eSUN PLA-LW Black Filament 1 kg with Plastic Roll

eSUN PLA-LW Black is a black lightweight foaming PLA filament for FDM/FFF 3D printing, developed for aeromodelling, RC aircraft, ship models, cosplay, lightweight housings, technical mockups and thin-wall structures. The material uses active foaming technology: as the nozzle temperature increases, it expands inside the nozzle, allowing lighter parts to be printed with lower density and reduced actual material consumption.

Important package detail: this version is specified with plastic roll, not cardboard roll. A plastic roll is convenient for stable feeding, storage, spool holders and dry box use.

✅ Main advantages

• Black color: a strict technical shade for housings, RC parts, cosplay components, mockups and functional models.
• Lightweight after foaming: printed part density can be as low as 0.54 g/cm³.
• Foaming volume ratio up to 220%: at the correct temperature, the material expands and helps reduce filament consumption.
• Adjustable density and strength: printing temperature can be used to tune weight, stiffness and foaming level.
• Matte surface: finished parts look clean and soft without strong plastic gloss.
• Good interlayer bonding: suitable for thin-wall parts and lightweight structures.
• Plastic roll: more practical for storage, stable feeding and dry box use than cardboard roll.

🔧 How to tune black PLA-LW

• For the first test, start from the lower or middle part of the temperature range.
• The higher the temperature, the stronger the foaming and the lighter the part.
• At higher temperatures, reduce flow rate because the material expands inside the nozzle.
• Black color is useful for technical models where a light paintable base is not required.
• Do not print many separate objects at once: travel moves between models increase stringing.
• For aircraft models and thin-wall parts, use vase mode when the model supports it.
• If excessive strings appear, lower temperature and reduce unnecessary travel moves.

🧩 Best applications

• ✈️ RC aircraft, wings, fuselages and lightweight aeromodelling parts.
• ⛵ Ship models, boat hulls and display components.
• 🎭 Cosplay props, lightweight helmets, panels and large-volume parts.
• 📐 Architectural models, educational models and prototypes.
• 📦 Lightweight housings, covers, shells and thin-wall parts.
• 🧩 Technical models that need a strict black appearance and reduced weight.

✅ 3D printer compatibility

eSUN PLA-LW Black is compatible with FDM/FFF 3D printers using 1.75 mm filament, provided that the printer supports the required nozzle temperature range and allows accurate flow rate, speed, cooling and first-layer tuning. It can be used with Creality, Bambu Lab, Prusa, Anycubic, Elegoo, Sovol, QIDI, Flashforge and other popular FDM/FFF printers.

If printing above 250 ℃, hotend design is important. For long prints in the upper temperature range, an all-metal hotend is preferred, because many printers with PTFE/Teflon tubing are not intended for long-term printing at such temperatures.

🛠️ Printing recommendations

• Before printing a large model, run a temperature test on your exact printer.
• Do not use a standard PLA profile without tuning flow and temperature.
• Tune flow rate according to the selected foaming temperature.
• Make sure the first layer is not excessively over-extruded.
• If bed adhesion is too strong, use a raft, separation layer or adjusted base settings.
• To reduce stringing, lower temperature and avoid printing several separate objects at the same time.
• For aircraft models, use models prepared for LW-PLA or vase mode.

📦 Storage and drying

• Store the spool in a dry place, preferably in a sealed bag or dry box with desiccant.
• Do not leave the filament exposed in a humid room.
• The plastic roll is convenient for repeated storage and spool holder use.
• If bubbles, popping, unstable extrusion or excessive strings appear, dry the filament before printing.
• For long prints, using a dry box is recommended.

❓ FAQ

 

 

Is this black PLA-LW supplied with plastic or cardboard roll?

This product card specifies eSUN PLA-LW Black 1 kg with plastic roll, not cardboard roll.

Is PLA-LW Black the same as regular black PLA?

No. It is a PLA-based lightweight foaming material. It requires separate temperature, flow and speed tuning.

Why does PLA-LW string?

PLA-LW keeps foaming inside the hot nozzle zone, so retraction is almost ineffective and stringing is considered normal. To reduce the effect, lower temperature, avoid printing many separate objects at once and use vase mode for suitable models.

Can PLA-LW be printed on a regular 3D printer?

Yes, if the printer supports the required temperature range and allows flow-rate tuning. For long prints above 250 ℃, an all-metal hotend is recommended.

What is black PLA-LW best for?

Black PLA-LW is especially useful for technical models, RC parts, housings, cosplay components and prints that need a strict dark appearance with minimum weight.

 

 

🚀 Why buy

eSUN PLA-LW Black 1 kg is a good choice for lightweight models where weight, volume and temperature-controlled density matter. The black color is suitable for technical parts, housings and RC models, while the plastic roll makes the material practical for storage and stable feeding.
