PETG (also called copolyester) is a modified version of PET. The modification is achieved by adding a second glycol during polymerization. The molecular structure is irregular; the resin is clear and amorphous with a glass transition temperature of 88 C (190 F).

What are the benefits?

• PETG filament has the reputation of combining the benefits of ABS (stronger, temperature resistant, more durable) and PLA (easy to print) in one material.
• The layer adhesion is usually excellent.
• You can expect less trouble with warping or shrinking of your prints.
• It’s more durable
• Also, you can have the material, prints and misprints recycled. This doesn’t mean you should start printing irresponsibly – sustainably speaking, it’s still plastic, which has to be recycled properly.
