Ukwenziwa koNcedo: Ukuprinta kwe-3D kwi-Circular Economy

Intshayelelo

Isaci esidumileyo esithi, “Khathalela umhlaba kwaye uza kukunyamekela. Tshabalalisa umhlaba kwaye uza kukutshabalalisa” sibonisa ukubaluleka kokusingqongileyo kwethu. Ukuze silondoloze kwaye sikhusele okusingqongileyo kwingozi engaphezulu, kuya kufuneka sigxile ekuphuhliseni uzinzo. Singakufezekisa oku ngokusebenzisa uqoqosho olujikelezayo ngokusebenzisa iinkqubo zokwenziwa kwezinto ezongezelelweyo (AM) kuneenkqubo zokwenziwa eziqhelekileyo (CM) (Velenturf kunye nePurnell). I-AM - eyaziwa ngokuba yi-3D printing - inciphisa inkunkuma, isebenzisa izixhobo ezinobuhlobo nokusingqongileyo, kwaye inciphisa ukusetyenziswa kwamandla, okunokwenza ukuba ibe sisitshixo sekamva elizinzileyo kokusingqongileyo.

Inciphisa inkunkuma kunye nongcoliseko

Izinto eziluhlaza ezimbalwa ziyachithwa kwaye ungcoliseko oluncinci luveliswa xa sisebenzisa i-AM ngaphezu kwe-CM. Ngokutsho koprofesa u-MR Khosravani kunye no-T. Reinicke beYunivesithi yaseSiegen, “[i-AM] ivumela inkunkuma encinci kwinkqubo yokuvelisa njengoko zonke iinxalenye zeemodeli, iiprototypes, izixhobo, iimolds, kunye neemveliso zokugqibela zenziwa kwinkqubo enye” (iKhosravani kunye neReinicke). Yonke into yenziwe umaleko ngomnyeleko ukusuka ezantsi ukuya phezulu, umatshini wokuprinta we-3D uza kusebenzisa kuphela izinto ezifunekayo kwicandelo lokugqibela kunye nezakhiwo ezincinci ezixhasayo. Ngokungafaniyo nokuveliswa kwemveli, iimveliso zenziwa ngaphandle kwesidingo sokuhlanganiswa kwi-AM. Oku kuthetha ukuba iigesi zegreenhouse ezikhutshwa rhoqo ngexesha lenkqubo yokuthutha ziya kuthintelwa, nto leyo enciphisa amanqanaba ongcoliseko.

Ukonga Amandla

Ngaphandle kokunciphisa inkunkuma nokusebenzisa izixhobo ezinobuhlobo nokusingqongileyo, i-AM iyasebenza kakuhle kwimizi-mveliso. I-AM iphucula ukusetyenziswa kwamandla ngelixa inciphisa ukusetyenziswa kwepetroli ngexesha lokwenziwa kwemveliso (Javaid et al.).

Ngaphezu koko, iWhite House ikwabhengeze ukuba “Ngenxa yokuba iteknoloji yokongeza yakha ukusuka ezantsi ukuya phezulu endaweni yokuthabatha izinto ezilahliweyo, ezi teknoloji zinokunciphisa iindleko zezixhobo ngama-90 ekhulwini kwaye zinciphise ukusetyenziswa kwamandla ngesiqingatha” (IWhite House). Ukuba onke amashishini anako ukutshintsha inkqubo yawo yokuvelisa yangoku ngenkqubo ye-AM enza njalo, singasondela kakhulu ekufikeleleni ekuzinzeni.

Isiphelo

Ukusebenza kakuhle kwendalo yeyona nto ibalulekileyo ekuzinzeni, kwaye ukunciphisa ukusetyenziswa kwamandla kunye nemveliso yenkunkuma kunokukhokelela ekumisweni okukhulu kokufudumala kwehlabathi (Javaid et al.). Ukuba ixesha elininzi kunye nezixhobo zityalwa kuphando kunye nophuhliso lwe-AM, ekugqibeleni sinokukwazi ukuvelisa uqoqosho olujikelezayo olusebenzayo.
