Ubuhanga bushya bwakozwe nabashakashatsi bo mubusuwisi bushobora kunoza uburyo bwo gucapa 3D ibirahure

Mubikoresho byose bishobora gucapurwa 3D, ikirahure kiracyari kimwe mubikoresho bigoye.Icyakora, abahanga mu kigo cy’ubushakashatsi cy’ikigo cy’ikoranabuhanga cy’Ubusuwisi cya Zurich (ETH Zurich) barimo gukora ibishoboka ngo bahindure iki kibazo binyuze mu ikoranabuhanga rishya kandi ryiza.

Ubu birashoboka gucapa ibintu byibirahure, kandi uburyo bukoreshwa cyane burimo gukuramo ikirahure cyashongeshejwe cyangwa guhitamo ifu ya ceramic ya laser yo kubihindura mubirahure.Iyambere isaba ubushyuhe bwinshi bityo ibikoresho birwanya ubushyuhe, mugihe ibyanyuma bidashobora kubyara ibintu bigoye cyane.Ubuhanga bushya bwa ETH bugamije kunoza izo nenge zombi.

Irimo ibibyimba bifotora bigizwe na plastike yamazi na molekile kama bihujwe na molekile irimo silikoni, mu yandi magambo, ni molekile ceramic.Ukoresheje inzira ihari yitwa digitale yumucyo, resin ihura nicyitegererezo cyumucyo ultraviolet.Ahantu hose urumuri rukubita resin, monomer ya plastike izahuza kugirango ikore polymer ikomeye.Polimeri ifite labyrint-imeze imbere, kandi umwanya uri muri labyrint wuzuye molekile ceramic.

Ikintu cyavuyeho gifite ibipimo bitatu noneho kirasa ku bushyuhe bwa 600 ° C kugirango gitwike polymer, hasigara ceramic gusa.Mu kurasa kwa kabiri, ubushyuhe bwo kurasa bugera kuri 1000 ° C, kandi ceramic yegeranye mu kirahure kibonerana.Ikintu kigabanuka cyane iyo gihinduwe mubirahure, nikintu kigomba gusuzumwa mugushushanya.

Abashakashatsi bavuze ko nubwo ibintu byakozwe kugeza ubu ari bito, imiterere yabyo iragoye.Byongeye kandi, ingano ya pore irashobora guhindurwa muguhindura ubukana bwimirasire ya ultraviolet, cyangwa indi miterere yikirahure irashobora guhinduka mukuvanga borate cyangwa fosifate mubisigarira.

Ikwirakwizwa ry’ibirahure rikomeye mu Busuwisi rimaze kwerekana ko rishishikajwe no gukoresha ikoranabuhanga, risa nk’ikoranabuhanga ririmo gutezwa imbere mu kigo cy’ikoranabuhanga cya Karlsruhe mu Budage.
