Is PLA waterproof after printing
PLA: PLA should work fine as a waterproof 3D print. However, you have to be careful that it doesn't get exposed to hot water or conditions as they can easily melt. One example of a waterproof item you can create with PLA is a soap dish.
Can PLA survive in water
Many people use PLA in aquariums, bathtubs, or pools without issues. Tests have been run with PLA underwater and it has lasted for years. It should be the same with salt water also. PLA doesn't dissolve or degrade in water like some may think.
How weatherproof is PLA
PLA isn't known as the most waterproof material, but it does the job. It should work fine as long as it's interacting with cold rather than hot water. ABS is an excellent material for waterproof printing.
Does PLA prints absorb water
Does PLA Absorb Water PLA does absorb water and can cause printing problems. Most of the time when you use PLA that has moisture, it will extrude from the nozzle causing bubbles that can damage your print and its smoothness.
What happens if PLA gets wet
You will not damage the model with water using that material. PLA is biodegradable, and a bit easier to work with. Neither ABS or PLA will degrade much in water.
How long does PLA last in water
47 to 90 days
However, PLA is not water-resistant, which means it absorbs water and decomposes over time. PLA in water can generally last 47 to 90 days, which is pretty much faster to decompose than PET material. PLA objects in water can even break down faster with high temperatures.

How quickly does PLA absorb water
Studies by other researchers have revealed that PLA is relatively stable in water at moderate temperatures (15 °C–040 °C) and can absorb between 0.7 and 1 wt% water when immersed for 30 days [48] and slightly more at much longer periods of immersion [49].
Does PLA melt in the sun
But what happened to the blue. Well it lasted less than two days outdoors. Before it faded to its base color and never returned this robot wheel was printed in the same material.
Does PLA break down in the ocean
PLA biodegrades according to ASTM standards under industrial compost conditions but not in marine water. 19 Thus, very little biodegradation products and chemical intermediates will be formed in marine water tests since the PLA is biodegrading very slowly.
How do I know if PLA is too wet
If the filament is wet, you will be able to see bubbles forming in the extruded material. Alongside this, one should be able to hear a hissing sound. If the filament has a lot of moisture, one might be able to see steam exit the nozzle. Hygroscopic filaments that have been exposed to a lot of moisture tend to swell up.
What happens when PLA gets moist
Because some 3D printing filaments are hygroscopic, meaning that they absorb moisture from the air, prolonged exposure to even moderately humid room air causes moisture saturation. After 150 hours in standard conditions, PLA filament may swell up to 40 micrometers before reaching its saturation point.

Why PLA is not sustainable
This is still plastic, but definitely more sustainable than new material. PLA consists of renewable raw materials and is biodegradable in industrial composting plants. However, due to the lack of infrastructure, it is difficult to compost PLA industrially or to recycle it.

Is PLA really eco friendly
Lower Carbon Footprint
The manufacturing process for PLA is also more environmentally friendly than traditional plastics. Ingeo PLA bioplastic produces 80% less greenhouse gas emissions compared to conventional plastic derived from fossil resources (source).
Does PLA degrade in the ocean
They should not be present during the biodegradation of PLA at lower temperatures found in composting or in the marine environment. PLA biodegrades according to ASTM standards under industrial compost conditions but not in marine water.
What is the disadvantage of PLA
Because PLA is made of organic materials, it has higher permeability than other plastics. Moisture and oxygen will possibly be able to penetrate through PLA. That leads to food spoilage, so it's not advised to use PLA for long-term storage of food products.

Why is PLA not widely used
The biggest problem with PLA is the very specific conditions needed in order for it to be properly composted. Instead of being recycled with regular plastic materials, PLA needs to be sorted separately and brought to a 'closed composting environment' as otherwise it contaminates the recycling stream.
Does PLA last long
In short, when you place PLA under normal room temperature, it can last for a very long time – say 12 to 18 years. Depending on where and how you store it, 3D printed objects made from PLA can last from a month, to 2 years and up to many years. It can break down at different rates depending on its environment.
Why does PLA degrade in water
So just about every material used in the 3D printing world (PLA, ABS, Nylon, PC, etc.) are hygroscopic to some extent, meaning that the plastics have a strong affinity to attract moisture and that they will absorb moisture into their internal molecular structure if left in a humid/wet environment.
How long will PLA last
While in an adverse environment, PLA is said to last between a few months to two years. While PLA is not water-soluble, it has a fairly high rate of water absorbency, or in technical terms, is hygroscopic. Exposure to moisture will lead to poor results when put into your 3D printer with the high-temp nozzle.
