Nhọrọ Laser Melting (SLM) na-eji irradiation laser ike dị elu ma na-agbaze ntụ ntụ kpamkpam iji mepụta ụdị 3D, nke bụ teknụzụ nrụpụta igwe nwere ike ime. A na-akpọkwa ya teknụzụ ịgbado ọkụ laser. N'ozuzu, a na-ewere ya dị ka alaka nke teknụzụ SLS.
N'ime usoro mbipụta SLS, ihe igwe eji eme ihe bụ ntụ ntụ agwakọta nke igwe edozichara yana ihe mgbaze dị ala ma ọ bụ ihe molekụla. A na-agbaze ihe dị ala na-agbaze ma nnukwu ntụ ntụ ígwè adịghị agbaze n'ime usoro ahụ. were Anyị na-eji ihe agbaze eme ihe iji nweta mmetụta nke njikọta na ịkpụzi.

Usoro niile nke mbipụta SLM na-amalite site n'iberibe data CAD 3D na ịtụgharị data 3D n'ime ọtụtụ data 2D. Ụdị data 3D CAD na-abụkarị faịlụ STL. A na-ejikwa ya n'ọtụtụ ebe na usoro obibi akwụkwọ 3D ndị ọzọ nwere akwa. Anyị nwere ike ibubata data CAD n'ime sọftụwia slicing wee tọọ paramita njirimara dị iche iche, ma tinyekwa ụfọdụ akara njikwa obibi akwụkwọ. N'ime usoro mbipụta SLM, nke mbụ, a na-ebipụta akwa oyi akwa n'otu n'otu na mkpụrụ ahụ, mgbe ahụ, a na-enweta mbipụta nke 3D site na mmegharị nke axis Z.
A na-eme usoro obibi akwụkwọ niile n'ime akpa mechiri emechi jupụtara na argon gas inert ma ọ bụ nitrogen iji belata ọdịnaya oxygen na 0.05%. Ụdị ọrụ nke SLM bụ ijikwa galvanometer iji ghọta irradiation laser nke ntụ ntụ, kpo oku metal ruo mgbe agbazere ya kpamkpam. Mgbe okpokoro irradiation nke otu ọkwa gwụchara, tebụl ahụ na-agbada, na usoro tiling na-arụ ọrụ tile ọzọ, na laser .Mgbe emechara nke irradiation nke oyi akwa ọzọ, a na-agbaze oyi akwa ọhụrụ nke ntụ ntụ ma jikọta ya na oyi akwa gara aga, A na-emeghachi usoro a na-emecha mechaa 3D geometry.
