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(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。</p><p

style="text-indent:25px">按照聚合體系劃分，可以分為自由基聚合和陽(yáng)離子聚合，兩者的聚合機(jī)理和依靠的活性基團(tuán)各不相同。自由基聚合依靠光敏樹脂中的不飽和雙鍵進(jìn)行聚合反應(yīng)，而陽(yáng)離子聚合依靠光敏樹脂中的環(huán)氧基團(tuán)進(jìn)行聚合反應(yīng)。自由基聚合體系固化速度快，原料成本低，但在空氣中存在一定程度的氧阻聚效應(yīng)，會(huì)對(duì)固化性能及零件性能產(chǎn)生影響；陽(yáng)離子聚合體系則無氧阻聚效應(yīng)，固化收縮小甚至無收縮，但對(duì)水分很敏感，且原料成本較高，所以目**D打印中使用的光敏樹脂以自由基聚合體系為主。3D打印用光敏樹脂主要采用的是自由基聚合的丙烯酸酯體系。商業(yè)化的丙烯酸酯有多種類型，需要根據(jù)不同的需求對(duì)配方進(jìn)行調(diào)整。打印機(jī)通過讀取文件中的橫截面信息。湖州3D打印哪家比較好</p><p

按照材料種類劃分，3D打印金屬材料可以分為鐵基合金、鈦及鈦基合金、鎳基合金、鈷鉻合金、鋁合金、銅合金及貴金屬等。鐵基合金是3D打印金屬材料中研究較早、較深入的一類合金，較常用的鐵基合金有工具鋼、316L不銹鋼、M2高速鋼、H13模具鋼和15-5PH馬氏體時(shí)效鋼等。鐵基合金使用成本較低、硬度高、韌性好，同時(shí)具有良好的機(jī)械加工性，特別適合于模具制造。3D打印隨形水道模具是鐵基合金的一大應(yīng)用，傳統(tǒng)工藝異形水道難以加工，而3D打印可以控制冷卻流道的布置與型腔的幾何形狀基本一致，能提升溫度場(chǎng)的均勻性，有效降低產(chǎn)品缺陷并提高模具壽命。什么是3D打印服務(wù)報(bào)價(jià)</p></p><br
