel more rigid or look more refined. It is also one of the most useful materials in the range when you want strong, practical parts without making the print process overly difficult.

PETG GF adds glass fibre for stiffness and dimensional stability. It is a practical reinforced option when function matters more than surface finish.

For most general use, standard PETG is the right starting point. Choose PETG CF when stiffness, finish, and everyday functional strength are the priority. Choose PETG GF when stability and practical reinforced strength are the priority.
