PLA+ vs Regular PLA: Is the Upgrade Worth It?

PLA+ (also called PLA Pro or Tough PLA by some brands) is marketed as a stronger, better version of regular PLA. But is it actually worth the extra cost? After printing with both materials extensively, I can give you a nuanced answer: it depends on what you are printing.

This guide breaks down the real differences between PLA and PLA+ so you can make an informed decision for your projects.

What Is PLA+?

Standard PLA (polylactic acid) is a biodegradable thermoplastic made from renewable resources like corn starch or sugarcane. It is the most popular 3D printing filament because it is easy to print, widely available, and produces good-looking parts.

PLA+ is regular PLA modified with additives that improve specific properties. The exact formulation varies by brand — there is no universal standard for what "PLA+" means. Generally, manufacturers add impact modifiers, plasticizers, or other polymers to address PLA's biggest weakness: brittleness.

Some brands call their enhanced PLA different names:

• eSUN: PLA+
• Polymaker: PolyTough PLA / PolyMax PLA
• Overture: PLA Pro
• Bambu Lab: PLA Basic (their standard PLA already has some enhancements)

The lack of standardization means PLA+ from one brand might perform very differently from another. I will focus on the general trends.

Strength and Toughness

This is the main selling point of PLA+, and it is real.

Regular PLA is strong but brittle. It handles static loads well (holding weight on a shelf bracket, for example) but shatters when hit or dropped. If you have ever snapped a PLA print by flexing it, you know exactly what I mean. The break is sudden and clean, like glass.

PLA+ is measurably tougher. The impact modifiers give it more ductility, meaning it deforms before breaking instead of shattering. This makes a significant difference for:

• Parts that might be dropped (phone cases, tool holders)
• Parts under dynamic loads (clips, hinges, snap-fits)
• Parts that flex repeatedly (cable clips, bag clips)

In practical testing, PLA+ parts typically survive drops and impacts that would shatter regular PLA. The difference is not subtle — it is immediately noticeable.

However, the raw tensile strength (how much force before it breaks when pulled) is similar between PLA and PLA+. The difference is in how they break, not when they break.

Print Quality

Regular PLA prints beautifully. Crisp edges, smooth surfaces, minimal stringing, excellent bridging. It is the gold standard for print quality.

PLA+ prints almost as well, but there are minor differences:

• Slightly more stringing in some brands
• Sometimes glossier surface finish (can be a pro or con depending on your preference)
• Bridging performance is comparable to PLA
• Overhangs perform similarly

The print quality difference is small enough that most people would not notice unless comparing side by side.

Temperature and Settings

| Property | PLA | PLA+ | |----------|-----|------| | Nozzle temperature | 190-220°C | 200-230°C | | Bed temperature | 50-60°C | 55-65°C | | Print speed | 40-100 mm/s | 40-100 mm/s | | Cooling | 100% after first layer | 100% after first layer | | Heat resistance | ~55°C | ~58°C |

PLA+ generally wants slightly higher temperatures for best layer adhesion. This makes sense because the additives change the flow characteristics slightly.

The heat resistance improvement is minimal. Neither PLA nor PLA+ should be used in high-temperature environments. Both will deform in a hot car or near a heat source. If you need heat resistance, look at PETG, ABS, or annealed PLA.

Cost Comparison

PLA+ typically costs 15-30% more than regular PLA from the same brand. Here is a rough comparison:

• Budget PLA: $15-18 per kg (Hatchbox PLA)
• PLA+: $18-24 per kg (eSUN PLA+)
• Premium PLA+: $25-35 per kg (Polymaker PolyMax PLA)

The price difference is significant when you are going through multiple rolls per month, but negligible for occasional printing. A single roll lasts most hobbyists weeks.

When to Use PLA+

Based on my experience, here is when PLA+ is worth the upgrade:

Use PLA+ for:

• Functional parts that bear loads or experience impacts (brackets, clips, mounts)
• Parts with snap-fit connections that need to flex without breaking
• Items that might be dropped (phone stands, portable tools)
• Parts with thin walls that would be fragile in regular PLA
• Anything going to someone else as a gift (the extra durability means it lasts)

Stick with regular PLA for:

• Decorative items (vases, figurines, lithophanes)
• Articulated and print-in-place models (regular PLA's sharp printing characteristics are better for tight tolerances)
• Prototypes and test prints
• Large prints where material cost matters
• Items that will not experience impacts or dynamic loads

Brand Recommendations

Not all PLA+ is created equal. Here are the brands I have had the best results with:

eSUN PLA+ — The most popular PLA+ on the market. Good strength improvement over regular PLA, prints easily, available in many colors, and priced reasonably. This is my default recommendation.

Polymaker PolyMax PLA — Premium option with the best impact resistance of any PLA variant I have tested. Prints beautifully. Worth it for critical functional parts. Their technical data backs up the performance claims.

Overture PLA Pro — Budget-friendly option that provides a noticeable improvement over standard PLA. Good value for the price.

For regular PLA, Hatchbox PLA remains my go-to for its consistency and wide color selection.

My Testing Experience

I have been doing informal strength tests on PLA vs PLA+ parts for a while. The most telling test is simple: print a 2mm-thick test bar, hold it in two hands, and flex it until it breaks.

Regular PLA snaps cleanly with a sharp crack. The break is brittle, like snapping a dry twig.

PLA+ bends first. You can see it deforming before it finally breaks. It absorbs significantly more energy before failure, which is what "toughness" means in materials science.

For real-world applications, this translates to parts that survive being dropped off a desk, clips that do not shatter when you flex them open, and tool holders that absorb the impact of throwing a wrench back into them.

The Verdict

PLA+ is a genuine improvement over regular PLA for functional parts. The toughness upgrade is real and meaningful. But it is not a miracle material — it is still PLA at its core, with similar heat resistance and UV limitations.

For functional prints where durability matters, PLA+ is worth the 15-30% price premium. For decorative prints, prototypes, and models where appearance matters more than toughness, regular PLA is the better choice.

My recommendation: keep a roll of each on hand. Use regular PLA as your default, and switch to PLA+ when strength matters. Both are available in plenty of colors, and the settings are similar enough that switching between them takes minimal adjustment.

Find Models to Test With

Want to print some functional parts to see the difference for yourself? Use 3DSearch to find functional models across Printables, Thingiverse, and MakerWorld. Try printing the same model in both PLA and PLA+ and compare. A bag clip, phone stand, or carabiner would be perfect test subjects.
