Nebula PETG carbon black 5 kg

Carbon Imitation

PETG is a tough material – it is extremely durable and prints without odor. It prints very nicely with a surface quality similar to PLA. Thanks to its low shrinkage during printing, this material is suitable for printing large objects. Unlike other materials, PETG is more resistant to acids and solvents, as well as to high and low temperatures. Printed objects can be heat formed or flame polished. This is another material that should be on your list right after PLA. PET-G can be quite harmful to the environment, so it is advisable to recycle it. Full decomposition of PET-G takes decades.

Here are the main advantages of printing with this material and the common properties of PETG filament:

• Very durable, more flexible than PLA or ABS, but also a bit softer.
• Hard to snap in half, so if you need an “unbreakable” case or cover, PETG beats almost everything (except Nylon 12).
• Has very low shrinkage, therefore no warping. Ideal for printing large items.
• PETG is also very strong, not brittle, but it can be scratched more easily than ABS, which is harder.
• PETG is not very good for printing supports, because it adheres extremely well. But because it adheres so well, layer adhesion is fantastic, making prints strong and durable.
• Adheres well to the build plate too, so be careful when removing it after printing.
• High chemical resistance along with resistance to alkalis, acids, and water.
• Odorless printing.

PET-G surface finishing: It is advisable to first spray the print with a filler/primer (putty used in modeling) and then sand and varnish it, repeatedly — until the surface is completely smooth — and finally spray it with paint.

Bonding PET-G: Polyurethane adhesive, cyanoacrylate (super glue), and two-component epoxy are suitable for bonding PET-G.

Recommended PET-G print settings: Commonly used nozzles are suitable. Choose diameters according to the surface finesse you want to achieve or according to the selected layer height. Printing temperature: 240 °C. Heating the bed is not required, but for better adhesion you can heat the bed up to 75 °C.

The filament is vacuum-packed together with a desiccant and placed in a cardboard box. The plastic spools on which the filament is wound may differ in relief or color. We strive to maintain 100% consistency of winding and color.
