Towards the *fully* 3D-printed electric cars.

Also, the other option that 3D printing opens up is more shape optimized parts. These things are optimized so that "useless" mass is simply gone from the design. They tend to look "organic" rather than "machined" due to their complex shapes. I've heard this called "light-weighting" parts from management types. Sometimes you light-weight a part too far. Back in 1985, my mechanic called me in to look at a repair. The new brake disk was much heavier and much less "organic". But the original one warped because it didn't have enough mass to absorb the heat till it could be radiated away, and the manufacturer provided a much simpler but heavier replacement part. The new part was so much different looking than the original one that he wanted my permission to proceed. (As a 400 pound guy who likes to drive econobox microcars, I always seem to have alignment and brake problems only on the front left. Hmmm?) -- We are geeks. Resistance is voltage over current. |
