PLA (Polylactic Acid) is the filament almost every 3D printer ships with a sample of, and for good reason — it’s the easiest material to print well, the most forgiving of beginner mistakes, and the cheapest to experiment with. If you’re trying to decide what to load first, the short answer is: PLA, and here’s exactly why.
What Is PLA, Actually?
PLA is made from renewable, plant-based sources — typically corn starch or sugarcane — rather than the petroleum base most other filaments use. That’s part of why it prints at a lower temperature and with less warping than materials like ABS: it behaves differently as it cools, shrinking less and curling less on the way down.
It’s biodegradable under industrial composting conditions (not in a regular household bin, despite what that sounds like), rigid rather than flexible, and the most dimensionally accurate common filament — meaning what you design is very close to what prints, without much tuning.
Why PLA Is Genuinely the Right Beginner Material
Low print temperature. PLA prints at 190-220°C, well below PETG or ABS. Lower temperatures mean less that can go wrong with a printer whose settings you’re still learning.
No heated bed required. PLA sticks to a cold bed reasonably well on its own. A heated bed (50-60°C) helps, especially on larger prints, but you’re not troubleshooting bed adhesion and material behaviour at the same time.
Minimal warping. PLA shrinks very little as it cools, so it doesn’t lift off the bed or curl at the corners the way ABS does on an open-frame printer.
No enclosure needed. Print it on an open-frame printer in a normal room without issue.
Barely any smell. Unlike ABS’s noticeable fumes, PLA has almost none, which matters if your printer is somewhere you spend time.
PLA Print Settings That Work
| Setting | Range | Notes |
|---|---|---|
| Nozzle temperature | 190-220°C | Start around 200°C and adjust based on layer adhesion and stringing |
| Bed temperature | 0-60°C | Not required, but helps first-layer adhesion |
| Print speed | 50-80mm/s | PLA cools fast, so it tolerates higher speeds than PETG or ABS |
| Cooling fan | 80-100% | Unlike PETG, PLA wants strong cooling for crisp detail |
| Retraction | 1-3mm | Generally needs far less than PETG to avoid stringing |
If you take one thing from this table: PLA wants more cooling fan than almost any other material, which is the opposite of what you’ll later learn for PETG. Getting this backwards is one of the most common beginner mix-ups when moving between materials.
PLA’s Real Limitations
PLA isn’t the right material forever, and it’s worth knowing why before you’re surprised by it:
- It softens in heat. A PLA part left in a car on a sunny South African afternoon will visibly deform. Anything that’ll see real heat needs PETG or ABS instead.
- It’s more brittle than PETG or ABS. PLA doesn’t flex much before it cracks, which makes it a poor choice for anything that needs to bend or absorb repeated impact.
- It degrades with UV and age. Outdoor PLA parts get brittle and discoloured over months, faster than PETG in the same conditions.
None of this makes PLA a “worse” material — it makes it the right tool for prototypes, display pieces, indoor functional parts, and learning, and the wrong tool for anything that needs to survive heat, sun, or repeated stress.
Standard PLA vs PLA+ vs Specialty PLA
Not all PLA is the same rigidity-vs-toughness trade-off:
- Standard PLA (R295/1kg — Creality Ender PLA, Soleyin Ultra PLA) is the baseline: easy, consistent, wide colour range.
- PLA+ (R325/1kg — Creality Ender PLA+) is reformulated to be noticeably less brittle, worth the small premium for anything that’ll be handled a lot rather than just displayed.
- Silk PLA (R395/1kg — ERYONE Silk PLA) trades a small amount of layer strength for a genuinely shiny, reflective finish — popular for decorative prints where looks matter more than mechanical performance.
- Hyper Speed / Matte Gradient PLA (R415/1kg — ERYONE Hyper Speed Matte Gradient Rainbow PLA) is tuned to print well at higher speeds while shifting colour through the print, without you adjusting settings between colours.
For your very first prints, standard PLA is the right choice — save the specialty lines for once you’re printing reliably and want to see what they can add.
Common PLA Myths, Cleared Up
“PLA is weak.” It’s more brittle than PETG, but its raw layer strength is comparable to ABS in the right print orientation. “Weak” isn’t quite accurate — “less forgiving of sudden impact” is.
“You need a heated bed for PLA.” Helpful, not required. Plenty of PLA prints come out clean on a cold bed with a bit of adhesion help (a brim, or a bed surface with more grip).
“All PLA prints the same.” Close, but not exact — different brands and colours can need a few degrees of temperature adjustment. Keep notes on what works for each spool rather than assuming one setting fits everything.
Getting Started
Pick any standard PLA colour, set your nozzle to 200°C as a starting point, your bed to 50-60°C if you have one, and your cooling fan to full once the first layer’s down. Adjust from there based on what you see — stringing means less temperature or more retraction, poor layer adhesion means more temperature or less cooling.
