Choosing the right filament for your 3D printing projects is often one of the most important steps to getting the best result. If you’re a beginner in 3D printing, the choices can be quite confusing.

We’ll explore why PLA filaments are a good choice to start with, and how they compare with other common materials like ABS and PETG.

What is PLA (Polylactic Acid)?

Definition and Components of PLA Filament

So, what is PLA filament? PLA (Polylactic Acid) is a thermoplastic made from renewable resources like cornstarch, making it an eco-friendly choice for 3D printing. 

This filament has become one of the most widely used materials due to its easy-to-use properties and versatility. PLA filament typically requires lower extrusion temperatures than other filaments (between 180–200°C), which makes it well-suited for beginner printers as it is easier to use. Our Geeetech filament is particularly noted for its smooth printing experience, avoiding common issues like clogging the extruder. Additionally, Geeetech offers a variety of PLA filament types beyond the standard: high-speed PLA, luminous PLA, and even creative options like silk and marble PLA. There is also clear PLA filament for projects needing transparency.

Is PLA Actually Plastic?

Yes, PLA is indeed a type of plastic, but not your typical kind.
PLA is biodegradable and derived from renewable biomass, meaning it’s less harmful to the environment compared to other filament types. Though it is still plastic, PLA’s nature makes it a more environmentally-conscious 3D printing material.

What Will Dissolve PLA?

When you smooth the surface of your PLA prints for painting, you have to choose a good chemical. Using ethyl acetate is a good choice for PLA. It helps to dissolve the surface slightly, making it smoother and easier to prepare for painting, without damaging the main structure. Another option you may have around isopropyl alcohol (IPA), which, while not as effective as ethyl acetate, can still be used for minor smoothing.

Note also that PLA is resistant to water and won’t dissolve simply by soaking in water, unlike some other printing materials.

How Long Does PLA Prints Last?

PLA prints are durable under typical indoor conditions. However, exposure to sunlight and moisture can degrade the material over time, causing it to become brittle. Therefore, it is not recommended for outdoor projects. Proper storage in a cool, dry place is also essential for longevity.

Advantages and Disadvantages: PLA vs ABS

To choose PLA or ABS filament, you should look at the different needs of your project.

Advantages of PLA

• Lower printing temperature
• Minimal odor while printing
• Eco-friendly, biodegradable material
• Great for detailed and decorative items

Disadvantages of PLA

• Limited resistance to heat and UV exposure
• More brittle compared to ABS

Advantages of ABS

• More durable and heat-resistant
• Ideal for mechanical parts and outdoor use

Disadvantages of ABS

• Emits fumes when heated, requiring good ventilation during printing

Choosing between PLA vs ABS filament comes down to project needs: PLA is typically the best 3D filament for ease and aesthetics, while ABS generally works best for projects needing durability and strength.

Printing Tips for Beginners and Pros

How to Set up Your 3D Printer?

Before you start a print, you must set up your printer properly. Ensure that your slicer settings are configured for the specific filament you are using. For Geeetech PLA filament, you can use a bed temperature between 50–60°C. Also, calibrate your extruder temperature (typically between 180–200°C for PLA) and make sure your print bed is level.

How to Choose PLA, ABS, or PETG for Projects?

Each filament type has its strengths and weaknesses, which makes them suitable for different kinds of projects.

• PLA: Best for beginners, decorative objects, and items not exposed to heat.
• ABS: Ideal for mechanical parts and outdoor use due to its heat resistance.

PETG: A middle ground between PLA and ABS. PETG is strong, UV resistant, and easier to print than ABS. Choosing between PETG filament vs PLA often comes down to durability vs ease of printing.

How to Store Filaments?

How to Dry Filament

Moisture can cause serious printing issues, like poor layer adhesion and bubbling. You can dry your filament using a filament dryer box or simply place it in an oven at a low temperature for a couple of hours. 

How to Keep Filament Dry More Properly

For a more ‘appropriate’ way to store filament, you can use vacuum storage bags to keep the filaments dry and maintain their quality. Geeetech offers thickened vacuum bag sets that are ideal for this purpose, which will help you get the best performance out of your filaments over time.

Popular Applications of 3D Printing

Various Industry Applications

PLA filament and other 3D printing materials have been gaining traction. From rapid prototyping in the electronics sector to creating custom parts in electric vehicles, the potential uses are rapidly escalating.

On a more personal level, 3D printing has also made its way into daily life, providing practical solutions for household issues. For example, a 3D-printed knife shelf board can be a clever replacement when traditional wooden boards become moldy, as I have done.

With its vibrant colors, smooth finish, and ease of printing, Geeetech PLA filament is perfect for printing aesthetically pleasing items such as figurines, home decor, or even educational tools.

How Can You Start A Business with 3D Printing?

Starting a 3D printing business has become more accessible than ever, thanks to affordable printer models and versatile filament availability. Whether it’s producing custom phone cases, jewelry, or even cosplay items, you can use Geeetech PLA filament to create high-quality, visually stunning products.

What Kind of Primer Is Good for PLA Filament?

Priming your PLA prints is smart if you plan to paint them. Spray primers work well, and make sure to choose a primer that adheres well to plastic. Light sanding before priming also helps the paint stick better, providing a smoother final product.

Final Decision

PLA filament is an excellent all-around choice for beginners and experts alike, offering ease of use, eco-friendly attributes, and a vibrant range of colors for creative projects. When weighing PLA vs ABS filament or PETG filament vs PLA, consider what properties you prioritize—whether it’s ease of use, strength, or versatility.

With Geeetech’s variety of PLA options, you can find the best 3D filament that suits your printing needs, bringing your creative visions to life.
