第一支完全3D打印槍支問(wèn)世

第一支完全3D打印槍支問(wèn)世

Matt Vella 2013-05-08
美國(guó)德州的非盈利組織Defense Distributed日前公布了一組圖片,稱(chēng)它已經(jīng)生產(chǎn)出了世界上第一支完全采用3D打印技術(shù)制造的槍支。據(jù)報(bào)道,槍支設(shè)計(jì)者還打算最終在網(wǎng)絡(luò)上發(fā)布圖紙以及這支手槍的詳細(xì)操作方法,讓人們?cè)谧约杭依锞涂梢宰孕小按蛴 边@支手槍。

????3D打印機(jī)術(shù)有很多光明前景,其中包括打印復(fù)雜的原型產(chǎn)品、款式獨(dú)一無(wú)二的珠寶,甚至是打印人體組織。不過(guò)現(xiàn)在,有一個(gè)組織又發(fā)現(xiàn)了3D打印的另一用途,那就是制造槍支。

????德克薩斯州非盈利組織Defense Distributed是由一名年僅25歲的德州大學(xué)法律系學(xué)生科迪?威爾森創(chuàng)辦的。該組織近日給《福布斯》雜志的網(wǎng)站Forbes.com提供了一些圖片,聲稱(chēng)圖片中的槍支就是世界上第一支完全采用3D打印技術(shù)造出的手槍。這個(gè)組織還表示,這支手槍可發(fā)射標(biāo)準(zhǔn)的手槍子彈。這支手槍的名字叫“解放者”(Liberator),它的主體部分完全是用塑料制造的,只有撞針是金屬。另外,槍里還裝了一塊6盎司的鐵片,目的是為了讓這支槍能夠被金屬探測(cè)器探測(cè)出來(lái)。

????去年,威爾森宣布打算利用3D打印技術(shù)制造一支槍的時(shí)候,他的大膽計(jì)劃就吸引了大量關(guān)注。這個(gè)組織大概花了8個(gè)月的時(shí)間設(shè)計(jì)出了“解放者”。

????3D打印技術(shù)也叫疊加制造技術(shù),它是一種可以通過(guò)電腦模型制作出三維實(shí)物的技術(shù)。簡(jiǎn)單來(lái)說(shuō),3D打印機(jī)通過(guò)連續(xù)不斷地疊加塑料材料,幾乎可以塑造出任何形狀的物體。3D打印機(jī)也可以制造出具有連鎖機(jī)制的零部件,比如齒輪和接榫等。這個(gè)過(guò)程與傳統(tǒng)加工方法存在顯著的區(qū)別,后者通常是通過(guò)對(duì)大塊材料進(jìn)行切割或雕塑來(lái)加工復(fù)雜的零件。

????據(jù)波士頓Luxe Research研究公司預(yù)測(cè),到2025年,3D打印市場(chǎng)的市值將從現(xiàn)在的7.77億美元猛增到84億美元。其中大多數(shù)增長(zhǎng)是由商業(yè)應(yīng)用驅(qū)動(dòng)的,尤其是在醫(yī)藥、汽車(chē)和航空領(lǐng)域。

????The many promises of 3D-printing include intricate product prototypes, one-of-a-kind jewelry, even human tissue. Now, a group has revealed a proof-of-concept of another sort: a gun.

????Texas-based Defense Distributed, founded by 25-year-old University of Texas law student Cody Wilson, has given Forbes.com images it says show the first 3D-printed handgun. The group, which is aiming for nonprofit status, claims the weapon can fire standard handgun rounds. The majority of the device, called the "Liberator," is fabricated entirely out of plastic, save for a nail used as a firing pin as well as a six-ounce piece of steel, intended to allow the gun to be detected by metal detectors.

????Wilson generated headlines last year when he announced his plans to produce a 3D-printed gun. It took the group about eight months to design the Liberator.

????Also known as additive manufacturing, 3D printing is a method of making a three-dimensional solid objects from a computerized model. Commonly, 3D printers lay down successive layers of plastic material to create objects of virtually any shape. The printers can also create interlocking mechanical parts, such as gears and cogs. The process is distinct from traditional machining, in which objects are whittled or sculpted down from larger blocks of material.

????Boston-based Luxe Research estimates that the $777 million 3D printing market will grow to a whopping $8.4 billion by 2025. Most of that growth will be driven by industrial applications, particularly in medical, automotive and aerospace industries.
