style="text-indent:25px">3D打印即快速成型技術(shù)的一種，又稱增材制造，它是一種以數(shù)字模型文件為基礎(chǔ)，運(yùn)用粉末狀金屬或塑料等可粘合材料，通過逐層打印的方式來構(gòu)造物體的技術(shù)。3D打印通常是采用數(shù)字技術(shù)材料打印機(jī)來實現(xiàn)的。常在模具制造、工業(yè)設(shè)計等領(lǐng)域被用于制造模型，后逐漸用于一些產(chǎn)品的直接制造，已經(jīng)有使用這種技術(shù)打印而成的零部件。該技術(shù)在珠寶、鞋類、工業(yè)設(shè)計、建筑、工程和施工（AEC）、汽車，航空航天、牙科和醫(yī)療產(chǎn)業(yè)、教育、地理信息系統(tǒng)、土木工程、工具以及其他領(lǐng)域都有所應(yīng)用。</p><p style="text-indent:25px">3D打印用的光敏樹脂有以下幾點(diǎn)要求：固化前性能穩(wěn)定，一般要求可見光照射下不發(fā)生固化；反應(yīng)速度快，更高的反應(yīng)速率可以實現(xiàn)高效率成形；粘度適中，以匹配光固化成形裝備的再涂層要求；固化收縮小，以減少成形時的變形及內(nèi)應(yīng)力；固化后具有足夠的機(jī)械強(qiáng)度和化學(xué)穩(wěn)定性；毒性及刺激性小，以減少對環(huán)境及人體的傷害。在一些特殊的應(yīng)用場合還會有一些其他的需求，如應(yīng)用于鑄造的光敏樹脂要求低灰分甚至無灰分，再如應(yīng)用牙科矯形器或植入物制造的樹脂要求對人體無毒或可生物降解等性能。目前市面上銷售的光敏樹脂種類多樣，能夠滿足不同領(lǐng)域的需求。3D打印技術(shù)實際上是利用光固化和紙層疊等技術(shù)的較新快速成型裝置。</p><div

氧化物陶瓷物理化學(xué)性能穩(wěn)定，燒結(jié)工藝比較簡單，是陶瓷3D打印研究較多的材料。適用氧化物陶瓷的3D打印工藝種類也較多，3DP、SLS、FDM、DIW、SLA、SLM、LENS等工藝均可用于氧化物陶瓷的成形?；诜垠w的3DP和SLS利用液態(tài)或低熔點(diǎn)有機(jī)粘結(jié)劑進(jìn)行成形，由于得到素坯致密度較低，在燒結(jié)過程中難以實現(xiàn)完全的致密化，多用于成形多孔陶瓷；SLS與等靜壓技術(shù)結(jié)合的工藝和基于漿料的SLS工藝都可有效提高了素坯的致密度，實現(xiàn)致密氧化物陶瓷的制造。FDM的耗材是陶瓷粉體與熱塑性高分子混合制得的絲材，一般固含量在50vol%以上，但因制絲成本高、制件精度低等原因，F(xiàn)DM工藝很少使用。3D打印所使用的金屬粉末的制備方法主要是霧化法。泰州3D打印設(shè)計服務(wù)</p><p style="text-indent:25px">根據(jù)3D打印方法的不同，要求材料的形態(tài)也有所不同。閔行區(qū)本地3D打印多少錢</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)過全功率點(diǎn)火測試后，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。閔行區(qū)本地3D打印多少錢</p></p><br
