This filament has the strength and flexibility of ABS, while keeping the printing process as simple as when we're using PLA. It’s highly versatile, adaptable and can be used for a wide variety of purposes.

Pros
Pro Can safely be used for applications where it comes in contact with food
This filament can safely be used to create e food and drink containers or parts for food production lines (like conveyor belt parts, for example ), unlike ABS, PLA or other popular 3D printing filament materials. PETG filament is food safe, as there are no potential hazards to food or human body while in contact with this material. In fact, PETG is a modified version of PET, which is a material widely used for food packaging.
Pro Simultaneously strong and flexible
PETG is pretty much as strong as ABS (in terms of direct load) and nearly as flexible as PLA, combining the best characteristics of these two materials. On top of that, printing PETG is easier than printing ABS, since it does not require a heated bed and has better layer adhesion.
Cons
Con Finding the perfect setting takes some time and effort
While this filament is easy to print, getting to the "optimal results" level requires extra work. Because temperatures vary within the extruder used, finding the perfect printer settings will, most likely, take several attempts.
Con Material specifications sheet available only upon request
The material specifications sheet isn't publicly available, but it is possible to request it from regional eSUN distributors. This is a hassle mostly for engineers and those in the academia, who will surely need this, since they will have no choice apart from spending some time and effort to get the specifications sheet. It would be better to have the specs available from the get-go.
