An ABS 3D Print in the Sun

The screws are rusted, the brass inserts darkend with exposure to salt and rain, the post it is clamped to is likewise suffering from corrosion in the salt air, but the 3D print is just fine.

Some plastics used for 3D printing decay fairly rapidly with exposure to sunlight and weather. Certianly PLA, the most common 3D plastic, crumbles to dust in just a year of harsh weathering. ABS or Acrylonitrile Butadiene Styrene on the other hand, seems to perform quite well.

Working at Symbrosia I have created dozens upon dozens of designs, many of which are installed in the extremely harsh environment of our outdoor cultivation area. Here the prints sit in intense tropical Hawaiian sunlight for days on end, subject to both intense UV light and high temperatures. The plastic is also subject to continual exposure to salt water used in our operation, or raining from the sky on days with heavy surf, when the waves are crashing just 100 yards away. It does not get much worse than this.

Sea Chair

A wonderful little film and a neat idea. I will not spoil the effect by explaining here. Watch the film!

The film truly highlights the problem of plastic pollution in the ocean. Modern plastics do not decompose readily, but persist in the environment for decades. This is a problem that deserves more attention and should be in the mind of anyone who treasures our seas.

Apparently the biggest problem is not the large pieces of plastic like those used in making the chair, but rather the microplastics. Under the influence of wave and sunlight, plastic slowly breaks down into smaller and smaller bits. These are sand size or smaller granules that have come to pervade the entire ocean. The granules are easily ingested by the smaller creatures of the plankton community, the food on which all ocean life depends.

Walking a Hawaiian beach you see some plastic, even far from the major urban sources of this pollution. Walking the tide-line on any beach or cove reveals small bits of colorful plastic. There is not a lot, but it is always there.
