ERYONE High Speed PETG Plastics 1.75mm 1kg 3D Printing Filament Color High Toughness Factory Supply Fast Speed Coils

PETG is chemically similar to the plastic that water and soft drink bottles are made of, and is a great alternative to ABS. It has the heat-resistant properties of ABS without the toxic fumes and can be sanded much like PLA. Most FDM printers that can print PLA can print PETG, though it takes a little more effort to get right.

PETG has become a very popular 3D printing material thanks to it's ease of printing, mechanical strength, thermal resistance, and incredible color options thanks to natural PETG being so clear. 

There are a few things to know before getting started, like the need for an all-metal hotend and the necessity of well-tuned retraction.

With PETG you can also take that ductility and use it in the design of some purposefully flexible geometry. Snap fit enclosures, where small tabs bend out of the way and snap into a channel once a lid is fully pressed in place, are a beautiful opportunity to utilize PETG. Or you can design a part that needs to rigidly hold something else without being too difficult to insert, like a bearing holder on a 3D printer part.
