PLA, or polylactic acid, is the most commonly used 3d printing materials. PLA is an environmentally friendly material that is easy to print and is more environmentally friendly than other plastics. eSUN's pla+ is FDA-approved and safer to use. So what are the characteristics of pla filaments?https://www.esun3d.com/

Advantages of PLA 3D printing materials
Finished products:
1. The printed surface is smooth

2. Easy post-processing

3. Biodegradable

4. Available in various colors or easily made into colors

5. Drying can increase the hardness

During manufacturing:
1. 3D printing is fast and easy

2. Lower printing temperature

3. Low shrinkage
Disadvantages of PLA 3D printing materials
Finished product:
1. Not durable

2. Soften (may bend or twist) at about 140°F (60°C)

3. Not resistant to UV light

During manufacturing:
1. Absorb moisture in the air

2. Sometimes the print head is blocked

PLA is one of commonly used 3d printing materials. Whether it is printing equipment or materials, the price is relatively cheap, but the size error of pla filament molded parts is slightly larger, and the surface quality is relatively rough. eSUN PLA+ is based on the modification of PLA material, which improves the toughness and interlayer bonding force. PLA+ has balanced strength, rigidity and toughness, strong impact resistance, and the lines are not easy to be brittle.https://www.esun3d.com/pla-pro-product/

If you like pla filaments but don't want to take risks, it is recommended to choose esun pla+, which has more powerful performance.https://www.esun3d.com/pla-filaments/
