SainSmart LW-PLA Filament Overview

SainSmart LW-PLA (Lightweight PLA) is a 3D printing material specially developed for aeromodelling drones and cosplay. Compared with regular PLA Filament, printing with the LW-PLA Filament delivers a lighter wing load and a lower stall speed to your aircraft models. With a better balance between strength and weight, it also brings better performance to your models.

The expanding property of this PLA Filament allows for excellent layer bonding, better drop resistance, and repairability. In combination with the low-density feature, this filament is a perfect option for RC planes, drone parts, and cosplay models.

Features

Light Weight

With active foaming technology, this LW-PLA filament delivers low-density and lightweight parts. The SainSmart LW PLA Filament has a density of 0.54 g/cm³, resulting in a significant weight reduction for your printed parts, perfect for RC planes and drones. The reduced weight enables lower wing loads and stall speed, allowing for overall better performance.

Active Foaming

The foaming expansion of this LW PLA filament allows you to print with up to 2X material flow. The maximum foaming rate of this LW-PLA filament is 220%, meaning that one roll of LW-PLA can be used as 2.2 rolls of ordinary PLA. This allows you to print more with less material.

Smooth Finish

Models printed with this LW PLA filament have a smooth matte surface with minimal layer lines. The improved paint adhesion also enhances your creativity. The foaming feature allows for almost invisible layer lines and a smooth matte finish.

Customizable Expansion Effects

The LW PLA filament will start expanding at certain printing temperatures above 210℃. By adjusting the printing temperature, speed, and flow during your print, you can customize the expansion effect for different densities in various sections of a model.

LW-PLA has stable interlayer bonding, and the expansion rate, density, and strength can be controlled by adjusting the printing temperature.

Love it
Color: Dark Green, Size: Small
I got the dark green. Love the sweater and it's warm. I do layer the sweater as well. It is as pictured. Size is perfect to me. I like sweaters to be longer and a bit wider in case it is freezing and I need to layer it. This sweater is perfect for layering. It comes closer to my backside, it is a little wide and not snug, and I like that the sleeves come over my wrists

Still soft but looks terrible after 1 wash. Save your money
Color: White, Size: Small, Color: White, Size: Small
Update: sweater looked great when I received. After 1 wash it looks terrible. Looks like it’s been washed too many times, material fuzzy and piled. After wearing it once, it snagged and the knit pulled through. I would NOT recommend. I had such high hopes. Save your money. Very nice sweater, especially for the price! I love the details of the buttons on the sleeves. It is SO soft. It’s not super thick as I can see my skin through it when pressing my hand up against fabric. However, it’s not see through when wearing it. It’ll be perfect in cooler weather and perfect in the winter with a coat but won’t cause me to overheat when in a heated environment. I do feel like it runs big. I could have sized down a size. Although I’m not sure if it’ll shrink after a wash or two.

Disappointed.
Color: Blue, Size: Large, Color: Blue, Size: Large
This sweater is so comfortable and very soft. It fits well in a flattering, oversized way. But after one wash it is pilled everywhere which makes it look old and shabby. It’s at a price point where I feel compelled to return it.

Perfect for casual wear and dressy style
Color: Dark Green, Size: Small
This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.

Love the long sleeves!!!
Color: White, Size: Small
Love it! I'm 5' 11" tall and I purchased this according to reviews. Several people commented on the length of the sleeves. I have a hard time finding sleeves long enough if it's not " tall" sized. It was perfect for me. If this washes nice I'm going to consider purchasing more in other colors. I ordered the white and just love the long ribbed cuffs with the line of buttons. Very soft.
