I-Selective Laser Melting (SLM) iguqule ukukhiqizwa kwesimanje ngokuvumela ukukhiqizwa kwezingxenye zensimbi eziyinkimbinkimbi kakhulu, ezingasindi, neziqinile.

Emgogodleni walobu buchwepheshe kukhona izakhi ezibonakalayo ze-SLM, eziqinisekisa ukuthi i-laser beam ilethwa ngokunemba okuphezulu, ukuzinza, nokusebenza kahle. Ngaphandle kwezinhlelo zokubona ezithuthukisiwe, yonke inqubo ye-SLM izohlupheka ngenxa yokunemba okuncishisiwe, ukukhiqiza okunensayo, kanye nekhwalithi engahambisani.

Kungani Izingxenye Ze-Optical Zibalulekile ku-SLM

Inqubo ye-SLM incike kulaser enamandla amakhulu ukuze incibilikise izendlalelo ezinhle zempushana yensimbi. Lokhu kudinga ukuthi i-beam ibunjwe kahle, iqondiswe, futhi igxile ngaso sonke isikhathi. Izingxenye ze-Optical—njengamalensi e-F-theta, izandisi zemishayo, amamojula ahlanganayo, amawindi okuvikela, namakhanda esithwebuli se-galvo—zidlala indima ebalulekile ekuqinisekiseni ukuthi i-laser igcina ikhwalithi yayo ukusuka emthonjeni kuya ekuqondisweni. Lezi zingxenye zisebenza ndawonye ukuze kuncishiswe ukulahlekelwa, ukulawula usayizi wendawo, futhi kunikwe amandla ukuskena okunembayo kuwo wonke umbhede oyimpuphu.

Izingxenye Ezibalulekile Zokubona ze-SLM

1.F-Theta Scan Lens
Amalensi e-F-theta abalulekile ezinhlelweni ze-SLM. Baqinisekisa ukuthi indawo ye-laser ihlala ifana futhi ingahlanekezelwe kuyo yonke inkundla yokuskena. Ngokugcina ukugxila okungaguquki, lawa ma-lens avumela ukuncibilika okunembile kwesendlalelo se-powder ngayinye, ukuthuthukisa ukunemba nokuphindaphinda.

2.Beam Expanders
Ukuze kuzuzwe usayizi wendawo wekhwalithi ephezulu, izandisi ze-beam zilungisa ububanzi be-laser beam ngaphambi kokuthi ifinyelele kuma-optics agxilile. Lokhu kusiza ukunciphisa ukwehlukana nokugcina ukuminyana kwamandla, okubalulekile ekukhiqizeni izindawo ezibushelelezi, ezingenasici ezingxenyeni eziphrintiwe ze-3D.

3.QBH Collimating Modules
Amamojula ahlanganisayo aqinisekisa ukuthi i-laser beam iphuma ngendlela ehambisanayo, ilungele ukubona ezansi nomfula. Ezinhlelweni ze-SLM, ukungqubuzana okuzinzile kuthinta ngokuqondile ukujula kokugxila kanye nokufana kwamandla, okukwenza kube yingxenye ebalulekile yokuzuza ikhwalithi yokwakha engaguquki.

4.Amalensi okuvikela kanye namaWindows
Njengoba i-SLM ihlanganisa izimpushana zensimbi nokusebenzisana kwe-laser enamandla amakhulu, izakhi ezibonakalayo kufanele zivikelwe ngokumelene ne-spatter, imfucumfucu, nokucindezeleka okushisayo. Amafasitela avikelayo avikela ama-optics abizayo ekulimaleni, andisa ukuphila kwawo kanye nokunciphisa izindleko zokuwalungisa.

5.Galvo Scanner Heads
Amakhanda esikena alawula ukunyakaza okusheshayo kwe-laser beam kuwo wonke umbhede oyimpuphu. Izinhlelo ze-galvo ezinesivinini esikhulu nezinembayo ziqinisekisa ukuthi i-laser ilandela izindlela ezihleliwe ngokunembile, okubalulekile ekwakheni imininingwane emihle namajiyometri ayinkimbinkimbi.

Izinzuzo Zezingxenye Zekhwalithi Ephezulu Ze-Optical ku-SLM

Ukunemba Okuthuthukisiwe Kokuphrinta - Ukugxila okunembe kanye nokulethwa kwezigxobo okuzinzile kuthuthukisa ukunemba kobukhulu bezingxenye eziphrintiwe.

Ukusebenza Okuthuthukisiwe - Ama-optics athembekile anciphisa isikhathi sokuphumula esibangelwa ukungahambi kahle noma ukulimala, ukugcina ukukhiqizwa kungaguquki.

Ukonga Izindleko - I-Optics evikelayo inciphisa imvamisa yokushintshwa, kuyilapho izingxenye ezihlala isikhathi eside zinweba impilo yonke yomshini.

I-Material Flexibility - Ngama-optics athuthukisiwe, imishini ye-SLM ingacubungula izinhlobonhlobo zezinsimbi, okuhlanganisa i-titanium, i-aluminium, insimbi engagqwali, nama-superalloy asekelwe ku-nickel.

I-Scalability - Izisombululo zekhwalithi ephezulu zivumela abakhiqizi ukuthi balinganise ukukhiqizwa ngenkathi begcina imiphumela ephindaphindwayo.

Izicelo ze-SLM Enezici Ezithuthukile Zokubona

Izingxenye ezibonayo zinika amandla i-SLM ukuthi isebenzele izimboni lapho ukunemba nokusebenza okubalulekile kubalulekile:

I-Aerospace - Ama-turbine blades angasindi kanye nezingxenye zesakhiwo.

Ezokwelashwa - Izifakelo ezenziwe ngokwezifiso, izakhi zamazinyo, namathuluzi okuhlinza.

Izimoto - Izingxenye zenjini ezisebenza kahle kakhulu kanye nemiklamo yesakhiwo engasindi.

Amandla - Izingxenye zamaturbine egesi, amaseli kaphethiloli, namasistimu wamandla avuselelekayo.

Njengomhlinzeki oholayo wezingxenye ze-laser optical, uCarman Haas uhlinzeka ngohlu olubanzi lwezixazululo eziklanyelwe ngqo i-SLM kanye nokukhiqiza okungeziwe. Iphothifoliyo yomkhiqizo wethu ihlanganisa:

Amalensi wokuskena we-F-theta athuthukiselwe ama-laser anamandla amakhulu.

Izandisi ze-beam ezilungisekayo zokusetha okuguquguqukayo.

Amamojula ahlanganisayo futhi agxilile anokuqina okuphakeme.

Amalensi okuvikela ahlala isikhathi eside ukuze andise impilo yesistimu.

Amakhanda esithwebuli se-galvo anesivinini esiphezulu ukuze asebenze kahle kakhulu.

Ingxenye ngayinye ibhekana nokuhlolwa kwekhwalithi okuqinile ukuze kuqinisekiswe ukwethembeka ngaphansi kwezimo zezimboni ezinzima. Ngobungcweti kukho kokubili ukuklama nokukhiqiza, uCarman Haas usekela amakhasimende ngezisombululo eziklanyelwe ezihlangabezana nezidingo ezithile zohlelo lokusebenza.

Emhlabeni wokukhiqiza okungeziwe, izingxenye ezibonakalayo ze-SLM azizona nje izesekeli—ziyisisekelo sokunemba, ukusebenza kahle, nokwethembeka. Ngokutshala imali kuma-optics ekhwalithi ephezulu, abakhiqizi bangavula amandla aphelele e-SLM, okuholela ekusebenzeni okuthuthukisiwe, izindleko eziphansi, nokuncintisana okuthuthukisiwe emakethe yomhlaba. UCarman Haas uzibophezele ekuletheni izixazululo ezisezingeni eliphezulu ezinikeza amandla isizukulwane esilandelayo sobuchwepheshe bokuphrinta be-3D.
