Add to SafariWhen comparing eSUN PETG Filament vs Proto-pasta Original Carbon Fiber Filament, the Slant community recommends Proto-pasta Original Carbon Fiber Filament for most people. In the question“What are the best filaments for 3D printing?” Proto-pasta Original Carbon Fiber Filament is ranked 7th while eSUN PETG Filament is ranked 8th. The most important reason people chose Proto-pasta Original Carbon Fiber Filament is:
This filament's resulting prints are very stiff and can withstand great stresses, perfect for when you need extra strength in your projects. This is due to the carbon fibers used in this filament, which are small enough to make it through the printing nozzle, but long enough to add rigidity.

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.
Pro Can be used with nearly every 3D printer
This filament is available for both 1.75 mm and 3.0 mm extruders. It also does not require a heating bed when printing, although it’s better if you have one. It can also be printed using standard brass nozzles.
Pro Printed objects are very stiff and strong
This filament's resulting prints are very stiff and can withstand great stresses, perfect for when you need extra strength in your projects. This is due to the carbon fibers used in this filament, which are small enough to make it through the printing nozzle, but long enough to add rigidity.
Pro Allows to 3D print objects that can't usually be 3D printed
The extreme rigidity and stiffness of this material enables the user to print things that normally can't be properly 3D printed. It’s great for printing frames, supports, shells, propellers and even tools. All these applications are interesting for users that are drone builders, RC hobbyists, or similar.
Cons
Con Filament packaging provides proper protection
The material comes in a spool packed inside a vacuum film, with an included desiccant. All this is packaged inside a tough cardboard box, which keeps everything safe during shipping and storage.
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.
Con Requires some skill to use
Since this filament contains tiny carbon fibers, it’s difficult to print with standard extruders. Adjusting the correct feed rate and printing temperature specifically for your extruder will be necessary. Note that it is also recommended to use stainless steel nozzles while printing this material, since it has been reported that regular brass nozzles may deform while printing this material.
Con Only available in black
Because it contains carbon fibers, the filament is only available in black.
Con Can only be used with 1.75 mm nozzles
The filament is only available in 1.75 mm diameter, meaning it can't be used with printers that have nozzles with different diameters.
Con No available datasheet with mechanical data
The lack of technical documentation makes this product almost unusable for academics and professional engineers, due to the need of having the exact mechanical values in order to justify design decisions.
