style="text-indent:25px">覆膜砂是鑄造產(chǎn)業(yè)中常用的造型材料，但傳統(tǒng)的覆膜砂需要借助模具進(jìn)行成形，模具的形狀復(fù)雜程度有限且生產(chǎn)成本高，不適合小批量鑄件的生產(chǎn)。3D打印技術(shù)可以實(shí)現(xiàn)鑄型(芯)的整體制造，省去了傳統(tǒng)鑄型(芯)多塊拼接的過程，節(jié)約時(shí)間成本的同時(shí)，提高了鑄件精度。玻璃是一種非晶態(tài)材料，其成形方式與陶瓷材料不同，由于玻璃在成形時(shí)處于熔融態(tài)，通常以吹制、壓制、拉制、輥壓或鑄造等方式進(jìn)行成形。較為成功的玻璃3D打印工藝是FDM工藝，打印時(shí)熔融玻璃儲(chǔ)存在高溫坩堝中，通過擠出頭擠出冷凝成形。該工藝可以實(shí)現(xiàn)透光性良好的玻璃制品，但由于目前玻璃打印的條件較為苛刻，尚未獲得普及。3D打印用金屬粉體需要采用純度較高的金屬粉體原料。上海金屬材料3D打印哪家便宜</p><p
