The study found that PLA is Generally Recognized As Safe (GRAS) when used in contact with food. Their summary concluded that PLA releases a small amount of lactic acid into foods. Lactic acid is a common food ingredient, that is even found in breast milk. Most PLA is coloured.
What color is a PLA?

Can you 3D print clear?
Yes! Multi-material 3D printing technology makes creating custom translucent and transparent parts easier than ever. Read on to find out more about transparent materials, how 3D printing them works, and possible applications.
Is PLA naturally clear?
In its purest form, PLA is made of natural materials like cornstarch. Because of this, PLA is inherently somewhat transparent. Pure PLA, however, isn't as transparent as you might expect or want it to be; it can often look a bit yellow when printed.Jan 9, 2021
What colors does PLA come in?
The color change PLA filaments come in three varieties: green to yellow, gray to white, and purple to pink.
What is natural PLA filament?
PLA (polylactic acid) is a biodegradable plastic that is obtained from natural resources, specifically it's obtained from the starch extracted from corn, beets and wheat. PLA is one of the most used materials in 3D printing today because it doesn't give off harmful gases and its ease of printing.
Is PLA better than plastic?
Producing PLA uses 65 percent less energy than producing conventional plastics, according to an independent analysis commissioned by NatureWorks. It also generates 68 percent fewer greenhouse gases, and contains no toxins.
What is PLA good for?
Polylactic Acid, commonly known as PLA, is one of the most popular materials used in desktop 3D printing. PLA is a great first material to use as you are learning about 3D printing because it is easy to print, very inexpensive, and creates parts that can be used for a wide variety of applications.
Is PLA plastic strong?
PLA is stronger and stiffer than ABS, but poor heat-resistance properties means PLA is mostly a hobbyist material. ABS is weaker and less rigid, but also tougher and lighter, making it a better plastic for prototyping applications.
