The perfect all-round plastic for your prototyping needs. PETG is a popular 3D printer filament. The ‘G’ stands for “glycol-modified”, and the result is a filament which is clearer, less brittle, and most importantly, easier to use than its base form. For this reason, PETG is often considered a good middle ground between ABS and PLA, the two most commonly used 3D printer filaments, as it is more flexible and durable than PLA and easier to print than ABS.
The material is strong and extremely versatile, easy to paint and post process making it the perfect choice for almost any 3D printing project.
PETG CHARACTERISTICS:
Tolerances: ±0.5% with a lower limit of ±0.5 mm (±0.020″)
Max Part Size: 450 x 450 x 470 mm
Layer Height: 100 – 300
Infill Options: 20% Standard – 80-100% High Infill
Wall Thickness: 0.8 mm
Strengths | Weaknesses |
|---|---|
Low-cost, fast turnaround times | Limited dimensional accuracy, print layers are likely to be visible

PETG is a good all-rounder but stands out from many other filaments due to its flexibility, strength, and temperature and impact resistance. This makes it an ideal 3D printer filament to use for objects which might experience sustained or sudden stress, like mechanical parts, printer parts, and protective components.

≥ 0.6 mm
Vertical features are often overlooked but they play a very important part in whether or not your print will be successful and how strong the final result will be. We always recommend designing walls with a thickness of at least 1 mm with a minimum viable thickness of 0.6 mm.
≥ 1.6 mm
In order to achieve the best results we recommend a minimum thickness of 0.6 mm for unsupported walls.
≥ 3 mm
Pins and columns are often used in electronic and end product casings. For best results avoid designing pins with a diameter smaller than 3 mm.
TIP: Adding a chamfer or fillet at the base of your pins will result in much stronger parts.
≥ 1.6 mm Thickness
≥ 0.5 mm Depth
Embossed details should have a minimum line thickness of 1.6 mm and a depth of 0.5 mm or higher.
≥ 1.2 mm Thickness
≥ 0.3 mm Depth
Engraved details require a minimum line thickness of 1.2 mm and a depth of at least 0.3 mm.
≥ 0.4 mm
When designing an assembly of parts we suggest leaving a clearance of at least 0.4 mm around moving/sliding parts.
Our PLA / PETG / ABS / PC requires supports in order to print overhanging areas. It’s important to keep this in mind during the design phase since the surface in contact with the support material will exhibit a rougher finish compared with the rest of the model.
