PLA vs PLA+: What Actually Changes Between the Two

The short answer

PLA+ is not a standard: each brand blends its own formula and publishes its own settings, so compare one brand's PLA line against that same brand's PLA+ line instead of treating "PLA+" as a single material. Pay more for it when a part has to take impacts or flex without snapping. For display pieces, plain PLA does the job.

Nobody certifies the "plus". There is no ASTM or ISO grade called PLA+, so the label tells you only that the maker considers it an upgrade over its own regular PLA. Two spools that both say PLA+ on the box can need different nozzle temperatures and behave differently once printed.

What brands actually change

The names alone show how loose the category is. SUNLU, Overture, JAYO, Anycubic and eSUN sell lines called PLA+, ELEGOO and Duramic 3D call theirs PLA Plus, and ZIRO sells a PLA PRO line (opens in a new tab). The marketing goals differ too. SUNLU describes its version as "reinforced and toughened PLA" (opens in a new tab) that is less prone to breaking. Overture, by contrast, says its PLA+ is not built to maximize one feature (opens in a new tab) and instead pitches gains in print stability, layer adhesion, surface finish and structural strength.

When a brand publishes mechanical figures for both of its lines, you can see what the upgrade buys. Two brands do this on their product pages:

Read those rows carefully. In both brands the biggest jump is in impact or toughness figures, which is the property that decides whether a clip snaps when you drop it. Tensile strength moves far less, and Overture's own layer adhesion figure is essentially flat between the two lines. SUNLU's elongation is the same 10% for both, while Overture's quadruples. So "stronger" on a PLA+ box mostly means "less brittle", and how much less depends entirely on the brand.

Neither page names the test standard behind its numbers, so compare rows within a brand only. Setting SUNLU's impact figure beside Overture's toughness figure tells you nothing.

Published print settings, brand by brand

These are brands that sell both a regular PLA and a PLA+ line and publish a nozzle range for each on their own pages.

A few patterns stand out. Where the ranges differ, the PLA+ window tends to start equal or higher and reach a little further up, which fits a tougher blend that needs more heat to flow and bond. Anycubic is the exception that proves the point: its two lines share identical published temperatures, so whatever separates them is not in the print settings. JAYO's PLA+ even calls for a cooler bed than its regular PLA.

Inland and ELEGOO also sell both lines. Inland's manufacturer pages could not be read for this guide, so we have no verified figures for it. ELEGOO's pages list a ±0.02 mm diameter tolerance for both PLA (opens in a new tab) and PLA Plus (opens in a new tab), but we could not verify a temperature range for either, so they stay out of the table.

The spread across PLA+ products from different makers is wider than the gap inside any single brand. Duramic 3D (opens in a new tab) lists 210 to 230°C for its PLA Plus, while IIID MAX (opens in a new tab) lists 190 to 230°C and ZIRO's PLA PRO lists 190 to 220°C (opens in a new tab). A 20°C difference in minimum temperature between products sharing one label is exactly why the label alone cannot set your slicer profile. For tuning inside any of these windows, see our PLA print temperature guide.

When PLA+ earns its premium

• Parts that get dropped or knocked. Tool holders, cable clips, phone stands and anything that lives on a workbench benefit most from the higher impact figures above.
• Snap fits and thin clips. A tab that has to bend slightly before it locks is where brittle PLA tends to crack.
• Parts you will drill, screw into or tap. A less brittle plastic is less likely to split around a fastener.
• Prints you cannot easily reprint. Long jobs that would cost hours to repeat justify a small upgrade in toughness.

When plain PLA is the smarter buy

• Display models, miniatures, vases and props. They rarely see impact, and the extra spend adds nothing you will notice.
• Fit checks and prototypes. If a part is going to be revised next week, buy the cheaper spool.
• Anything near heat. PLA+ is still PLA based. Prusa's knowledge base notes that PLA gets soft and deforms above 60°C (opens in a new tab), and none of the PLA+ product pages cited here promise a fix for that. For a car dashboard or a part near a motor, read PLA vs PETG instead.
• Big multicolor jobs. If the toughness gain does not matter for the object, putting the savings toward more colors makes more sense.

Comparing price fairly

Spool sizes vary, so compare cost per kilogram rather than cost per spool. JAYO, for example, sells both of its lines as 1.1 kg rolls (opens in a new tab), which makes a per-spool price look higher than it is. On pla.deals, price per kg is the offer price divided by the total net filament weight across every spool in the listing, and spools of 250 g or less are labeled as samples and kept out of the cheapest lists. Each price shows when it was last verified against Amazon and switches to "Check price at Amazon" after 24 hours.

Finding a suitable spool

Open the filament finder, filter to PLA+ or to standard PLA, and sort by price per kg. Before you buy, check three things on the brand's own page: a published nozzle range your hotend covers comfortably, a stated diameter tolerance, and spool compatibility with any feeder you use. For example, eSUN ships PLA+ on a cardboard spool and offers a printable adapter (opens in a new tab) for Bambu Lab AMS users, while Anycubic lists its PLA+ as compatible with its ACE feeder (opens in a new tab). If two listings are close on price per kg, the one whose brand publishes mechanical data gives you more to go on.

Common mistakes

1. Assuming every PLA+ is interchangeable. A profile tuned for one brand can under-heat another by 20°C.
2. Running PLA+ at plain PLA temperatures. Starting eSUN PLA+ at 190°C puts you below its published 210°C minimum (opens in a new tab), which risks weak layer bonds and erases the toughness you paid for.
3. Comparing mechanical numbers across brands. Without a shared test method, cross-brand numbers are noise.
4. Expecting heat resistance. Tougher does not mean more heat tolerant.
5. Skipping drying. Anycubic recommends drying its PLA+ at 45 to 50°C for 6 to 8 hours (opens in a new tab) before use. Damp filament strings and prints weaker regardless of formula.
6. Trusting a single number on a page. Overture's PLA+ page gives a spec table range and a narrower FAQ recommendation of 200 to 220°C (opens in a new tab). When a page disagrees with itself, start where the two overlap.

Frequently asked questions

Is PLA+ stronger than PLA?

Usually tougher rather than stronger. The brands that publish both sets of figures show the biggest gains in impact and toughness, with smaller or no gains in tensile strength and layer adhesion. The size of the gain varies by brand.

Can any printer that handles PLA also print PLA+?

In most cases yes, since the published PLA+ ranges in this guide top out at 245°C and no enclosure is needed. Check that your hotend reaches the upper end of your chosen brand's range if you plan to print fast.

Are PLA Pro, PLA Plus and Tough PLA the same thing as PLA+?

They are all brand names for modified PLA, with no shared definition. Treat each as its own product and read its spec sheet.

Do I need new slicer settings when switching from PLA to PLA+?

At minimum, set the nozzle temperature from the new brand's published range and run a temperature tower. Retraction and cooling often carry over, but confirm with a small part first.
