style="text-indent:25px">3D打印用金屬粉體需要采用純度較高的金屬粉體原料。形狀要求。常見(jiàn)的顆粒的形狀有球形、近球形、片狀、針狀及其他不規(guī)則形狀等。不規(guī)則的顆粒具有更大的表面積，有利于增加燒結(jié)驅(qū)動(dòng)。但球形度高的粉體顆粒流動(dòng)性好，送粉鋪粉均勻，有利于提升產(chǎn)品的致密度及均勻度。因此，3D打印用粉體顆粒一般要求是球形或者近球形。粉體粒度及粒度分布。研究表明，粉體是通過(guò)直接吸收激光或電子束掃描時(shí)的能量而熔化燒結(jié)，粒子小則表面積大，直接吸收能量多，更易升溫，越有利于燒結(jié)。此外，粉體粒度小，粒子之間間隙小，松裝密度高，成形后零件致密度高，因此有利于提高產(chǎn)品的強(qiáng)度和表面質(zhì)量。但粉體粒度過(guò)小時(shí)，粉體易發(fā)生粘附團(tuán)聚，導(dǎo)致粉體流動(dòng)性下降，影響粉料運(yùn)輸及鋪粉均勻。所以細(xì)粉、粗粉應(yīng)該以一定配比混合，選擇恰當(dāng)?shù)牧６扰c粒度分布以達(dá)到預(yù)期的成形效果。粉體的工藝性能主要包括松裝密度、振實(shí)密度、流動(dòng)性和循環(huán)利用性能。虹口區(qū)定制3D打印哪個(gè)品牌好3D打印金屬材料主要有粉末形式和絲材形式。</p><div

style="text-indent:25px">·3D打印，指的是采用材料逐漸累加的方法制造實(shí)體零件的技術(shù)，而傳統(tǒng)的制造方式，大多是減材制造。3D打印的過(guò)程，通常被稱作增材制造。在各領(lǐng)域，3D打印都被引入，從醫(yī)療保健到汽車動(dòng)力，3D打印能夠幫助我們完成一些以前不能完成的事，并且能夠幫助我們加速商品上市。3D打印常常被運(yùn)用到的，還是部件的生產(chǎn)。舉一個(gè)例子，在工業(yè)領(lǐng)域，常常需要3D打印去制作一個(gè)汽車發(fā)動(dòng)機(jī)的小零件，而這個(gè)小零件有著極其復(fù)雜的內(nèi)部結(jié)構(gòu)，用傳統(tǒng)的CNC制造方式是不可能完成的。 3D打印允許設(shè)計(jì)者快速?gòu)?fù)制原型，極大地節(jié)省了設(shè)計(jì)的時(shí)間，使得剛剛改進(jìn)的產(chǎn)品能夠更快地進(jìn)入市場(chǎng)。 3D打印機(jī)更加便攜，這使得制造突破了具體空間及時(shí)間的限制。人類可以隨時(shí)隨地制造出所需要的東西。未來(lái)人們可以把3D打印機(jī)帶到太空打印飛船零件。 3D打印的制造方式是增材制造而不是減材，所以它在一定程度上更加節(jié)省了材料，沒(méi)有浪費(fèi)。雖然材料是可循環(huán)使用的，但是這些可循環(huán)材料也是需要資金的，而3D打印可以較大節(jié)省這一部分成本。</p><p style="text-indent:25px">其他金屬材料如銅合金、鎂合金、貴金屬等需求量不及以上介紹的幾種金屬材料，但也有其相應(yīng)的應(yīng)用前景。銅合金的導(dǎo)熱性能良好，可以制造模具的鑲塊或火箭發(fā)動(dòng)機(jī)燃燒室。NASA采用3D打印技術(shù)制造了由GRCop-84銅合金內(nèi)壁和鎳合金外壁構(gòu)成的燃燒室，內(nèi)壁采用SLM工藝制造，再以電子束熔絲沉積完成外壁的制造。該燃燒室經(jīng)過(guò)全功率點(diǎn)火測(cè)試后，仍然保持良好的形狀，證明了3D打印工藝在節(jié)約大量時(shí)間和工藝成本的基礎(chǔ)上，取得了與傳統(tǒng)工藝同樣的效果。鎂合金是目前實(shí)際應(yīng)用中較輕的金屬，且具有良好的生物相容性和可降解性，其楊氏模量與人體骨骼也較為接近，可作為輕量化材料或植入物材料。但目前鎂合金3D打印工藝尚不成熟，沒(méi)有進(jìn)行大范圍的推廣。貴金屬如金、銀、鉑等多應(yīng)用于珠寶首飾等奢侈品的定制，應(yīng)用范圍比較有限。3D打印模具縮短了整個(gè)產(chǎn)品開發(fā)周期并成為驅(qū)動(dòng)創(chuàng)新的源頭。</p><div
