Indlela iiLaser Chillers eziphucula ngayo uxinano lweSintering kunye nokunciphisa imigca yeLayer kwiMetal 3D Printing

Njengoko kwamkelwa ngokukhula koshicilelo lwe-metal 3D kwimizi-mveliso, imfuno yezinto eziprintiweyo ezisemgangathweni inyukile. Phakathi kweengxaki ezixhalabisayo kukho imigca ebonakalayo kunye noxinano olunciphileyo lwe-sintering. Oku akuchaphazeli nje ubuhle bomphezulu kodwa kunokubonisa iziphene zangaphakathi ezifana nee-pores okanye ukudibana okungaphelelanga phakathi kweeleya, nto leyo ebeka emngciphekweni ukuthembeka koomatshini.

Kutheni iMigca Enzima YeeLayer Inciphisa Uxinano Lwe-Sintering

Imigca enzima yeeleya idla ngokubonisa ukudibana okungahambi kakuhle kweeleya okanye ii-microvoids phakathi kweeleya zepowder. Ngexesha lokusila nge-laser, iipowder zesinyithi kufuneka zinyibilike kwaye ziqine ngokulinganayo ukuze zenze isakhiwo esixineneyo, esingenaziphene. Ukuba izinto ezinyibilikisiweyo azikwazi ukuzalisa ngokwaneleyo izithuba phakathi kwee-particles, i-porosity yangaphakathi iyanda, nto leyo enciphisa ngokuthe ngqo uxinano lwe-sintering. Ukongeza, isantya sokuprinta esikhawulezayo okanye iimeko zobushushu ezingazinzanga zinokubangela uxinzelelo olugqithisileyo lobushushu okanye loomatshini, nto leyo ekhokelela ekunyibilikeni okungalinganiyo, ukufuduka kwee-particles, kunye nokubophelelana kweeleya ezibuthathaka, zonke ezi zinto zinegalelo ekubekweni kweeleya ezibonakalayo kunye nomgangatho wenxalenye obuthathaka.

Indlela iiLaser Chillers eziphucula ngayo uxinano lweSintering

Ii-laser chillers zidlala indima ebalulekileyo ekuzinziseni imeko-bume yobushushu yeeprinta ze-metal 3D. Umzekelo, i-TEYU CWFL-3000 fiber laser chiller ineesekethe zokulawula ubushushu ezimbini, enye yeyomthombo we-fiber laser kwaye enye yeyokukhanya. Oku kupholisa okuchanekileyo kuqinisekisa ubushushu obufanayo begumbi, okuvumela iipowder zesinyithi ukuba zinyibilike kwaye ziqine ngokulinganayo, ngaloo ndlela zonyusa uxinano lwe-sintering.

Ngokujikelezisa amanzi abandayo, ii-laser chillers zisusa ubushushu obugqithisileyo kwizinto eziphambili ezifana nentloko yokushicilela kunye ne-substrate yesinyithi. Oku kunciphisa uxinzelelo lobushushu, olunceda ekuthinteleni ukufuduka komgubo kunye nokugoba. Ukongeza, ukupholisa okulawulwayo kuxhasa i-gradients yobushushu efanelekileyo ejikeleze ichibi elinyibilikayo, okukhuthaza ukuqina okuxineneyo kunye nokunciphisa ukwakheka kweembobo.

Ii-laser chillers zikwanceda ekucinezeleni isiphumo se-balling, into apho ii-powders ezinganyibilikanga ngokwaneleyo zenza amasuntswana angqukuva endaweni yokunamathela kumaleko. Ngokulawula ubushushu be-atmospheric kunye nesantya sokupholisa, ii-chillers zikhuthaza ukuhlanganiswa okufanayo kwee-powders zesinyithi, zinciphisa esi siphene kwaye zonyusa uxinano lwamacandelo okugqibela.

Ukunciphisa imigca yeeleya ngeeLaser Chillers

Indawo ezinzileyo yobushushu ibalulekile ekunciphiseni imigca yomaleko kushicilelo lwe-3D lwesinyithi. Ii-laser chillers zinceda ukugcina amaqondo obushushu afanayo kulo lonke igumbi lokuprinta, zithintela ubushushu obuphezulu bendawo kunye nokunyibilika okungalinganiyo. Oku kubangela utshintsho oluthambileyo lomaleko, iziphene ezimbalwa, kunye nokuchaneka okuphuculweyo kobukhulu. Ngamafutshane, ulawulo olusebenzayo lobushushu aluphuculi kuphela ubuhle benxalenye kodwa luqinisekisa ukuthembeka kwesakhiwo sezinto eziprintiweyo ze-3D zesinyithi.
