Yintoni Efuna Ukupholisa Kwiprinta Ye-3D? Icacisiwe I-SLS, I-SLM, I-SLA kunye ne-DLP

Ukuprinta kwe-3D kugubungela uluhlu olubanzi lwetekhnoloji, kwaye iimfuno zabo zokuphola zingahluka kakhulu. I-SLS, i-SLM/DMLS, i-SLA kunye ne-DLP zonke zisebenzisa iindlela ezahlukeneyo zokwakha iinxalenye ze-layer nge-layer. Ngokuxhomekeke kuyilo lwenkqubo, umthombo ophambili wobushushu unokuba yi-CO₂ laser, i-fiber laser, i-UV laser okanye injini yokukhanya ye-UV. Ngoko ke, yintoni ngokwenene efuna ukuphola ngaphakathi kwiprinta ye-3D? Impendulo ayixhomekekanga kakhulu kwigama leprinta kodwa ixhomekeke ngakumbi kumthombo wokukhanya, inkqubo ye-optical kunye neemeko zokusebenza.

Ukuprinta kwe-SLS 3D: Ukuphola kwe-CO₂ okanye i-Fiber Laser
I-Selective Laser Sintering (SLS) isebenzisa i-laser ukucoca ngokukhetha umaleko we-polymer powder ngelaphu ngalinye. Ngokuxhomekeke kuyilo lomatshini, iinkqubo ze-SLS zinokusebenzisa ii-CO₂ lasers okanye ii-fiber lasers.
Iilaser ze-CO₂ zisetyenziswa kakhulu kwiinkqubo ze-polymer SLS zemveli, ngelixa amaqonga amatsha angasebenzisa neelaser zefayibha ze-1064 nm. Kuyo nayiphi na indlela, ilaser kunye nezinto ezinxulumene nayo zinokuvelisa ubushushu ngexesha lokusebenza ixesha elide kwaye zinokufuna ukupholisa okuzinikeleyo.
Ukusetyenziswa kwehlabathi lokwenyani: Isixhobo sokutshiza izimboni i-TEYU CW-6000 sisetyenziselwa pholisa i-laser ye-CO₂ ye-100W kwinkqubo yokuprinta ye-SLS 3D.

Ukuprinta kwe-SLM/DMLS 3D: Ukuphola kwe-Fiber Laser kunye ne-Optics
I-Selective Laser Melting (SLM) kunye ne-Direct Metal Laser Sintering (DMLS) zisebenzisa ii-laser ukunyibilikisa okanye ukunyibilikisa umaleko we-metal powder umaleko ngamnye.
Iilaser zefayibha ezinamandla aphezulu zisetyenziswa kakhulu kwimveliso yezithako zesinyithi, ngelixa uyilo lwe-multi-laser lunokungenisa imithwalo eyongezelelweyo yobushushu njengoko inani lemithombo yelaser lisanda. Ngoko ke, iilaser kunye nezixhobo ze-optical zifuna ulawulo oluzinzileyo lobushushu ngexesha lemijikelo yokuprinta eyandisiweyo.
Ezinye ii-wavelengths ze-laser nazo ziyahlolwa ukuze kusetyenzwe ngesinyithi ngokukhethekileyo. Umzekelo, ii-laser eziluhlaza ezimalunga ne-515 nm zinokubonelela ngeenzuzo zezinto ezikhanyayo kakhulu ezifana ne-copper kunye ne-copper alloys.
Usetyenziso lwehlabathi lokwenyani: A TEYU CWFL-3000 i-fiber laser chiller isetyenziswa nenkqubo yokuvelisa izongezo zesinyithi ezine-laser ezimbini.

Ukuprinta kwe-SLA 3D: Ukupholisa i-UV Laser
I-Stereolithography (SLA) isebenzisa ukukhanya ukunyanga i-resin yolwelo ibe ziingqimba eziqinileyo. Ngokuxhomekeke kuyilo lweprinta, umthombo wokukhanya unokwahluka.
Ezinye iinkqubo ze-SLA zoshishino zisebenzisa ii-laser ze-UV ezingama-355 nm, apho i-laser kunye nezinto ezibonakalayo zizinto ezibalulekileyo ekupholiseni. Ulawulo lobushushu oluzinzileyo lunokunceda ukugcina iimeko zokusebenza ezihambelanayo ngexesha lokuprinta okwandisiweyo.
Ukusetyenziswa kwehlabathi lokwenyani: A TEYU CWUL-05 Isitshizi se-laser ye-UV ibonelela ngokupholisa i-3W, 355 nm UV laser kwiprinta ye-SLA 3D.

Ukuprinta kwe-DLP 3D: Ukupholisa i-UV Light Engine
I-Digital Light Processing (DLP) 3D printing isebenzisa ukukhanya okucwangcisiweyo ukunyanga umaleko wonke we-resin ngaxeshanye. Inkqubo yayo yokukhanya yahlukile kwi-SLA esekelwe kwi-laser, apho injini yokukhanya kunye nezixhobo zokukhanya zidlala indima ephambili.
Ngokuxhomekeke kuyilo lwenkqubo, iiprinta ze-DLP zingasebenzisa imithombo yokukhanya ye-UV okanye ekufutshane ne-UV, kuquka neenkqubo ze-405 nm. Ubushushu obuveliswa yinjini yokukhanya kunye nezinto ezibonakalayo bunokuchaphazela uzinzo lokusebenza kwaye ke ngoko bunokufuna ukupholisa okuzinikeleyo.
Ukusetyenziswa kwehlabathi lokwenyani: I-TEYU CWUL-05 UV laser chiller isetyenziselwa ukupholisa injini yesibane se-UV engama-405 nm kwinkqubo yokuprinta ye-DLP 3D.

Indlela yokukhetha iChiller yePrinta ye-3D
Itekhnoloji yokuprinta ye-3D yeyona ndawo iphambili xa ukhetha isisombululo sokupholisa.
I-chiller kufuneka ihambelane nenxalenye yokwenyani evelisa ubushushu kunye neemeko zayo zokusebenza. Izinto ezibalulekileyo ekufuneka ziqwalaselwe ziquka:
* Umthamo wokupholisa: wanele ukususa ubushushu obuveliswa yilaser okanye umthombo wokukhanya.
* Uzinzo lobushushu: kubalulekile ekusebenzeni rhoqo ngexesha lemijikelo emide yokuprinta.
* Ukuhamba komoya kunye noxinzelelo: kufuneka kuhlangatyezwane neemfuno zecandelo elipholileyo.
* Indawo yokusebenza: ubushushu obuphakathi kunye neemeko zokufakela zinokuchaphazela ukusebenza kokupholisa.
* Umsebenzi oqhubekayo: ukuprinta okuqhubekayo kwemizi-mveliso kunokufuna ukupholisa okuzinzileyo ixesha elide.
* Umngcipheko wokufuma: ubushushu be-coolant kufuneka bukhethwe ngokufanelekileyo kwindawo yokusebenza.

Ngamafutshane, akukho sisombululo sinye sokupholisa kwiprinta nganye ye-3D. I-chiller efanelekileyo ixhomekeke kwinto evelisa ubushushu, into ekufuneka ipholiswe, kunye nendlela esebenza ngayo inkqubo.
Ukususela kwi-CO₂ kunye ne-fiber lasers kwi-SLS kunye nokuveliswa kwezinto ezongeziweyo zesinyithi ukuya kwi-UV lasers kunye neenjini zokukhanya kwi-SLA kunye ne-DLP, TEYU inikezela ngezisombululo ze-closed-loop water chiller kwiindidi ezahlukeneyo zezicelo zokuprinta ze-3D.
