eSun 1.75mm ePLA-LW Light-Weight Black Filament - 1kg Spool

ePLA-LW expands upon extrusion, with a density that can vary with extrusion speed and temperature so tweaking and testing is required. What would make you want to go back to the days of testing and tuning a filament to your printer? The fact that this stuff foams up as you print it; it's ideal for 3D printing structures where weight is at a premium, like model aircraft!

Not into models? Ok - how about cosplay? To make a nice, rigid helmet you'd have to spend a LOT of time printing and sanding to get something strong enough to hold up to cosplay wear-and-tear. Print it with the LW filament, which gives a foam-like rigidity and finishing ability.

eSun is a top supplier of 3D printer filament, and we're happy to be carrying their inventory. They are not some fly-by-night operation; eSun is an active part of the 3D printer community, and you'll often see them represented at Maker Faires and 3D Printer Expos. We've even been to their labs at the Shenzhen University grounds where they develop and test their product. They take excellent care with their production methods, and each spool comes vacuum sealed in a pouch with moisture-absorbing desiccant.

In short, eSun knows their stuff. We're extremely happy with the quality and consistency of their material.

Features:

• Up to 220% increase of volume. It's like getting 2.2 rolls for filament printing out of 1 roll!
• Similarly, make your prints up to only 45% the mass of normal PLA
• Excellent matte surface-finish
• Excellent layer adhesion

Specifications:

• 210-270°C nozzle print range (45-60℃ Bed)
• 0.54 grams per cubic centimeter (g/cm³)
• Melt Flow Index of 8.1(190℃/2.16kg) (what does this mean? Good stuff. Yeah, that's it.)
• Unmelted density: 1.2g/cm³
• IZOD Impact Strength: 8.58kJ/m2
• Tensile Strength: 32.2MPA
• Elongation at break: 68.9%
• Flexure Strength: 41.3MPa
• Flexure Modulus: 1701MPa
• Base chemistry: polylactic acid biodegradable thermoplastic
• 1.75mm nominal diameter (spec'd +/- 0.05, but is in practice closer to +/- 0.03)
• 1kg spools on transparent LARGE diameter (easy unspooling) reels, vacuum sealed with desiccant
• Printing notes:
  • START your print at 100% print speed. No slow-first-layer setting!
  • 40-80mm/s nozzle print speed
  • Due to foaming at the nozzle, retraction is practically impossible. Expect stringing!
