形狀記憶合金是一類形狀記憶材料，具有在受到某些刺激(如熱、機械或磁性變化)時“記憶”或保留先前形狀的能力。SMA在機器人、汽車、航空航天、生物醫(yī)療等領域有著廣闊的應用前景。NiTi合金是目前發(fā)展比較成熟的SMA，但NiTi合金是難加工材料。將3D打印技術應用于SMA零件的制造，不僅有望解決SMA的加工難題，還能實現(xiàn)傳統(tǒng)工藝無法實現(xiàn)的復雜點陣結構的制造。近年來有不少學者對NiTi合金的SLM工藝進行了探索并取得了一定的成果。目前，SLM打印的NiTi合金零件已經顯示出良好的形狀記憶效應，在8次壓縮循環(huán)后具有約5％的可恢復應變。此外，SLM成形的NiTi樣品的形狀記憶行為與時效工藝高度相關，經350°C—18h時效的樣品展現(xiàn)出了幾乎完美的超彈性。</p><p style="text-indent:25px">傳統(tǒng)水凝膠成形主要依靠模具，無法制造復雜結構；采用3D打印技術成形水凝膠，不僅能夠實現(xiàn)復雜形狀的制造，還能實現(xiàn)復雜孔隙甚至梯度結構的制造，使得3D打印的水凝膠具有傳統(tǒng)制造方式無法獲得的性能。此外，水凝膠中可以加入活細胞，使得3D打印人體部位成為可能。水凝膠的3D打印方法包括光固化成形及直寫成形。用于光固化成形的水凝膠成分與光敏樹脂類似，包括溶劑、單體、交聯(lián)劑、光引發(fā)劑等，可以添加無機填料以實現(xiàn)水凝膠性能的調控。直寫成形是3D打印水凝膠更普及的一種形式。打印時將水凝膠置于注射器中，采用電腦根據設計的結構控制注射器運動及擠出，擠出的水凝膠在外界條件的刺激(溫度、水分、pH、光照等)下固化。為了滿足3D打印的要求，通常要求水凝膠的固化速度足夠快，或者流變性能滿足在打印時不發(fā)生變形，才能實現(xiàn)成功的打印。目前，商業(yè)化的水凝膠打印材料較少，大多數都處于實驗室研制階段。瞄準微米級3D打印技術可以實現(xiàn)微米、亞微米級精度的金屬、介質、光波導等材料的3D打印。</p><div

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，有利于增加燒結驅動。但球形度高的粉體顆粒流動性好，送粉鋪粉均勻，有利于提升產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，粉體是通過直接吸收激光或電子束掃描時的能量而熔化燒結，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。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，因此有利于提高產品的強度和表面質量。但粉體粒度過小時，粉體易發(fā)生粘附團聚，導致粉體流動性下降，影響粉料運輸及鋪粉均勻。所以細粉、粗粉應該以一定配比混合，選擇恰當的粒度與粒度分布以達到預期的成形效果。粉體的工藝性能主要包括松裝密度、振實密度、流動性和循環(huán)利用性能。3D打印材料的性能在很大程度上決定了成形零件的綜合性能。楊浦區(qū)3D打印設計服務</p><p

style="text-indent:25px">3D打印設備進行放大，便可采用混凝土作為耗材進行房屋建筑的3D打印。為保證3D打印建筑的順利實施，3D打印中所使用的混凝土材料比傳統(tǒng)混凝土要求更高，如傳輸和擠出過程中要有足夠的流動性，擠出之后要有足夠的穩(wěn)定性，硬化后要有足夠的強度、剛度和耐久性等。3D打印混凝土不僅可以應用于非線性、自由曲面等復雜形狀建筑的建造，在未來空間探索中有望就地采用資源進行基地的建造。以高嶺土、堇青石等作為原料的多孔或蜂窩陶瓷常用作催化劑載體、過濾裝置，采用SLS或三維噴印成形出宏觀復雜孔道，利用造孔劑進一步獲得微觀多孔結構，可以獲得兼具宏觀及微觀孔隙結構的多孔陶瓷。SLS和3DP均以粉體作為原材料，要求陶瓷粉末的流動性良好，3DP用粉末可以采用噴霧造粒得到，SLS粉末因需加入低熔點粘結劑，可采用機械混合法或覆膜法進行制備。徐匯區(qū)3D打印應用</p></p><br
