[music playing] i'm doctor north. [gunshots] i'm flying in totucson, arizona, to give the keynote to additivemanufacturing users group. these are the best ofthe best of 3d printing, so you better believe ihave my camera with me but with my travel schedulethese skies aren't always friendly.
i'm sitting here withcold chicken noodle soup, all these business cards isall the people i just met. this guy-- check this out. that's his card. made a 3d printed gun, andshot a hole in his card. i'm gonna go shootthe gun tomorrow. i enjoy guns. i enjoy all the stuffthat goes into making them work, becauseit's a little machine.
it takes a spark. it takes fuel. it takes a little bit of air. the miniature explosions thathappen, much like an engine-- being an engine, man, there'sthousands of little explosions that go on. that's cool stuff. he just started doing it in thecompany without anyone knowing. now it's turned into a big hitand everyone loves him for it.
what could go wrong? you're just printing a gun. and it wasn't to producea better or cheaper 1911. its sole purpose wasto prove the process for someone else'sdesign, not ours. i mean, that's johnbrowning's design. that design's 100 years old. take his design and bringit into manufacturing today. i think john browning wouldhave prototyped this way.
all right, we'regonna test this thing? yeah, let's go the range. you were in the service? yes. ok. what were you in? i was in the navy--did four years. i went to school tofix diesel engines. they're really bigon cross-training,
so the othertrainings that i went for were the master at armstraining, which got me pretty heavily into the firearms bit. fix an engine, put out a fire,and then go shoot the bad guy. [gun shots] now this gun was not madewith your everyday 3d printer. this was made with ahalf-million dollar direct metal lasersintering system. with dmls, objectsare made layer
by layer using a laser tosinter a metal powder together. sintering is a process wheremany small particles are turned into one largeparticle, or a solid. in this case a laser is used toheat up the particles, giving the atoms enough mobilityso that they can rearrange, and then form one largeparticle, or a solid. it's pretty cool. it feels like suchan accomplishment to hit 100 roundintervals with this thing.
i'll let doctor northput the round 4,500 through the 3d printed 1911. all right. no pressure, man. no pressure. [gun shot] right through the "o." that's impressive. it's exciting to me.
i get wrapped up in when youcan start to combine technology, and really advancedways of doing things, with these old things havebeen around for a long time. plus, that's a 45caliber pistol. yeah, it's prettypotent on the hand. yeah. you got a littlemark, too, don't you? a little love mark. looks kind of like ahickey, but from a 45.
