PETG’s disadvantages


PETG filament can string easily due to its sticky nature. Some threads can stick out from the surface walls of the final product. PETG should not be used to print structures with intricate details or sharp parts.

Temperature issues

It has its low melting points, which can provide many benefits to users. However, there are also some drawbacks. It cannot be stored in temperatures higher than normal. It can cause the filament to react chemically with its container material, and thus ruin its properties.

Scratching is not recommended

PETG is a great filament due to its flexibility and outstanding impact resistance. However, PETG is more susceptible to scratching than other materials such as acrylic and glass. The printed product should be handled carefully and placed somewhere that is safe from sharp objects and children.

What is ABS?

ABS stands for Acrylonitrile Butadiene Styrene. It is a popular choice for 3D printers filaments. It is prepared using a base of petroleum followed by a variety of hydrocarbon monomers. This yellow-colored filament is easy to process and passes through the machine easily. You can learn a lot about another material. 3d printer PVA filament, as we’ve done on our PVA filament post.

Even before the creation of 3D printing technologyIt was already a popular plastic. It was first developed in the 1940s It gained momentum over the next ten years. Since then ABS has been used extensively to build a wide range of objects, including keyboards, medical devices and toys, as well as LEGO bricks.

ABS has many advantages


Products made from ABS plastic can last for a long time, if they are kept out of direct sunlight. You don’t have to worry about children or surrounding sharp objects ruining its appeal. ABS can withstand scratches and prevent the surface from getting damaged. It is also protected from wear and tear.


ABS is a strong material that can withstand high heat, stress, and pressure. ABS will bend instead of breaking when you apply pressure to it. ABS is a great material for making home appliances and automobile parts.

It is easy to do

ABS filaments don’t clog or jam the hot end while extruding in high temperatures. You can also use acetone to treat the ABS product surfaces. It can also be used to glue or trim off unnecessary sections. You can color it with any color acrylic paints to enhance its aesthetic appeal. This ABS plastic post also has additional features tips to easily cut ABS plastic.

You don’t have to break a bank or be a large enterprise to try out printing with ABS filaments. It’s a great option for small businesses and amateurs alike. You can buy a kilogram of ABS in a matter of minutes for less than twenty dollars. If you choose to settle for pellets, the price may go down even further.

ABS’s disadvantages

Temperature issues

ABS is not the best filament if you want to print a structure that has a large surface. ABS is susceptible to shrinkage, warping, curling, and warping during 3D printing.

After printing is completed, it is important to monitor the cooling process. Overcooling the surface can cause cracks. We recommend using a 3D printer With an enclosure.

Printing Odor

You should make sure that the windows and ventilators are open. working with ABS filaments. This material can emit a foul odor when it is printed on 3D objects. Even after the job is finished, the stench from used ABS filament can remain for a while.

Environmental Damage

ABS is unfortunately not available. not an environment-friendly 3D filament. It is biodegradable, and made from non-renewable resources like oil.

It can be recycled, but this will lead to a lot of waste and energy consumption. ABS is not recommended if you care about the environment.
