Ngokwemibiko, abacwaningi abavela e-US Army kanye ne-Texas A&M University baye bahlakulela uhlobo olusha lwezinto ezibonakalayo ze-polymer ocwaningweni oluhloselwe ukuthuthukisa izindiza ezinganamuntu zesikhathi esizayo kanye nezimoto zamarobhothi, ezingakhubaza kanye nokuziphilisa ngokuzenzakalelayo.

Ocwaningweni lwakuqala, okokusebenza kwe-epoxy resin okuphrintiwe kwe-3D okuvela okokuqala kungaphendula ku-stimuli. Abacwaningi banethemba lokuthi esikhathini esizayo, ubuchwepheshe obuhlakaniphile bungafakwa kuyo ukuze ikwazi ukuzivumelanisa nemvelo ngaphandle kokulawulwa amazwe angaphandle. Abacwaningi balolu cwaningo bathi: "Sithemba ukwakha uhlelo lwezinto ezibonakalayo ezingase zibe nesakhiwo, ukuzwa kanye nemisebenzi yokuphendula ngesikhathi esisodwa."

Abacwaningi babone ngeso lengqondo inkundla yesikhathi esizayo efanelekayo emoyeni nasemhlabathini, enezici ze-T-1000 ku-movie yaseHollywood "Terminator 2." Kule movie eshisa izikhotha, i-Terminator yenziwe ngensimbi ewuketshezi, futhi ingalo yayo ingashintshwa ibe yisikhali sokugwaza abantu. Iyakwazi futhi ukuzilungisa ngemuva kokushaywa isibhamu sohlobo lwe-12 kanye nesiqhumane sebhomu esingu-40mm.

Kuze kube manje, izinto ezithuthukiswe abacwaningi zingasabela emazingeni okushisa. Abacwaningi baqale bakhetha le nto ngoba kulula ukuyisebenzisa ekuhlolweni kwaselabhorethri.

Ama-polymers enziwe ngamayunithi aphindaphindayo, njengezixhumanisi zeketango. Ngokwemibiko, amaketanga ama-polymer athambile axhumeke kancane kuphela ngokuxhumanisa. Ukuxhumana okuningi phakathi kwamaketanga, kuphakama ubulukhuni bempahla.

Abacwaningi bathi: “Izinto eziningi ezixhumene kakhulu, ikakhulukazi lezo ezenziwe ukuphrinta kwe-3D, zivame ukuba nefomu elingaguquki, okungukuthi, lapho izingxenye sezakhiwe, izinto zokwakha ngeke zicutshungulwe noma zincibilike. Izinto ezisetshenziswayo ezintsha zinokhiye oguquguqukayo ziyivumela ukuthi ishintshe kusukela koketshezi iye kokuqinile izikhathi eziningi, ngakho ingaphrintwa nge-3D noma igaywe kabusha."

Okhiye abanjalo abaguqukayo baphumela ekuziphatheni kwenkumbulo yomumo ohlukile, ngakho-ke okokusebenza kungahlelwa futhi kucushwe ukuze kubuyele esimweni sememori. Lokhu kuvumelana nezimo kuholela ekutholeni kokubili i-polymer ethambile efana nerabha kanye ne-polymer yepulasitiki eqinile, ethwele umthwalo.

Njengamanje, ucwaningo lusesigabeni socwaningo nentuthuko. Ithimba laqala ukuzama ukuthuthukisa izinto zokuphrinta ze-3D ezingasetshenziswa ezinhlelweni zokusebenza ukwenza izingxenye ze-drones ngisho ne-rotorcraft.

Abacwaningi bathi: "Okwamanje, singafinyelela kalula izinga lokuziphilisa elingu-80% lezinto ekamelweni lokushisa, kodwa sithemba ukuthi sizofinyelela ku-100%. Ngaphezu kwalokho, sithemba nokuthi izinto zingaphendula kwezinye izisusa ngaphandle kwezinga lokushisa. . Isibonelo, ukukhanya Ngokuzayo, sizohlola ukushumeka ubuchwepheshe obusezingeni eliphansi ukuze sivumele izinto ezisetshenziswayo ukuthi zizijwayeze ngokuzenzakalela, ngaphandle kwesidingo sokuthi abasebenzisi baqale inqubo."
