What the listings tell you, and what they leave out
Diameter accuracy is the best documented figure here: every listing states 1.75mm, with +/- 0.02mm on the SUNLU and ELEGOO picks and +/- 0.03mm on the Bambu Lab spool. Print speed is thinner ground: only the SUNLU listings state a range, at 50-100mm/s for the red spool and 100-300mm/s for the PLA+ 2.0 bundle, while the ELEGOO and Bambu Lab listings state no speed figure at all.
Pack size needs care. The bundles are not large single spools: the SUNLU PLA+ 2.0 bundle and both ELEGOO bundles hold 4 spools of 1kg each. Spool size is stated for the SUNLU picks only, at 8.00 in diameter, 2.50 in width and 2.20 in hub hole for the red spool, and at 195mm diameter, 57mm width and 63mm hub hole for the PLA+ 2.0 bundle. Warranty is the thinnest field of all: only the SUNLU PLA+ 2.0 bundle states a term, at 1 year.
Buying guide: choosing the best pla filament 1 kg
Match spool size to the printer
A 1kg spool suits printers with a standard spool holder, while a 4-spool bundle suits printers that run through filament steadily. Check the spool against the holder: the SUNLU red spool states 8.00 in diameter, 2.50 in width and 2.20 in hub hole, while the ELEGOO listings state no spool size. The FDM 3D printer hub covers the printers these spools fit.
Check tolerance and speed
Tolerance decides how steadily the filament feeds: +/- 0.02mm is stated on the SUNLU and ELEGOO picks, against +/- 0.03mm on the Bambu Lab spool. Speed decides how fast a print can run: the SUNLU PLA+ 2.0 bundle states 100-300mm/s and the SUNLU red spool states 50-100mm/s, while the other listings state no speed figure, so do not assume a speed for them.
Mind the bundle
A bundle marked 4kg holds 4 spools of 1kg each, which suits multi-color printing or stocking up in a single color. The SUNLU PLA+ 2.0 bundle holds black, white, red and Klein blue, and the ELEGOO bundle holds brown, beige, wood color and black, while the ELEGOO black bundle holds black only. Both ELEGOO bundles and the SUNLU PLA+ 2.0 bundle state vacuum sealing, which protects the filament against moisture before it is opened.
Project Match
- High-precision models and functional prints: SUNLU PLA+ 2.0 bundle, stated for high-precision models with a tougher blend.
- Multi-color printing: ELEGOO bundle in brown, beige, wood color and black, or SUNLU PLA+ 2.0 bundle in black, white, red and Klein blue.
- AMS printing: Bambu Lab PLA Black, stated AMS-compatible with RFID identification.
- Everyday printing in a single color: SUNLU PLA Red or Bambu Lab PLA Black, each a 1kg spool.
- Bulk printing in black: ELEGOO PLA Black bundle, with 4 spools of 1kg each.
How the scores add up
The HQ Score weighs performance, build, value, safety and warranty. For filament, safety means stated safety features, and none of these listings states one, so every pick scores 0 there. Only the SUNLU PLA+ 2.0 bundle states a warranty term. How we pick explains the weights.
| Product | HQ Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| SUNLU PLA+ 2.0 Bundle | 9.7 | 32 | 21 | 22 | n/a | 3 |
| ELEGOO PLA Bundle | 9.6 | 29 | 21 | 21 | n/a | 0 |
| Bambu Lab PLA Black | 9.5 | 29 | 20 | 19 | n/a | 0 |
| SUNLU PLA Red | 9.5 | 28 | 21 | 19 | n/a | 0 |
| ELEGOO PLA Black | 9.5 | 28 | 20 | 20 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
