早在2014年美國(guó)海軍就提出了“打印艦艇”的概念 ,將增材制造及3D打印技術(shù)應(yīng)用到零部件的供應(yīng)鏈中,美國(guó)海軍人士稱,掌握增材制造技術(shù)將是海軍的優(yōu)勢(shì)之一,如果能在船的航行狀態(tài)下使用3D打印技術(shù),將是一件里程碑式的事件,必將大量減少備品備件的攜帶量,增加武器、燃料及補(bǔ)給的攜帶量,從而顯著提高海軍的遠(yuǎn)洋力。
(2)3D打印船模。美國(guó)卡德洛克海軍水面中心采用3D打印技術(shù)成功打印出美軍醫(yī)療船模型,用于測(cè)試船上風(fēng)力氣流的情況,該中心科學(xué)家稱3D打印可以提供更快、更精準(zhǔn)及更低成本的艦船模型。如果將該技術(shù)推廣應(yīng)用,在相同和相似領(lǐng)域必將產(chǎn)生深遠(yuǎn)的影響。
(3)3D打印螺旋槳。2016年初,國(guó)外兩位發(fā)燒友嘗試采用3D打印技術(shù)制造螺旋槳,他們同時(shí)選用了4種材料進(jìn)行對(duì)比,取得了豐富的試驗(yàn)數(shù)據(jù)。
(4) 3D打印無(wú)人機(jī)。英國(guó)早在五年前就應(yīng)用3D打印技術(shù)打印了世界上第一臺(tái)無(wú)人機(jī)SULSA,經(jīng)過(guò)多次改進(jìn)后,于2015年進(jìn)行海上試飛試驗(yàn),盡管它只能飛行40min,但其低廉的成本和完成任務(wù)的表現(xiàn),足以使人們產(chǎn)生濃厚的興趣和繼續(xù)研究的決心。
2016年SULSA正式服役,為英國(guó)皇家海軍破冰船的南極之旅偵查路線。
美國(guó)海軍研究學(xué)院?jiǎn)?dòng)3D打印無(wú)人機(jī)項(xiàng)目,該項(xiàng)目將現(xiàn)代通信技術(shù)和裝備技術(shù)完美結(jié)合,為海軍執(zhí)行不同任務(wù)時(shí)打印出相應(yīng)的無(wú)人機(jī),2015年12月打印出一架反恐無(wú)人機(jī),可搭載反恐所需的通信設(shè)備。與英國(guó)不同的是,美國(guó)的3D打印無(wú)人機(jī)是在船上完成的,將3D打印技術(shù)又向前推進(jìn)了一大步。
(5)其他方面。增材制造除以上應(yīng)用外,還在發(fā)動(dòng)機(jī)鑄造模具、渦輪增壓部件及小艇模型等得到應(yīng)用,增材制造(3D打印)技術(shù)正在船舶領(lǐng)域的各個(gè)方面大顯身手。2016年1月7日,勞氏船級(jí)社頒布3D打印全球認(rèn)證標(biāo)準(zhǔn),旨在指導(dǎo)規(guī)范增材制造技術(shù)的推廣應(yīng)用。
3. 增材制造技術(shù)在船舶領(lǐng)域廣泛應(yīng)用的技術(shù)瓶頸
目前,增材制造3D打印技術(shù)在船舶行業(yè)的應(yīng)用相對(duì)于整個(gè)造船領(lǐng)域來(lái)說(shuō)只是冰山一角,遠(yuǎn)未達(dá)到廣泛應(yīng)用的程度,究其原因增材制造技術(shù)還是一門新興的科學(xué)技術(shù),還有很多技術(shù)瓶頸未能突破,比如以下幾個(gè)方面:
(1)增材制造材料的相對(duì)匱乏。傳統(tǒng)造船業(yè)所使用的材料主要為金屬材料,金屬材料的發(fā)展已有幾千年的歷史了,在這漫長(zhǎng)的歷史長(zhǎng)河中金屬材料的種類多種多樣,性能各異,制造工藝也日益成熟,可以滿足船舶制造的不同需求。而增材制造所使用的材料相比之下少之又少,制造的產(chǎn)品也遠(yuǎn)不能滿足使用要求。因此,原材料的種類性能不能有大的進(jìn)展,將直接影響增材制造技術(shù)的推廣使用。
