Electron　beam　melting　(EBM)　is　a　metal　powder　bed　fusion　additive　manufacturing　(AM)　technology　that　is　widely　used　for　making　three-dimensional　(3D)　objects　by　adding　materials　layer　by　layer.　EBM　is　a　very　complex　thermal　process　which　involves　several　physical　phenomena　such　as　moving　heat　source,　material　state　change,　and　material　deposition.　Conventionally,　these　phenomena　are　implemented　using　in-house　codes　or　embedding　some　user　subroutines　in　commonly　used　commercial　software　packages,　like　Abaqus,　which　generally　requires　considerable　expertise.　Fortunately,　recent　versions　of　Abaqus　offer　a　new　plugin　tool,　AM　Modeler,　which　provides　a　rather　new　and　user-friendly　method　for　performing　additive　manufacturing　process　simulation.　In　this　work,　taking　Ti-6Al-4V　as　the　particular　example,　we　present　all　the　details　of　the　finite　element　(FE)　implementation　of　both　Abaqus　user　subroutines　and　AM　Modeler　plugin　for　thermal　analysis　of　EBM　additive　manufacturing　process.　The　melting　pool　shape　and　temperature　profiles　were　predicted　and　verified　against　existing　literature　data.　A　3D　FE　model　was　also　developed　to　capture　the　heat　transfer　features　in　a　real　manufacturing　process　for　printing　a　particular　3D　object,　＇AM＇　characters,　validating　the　capability　of　the　proposed　methods.　To　facilitate　future　design　and　thermal　analysis　of　EBM　process　and　to　promote　the　use　of　AM　Modeler　plugin,　the　source　codes　including　Abaqus　user　subroutines　DFLUX　and　UMATHT　as　well　as　Python　scripts　for　implementing　AM　Modeler　are　made　available　and　could　be　downloaded　from　https://github.com/Dr-Ning-An/ebm-abaqus.　©　2021　Elsevier　Ltd
