PLA vs PLA+: Which 3D Printer Filament Should You Choose?

Choosing the right filament is one of the most important decisions for successful 3D printing.

For beginners, PLA and PLA+ are two of the most popular 3D printer filaments because they are easy to print, widely compatible, and suitable for a variety of projects.

But what is the difference between PLA and PLA+?

Is PLA+ really better than PLA?

And which filament is the best choice for your 3D printing projects?

In this guide, we will compare PLA vs PLA+ in detail, including strength, print quality, ease of use, applications, and how to choose the right filament for your needs.

What Is PLA Filament?

PLA (Polylactic Acid) is one of the most commonly used materials in 3D printing.

It is made from renewable resources such as corn starch or sugarcane and is known for its excellent printability.

Because PLA requires relatively low printing temperatures and has minimal warping, it has become the first filament choice for many beginners.

Advantages of PLA Filament

Easy to Print

PLA works well with almost all FDM 3D printers.

It usually requires:

• Lower nozzle temperature
• Lower bed temperature
• Less calibration

This makes PLA ideal for beginners who are learning 3D printing.

Excellent Surface Quality

PLA produces:

• Smooth surfaces
• Sharp details
• Clean edges

It is widely used for:

• Decorative models
• Miniatures
• Educational projects
• Display objects

Wide Color Selection

PLA filament is available in many colors and special finishes, including:

• Matte PLA
• Silk PLA
• Rainbow PLA
• Metallic PLA

This makes it popular among creators who focus on appearance.

What Is PLA+ Filament?

PLA+ is an upgraded version of traditional PLA.

Manufacturers improve PLA+ by adding modified materials and improving the polymer formula.

The goal is to maintain PLA's easy printing characteristics while improving mechanical performance.

Advantages of PLA+

Higher Strength and Toughness

Compared with standard PLA, PLA+ usually provides:

• Better impact resistance
• Improved layer adhesion
• Higher durability

This makes PLA+ more suitable for functional parts that need additional strength.

Better Layer Bonding

PLA+ creates stronger connections between printed layers.

This helps reduce:

• Cracking
• Breaking under stress
• Weak points in models

More Functional Applications

PLA+ is suitable for:

• Engineering prototypes
• Tool holders
• Mechanical parts
• RC accessories
• Daily-use objects

PLA vs PLA+: Key Differences

Strength Comparison: PLA vs PLA+

The biggest difference between PLA and PLA+ is mechanical performance.

Standard PLA is rigid but can become brittle when exposed to impact.

For example:

A PLA model may look perfect but break when dropped or under repeated pressure.

PLA+ improves flexibility and toughness, making printed parts more resistant to daily use.

For projects that require durability, PLA+ is usually the better choice.

Print Quality Comparison

Both PLA and PLA+ can produce excellent print results.

However:

PLA is often preferred for:

• Detailed models
• Decorative objects
• Art projects

PLA+ is preferred for:

• Functional designs
• Moving parts
• Prototypes

The final print quality also depends on:

• Printer settings
• Printing temperature
• Printing speed
• Filament quality

Which Filament Should Beginners Choose?

If you are new to 3D printing, both PLA and PLA+ are great choices.

Choose PLA If You Want:

✓ The easiest printing experience
✓ Beautiful visual models
✓ Decorative projects
✓ Low-cost experimentation

Recommended projects:

• Figures
• Decorations
• School models
• Desk accessories

Choose PLA+ If You Want:

✓ Stronger prints
✓ More durable models
✓ Functional designs
✓ Long-lasting parts

Recommended projects:

• Phone holders
• Tool organizers
• RC parts
• Mechanical components
• STEM projects

PLA vs PLA+: Which One Is Better for 3D Printing Projects?

There is no single “best” filament.

The right choice depends on your project.

For Students and Education

Recommended:

PLA / PLA+

Why?

Students can quickly print:

• Geography models
• Science demonstrations
• Engineering prototypes
• Classroom projects

PLA is easier for simple learning projects, while PLA+ is better for repeated testing.

For Makers and Hobbyists

Recommended:

PLA+

Makers often need parts that can survive:

• Assembly
• Movement
• Testing
• Daily use

PLA+ provides a better balance between print quality and durability.

For Functional Parts

Recommended:

PLA+

Examples:

• Brackets
• Storage organizers
• Mechanical components
• Custom tools

The improved toughness helps parts last longer.

How to Get Better PLA and PLA+ Printing Results

Even the best filament needs proper storage and settings.

1. Keep Filament Dry

Moisture can cause:

• Stringing
• Bubbles
• Poor surface quality
• Weak prints

Store filament in:

• Sealed bags
• Dry boxes
• Filament storage containers

2. Adjust Printing Temperature

Different filaments may require different settings.

Always check recommended:

• Nozzle temperature
• Bed temperature
• Printing speed

3. Use Quality Filament

High-quality filament provides:

• Consistent diameter
• Stable extrusion
• Better printing results

This reduces failed prints and improves reliability.

Final Recommendation: PLA or PLA+?

For beginners and everyday printing:

PLA is an excellent starting point.

For users who want stronger, more durable, and more functional prints:

PLA+ is the better upgrade.

A simple rule:

Choose PLA for creativity.

Choose PLA+ for performance.
