    CNC machinery requires power too. I have no doubt CNCing makes sense for large-scale mass production, but for small companies like Bastion who plan on making only a couple hundred bikes a year with customized lug geometry, laser-sintering makes some amount of sense.

    Actually, the first carbon bike frame was a prototype developed by Carlton Bicycles in England in 1971. That bike never went into production, nor did the one developed for Graphite USA (a fishing rod manufacturer) in 1975. That year, Graftek - another manufacturer of fishing rods and golf clubs - developed the Graftek G-1, a frame made of carbon wrapped aluminum tubes. This was used by the 1976 US Olympic team and was sold to the general public the next year. I remember that Dixon's Bicycles in Athens, GA still had a 56cm one in 1980. the frames had a reputation for coming unglued so he was unable to sell that bike and allowed any of us to ride it because if we could make it come apart Graftek would refund his money.

    Vitus used this method (carbon wrapped aluminum tubes) for tubes for Peugeot, used in the 1982 TdF. It was 1986 that the first Look carbon frames were released and used in LeMond's historic victory in that race.
    Life is short... enjoy the ride.
