PETG is a tough material – it is extremely durable and prints without odor. It prints very nicely with a similar surface quality to PLA. Thanks to 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 high and low temperatures. It is possible to heat shape a printed object or polish it with fire. This is another material that must be on your list immediately after PLA. PET-G can be quite harmful to the environment, so it is advisable to recycle it. Complete decomposition of PET-G takes decades.
Here are the main advantages of printing with this material and common properties of PETG filament:
Very durable, more flexible than PLA or ABS, but also slightly softer.
It is difficult to break in half, so if you need an "unbreakable" case or cover, PETG beats almost everything (except Nylon 12).
It has very low shrinkage and therefore does not warp. Ideal for printing large items.
PETG is also very strong, not brittle, but 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, so prints are strong and durable.
It also adheres well to the print bed, so be careful when removing it after printing.
It has high chemical resistance along with resistance to alkalis, acids, and water.
Printing is odorless.
PET-G surface treatment: It is advisable to first spray the print with filler (putty used in modeling) and then sand and repaint again and again - until the surface is completely smooth, and finally spray with paint.
PET-G gluing: Polyurethane glue, cyanoacrylate glue, and two-component epoxy are suitable materials for gluing PET-G.
Recommended settings for PET-G printing: Commonly used nozzles are suitable. Diameters can be chosen according to the surface fineness we want to achieve or according to the layer thickness settings during printing. Printing temperature: 240 °C. Bed heating is not required, but for better material adhesion, we can heat the bed up to 75 °C.
The filament is vacuum-packed along with a moisture absorber and placed in a cardboard box. The plastic spools on which the filament is wound may vary in design or color. We strive to maintain 100% repeatability of winding and color.
