PETG filaments for 3D printing
PETG combines strength, toughness and ease of printing. It is the ideal choice where PLA is not enough, but you want to avoid the complications of ABS: for functional parts, brackets or covers. It withstands stress and high temperatures well and prints with minimal risk of warping.
At Filamentor you will find the cheapest PETG filaments from the Smart print and Professional lab (Prof. lab) series. You get a strong material of consistent quality for hobby and professional use at an unbeatable price.
Buying guide
Why choose PETG filament for your projects
PETG combines easy printability with high mechanical and thermal resistance. This PETG filament is an ideal choice for technical parts that require strength and toughness. If you are looking for a reliable material, PETG filament offers a great price-to-performance ratio. In our selection, you will find over 90 items from established brands like Smart Print and Prof. lab, featuring a consistent 1.75 mm diameter. You can choose from many colors, including popular matte variants. We actively test our materials on our own printers to guarantee reliable results for you.
When to choose PETG for your prints
Thanks to its resistance to UV radiation, moisture, and chemicals, this material has a wide range of uses in the workshop and at home. We commonly print:
- Electronics enclosures and mechanically stressed parts.
- Holders, hooks, and organizers for the garage or workshop.
- Outdoor parts that need to withstand sun and rain.
- Spare parts for home appliances.
Recommended print settings for PETG
For a successful print, we recommend starting with the following values. Every printer is slightly different, so these figures will serve as a reliable starting point for further tuning.
| Parameter | Value |
|---|---|
| Nozzle temperature | 220 to 250 °C |
| Bed temperature | 70 to 85 °C |
| Enclosed chamber | Not required |
| Practical printing tip | Slower retractions and drying the material help prevent stringing |
Comparing PETG with other materials
You often ask us about the differences between basic materials. Compared to PLA, PETG offers significantly higher thermal and mechanical resistance. While PLA starts to soften around 60 °C and is more brittle, PETG easily handles higher loads and temperatures. However, printing with PLA is slightly easier to set up and handles very fine details better. If you are looking for a material for permanent outdoor use in direct sunlight, ASA might serve you well. This material has even better outdoor stability than PETG but requires more demanding printing, ideally with an enclosed chamber due to shrinkage during cooling.
Frequently asked questions about printing PETG
Do I need to dry PETG filament before printing?
PETG absorbs moisture from the air more than standard PLA. If your filament pops during printing or leaves fine strings on the print, we recommend drying it before use. Just place the spool in a dryer at 65 °C for a few hours.
How to prevent strong adhesion to the bed?
PETG adheres very well to the surface, which can damage smooth PEI sheets or glass beds. We recommend printing on a textured build plate or using a reliable release agent. A standard glue stick or a special 3D printing spray works well.
How much material is on one spool?
The standard package in our selection is 1 kg of PETG, which represents exactly one kilogram of net plastic weight without the spool. This size will last you even for larger and more voluminous projects. We supply all spools vacuum-sealed with a desiccant bag.
Whether you print functional prototypes or practical home accessories, you will find the right material here. If you need to restock, you can explore all filaments in our selection. For visually attractive models without reflections, matte PETG will serve you perfectly. If you are looking for a material for quick and easy prototyping, check out our PLA filaments. For the most technically demanding outdoor applications, we recommend ASA filaments. Our goal is to offer you quality materials for every project, which is why you will also find budget filaments available at an affordable price for a one-kilogram spool.
