style="text-indent:25px">3D鐳雕技術(shù)又稱(chēng)3D激光藝雕技術(shù)，是利用高能量密度的激光束作用于目標(biāo)，利用高能量，極短脈沖的激光，讓物質(zhì)瞬間氣化，不傷及周?chē)镔|(zhì)，并可精確的控制作用的深度，使目標(biāo)表面發(fā)生物理或化學(xué)的變化，它代替了傳統(tǒng)的鑿子和刻刀，對(duì)工件多余的部分去除雕刻，從而獲得可見(jiàn)圖案的雕刻方式。 3D激光藝雕技術(shù)主要應(yīng)用于鋁、鋅、銅、鎳、鋼等多種金屬材料及不銹鋼金屬外觀上實(shí)現(xiàn)立體凹凸雕刻和平面細(xì)紋雕刻，成像層次平滑無(wú)階梯，實(shí)現(xiàn)了真正意義上的3D高質(zhì)量，大深度的紋理金屬板材，可直接在金屬材質(zhì)上實(shí)現(xiàn)各種圖案與色彩，克服了以前激光刻膜在腐蝕中有人工干預(yù)、多次化學(xué)腐蝕帶來(lái)的復(fù)雜性和不確定性。主要用于冰箱、空調(diào)和手機(jī)等產(chǎn)品的外觀上，使產(chǎn)品顯得更加高較大氣。松江區(qū)3D打印哪個(gè)品牌好3D打印所使用的金屬粉末的制備方法主要是霧化法。</p><div

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(shù)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(shù)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(wú)氧阻聚效應(yīng)，固化收縮小甚至無(wú)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(shù)脂以自由基聚合體系為主。3D打印用光敏樹(shù)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(lèi)型，需要根據(jù)不同的需求對(duì)配方進(jìn)行調(diào)整。</p><p

PCL是一種無(wú)毒、低熔點(diǎn)的熱塑性塑料，PCL絲材主要作為兒童使用的3D打印筆的耗材，因成形溫度較低(80~100°C)而有較高的安全性。值得一提的是，PCL具有優(yōu)異的生物相容性和降解性，可以作為生物醫(yī)療中組織工程支架的材料，通過(guò)摻雜納米羥基磷灰石等材料還能夠改善力學(xué)性能及生物相容性。此外PCL材料還具有一定的形狀記憶效應(yīng)，在4D打印方面有一定的潛力。TPU是一種具有良好彈性的熱塑性聚合物，其硬度范圍寬且可調(diào)，有一定的耐磨性、耐油性，適用于鞋材、個(gè)人消費(fèi)品、工業(yè)零件等的制造。結(jié)合3D打印技術(shù)可以制造出傳統(tǒng)成形工藝難以制造的復(fù)雜多孔結(jié)構(gòu)，使得制件擁有獨(dú)特且可調(diào)控的力學(xué)性能。采用SLS工藝打印的多孔結(jié)構(gòu)TPU鞋墊的彈性性能和使用強(qiáng)度已達(dá)到市場(chǎng)使用標(biāo)準(zhǔn)。3D打印上打印透明光敏樹(shù)脂需要研磨透明光敏樹(shù)脂，棒的位置仍然良好。松江區(qū)3D打印哪個(gè)品牌好</p><p
