/diy/ - Do It Yourself

>>652462
The most practical things I have seen 3d printed are widgets for airplanes. Little plastic parts that do things like channel air for air conditioning and hold wires in place.

It's cheaper to print them than to make them with injection molding. Plus with additive manufacturing they can be made lighter than if they were to be made by injection molding.

Because airplanes tend to have a lot of these 'widgets' in them, doing so saves millions of dollars worth of fuel over the aircraft's lifetime
