[中望动态] MiniMetalMaker：创客打造的金属3D打印机

早些时候，创客父子兵Scott Vader和Zachary Vader在纽约Maker Faire上展示了自己做的金属3D打印机。遗憾的是由于运输的过程中弄丢了喷头，所以只能让观众看看机器本身和以前打印出来的成品。( G+ W6 q" `* h2 F4 \2 p8 N! _- \0 ?

) x+ `6 s# a# j5 ?4 P而在indiegogo平台上，我们发现了另一台创客打造的金属3D打印机MiniMetalMaker。这台机器使用一种特殊的“金属粘土”，它由特定金属粉末和水溶性有机粘结剂混合而成。在制作金属模型的过程中，机器采用“滴蜡”的方式把融化后的“金属粘土”打印到平面上，成型后再放到一个温度介于600˚C-900˚C之间的陶器窑进行烧制，除去“金属粘土”里面的有机粘结剂。
6 K$ ^0 |1 x: j$ v; i2 l! }
! ]( E6 e) [8 q目前他们的机器可以打印含有金、银、铜、铁等几种材质的“金属粘土”，打印成型后可以根据实际需要对成品进行弯曲、抛光、钻孔等二次加工。目前机器最大的打印体积为6cm×6cm×6cm。% b4 O7 Q- M! t( C3 H$ u

3 Q$ e3 w, K! r" J! ^2 bMiniMetalMaker采用直驱涡轮控制着XYZ轴的运动，运动精度为每毫米1600步，运行速度达到10-100毫米/秒。目前这台机器的打印精度为450微米，未来他们要对机器进一步改进，让精度提高到200微米。8 C5 P* x( D4 a& F, t

. ]& V- K, q% ]/ j  x. j团队预计还需要六个月才能把机器完善，除了改进机器的设计构造、配套软件外，他们也想把MiniMetalMaker改造成双喷头，尝试不同材料之间的混合打印。- T/ W9 U( X, x4 F0 K# G
; S" V8 A7 {$ I* Z+ C6 K6 {( o
他们希望产品使用起来能够像Makerbot那样简便，并进而把自己演变成不同“金属粘土”的材料生产供应商。2 l' Z  e; c/ ~7 Z4 k/ M( a+ h, b
4 u5 w8 v( {3 M6 z+ R
最后想问问大家的是，家用的金属3D打印机未来是否会受到政府更多的管制？早些时候媒体曝光了全球首款D打印金属的手Qiang，能够发射50枚ZiDan。如果不设置相关法律限制不法分子获得这种设备的途径，恐怕未来谁都能轻易买到各种金属武器了。& h1 E' w! y4 w4 {8 }) o

前面介绍过让孩子感知手上产生“气”的游戏，这个游戏同样可以用于感知大脑。在这个过程中孩子的眼神和表情会变得非常平静祥和，因为纷繁复杂的感情会在能量中得到满足和释放。同样，通过集中注意力锻炼呼吸的游戏也可以感觉到自己和大脑合而为一。1 Y! H* e" T5 \) M% A2 U6 W* {
