SUNLU
Value-Focused PLA and PETG Lineups
About SUNLU
SUNLU is frequently mentioned in online 3D printing communities such as r/3Dprinting. The brand built its presence on PLA and PETG spools sold at prices below the premium tier.
The catalog covers PLA, PETG, ABS, and TPU, all vacuum-sealed with desiccant. Beyond filament itself, SUNLU has carved out a second identity with its S1 and S2 filament dryers - affordable heated boxes that rescue moisture-damaged spools and keep hygroscopic materials printing cleanly. That practical, problem-solving streak runs through the whole product line and explains much of the community goodwill.
SUNLU targets hobbyists first, and it shows: the buying experience on Amazon and AliExpress is frictionless, multi-packs bring the per-kilogram cost down further, and wholesale options exist for heavier users. If you print daily and judge filament by successful prints per dollar, SUNLU is the benchmark the rest of the value segment is measured against.
Key Filament Specifications
| Material | Nozzle Temp | Bed Temp | Tensile (MPa) | HDT (°C) | Key Notes |
|---|---|---|---|---|---|
| PLA | 200–240 °C | 50–60 °C | 40 ± 6 | 55 ± 5 | Beginner-friendly, low odor, no enclosure needed. Best for models, decor, prototypes. Low heat resistance. |
| PLA+ | 205–245 °C | 50–60 °C | 46 ± 5 | 56 ± 3 | Upgraded toughness vs. standard PLA; better impact resistance and layer adhesion. PLA+ 2.0 variant shares identical specs. |
| PETG | 240–260 °C | 60–70 °C | 48 ± 10 | 70 ± 5 | Balanced strength and chemical resistance; low odor. Slight stringing tendency — dry before use. High-Speed Matte variant runs 70–80 °C bed. |
| ABS | 250–290 °C | 80–100 °C | 35 ± 5 | 95 ± 5 | High strength and heat resistance for functional parts. Enclosure required to prevent warping; ventilate fumes. Easy ABS variant: 225–255 °C / 60–70 °C. |
| TPU 95A | 190–230 °C | 50–60 °C | 31 ± 3 | 47 ± 5 | Shore 95A flexibility for gaskets, phone cases, grips, wearables. Slow print speed recommended (20–40 mm/s); hygroscopic — dry thoroughly. TPU 90A variant: 220–240 °C / 30–60 °C. |
