Ukuphrinta kwe-3D, okwaziwa nangokuthi ukukhiqiza okungeziwe, kuyinqubo yokudala izinto ezinezinhlangothi ezintathu kusuka kumamodeli edijithali.Ngokungafani nezindlela zendabuko zokukhiqiza ezikhiphayo, ezibandakanya ukusika impahla ebhulokhini eliqinile, ukuphrinta kwe-3D kwakha into yokugcina ngokwengeza ungqimba lwempahla ngongqimba.Le ndlela yokwendlalela ngesendlalelo ingaveza ubujamo obuyinkimbinkimbi kakhulu nezakhiwo okungaba nzima noma okungenzeki ukuzifeza kusetshenziswa izindlela zendabuko.Ukuphrinta kwe-3D kungasebenzisa izinto ezahlukahlukene, kufaka phakathi amapulasitiki, izinsimbi, izitsha zobumba, ngisho nezinto zebhayoloji njengamaseli aphilayo.Ngesikhathi esifanayo ukuphrinta kwe-3D kunikeza izinzuzo ezifana ne-prototyping esheshayo, ukwenza ngokwezifiso, ukuchithwa kwempahla encishisiwe, kanye nekhono lokudala imiklamo eyinkimbinkimbi ngokunemba okuphezulu.Isetshenziswa kabanzi ezimbonini eziningi ezihlanganisa i-aerospace, ezezimoto, ezokunakekelwa kwempilo, ezokwakha kanye nemikhiqizo yabathengi yokwenza i-prototyping, ithuluzi kanye nokukhiqizwa kwengxenye yokusetshenziswa ekugcineni.Namuhla lesi sihloko sizokwethula ukuphrinta kwe-3D kusuka ezinhlotsheni nezici zabo.
Imodeli yokuqala ye-Fused Deposition yokuqala
1.FDM
Umgomo wokusebenza:
I-Fused deposition modelling ingenye yezinhlobo ezaziwa kakhulu zokuphrinta kwe-3D.Isebenza ngokuphusha imicu yepulasitiki ngombhobho oshisayo.Ipulasitiki encibilikisiwe ibe isibekwa phansi ungqimba ngongqimba kuze kube yilapho ingxenye iphelele.Kunezinhlobo eziningi ezahlukene ze-3D filament ezitholakalayo - kusukela kuma-thermoplastics aqinile kuya kuma-thermoplastic elastomer aguquguqukayo.
Izici:
Ububi:
1. Isivinini sokuphrinta sihamba kancane
2. Umkhiqizo ophrintiwe unokuphakama kongqimba obukhulu
Okwesibili okukodwa-Ukuphulukisa Ukukhanya
1.SLA
Umgomo wokusebenza:
I-Stereolithography kwaba ubuchwepheshe bokuphrinta be-3D bokuqala obutholakala kwezohwebo.Isebenza ngokuqinisa i-photopolymer ewuketshezi engxenyeni yokugcina ngokulandela ngomkhondo i-laser enamandla amakhulu epuleti lokwakha elisesimweni sengxenye enqamulayo.Inqubo iyaqhubeka njengoba isendlalelo ngasinye esilandelayo sihlanganisa isendlalelo sangaphambilini.Lobu buchwepheshe budala izingxenye ezinezici ezinembe kakhulu.
Izici:
Ububi:
1. Impahla iyacasula futhi inobuthi kancane
2. Kuyabiza
3. Ngemva kokuphrinta, hlanza, khipha ubakaki, nemisebe ye-UV ukuze ukwelapha okwesibili.
2.LCD
Umgomo wokusebenza:
Iphrinta ye-3D LCD iyiphrinta esebenzisa ubuchwepheshe bokuphrinta be-resin ephilisa ukukhanya.Ngokungafani namaphrinta endabuko e-3D aphrinta isendlalelo ngokwesendlalelo, amaphrinta e-LCD 3D asebenzisa ukukhanya kwe-UV ukuze aphrinte zonke izendlalelo ngesikhathi esisodwa.Lokhu kusho ukuthi ukuphrinta kwe-3D ngephrinta ye-3D LCD kuyashesha futhi kunembe kakhulu kunamanye amaphrinta e-3D.
Yini eyenza amaphrinta e-LCD 3D ahluke kwezinye izinhlobo zamaphrinta e-3D, njengamaphrinta e-DLP noma e-SLA, umthombo wawo wokukhanya.Amaphrinta e-LCD 3D asebenzisa amalungu afanayo e-UV LCD njengemithombo yokukhanya.Ngakho-ke, ukukhanya okuvela kuphaneli ye-LCD kushaya indawo yokusebenza ngokuqondile ngendlela efanayo.Ngenxa yokuthi lokhu kukhanya akukhuli, ukuhlanekezela kwe-pixel akuyona inkinga yokuphrinta kwe-LCD.
Izici:
Ububi:
1. Isikrini se-LCD sinempilo emfushane futhi sidinga ukushintshwa ngemva kokuphrinta izinkulungwane zamahora.
2. Impahla iyacasula futhi inobuthi kancane.
I-Third One-Powder Fusion
I-SLS, i-SLM
Umgomo wokusebenza:
I-laser sintering ekhethiwe isebenza ngokubeka ungqimba lwepulasitiki eyimpuphu nokulandela ingxenye enqamulayo yengxenye ngelaser.I-laser incibilikisa impushana futhi iyixube.Olunye ungqimba lwempushana yepulasitiki lubekwe phezu kongqimba lwangaphambilini, futhi i-laser incibilikisa umumo we-cross-sectional ngenkathi ihlanganisa ungqimba lwangaphambilini.Uma kukhona iziteshi zokuphuma ze-powder engancibilikisiwe, inqubo ingakhiqiza izingxenye ezinembayo eziphezulu ezingaphrintwa endaweni.
Izici:
Ububi:
1. Izindleko zibiza kakhulu
2. I-Warping ijwayele ukwenzeka lapho uphrinta izingxenye ezinosayizi omkhulu
3. Kukhona iphunga elikhulu uma usebenza
Isifinyezo
Lesi sihloko sethula ubuchwepheshe bokuphrinta be-3D obuhlukile futhi sifaka ngokwezinhlobo zokuphrinta kwe-3D.Ukuze ufunde kabanzi mayelana nezinhlobo zokuphrinta ze-3D nokuningi mayelana nokwenza kahle imikhiqizo yakho ephrintiwe ye-3D,Xhumana nathi.
