Filament is one of the clearest wins for buying on AliExpress: the factories behind SUNLU, ESUN, JAYO, KINGROON and Geeetech sell there directly, many listings ship from local warehouses, and multi-roll bundles bring the price per kilo well below what most local shops charge. This list covers what an FDM printer actually goes through in a year: an everyday PLA, bulk packs, PETG for functional parts, matte and silk for looks, TPU for flexible parts, ASA for outdoor use, and the three accessories that stop filament problems before they start.

Typical ranges for most printers. Always start from the temperatures printed on your spool's label: brands and colours differ.
| Material | Nozzle | Bed | Best for |
|---|---|---|---|
| PLA / PLA+ | 190–220 °C | 50–60 °C | Almost everything indoors; the easiest to print. PLA+ is a little tougher. |
| Matte / Silk PLA | 200–225 °C | 50–60 °C | Models and decoration. Silk is shiny but its layers bond less strongly. |
| PETG | 230–250 °C | 70–85 °C | Functional parts, brackets, things that get warm or wet. |
| TPU 95A | 210–230 °C | 40–60 °C | Phone cases, gaskets, feet, anything that must bend. Print slowly. |
| ASA | 240–260 °C | 90–110 °C | Outdoor parts that sit in the sun. Needs an enclosure and ventilation. |
How to Choose Filament on AliExpress
- Check the diameter — almost every current printer uses 1.75 mm; some older Ultimaker-style machines use 2.85 mm. The two are not interchangeable.
- Read the bundle, not the headline — the price shown is usually one roll or the cheapest colour. Multi-roll listings let you pick colours and material per roll: check the variant before you pay.
- Look at where it ships from — many filament listings ship from warehouses in the US or Europe, which is much faster for something this heavy. The shipping option on the listing shows it.
- Keep it dry — PETG and TPU in particular absorb moisture from the air, which shows up as stringing, popping and weak parts. Store opened spools sealed with desiccant, and dry them before a long print.
- Mind abrasive filaments — glow-in-the-dark, carbon-fibre and metal-filled filaments wear out a brass nozzle quickly; switch to hardened steel and raise the temperature by 5–10 °C.
❓ FAQ
Is filament from AliExpress any good?
From the factory brands, yes: SUNLU, ESUN, JAYO, KINGROON, ERYONE and Geeetech are the same companies whose filament is sold in western shops, and they sell on AliExpress directly. Stick to listings with many orders and recent reviews, and avoid unbranded rolls with no stated tolerance.
What is the best filament to buy on AliExpress?
For most people, our first pick, the ESUN PLA+ 1 kg, the everyday spool (±0.03 mm, 20+ colours). It prints easily on any printer, comes in many colours and has a stated tolerance of ±0.03 mm. Buy a bundle once you know which colours you use most.
How much does filament cost on AliExpress?
The picks above range from $2.99 to $77.93, from a single nozzle to a 10 kg bundle. Per kilogram, the multi-roll packs are usually the cheapest. Prices change often, by colour and bundle size.
PLA or PETG: which should I buy?
Start with PLA: it is the easiest to print and fine for most indoor objects. Choose PETG for parts that need to be tougher or that sit somewhere warm, such as a car, near a heater or in sunlight, where PLA can soften.
Do I need a filament dryer?
Not for PLA in a dry room. A dryer is worth it if you print PETG, TPU or nylon, live somewhere humid, or see stringing and popping sounds. A dryer that feeds the printer while drying, like the eBOX Pro, also helps on long prints.
Will these spools work with an automatic material system?
Check the spool width and outer diameter against your system's limits. Some brands use cardboard spools, which can shed fibres in enclosed feeders; a printed adapter ring or a plastic spool version avoids that.
