SUNLU PLA+ 2.0 3D Printer Filament: problems, parts and running costs

Checked: 2026-10-19

Summary

The complaints that keep coming back are moisture — 3D Printer World says SUNLU complaints “are usually about wet spools rather than bad plastic” — and dial-in difficulty on some printers, while other owners print it with the stock Bambu Studio profile and no tweaking. There are no parts, repairs or subscriptions; the only running cost is the filament itself, listed at $10.99/kg at the SUNLU store in October 2026. It is a good buy at the SUNLU direct price, and worth walking away from above $19/kg.

Common problems and fixes

Temperature guidance conflicts — the store page gives one range, 205-220 °C, while the manufacturer page lists 205-215 °C at 50-100 mm/s and 215-245 °C at 100-200 mm/s; 3D Printer World advises trusting the label on 2.0 spools over older settings found online. [1][2][5]
Returns only on unopened spools — the refund policy allows 14 days for refunds and 30 for exchanges, but for FDM filament only unopened products are accepted. [3]
Some owners see no difference — an r/BambuLab owner noticed no difference versus other PLA, and an r/3Dprinting thread asks whether the 2.0 earns its name. [9][10]

Parts and consumables

PLA+ 2.0 filament, 1.75 mm — the only consumable; $10.99/kg at the SUNLU store, compare-at $18.99 (October 2026); $12.59/kg at the SUNLU store and $13.99/kg at other retailers per 3D Printer World’s August 2026 check; about $19/kg per All3DP’s 2024 buyer’s guide. Spool sizes run 0.25-5 kg. [2][5][6]
No replacement parts — none exist; SUNLU’s warranty statement explicitly excludes FDM printing consumables, so a bad spool is handled through the return policy rather than a warranty claim. [4]

Yearly running cost

The only recurring cost is the filament itself. At $10.99/kg (SUNLU store, October 2026) a year of printing costs the price per kilogram times the kilograms printed; the research contains no per-year consumption figures, so no yearly total can be computed. There are no subscriptions, replacement parts or repairs.

When it is a good buy

SUNLU’s own store lists it at $10.99/kg (compare-at $18.99) in October 2026; 3D Printer World’s August 2026 check had it at $12.59/kg at the SUNLU store and $13.99/kg at other retailers; All3DP’s 2024 buyer’s guide had the PLA+ category at about $19/kg. [2][5][6]

At the SUNLU direct price it is a budget pick for an easy-to-print, low-clogging toughened PLA.
At $12-14/kg from third-party retailers it remains a budget option.
Above $19/kg the research points to alternatives with longer track records.

Alternatives: ELEGOO PLA+ is the better choice when dial-in difficulty matters — the January 2025 owner found it less finicky; eSUN PLA+ and Polymaker are the better choice above $19/kg; Overture PLA+ competes in the same budget segment. [8]
