Ngokweengxelo, abaphandi abavela kwi-Army yase-US kunye neYunivesithi yase-Texas A & M baye baphuhlisa uhlobo olutsha lwezinto zepolymer kuphononongo olujoliswe ekuphuculeni iinqwelomoya ezingapheliyo kunye neemoto zerobhothi ezinokuthi ziguqule kwaye ziziphilise ngokuzenzekelayo.

Kuphando lokuqala, i-3D eprintiweyo ye-epoxy resin imathiriyeli evele okokuqala inokuphendula kwi-stimuli. Abaphandi banethemba lokuba kwixesha elizayo, itekhnoloji ekrelekrele inokufakwa kuyo ukuze ikwazi ukuziqhelanisa ngokuzenzekelayo nokusingqongileyo ngaphandle kokulawulwa lihlabathi langaphandle. Abaphandi bophononongo bathi: "Sinethemba lokwakha inkqubo yezinto eziphathekayo ezinokuthi zibe nesakhiwo, ukuva kunye nemisebenzi yokuphendula ngaxeshanye."

Abaphandi babenombono weqonga elizayo elifanelekileyo kwimishini yomoya kunye nomhlaba, kunye neempawu ze-T-1000 kwi-movie yaseHollywood "Terminator 2." Kulo mboniso bhanyabhanya, iTerminator yenziwe ngentsimbi engamanzi, kwaye ingalo yayo inokuguqulwa ibe sisixhobo sokuhlaba abantu. Iyakwazi nokuzilungisa emva kokubethwa ngumpu we-12-caliber kunye nesiqhushumbisi se-40mm.

Ukuza kuthi ga ngoku, izinto eziveliswe ngabaphandi zinokuphendula kubushushu. Abaphandi baqale bakhetha le sixhobo kuba kulula ukuyisebenzisa kwiimvavanyo zaselabhoratri.

Iipolymers zenziwe ngeeyunithi eziphindaphindayo, njengekhonkco kwikhonkco. Ngokweengxelo, amatyathanga e-polymers athambileyo aqhagamshelwe ngokulula ngokudibanisa. Ubuninzi be-cross-links phakathi kwamaketanga, buphezulu ubulukhuni bezinto eziphathekayo.

Abaphandi bathi: “Inkoliso yezixhobo ezinxibeleleneyo, ingakumbi ezo zenziwe ngoshicilelo lwe-3D, zidla ngokuba nefomu emiselweyo, oko kukuthi, emva kokuba la malungu enziwe, ezo zinto aziyi kunyibilikiswa okanye zinyibilike. Izixhobo ezitsha zineqhosha eliguquguqukayo livumela ukuba litshintshe ukusuka kulwelo ukuya kumatyeli aqinileyo, ngoko ke inokuprintwa nge-3D okanye isetyenziswe kwakhona."

Izitshixo eziguquguqukayo ezinjalo zikhokelela ekuziphatheni kwememori imilo eyodwa, ngoko ke imathiriyeli inokucwangciswa kwaye ivuswe ukuba ibuyele kubume bememori. Oku bhetyebhetye kukhokelela ekufumaneni zombini iipolymer ezithambileyo ezifana nerabha kunye nepolymer enzima, ethwele umthwalo.

Okwangoku, uphando lusekwinqanaba lophando kunye nophuhliso. Iqela laqala ukuzama ukuphuhlisa imathiriyeli yoshicilelo ye-3D enokusetyenziswa kwizicelo zesakhiwo ukwenza amacandelo e-drones kunye ne-rotorcraft.

Abaphandi bathi: "Okwangoku, sinokufikelela ngokulula kwi-80% izinga lokuziphilisa kwiqondo lokushisa, kodwa sinethemba lokufikelela kwi-100%. Umzekelo, ukukhanya Kwixesha elizayo, siza kuphonononga ukubethelela ubuchwephesha obukumgangatho ophantsi ukuvumela imathiriyeli ukuziqhelanisa ngokuzenzekelayo, ngaphandle kwesidingo sabasebenzisi ukuba baqalise inkqubo.

Iphinde yashicilelwa kuluntu lwaseGasgoo
