PETG 1.75mm 3D Printer Filament
- Not tried PETG 3D filament before? It’s your next favourite filament. It’s extremely durable, a little flexible, and easy to print. While prints with other PET (think plastic bottles) or PETG filament can be easily plagued with stringing or blobbing, our formulation prints smooth with an excellent finish.
- PET-G described in a nutshell? Prints as nice as our PLA, just stronger, more durable and with a shinier finish. Due to PETG’s nature, the layer adhesion is unparalleled, giving you near-unbreakable parts. Our customers especially love printing drones or other high-impact projects from this versatile material.
- You’ve not seen colours like our PETG colours. While we now offer some PETG in opaque colours, our original line is a beautiful selection of rich, deep tones. Check out some of our customers’ prints in the reviews below.
- Like all rigid.ink filaments, our contaminant-free PETG resin is extruded to industry-leading tight tolerances of just 0.03mm+/- of our stated 1.75mm diameter. This doesn’t just guarantee jam-free printing: it ensures consistent layers giving uniform strength and finish quality through the part. We guarantee 100% reliability. Every. Single. Time.
- Once you read our collective thousands of reviews, Googled us and watched countless Youtube testimonials – you’re sure the rigid.ink quality is there. But what about our customer service? Don’t worry: our friendly, efficient and knowledgeable technical services are on hand to assist with any issues.
PETG Filament 1.75mm
Are you getting bored with PLA or ABS as your go to print material?
Maybe you’re looking for something that is stronger than PLA, but is easier to use than ABS?
If so, then rigid.ink PETG 1.75mm filament is likely to become your new favourite filament.
rigid.ink PETG is a co-polymer that combines Polyethylene Terephthalate (the material that most plastic water bottles are made of) with Glycol. The result is an extremely tough and durable material that’s easy to use. In a way, rigid.ink PETG is the best of both worlds. It combines the strength and rigidity of ABS with the relative ease of use that comes with printing with PLA. Commercially, PETG has literally thousands of uses.
The strength of PETG makes it a natural for food packaging. In addition, its natural chemical non reactivity means that it is invaluable in medical applications. It is also used in signs, orthotic and prosthetic devices and a wide variety of machined uses.
PETG is certainly strong. In fact, you’d be hard pressed to break it in half. This means that if you need to print an object that that is highly break resistant, you’d be hard pressed to beat rigid.ink PETG filament.
At the same time, rigid.ink PETG is also very flexible, more so than both PLA and ABS. It’s also more malleable. This means that rigid.ink PETG works well as a prototyping material and in end use applications. Its strength also means that it can stand up to any number of post-printing processing techniques, including, sanding, grinding, cutting and machining.
When printing, rigid.ink PETG filament exhibits incredible layer adhesion. The strong bond between the layers of your printed objects means that rigid.ink PETG exhibits very little warping from shrinkage as it cools. This makes rigid.ink PETG ideal for printing larger objects.
rigid.ink PETG is very water resistant. This makes it an excellent choice for outdoor applications. It also offers great chemical resistance, standing up well to both alkaline and acidic environments. Finally, rigid.ink PETG is very impact resistant. This makes it a viable alternative to PMMA and Polycarbonate.
A quick look at the data stats demonstrates the versatility of rigid.ink PETG:
- It has a specific gravity of 1.27g/cm3, that’s just higher than PLA and about 20% more dense than ABS.
- It has a weighted strength rating of 55.5 kg/122.36 lbs.
- Its Rockwell hardness rating of R106 makes it comparable to ABS.
- However, its tensile strength yield of 53 MPa or 7700 psi, elongation at break of 50% and flexural yield strength of 77 MPa or 11,200 psi, leave ABS in the dust.
rigid.ink PETG comes in a variety of translucent and opaque colours and prints easily, cleanly and with no odour. Your objects will end up with a nice glossy finish. Depending on your extruder, rigid.ink PETG filament has a print temperature of 235C to 245C and works well with a heated bed temperature of about 70C to 80C. As to print surface, rigid.ink PETG is quite forgiving, blue painters tape works well or vinyl-based hairspray.
It’s important to remember that rigid.ink PETG doesn’t need to be forced onto the bed. A slightly larger gap on the Z axis will give the material enough room to lay down properly. Finally, rigid.ink PETG will bond to the previous layer of material ridiculously well. That means for the strongest possible object, leave the fan off. However, if you want to bring out the detail in your object, do use the fan. The rapid cooling will make your object’s details pop.
It’s important to remember that PETG, like a lot of thermoplastic filaments, is hygroscopic. This means that it will absorb moisture directly from the air. This means that you should store your rigid.ink PETG in a cool, dry place in order to maintain its strength and integrity. All rigid.ink orders come with our specially designed resealable rigid.ink foil bag and silica gel for the best storage.

Let’s be honest, shall we?
Printing Temperature: 220°C
Bed Temperature: 70-80°C
Bed Adhesion: Blue decorators tape, Glue-stick
Print Speed: 30-40 mm/s (higher speeds may need slightly hotter printing temp, up to 245°C)
Cooling Fans: Usually off, unless needed for finely-detailed parts
Z-Axis: Increase Z-axis gap, almost air printing. Increase by 0.02mm each time to prevent stringing/blobbing.
Good ventilation is essential and do not leave print unattended.
Glass Transition Temp: 80°C
Tensile strength: 7,300 psi (50MPa)
Sample Weight: Approx 35g
Empty Spool + Filament Weight: Approx 250g + 1KG = Approx 1.25KG

Really great filament, easy to print with. So far I have tested white transparent red and glass PETG on Delta and Cartesian printers, always with great results.
Adorund 2 to 4 times the filament got bending problem near the extruder gear . I don't know y thought . I liked the filament more than pla and the durability of the filament but the extruder problem prevents me from getting more
Bought a 1kg spool of so called Translucent Black as I wanted the translucent shimmer of black rather than near solid black. After setting of a large print I was very disappointing to see some very grey objects! The PETG Green is a good strong green but this has put me off completely. No wonder its now in the "sale". See https://www.thingiverse.com/make:378378 for some clearly grey prints!
great filament at good price
