Comparing PETG vs PLA: What Is the Difference and Which Filament Is Better for You?

Whether you are a newbie or an advanced user in the world of 3D printing adventures, it’s always fun to learn more about the materials you can use for creating a true masterpiece. Let’s look at PETG vs PLA, some of the most popular filament types today for making figures and models. What is the difference between the two materials? Which one is stronger? Which one is more flexible? Answering these questions will help you decide when it’s best to use one type and when it’s better to switch to the other.

Gambody enthusiasts love printing and painting PETG, PLA, and other filaments. We’ll show you some impressive photos of their projects that showcase the difference between PLA and PETG better than words can. Understanding all the tricks can improve your own models and make you so much happier!

PETG VS PLA

PLA, PETG are filaments used by 3D printing enthusiasts, newbies & experts alike. Each material brings its own flair to your project, making it unique, beautiful, and impressive.

PLA stands for Polylactic Acid. PETG stands for Polyethylene Terephthalate Glycol. When you look at the spools, you might think they are similar. However, these filaments are different and can elevate your experience to a new level once you master their properties and understand the PLA vs PETG usage advantages for yourself.

What Is PETG Filament?

PETG filament is made from PET (Polyethylene Terephthalate) with the addition of glycol, making it fully recyclable. Just like PET, PETG is a durable and strong 3D printing material that can be used for functional parts.

What Is PLA Filament?

PLA is made from renewable resources, such as corn starch, cassava roots, and sugarcane. It is biodegradable under certain industrial conditions. This eco-friendly thermoplastic polyester is highly popular in the 3D printing world. It is perfect for making collectible figures and models to display on your shelf since it adds a lovely polished finish.

Is PETG Stronger than PLA?

PETG is indeed stronger than PLA filament. Its flexibility, durability, and strength make it ideal for building functional objects, such as clips, hinges, and outdoor parts. PLA is less flexible and more prone to breaking.

Difference Between PLA and PETG

In terms of pricing, PETG vs PLA are pretty similar. You can find a spool of these filaments for $12 to $13 or pay slightly over $20 for a pack of two. Prices depend more on colors than on the filament type. Unique options, such as changeable and metallic colors, tend to cost more than regular black, white, and single-shade ones.

If your printer doesn’t have a heated bed, it’s best to go with PLA because it works in lower temperatures of 55 °C to 60 °C (for the bed) and can “survive” printing at room temperature (nozzle temperature has to be between 190 °C and 220 °C). Users who want to use PETG will have to heat the bed up to 90 °C and set the nozzle temperature to approximately 240 °C to 260 °C. Besides, this material can release fumes, so good ventilation is required. However, it’s best to adjust the temperatures by brand.

The PETG vs PLA debate is ongoing. Some users prefer using PLA, which is much easier to prepare for painting, while others enjoy working with PETG. It’s absolutely up to your personal tastes and decisions. Experimenting with various materials is probably the best solution, as it lets you find the types of materials and brands you love most.

Painting PETG

This type of 3D printing material is heat-resistant. It requires higher nozzle and bed heat temperatures, but if you overheat it, you can deform it and ruin your project. Thus, when you sand and smooth the PETG surfaces, you should be extra careful.

If you use supports, space them from the model parts by 0.5 mm or more to avoid damaging your project’s structure when removing the supports from a PETG project.

Painting PLA

PLA’s melting point is lower than PETG’s. It’s much easier to sand and prepare for painting, which makes it one of the most popular 3D printing materials among hobbyists with FDM/FFF printers. When comparing PLA vs PETG, most newbies choose PLA because it is super easy to use and user-friendly.

FAQ

Is PETG more flexible than PLA?

Yes, it is. It is more impact-resistant and will bend rather than break.

Is PETG biodegradable?

No, it is not. This material can be recycled, but it is not biodegradable.

What is the difference between PLA and PETG?

Both Polylactic Acid and Polyethylene Terephthalate Glycol are 3D printing materials used by FDM/FFF printers. The first one is extremely popular for making figures and models for displaying in your room, office, or backyard. The second one is stronger and more flexible, and can be perfect for functional parts to hold your shelves, etc. In terms of possibility of printing clear parts, both types of filaments offer such an option. You can find translucent PLA and transparent PETG from numerous brands.
