Ukulawulwa Kwezinga lokushisa Okunembile Kwezinhlelo Ze-Laser Nezicelo Zezimboni Kusukela ngo-2002
Ulimi
Ama-laser chiller adlala indima ebalulekile ekuthuthukiseni ukuminyana kwe-sintering nokunciphisa imigqa yesendlalelo ekuphrinteni kwensimbi kwe-3D ngokuzinzisa izinga lokushisa, ukunciphisa ukucindezeleka okushisayo, nokuqinisekisa ukuhlangana kwempushana okufanayo. Ukupholisa okunembayo kusiza ukuvikela amaphutha afana nezimbotshana nokubhowula, okuholela kukhwalithi yokuphrinta ephezulu kanye nezingxenye zensimbi ezinamandla.
Ngokukhula kokwamukelwa kokuphrinta kwensimbi kwe-3D ekukhiqizeni izimboni, isidingo sezingxenye eziphrintiwe zekhwalithi ephezulu siye sakhula. Phakathi kwezinto ezithinta kakhulu imigqa yongqimba ebonakalayo kanye nokuminyana okuncishisiwe kwe-sintering. Lokhu akuthinti nje kuphela ubuhle bendawo kodwa kungase futhi kubonise ukukhubazeka kwangaphakathi okufana nezimbotshana noma ukuhlangana okungaphelele phakathi kwezendlalelo, okufaka engozini ubuqotho bomshini.
Kungani Imigqa Yezendlalelo Eqinile Ibeka I-Lower Sintering Density
Imigqa yesendlalelo eqinile ivamise ukukhombisa ukuhlangana kwe-interlayer okungalungile noma ama-microvoid phakathi kwezingqimba zempushana. Phakathi ne-laser sintering, izimpushana zensimbi kufanele zincibilike futhi ziqine ngokufanayo ukuze zakhe isakhiwo esiminyene, esingenasici. Uma izinto ezincibilikisiwe zingakwazi ukugcwalisa ngokwanele izikhala phakathi kwezinhlayiya, i-porosity yangaphakathi iyanda, inciphisa ngokuqondile ukuminyana kwe-sintering. Ukwengeza, isivinini sokuphrinta esisheshayo noma izimo ezishisayo ezingazinzile zingangenisa ukucindezeleka okushisayo noma komshini, okuholela ekuncibilikeni okungalingani, ukukhishwa kwezinhlayiyana, kanye nokubopha kwezingqimba ezibuthakathaka, konke okunomthelela ekubekweni okubonakalayo kanye nekhwalithi yengxenye esengozini.
Indlela Ama-Laser Chillers Athuthukisa Ngayo Ukuminyana Kwe-Sintering
Ama-laser chiller adlala indima ebalulekile ekusimamiseni indawo eshisayo yamaphrinta ensimbi e-3D. Isibonelo, i-TEYU CWFL-3000 fiber laser chiller ihlanganisa amasekhethi okulawula izinga lokushisa akabili, eyodwa ngeyomthombo we-fiber laser kanye nenye eyokubona. Lokhu kupholisa okunembayo kuqinisekisa izinga lokushisa legumbi elingaguquki, okuvumela izimpushana zensimbi ukuba zincibilike futhi ziqine ngendlela efanayo, ngaleyo ndlela kwandise ukuminyana kwe-sintering.
Ngokuhambisa amanzi abandayo, ama-laser chiller asusa ukushisa okudlulele ezingxenyeni ezibalulekile ezifana nekhanda lokuphrinta ne-substrate yensimbi. Lokhu kunciphisa ukucindezeleka okushisayo, okusiza ukuvimbela ukuguquguquka kwe-powder kanye ne-warping. Ukwengeza, ukupholisa okulawulwayo kusekela ama-gradients okushisa afanele azungeze ichibi elincibilikayo, okukhuthaza ukuqina okuminyene futhi kunciphise ukwakheka kwezimbotshana.
Ama-laser chiller asiza futhi ukucindezela umphumela wokubhowula, isenzakalo lapho izimpushana ezincibilike ngokunganele zakha izinhlayiya eziyindilinga esikhundleni sokuhlangana kungqimba. Ngokulawula izinga lokushisa elizungezile nezinga lokupholisa, ama-chiller akhuthaza ukuhlangana okufanayo kwezimpusha zensimbi, ehlise lesi sici futhi athuthukise ukuminyana kwengxenye yokugcina.
Ukunciphisa Imigqa Yezingqimba Ngama-Laser Chiller
Indawo eshisayo eqinile iwukhiye wokunciphisa imigqa yesendlalelo ekuphrinteni kwensimbi kwe-3D. Ama-laser chiller asiza ukugcina amazinga okushisa afanayo kulo lonke igumbi lokuphrinta, avimbele ukushisa okweqile kwendawo kanye nokuncibilika okungalingani. Lokhu kubangela ukuguquguquka kwesendlalelo okushelelayo, amaphutha ambalwa, kanye nokunemba kobukhulu obuthuthukisiwe. Ngamafuphi, ukuphathwa okushisayo okusebenzayo akuthuthukisi nje kuphela ubuhle bengxenye kodwa futhi kuqinisekisa ubuqotho besakhiwo sezingxenye eziphrintiwe zensimbi ze-3D.
Sikhona ngenxa yakho uma usidinga.
Sicela ugcwalise ifomu ukuze uxhumane nathi, futhi sizokujabulela ukukusiza.

I-TEYU S&A Chiller yasungulwa ngo-2002 ineminyaka engama-23 yesipiliyoni sokukhiqiza okupholile, futhi manje isiqashelwa njengephayona lobuchwepheshe bokupholisa kanye nozakwethu onokwethenjelwa embonini ye-laser.
