Yini Edinga Ukupholisa Kuphrinta Ye-3D? Kuchazwa I-SLS, I-SLM, I-SLA kanye ne-DLP

Ukuphrinta kwe-3D kuhlanganisa ubuchwepheshe obubanzi, futhi izidingo zabo zokupholisa zingahluka kakhulu. I-SLS, i-SLM/DMLS, i-SLA kanye ne-DLP zonke zisebenzisa izindlela ezahlukene zokwakha izingxenye ungqimba ngengqimba. Kuye ngomklamo wesistimu, umthombo oyinhloko wokushisa kungaba yi-laser ye-CO₂, i-laser yefayibha, i-laser ye-UV noma injini yokukhanya ye-UV. Ngakho-ke, yini ngempela edinga ukupholisa ngaphakathi kwephrinta ye-3D? Impendulo ayixhomekile kakhulu egameni lephrinta kodwa incike kakhulu emthonjeni wokukhanya, ohlelweni lwe-optical kanye nezimo zokusebenza.

Ukuphrinta kwe-SLS 3D: Ukupholisa kwe-CO₂ noma i-Fiber Laser
I-Selective Laser Sintering (SLS) isebenzisa i-laser ukuze ikhethe ungqimba lwe-polymer powder ngesendlalelo. Kuye ngokwakhiwa komshini, izinhlelo ze-SLS zingasebenzisa ama-CO₂ lasers noma ama-fiber lasers.
Ama-laser e-CO₂ asetshenziswe kabanzi ezinhlelweni ze-polymer SLS zendabuko, kuyilapho amapulatifomu amasha angasebenzisa nama-laser e-fiber angu-1064 nm. Kunoma yikuphi ukucushwa, i-laser nezingxenye ezihlobene nayo zingakhiqiza ukushisa ngesikhathi sokusebenza isikhathi eside futhi zingadinga ukupholisa okuzinikele.
Ukusetshenziswa kwangempela: I-TEYU CW-6000 industrial chiller isetshenziselwa pholisa i-laser ye-CO₂ engu-100W ohlelweni lokuphrinta lwe-SLS 3D.

Ukuphrinta kwe-3D kwe-SLM/DMLS: Ukupholisa kwe-Fiber Laser kanye ne-Optics
I-Selective Laser Melting (SLM) kanye ne-Direct Metal Laser Sintering (DMLS) zisebenzisa ama-laser ukuncibilikisa noma ukucwilisa ungqimba lwempuphu yensimbi ngengqimba.
Ama-laser e-fiber anamandla amakhulu asetshenziswa kabanzi ekukhiqizeni izengezo zensimbi, kuyilapho izakhiwo ze-laser eziningi zingaletha imithwalo eyengeziwe yokushisa njengoba inani lemithombo ye-laser landa. Ngakho-ke, izingxenye ze-laser kanye ne-optical zidinga ukuphathwa okuzinzile kokushisa ngesikhathi semijikelezo yokuphrinta ende.
Amanye amaza okukhanya kwe-laser nawo ayahlolwa ukuze kucutshungulwe insimbi ekhethekile. Isibonelo, ama-laser aluhlaza azungeze ama-515 nm anganikeza izinzuzo zezinto ezikhanyisa kakhulu njengethusi kanye ne-alloys yethusi.
Uhlelo lokusebenza lomhlaba wangempela: A TEYU CWFL-3000 i-fiber laser chiller isetshenziswa nohlelo lokukhiqiza izithasiselo zensimbi olusebenzisa i-laser ekabili.

Ukuphrinta kwe-SLA 3D: Ukupholisa nge-UV Laser
I-Stereolithography (i-SLA) isebenzisa ukukhanya ukuze ikhethe ngokukhetha i-resin ewuketshezi ibe yizingqimba eziqinile. Kuye ngokwakhiwa kwephrinta, umthombo wokukhanya ungahluka.
Ezinye izinhlelo ze-SLA zezimboni zisebenzisa ama-laser e-UV angu-355 nm, lapho i-laser kanye nezingxenye ze-optical kuyizinhloso ezibalulekile zokupholisa. Ukulawula izinga lokushisa okuzinzile kungasiza ekugcineni izimo zokusebenza ezihambisanayo ngesikhathi sokuphrinta okunwetshiwe.
Uhlelo lokusebenza lwangempela: A TEYU CWUL-05 Isishisi se-laser ye-UV inikeza ukupholisa kwe-3W, 355 nm UV laser kuphrinta ye-SLA 3D.

Ukuphrinta kwe-DLP 3D: Ukupholisa Injini Yokukhanya Kwe-UV
Ukuphrinta kwe-3D kwe-Digital Light Processing (DLP) kusebenzisa ukukhanya okuveziwe ukuze kuphulukiswe ungqimba lonke lwe-resin ngesikhathi esisodwa. Uhlelo lwayo lokukhanya luhlukile ku-SLA esekelwe ku-laser, lapho injini yokukhanya kanye nezingxenye zokukhanya zidlala indima ebalulekile.
Kuye ngomklamo wesistimu, amaphrinta e-DLP angasebenzisa imithombo yokukhanya ye-UV noma eseduze ne-UV, kufaka phakathi izinhlelo ze-405 nm. Ukushisa okukhiqizwa yinjini yokukhanya kanye nezingxenye ze-optical kungathinta ukuzinza kokusebenza ngakho-ke kungadinga ukupholisa okuzinikele.
Isicelo sangempela: I-TEYU CWUL-05 UV laser chiller isetshenziselwa ukupholisa injini yokukhanya ye-UV engu-405 nm ohlelweni lokuphrinta lwe-DLP 3D.

Indlela Yokukhetha I-Chiller Yephrinta Ye-3D
Ubuchwepheshe bokuphrinta be-3D buyisiqalo nje lapho ukhetha ikhambi lokupholisa.
I-chiller kufanele ifaniswe nengxenye yangempela ekhiqiza ukushisa kanye nezimo zayo zokusebenza. Izinto ezibalulekile okufanele uzicabangele zifaka:
* Amandla okupholisa: anele ukususa ukushisa okukhiqizwa yi-laser noma umthombo wokukhanya.
* Ukuqina kwezinga lokushisa: kubalulekile ekusebenzeni njalo phakathi kwemijikelezo yokuphrinta emide.
* Ukugeleza nokucindezela: kufanele kuhlangabezane nezidingo zengxenye epholile.
* Indawo yokusebenza: izinga lokushisa elizungezile kanye nezimo zokufaka kungathinta ukusebenza kokupholisa.
* Umjikelezo womsebenzi: ukuphrinta okuqhubekayo kwezimboni kungadinga ukupholisa okuzinzile isikhathi eside.
* Ingozi yokufiphala: izinga lokushisa le-coolant kufanele likhethwe ngokufanele endaweni yokusebenza.

Ngamafuphi, asikho isisombululo esisodwa sokupholisa sephrinta ngayinye ye-3D. I-chiller efanele incike kulokho okudala ukushisa, okudinga ukuphola, kanye nendlela uhlelo olusebenza ngayo.
Kusukela kuma-CO₂ nama-fiber laser ku-SLS kanye nokukhiqizwa kwezengezo zensimbi kuya kuma-UV lasers kanye nezinjini zokukhanya ku-SLA kanye ne-DLP, TEYU inikeza izixazululo ze-closed-loop water chiller zezinhlelo zokusebenza ezahlukene zokuphrinta ze-3D.
