▁easily . ▁ 3 D ▁printing ▁gives ▁students ▁a ▁new ▁perspective ▁with ▁top ographic ▁maps . ▁Science ▁students ▁can ▁study ▁cross - sections ▁of ▁internal ▁org ans ▁of ▁the ▁human ▁body ▁and ▁other ▁bi ological ▁spec im ens . ▁And ▁chem istry ▁students ▁can ▁explore ▁ 3 D ▁models ▁of ▁mole cules ▁and ▁the ▁relationship ▁within ▁chemical ▁comp ounds . ▁ ▁According ▁to ▁a ▁recent ▁paper ▁by ▁Kost ak is ▁et ▁al ., ▁ 3 D ▁printing ▁and ▁design ▁can ▁elect r ify ▁various ▁liter a cies ▁and ▁cre ative ▁capac ities ▁of ▁children ▁in ▁accord ance ▁with ▁the ▁spirit ▁of ▁the ▁inter connected , ▁information - based ▁world . ▁ ▁Future ▁applications ▁for ▁ 3 D ▁printing ▁might ▁include ▁creating ▁open - source ▁scientific ▁equipment . ▁ ▁Now ad ays , ▁the ▁demand ▁of ▁ 3 D ▁printing ▁keep ▁on ▁increasing ▁in ▁order ▁to ▁ful fill ▁the ▁dem ands ▁in ▁producing ▁parts ▁with ▁complex ▁geometry ▁at ▁a ▁lower ▁development ▁cost . ▁The ▁increasing ▁dem ands ▁ 3 D ▁printing ▁parts ▁in ▁industry ▁would ▁eventually ▁lead ▁to ▁the ▁ 3 D ▁printed ▁parts ▁repair ing ▁activity ▁and ▁secondary ▁process ▁such ▁as ▁joining , ▁fo aming ▁and ▁cutting . ▁This ▁secondary ▁process ▁need ▁to ▁be ▁developed ▁in ▁order ▁to ▁support ▁the ▁growth ▁of ▁the ▁ 3 D ▁printing ▁application ▁in ▁the ▁future . ▁From ▁the ▁research , ▁F SW ▁is ▁proven ▁able ▁to ▁be ▁used ▁as ▁one ▁of ▁the ▁methods ▁to ▁join ▁the ▁metal ▁ 3 D ▁printing ▁materials . ▁By ▁using ▁proper ▁F
