Ukuphumelela Okusha ku-Femtosecond Laser 3D Printing: Izindleko Eziphansi Zamalaza Akabili

Ososayensi baseNyuvesi yasePurdue basanda kwenza impumelelo ebalulekile kubuchwepheshe bokuphrinta be-laser 3D be-femtosecond. Bakha indlela entsha ye-photon-photon polymerization ehlanganisa ngobuhlakani amalaser amabili wokuphrinta kwe-3D. Ngokwenza kanjalo, bakwazile ukuphrinta izakhiwo ze-3D eziyinkimbinkimbi, zokucaca okuphezulu ngenkathi behlisa amandla e-laser ye-femtosecond ngo-50%. Lokhu kusungula akuthembisi nje kuphela ukunciphisa kakhulu izindleko zokuphrinta kwe-3D enokulungiswa okuphezulu kodwa futhi kwandise ukusetshenziswa okungaba khona kwalobu buchwepheshe emikhakheni eyahlukene.

Ngokukhethekile, ithimba locwaningo lihlanganise i-laser yokukhanya ebiza kancane ebiza kancane ne-infrared pulsed femtosecond laser, ehlisa kakhulu amandla e-laser we-femtosecond adingekayo. Ukuze kuthuthukiswe ibhalansi phakathi kwama-lasers amabili, bathuthukise imodeli entsha yezibalo ukuze baqonde kangcono izinqubo ze-photochemical kanye nokubala ngokunembile imiphumela ye-synergistic ye-excitation yama-photon amabili kanye ne-single-photon. Imiphumela yokuhlola ibonise ukuthi ezakhiweni ze-2D, le ndlela yehlise amandla e-laser we-femtosecond adingekayo ngo-80%, kanye nezakhiwo ze-3D, cishe ngo-50%.

Sekukonke, le nqubo entsha ayinciphisi kuphela izindleko zokuphrinta kwe-laser 3D ye-femtosecond kodwa futhi igcina amandla ayo okulungiswa okuphezulu. Lokhu kuthuthukiswa okudabukisayo kulindeleke ukuthi kugqugquzele izicelo ezintsha emikhakheni efana ne-biomedicine, micro-robotics, kanye namadivayisi we-micro-optical. Ngaphezu kwalokho, njengoba indlela entsha ingahlanganiswa kalula ezinhlelweni zokuphrinta ze-laser 3D ezikhona ze-femtosecond, kungenzeka isheshise ukwamukelwa kwayo kanye nokwanda kuzo zonke izimboni.

Njengomkhiqizi okhilimu obandayo ohamba phambili oneminyaka engu-22 yesipiliyoni sokupholisa izimboni kanye ne-laser, i-TEYU S&A i-Chiller ilandelela ngokuqhubekayo intuthuko kubuchwepheshe be-laser futhi yandisa imigqa yethu yomkhiqizo opholile ukuze ihlangabezane nezidingo zokupholisa eziguqukayo.
