​PLA Filament: The Beginner's Guide to 3D Printing with High-Quality Plastic

When it comes to 3D printing, choosing the right filament material is essential. PLA filament has become the most popular choice for 3D printing enthusiasts and professionals alike. PLA filament is a biodegradable and eco-friendly option made of plant-based materials like cornstarch. In this beginner's guide, we will dive deeper into the world of PLA filament and explore its properties, uses and advantages.

What is PLA filament?

PLA filament is a thermoplastic polymer that is made from renewable resources such as cornstarch, tapioca roots, or sugarcane. It is a type of plastic material that is biodegradable and compostable, making it an eco-friendly option for 3D printing. PLA filament can come in a variety of colors, but most commonly, it is translucent with a shiny finish.

Why choose PLA filament?

There are many reasons why PLA filament is the preferred choice for 3D printing enthusiasts. Firstly, it is easy to work with, and the printing process requires minimal setup. Secondly, PLA filament is a cost-effective solution when compared to other 3D printing materials such as ABS or Nylon. Thirdly, PLA filament is environment friendly and biodegradable. Furthermore, PLA filament produces less odor during printing than other materials, making it the healthier choice for indoor use.

How does PLA filament work?

PLA filament is a thermoplastic material, meaning it can be heated and molded multiple times without deterioration. A 3D printer with a PLA filament extruder will heat the filament and push it through an extruder nozzle that is moved around by the printer software. The nozzle deposits melted PLA filament onto the printing bed, layer by layer, building up the object you have designed.

What is the printing temperature for PLA filament?

The recommended printing temperature for PLA filament is typically between 180°C and 220°C. However, different brands of PLA filament may have slightly different optimal temperatures, so it's always best to check the manufacturer's guidelines. If the temperature is too high, or the printing speed is too fast, the PLA filament may not stick to the bed, and the final product may not be accurate. Spool3D PLA filament prints best at 210-215°C.

What are the advantages of PLA filament?

PLA filament has several advantages over other 3D printing materials. Firstly, it is biodegradable and eco-friendly. Secondly, it is easy to work with as it does not require a heated bed or an enclosed printing area. Thirdly, it produces a lower carbon footprint compared to other materials, and it is recyclable. Fourthly, it does not produce contaminants, making it safe for indoor use.

What are the limitations of PLA filament?

While PLA filament has many advantages, it also has some limitations. Firstly, it is not very durable and can be brittle, meaning it may crack under impact. Secondly, it is not suitable for high-temperature applications as it has a low melting point. Thirdly, it is not resistant to chemicals and solvents, meaning it is not suitable for some industrial applications.


To conclude, PLA filament is a great choice for 3D printing enthusiasts who want a biodegradable and eco-friendly option that is easy to work with. It is cost-effective, produces less odor, and can produce high-quality prints with minimal setup. While it has some limitations, the benefits of PLA filament outweigh the negatives. Whether you are a hobbyist or a professional, adding PLA filament to your 3D printing collection is a wise investment.
