Best PLA+ Filament Brands 2026

PLA+ (PLA Plus) is standard PLA improved with rubber-toughening additives — better layer adhesion, higher impact resistance, less brittleness. You get most of PLA's easy printability but with parts that actually survive real use.

We ranked the top PLA+ brands by impact resistance (notched Izod kJ/m²), diameter consistency, print quality, and value. Here's the definitive 2026 list.

⚡ Quick Picks

Best value: eSUN ePLA+ — cheapest, most consistent, 60+ colors
Toughest: Polymaker PolyMax PLA — 47% more impact-resistant than eSUN
Bambu printers: Bambu Lab PLA Basic — optimized for AMS, 0.02 mm tolerance
Budget high-volume: SUNLU PLA+ — available in 4 kg bulk packs

PLA vs PLA+: What's the Actual Difference?

"PLA+" is not a standardized name — manufacturers use it for PLA blended with impact modifiers (typically rubber, polyurethane, or proprietary additives). There's no universal formula. What you actually get:

Property	Standard PLA	PLA+
Impact resistance	~2–3 kJ/m²	4–8 kJ/m² (+50–200%)
Tensile strength	~55–60 MPa	~50–65 MPa (similar)
Layer adhesion	Good	Better (+15–25%)
Brittleness	High — snaps on drops	Lower — flexes before breaking
Print temp	190–220 °C	210–235 °C (slightly higher)
Heat resistance	55–60 °C HDT	~55–65 °C HDT (similar)
Surface finish	Slightly shinier	Slightly more matte
Price	$15–25/kg	$18–30/kg (+10–25%)

Key takeaway: PLA+ doesn't beat PLA on every metric. It's not stiffer, not more heat-resistant. The improvement is specifically in impact resistance and layer bonding — what matters for functional prints.

Bambu's PLA Basic is a toughened PLA variant with consistent 0.02 mm diameter tolerance — critical for AMS multi-material printing. Dries fast. Not the cheapest but zero-headache on Bambu hardware.

4
Hatchbox PLA+
8.5/10$

Best forBudget pick — USA warehouse

Impact resistancenotched Izod 4.1 kJ/m²

Print temp / Bed210–230 °C / 50–60 °C

Fast Amazon shipping, reliable batch-to-batch consistency. Impact resistance slightly below eSUN PLA+ but solid for decorative-functional parts. Great starter pick.

5
SUNLU PLA+
8.1/10$

Best forHigh volume / cost-sensitive

Impact resistancenotched Izod 3.8 kJ/m²

Print temp / Bed210–230 °C / 50–60 °C

Good consistency for the price. Slight batch variation compared to eSUN. Works well for large prints where you need many spools. 4 kg packs available.

PLA+ Print Settings Guide

PLA+ needs slightly different settings than standard PLA. Use these as a starting baseline and tune from there:

Setting	Standard PLA	PLA+	Note
Nozzle temp	195–215 °C	215–230 °C	Start at 220 °C
Bed temp	45–55 °C	50–65 °C	PEI works well
Cooling fan	80–100%	50–80%	Less cooling = better layer bond
Print speed	40–80 mm/s	40–70 mm/s	Slightly slower for best adhesion
Layer height	0.1–0.3 mm	0.15–0.3 mm	0.2 mm sweet spot
Retraction (direct)	0.5–1 mm	0.5–1 mm	Same as PLA
Retraction (Bowden)	4–6 mm	4–6 mm	Same as PLA
Infill	15–20% decorative	30–50% functional	Use gyroid for impact resistance

⚡ Pro tip: reduce cooling for functional parts

The toughness of PLA+ comes from layer-to-layer fusion. Dropping cooling fan to 50% (vs 100% for decorative PLA) significantly increases inter-layer strength. Trade-off: slightly less sharp overhangs. Worth it for anything load-bearing.

PLA+ vs Other Materials: When to Choose What

Use case	Best choice	Why
Functional brackets, clips, enclosures	PLA+	Better impact resistance than PLA, easier than PETG
Parts exposed to heat (>60 °C)	PETG or ABS	PLA+ softens at 55–65 °C, not suitable
Flexible/snap-fit parts	TPU	PLA+ snaps, TPU flexes repeatedly
High-detail miniatures/figurines	Standard PLA	PLA has sharper bridging with 100% cooling
Mechanical parts — gears, housings	Nylon or PETG	Wear resistance not PLA+'s strength
Outdoor use (UV/moisture)	ASA or PETG	PLA+ degrades in UV and moisture
Everyday functional prints	PLA+	Best balance of printability + toughness

FAQ — PLA+ Filament

Is PLA+ stronger than regular PLA?

In impact resistance and layer adhesion — yes. PLA+ is 15–30% tougher in impact tests (notched Izod) and less prone to snapping under sudden loads. Tensile strength is similar. PLA+ is not stiffer or harder than standard PLA — those values are actually very similar.

What temperature should I print PLA+?

Most PLA+ brands print best at 215–230 °C nozzle and 50–60 °C bed. Start at 220 °C and adjust ±5 °C based on stringing (lower) or layer adhesion (higher). Fan: 50–70% for functional parts, up to 80% for fine details.

Can I use PLA+ in an enclosure?

An enclosure isn't required for PLA+ (unlike ABS), but it doesn't hurt. If your enclosure gets above 45 °C ambient, watch for heat creep, especially with all-metal hotends. PLA+ handles cool open-air printing perfectly.

Does PLA+ need a hardened nozzle?

No. Standard brass nozzles work fine for all non-filled PLA+ variants. Only CF (carbon fiber) or metal-filled PLA+ composites require hardened steel nozzles.

What's the shelf life of PLA+?

Same as PLA — 1–2 years in sealed storage. PLA+ absorbs moisture like PLA and gets brittle/stringy when wet. Store vacuum-sealed with silica gel. If it snaps when you bend it or prints with lots of popping, dry it at 45–50 °C for 4–6 hours.

Is PLA+ food safe?

Technically the material can be food-safe (check the specific brand's SDS/TDS). However, FDM layer lines trap bacteria, and brass nozzles may contain lead. For food contact, use food-grade PLA with a food-safe nozzle — or better, use food-safe PETG.

Our Verdict

eSUN ePLA+ is the default choice — best value, proven consistency, massive color range. For parts that take real abuse, step up to Polymaker PolyMax PLA — the toughest PLA variant you can buy.

PLA+ is the sweet spot for 90% of functional FDM printing. Easy to print, significantly tougher than standard PLA, no enclosure needed, no exotic slicer settings. Just bump the nozzle to 220 °C, drop the fan a bit, and print.
