PETG vs ABS Filament - Which One Provides a Better Surface Finish?
As 3D printing enthusiasts, we are constantly on the lookout for the best filament to achieve high-quality prints. One of the significant factors in achieving a good print is the surface finish. In this blog post, we will compare PETG and ABS filaments in terms of surface finish quality. So, let's dive into the comparison!
PETG Filament
PETG (Polyethylene Terephthalate Glycol) is a thermoplastic polymer that possesses excellent strength, durability, and flexibility. It is derived from PET, the same plastic material used in water bottles. PETG's properties make it an excellent material for 3D printing applications. It melts at a temperature of around 220°C to 250°C, depending on the brand, printer, and nozzle size used.
Surface Finish Quality
PETG filament provides a decent surface finish, and the print is more translucent than ABS. PETG's surface has a slight sheen, which adds a semi-glossy appearance to the surface. However, PETG does not have a glossy finish, and it does not achieve a mirror-like finish like some filaments such as PLA or Nylon.
ABS Filament
ABS (Acrylonitrile Butadiene Styrene) is another popular thermoplastic polymer used in 3D printing. ABS is strong and durable, resistant to heat, and has a smooth surface. ABS has high stiffness and strength, making it an ideal material for automotive parts, toys, and electronic housings. ABS melts at a temperature of around 230°C to 250°C, depending on the brand, printer, and nozzle size used.
Surface Finish Quality
ABS provides a smooth surface finish, but it requires post-processing to achieve a glossier finish. One of the main reasons for this is that ABS is prone to warping, and it is challenging to achieve full bonding between layers. Additionally, ABS has a visible striation pattern, and the surface is not as translucent as PETG.
Which One Provides a Better Surface Finish?
Both PETG and ABS provide decent surface finish quality, but it ultimately depends on the type of the print you want to create. If you're looking for a part with high stiffness and excellent durability that does not require a glossy finish or post-processing, ABS is the best choice. On the other hand, if you want a more translucent and glossy finish, PETG would be the better choice.
In summary, PETG provides a semi-glossy surface finish suitable for printing translucent objects, whereas ABS is better suited for creating objects requiring high strength, stiffness, and durability.
We hope this comparison has been helpful in choosing the right filament for your next 3D printing project. Remember to consider the specific properties of the filament and the type of the print you wish to create for the best results.
