PETG Vs. PLA Filament

Regarding choosing a 3D printing material, some factors impact hobbyist decision, and mostly it comes down to its strength and printability. The hobbyist's most common and used filaments are PLA and PETG filaments. Each of these filaments has different strengths, printability, and many more. But each difference makes it suitable for a specific application and making process. So let's talk about PETG filament vs. PLA filament.

  1. PETG Vs. PLA Filament Regarding choosing a 3D printing material, some factors impact hobbyist decision, and mostly it comes down to its strength and printability. The hobbyist's most common and used filaments are PLA and PETG filaments. Each of these filaments has different strengths, printability, and many more. But each difference makes it suitable for a specific application and making process. So let's talk about PETG filament vs. PLA filament. PLA filament Polylactic acid (PLA) filament is the most popular filament material in FDM 3D printing and is most commonly used in food-grade models because of its eco-friendliness. It is extracted and purified from corn grain; the starch is removed and mixed with special food-grade chemicals. Then it is either condensed or polymerized to produce the raw PLA plastic. PLA can support an array of printing applications, it is both low-warping and odorless, and most interestingly, it does not require a heated bed. It requires less energy compared to traditional or other filaments. Additionally, PLA filament lacks strength compared to other filaments. PLA 3D filament properties include; Bubble free hence a high-quality model. Clog free hence smooth extrusion Eco-friendly since it is made from corn grain. Less cracking problem. It is best for beginners since it is easy to print on and is known for less warping. PETG filament

  2. Polyethylene terephthalate glycol-modified (PETG) is also another famous 3D printer filament. It is an upgraded version of PET, where the difference only lies on the ‘G’ standing for glycol upgrade that is known to lower the melting point of PETG hence making it easier to print on. The chemical components of terephthalic acid and ethylene glycol are extracted from oil, which is heated and mixed to produce raw PETG plastic. Of course, being extracted from oil makes it not so friendly to the environment, but note that some recycling centers accept PETG; this shows that it isn't hazardous to the environment. PETG is known to be durable, has strength, and PETG density offers an even more significant advantage in printability. Its specifications include; It is chemical resistant and even tolerant to an array of chemicals It is heat resistant and noticeably durable with high flexibility, the flexural modulus of 2050 / MPa; it is also highly rigid. These specifications show that PETG is ideal for printing 3D models that will exist under harsh weather, with many application options.
