Kodi N’chiyani Chimafunika Kuziziritsa mu Printer ya 3D? Kufotokozedwa kwa SLS, SLM, SLA ndi DLP

Kusindikiza kwa 3D kumakhudza ukadaulo wosiyanasiyana, ndipo zofunikira zawo zoziziritsira zimatha kukhala zosiyana kwambiri. SLS, SLM/DMLS, SLA ndi DLP zonse zimagwiritsa ntchito njira zosiyanasiyana popanga zigawo ndi zigawo. Kutengera kapangidwe ka makina, gwero lofunikira la kutentha lingakhale CO₂ laser, fiber laser, UV laser kapena injini ya kuwala kwa UV. Ndiye, kodi ndi chiyani chomwe chimafunika kuziziritsa mkati mwa chosindikizira cha 3D? Yankho lake silidalira kwambiri dzina la chosindikizira koma limadalira kwambiri gwero la kuwala, makina owonera, ndi momwe zimagwirira ntchito.

Kusindikiza kwa SLS 3D: CO₂ kapena Fiber Laser Cooling
Selective Laser Sintering (SLS) imagwiritsa ntchito laser kuti isungunule ufa wa polymer wosanjikiza ndi wosanjikiza. Kutengera kapangidwe ka makina, makina a SLS angagwiritse ntchito CO₂ lasers kapena fiber lasers.
Ma laser a CO₂ akhala akugwiritsidwa ntchito kwambiri m'makina achikhalidwe a polymer SLS, pomwe nsanja zatsopano zitha kugwiritsanso ntchito ma laser a ulusi a 1064 nm. Mu kapangidwe kalikonse, laser ndi zida zina zokhudzana nazo zimatha kupanga kutentha panthawi yogwira ntchito nthawi yayitali ndipo zingafunike kuziziritsa kwapadera.
Kugwiritsa ntchito zenizeni: Chotsukira cha mafakitale cha TEYU CW-6000 chimagwiritsidwa ntchito kuziziritsa laser ya CO₂ ya 100W mu makina osindikizira a SLS 3D.

Kusindikiza kwa 3D kwa SLM/DMLS: Kuziziritsa kwa Fiber Laser ndi Optics
Kusungunula kwa Laser Yosankhidwa (SLM) ndi Direct Metal Laser Sintering (DMLS) zimagwiritsa ntchito ma lasers kusungunula kapena kusungunula ufa wachitsulo wosanjikiza ndi wosanjikiza.
Ma laser amphamvu kwambiri amagwiritsidwa ntchito kwambiri popanga zowonjezera zachitsulo, pomwe mapangidwe a ma laser ambiri amatha kuyambitsa mafuta owonjezera pamene kuchuluka kwa magwero a laser kumawonjezeka. Chifukwa chake, ma laser ndi zigawo za kuwala zimafuna kuyang'aniridwa kokhazikika kwa kutentha panthawi yayitali yosindikiza.
Mafunde ena a laser akufufuzidwanso kuti agwiritsidwe ntchito pokonza zitsulo mwapadera. Mwachitsanzo, ma laser obiriwira okwana 515 nm angapereke ubwino pazinthu zowala kwambiri monga mkuwa ndi aloyi a mkuwa.
Ntchito zenizeni padziko lapansi: A TEYU CWFL-3000 choziziritsira cha laser cha fiber imagwiritsidwa ntchito ndi makina opangira zowonjezera zitsulo za laser ziwiri.

Kusindikiza kwa SLA 3D: Kuziziritsa kwa UV Laser
Stereolithography (SLA) imagwiritsa ntchito kuwala kuti ipange utomoni wamadzimadzi kukhala zigawo zolimba. Kutengera kapangidwe ka chosindikizira, gwero la kuwala limasiyana.
Makina ena a SLA amafakitale amagwiritsa ntchito ma laser a 355 nm UV, komwe ma laser ndi zida zowunikira ndizofunikira kwambiri pakuziziritsa. Kuwongolera kutentha kokhazikika kungathandize kusunga magwiridwe antchito nthawi yayitali.
Kugwiritsa ntchito zenizeni: A TEYU CWUL-05 Choziziritsira cha laser cha UV imapereka kuziziritsa kwa laser ya 3W, 355 nm UV mu chosindikizira cha SLA 3D.

Kusindikiza kwa DLP 3D: Kuziziritsa kwa Injini ya Kuwala kwa UV
Kusindikiza kwa 3D kwa Digital Light Processing (DLP) kumagwiritsa ntchito kuwala koyezedwa kuti kuchiritse utomoni wonse nthawi imodzi. Dongosolo lake la kuwala limasiyana ndi la SLA yochokera ku laser, pomwe injini ya kuwala ndi zigawo zoyezera zimagwira ntchito yofunika kwambiri.
Kutengera kapangidwe ka makina, makina osindikizira a DLP amatha kugwiritsa ntchito magwero a kuwala kwa UV kapena pafupi ndi UV, kuphatikiza makina a 405 nm. Kutentha komwe kumapangidwa ndi injini yamagetsi ndi zida zamagetsi kumatha kusokoneza kukhazikika kwa magwiridwe antchito ndipo chifukwa chake kungafunike kuziziritsa kodzipereka.
Kugwiritsa ntchito zenizeni: Choziziritsira cha laser cha TEYU CWUL-05 UV chimagwiritsidwa ntchito kuziziritsa injini ya kuwala kwa UV ya 405 nm mu makina osindikizira a DLP 3D.

Momwe Mungasankhire Chiller cha Printer ya 3D
Ukadaulo wosindikiza wa 3D ndi poyambira posankha njira yoziziritsira.
Choziziritsira chiyenera kufananizidwa ndi gawo lenileni lopanga kutentha ndi momwe limagwirira ntchito. Zinthu zofunika kuziganizira ndi izi:
* Mphamvu yoziziritsira: yokwanira kuchotsa kutentha komwe kumapangidwa ndi laser kapena gwero la kuwala.
* Kukhazikika kwa kutentha: ndikofunikira kuti ntchito igwire bwino ntchito nthawi yayitali yosindikiza.
* Kuyenda ndi kupanikizika: ziyenera kukwaniritsa zofunikira za gawo lozizira.
* Malo ogwirira ntchito: kutentha kwa malo ndi momwe zimakhazikitsidwira zimatha kukhudza magwiridwe antchito ozizira.
* Ntchito yogwira ntchito: kusindikiza kosalekeza kwa mafakitale kungafunike kuziziritsa kosalekeza kwa nthawi yayitali.
* Chiwopsezo cha kuzizira: kutentha kwa choziziritsira kuyenera kusankhidwa moyenera malinga ndi malo ogwirira ntchito.

Mwachidule, palibe njira imodzi yokha yoziziritsira makina pa chosindikizira chilichonse cha 3D. Choziziritsira choyenera chimadalira chomwe chimapanga kutentha, chomwe chiyenera kuziziritsidwa, komanso momwe makina amagwirira ntchito.
Kuyambira CO₂ ndi ma fiber laser mu SLS ndi kupanga zowonjezera zitsulo mpaka ma UV laser ndi ma light engine mu SLA ndi DLP, TEYU imapereka njira zoziziritsira madzi zotsekedwa pa ntchito zosiyanasiyana zosindikizira za 3D.
