Prusament PETG Transparent 1.75mm 1kg

Transparent colors

Prusament PETG is a high-quality filament manufactured by Prusa Research with exceptional strength, flexibility, and ease of use. Designed for functional parts and everyday 3D printing, it combines the durability of PET with the easy printability of PLA. Each spool is meticulously produced and tested to ensure precise diameter, consistent color, and reliable results.

About PETG

PETG is one of the most widely used filaments. Its strength and durability make it an excellent choice for printing various mechanically stressed parts, such as various holders or clamps. Due to its excellent layer-to-layer adhesion, PETG prints are ideal for waterproof applications both indoors and outdoors. In addition, PETG is a tough material with good heat resistance. The G in the abbreviation stands for a glycol-modified substance that is included in the manufacturing process. This modifies the properties of PET, making it easier to print, less brittle and clearer, especially when printing semi-transparent variants.

PETG has a low thermal expansion, so even when printing large objects, and without an enclosed environment, it rarely lifts off the plate and deforms. Additionally, PETG is tougher and less brittle than PLA. It has a suitable amount of flexibility that can prevent parts from cracking under load. We use PETG to print parts for our own printers!

What can you expect?

Prusament PETG is our own, in-house manufactured filament. The entire production process is closely monitored and tested – we guarantee a precision of ±0.02 mm and very consistent colors. You can inspect the parameters of every spool we have produced at prusament.com. Check out the sample spool !

Manufactured in-house by Josef Prusa

We weren't satisfied with the quality of the filaments available on the market. So we decided to make our own! Prusa Research is the only 3D printer manufacturer with its own filament production.

Premium quality materials and thorough testing

The entire manufacturing process is monitored and tested – wire diameter, color consistency and mechanical properties – to ensure that every spool is perfect.

± 0.02 mm guaranteed manufacturing precision

We believe that the industry standard of 0.05 mm is not sufficient for perfect 3D printing. That's why we guarantee ±0.02 mm precision and highly consistent colors in our filaments.

High quality that you can check for yourself

We are the only manufacturer that allows you to inspect the parameters of each individual filament spool. Scan the QR code on the spool to see all the details online ( check out the sample spool ).

Print setup

Nozzle: 250 ±10 °C
Heating bed: 80 ±10 °C
Recommended steel surface: Textured / Satin

Before printing, you should read our dedicated article and materials table on preparing the printing surface.

Basic properties

Beginner tips and tricks

Unlike PLA or ABS, PETG tends to flow a bit and can leave plastic threads on your print. We recommend drying the filament before printing, as described here. If stringing still occurs, you can counteract it by increasing the retraction and adjusting the hotend temperature — but if you are using our filament presets in PrusaSlicer, we have already done this for you and the amount of stringing should be minimal. You can also remove the threads afterwards by briefly giving the finished print a heat gun.

Notes

• This PETG is manufactured in-house by Prusa Research.

• 1.75 mm filament is produced with a precision of ±0.02 mm.

• Before printing, ensure that the heated bed surface is clean, as described in the 3D Printing Handbook.

• If you choose a 2 kg spool, you will need to download and print the holder for 2 kg spools as it will not fit in the standard spool holder.

• To dry the filament, follow the instructions in our article.
