Uburyo bushya bwo gucapa bwa 3D butuma habaho imiterere igoye kandi bugatuma habaho imyanda mike

Ibikoresho bifasha kumva, ibirinda akanwa, ibikoresho by'amenyo, n'ibindi bikoresho byakozwe neza akenshi ni ibyakozwe mu icapiro rya 3D. Ibi bikoresho bikunze gukorwa hifashishijwe icyuma gipima amenyo (vat photopolymerization).—ubwoko bw'icapiro rya 3D rikoresha imiterere y'urumuri kugira ngo rishyireho ishusho kandi rikomeze resin, urwego rumwe rumwe.

Iyi gahunda kandi ikubiyemo gucapa ibikoresho by'inyubako bivuye mu bikoresho bimwe kugira ngo ibicuruzwa bikomeze kuguma mu mwanya wabyo nk'uko'byacapwe. Iyo ibicuruzwa bimaze gushingwa neza, ibishyigikizo bikurwaho n'intoki kandi akenshi bigajugunywa nk'imyanda idakoreshwa.

Injeniyeri za MIT zabonye uburyo bwo kurenga iyi ntambwe ya nyuma yo kurangiza, mu buryo bushobora kwihutisha cyane igikorwa cyo gucapa mu buryo bwa 3D. Bakoze resin ihinduka ubwoko bubiri butandukanye bw'ibintu bikomeye, bitewe n'ubwoko bw'urumuri ruyimurikiraho: Umucyo wa ultraviolet uvura resin ikaba ikintu gikomeye cyane, mu gihe urumuri rugaragara ruhindura resin imwe ikaba ikintu gikomeye gishobora gushonga mu bintu bimwe na bimwe.

Itsinda ryashyize resin nshya icyarimwe ku miterere y'urumuri rwa UV kugira ngo ikore imiterere ikomeye, ndetse n'imiterere y'urumuri rugaragara kugira ngo ikore imiterere.'Ibikoresho by'inyongera. Aho kugira ngo bacemo ibice by'inyongera bitonze, bashyizemo ibikoresho byacapwe mu gikoresho cyashongesheje ibikoresho by'inyongera, bigahishura igice gikomeye kandi cyacapwe na UV.

Ibikoresho bishobora gushonga mu buryo butandukanye butagira ingaruka ku biribwa, harimo n'amavuta y'abana. Igishimishije ni uko ibikoresho bishobora gushonga no mu kintu cy'ingenzi cy'amazi cya resin y'umwimerere, nk'agace k'urubura mu mazi. Ibi bivuze ko ibikoresho byakoreshejwe mu gucapa ibikoresho bishobora kongera gukoreshwa: Iyo imiterere yacapwe'Ibikoresho bishyigikira bishonga, urwo ruvange rushobora kuvangwa rukongera rugashyirwa muri resin nshya hanyuma rugakoreshwa mu gucapa ibice bikurikira.—hamwe n'ibishyigikizo byabyo bishobora gushonga.

Abashakashatsi bakoresheje uburyo bushya mu gucapa inyubako zigoye, harimo ibikoresho bikora neza n'udupira duto.
