Ushicilelo lwe-3D, eyaziwa ngokuba yimveliso eyongezelelweyo, yinkqubo yokudala izinto ezintathu-dimensional ukusuka kwimodeli yedijithali.Ngokungafaniyo neendlela zemveli zokuvelisa, ezibandakanya ukusika izinto ezivela kwibhloko eqinileyo, ushicilelo lwe-3D lwakha into yokugqibela ngokongeza umaleko wezinto ngokwemaleko.Le ndlela yomaleko-ngamaleko inokuvelisa iimilo ezintsonkothileyo kakhulu kunye nezakhiwo ezinokuba nzima okanye zingenzeki ukufikelela kusetyenziswa iindlela zemveli.Ushicilelo lwe-3D lunokusebenzisa izinto ezahlukeneyo, kubandakanya iiplastiki, isinyithi, iiseramikhi, kunye nezinto zebhayoloji ezifana neeseli eziphilayo.Kwangaxeshanye ushicilelo lwe-3D lubonelela ngezinto eziluncedo ezinjengokuchwetheza okukhawulezayo, ukwenziwa ngokwezifiso, ukuchithwa kwenkunkuma yezinto ezincitshisiweyo, kunye nokukwazi ukwenza uyilo oluntsonkothileyo ngokuchaneka okuphezulu.Isetyenziswa ngokubanzi kumashishini amaninzi abandakanya i-aerospace, izithuthi, ukhathalelo lwempilo, ulwakhiwo kunye neemveliso zabathengi kwiprototyping, izixhobo kunye nenxalenye yokusetyenziswa kwenxalenye yokugqibela.Namhlanje eli nqaku liza kwazisa ushicilelo lwe-3D kwiintlobo zabo kunye neempawu.
Eyokuqala i-Fused Deposition Modeling
1.FDM
Umgaqo wokuSebenza:
I-Fused deposition modeling yenye yezona ntlobo zaziwayo zoshicilelo lwe-3D.Isebenza ngokutyhala intambo yeplastiki ngombhobho oshushu.Iplastiki etyhidiweyo ibekwe phantsi umaleko ngokomaleko de loo ndawo igqitywe.Kukho iintlobo ezininzi ezahlukeneyo zefilament ze-3D ezikhoyo - ukusuka kwi-thermoplastics eqinileyo ukuya kwii-elastomers ze-thermoplastic eziguquguqukayo.
Iimbonakalo:
Ukusilela:
1. Isantya sokushicilela siyacotha
2. Imveliso eprintiweyo inobude obungqingqwa bomaleko
Okwesibini enye-UkuKhanya-Ukunyanga
1.SLA
Umgaqo wokuSebenza:
I-Stereolithography yayiyeyokuqala kurhwebo lweteknoloji yoshicilelo lwe-3D.Isebenza ngokuqinisa i-photopolymer yolwelo kwinxalenye yokugqibela ngokulanda i-laser ephezulu yamandla kwipleyiti yokwakha kwimilo yecandelo le-cross-section.Inkqubo iyaqhubeka njengoko umaleko ngamnye olandelayo udibanisa kumaleko angaphambili.Le teknoloji yenza iinxalenye ezineempawu ezichanekileyo kakhulu.
Iimbonakalo:
Ukusilela:
1. Izinto eziphathekayo ziyacaphukisa kwaye zinetyhefu
2. Iyabiza
3. Emva kokushicilela, coca, susa isibiyeli, kunye ne-UV irradiation ukwenzela ukunyanga okwesibini.
2.LCD
Umgaqo wokuSebenza:
Umshicileli we-3D LCD ngumshicileli osebenzisa itekhnoloji yoshicilelo lwentlaka ephilisa ukukhanya.Ngokungafaniyo nabashicileli be-3D bemveli abaprinta umaleko ngokomaleko, abashicileli be-LCD be-3D basebenzisa ukukhanya kwe-UV ukuprinta iileya zonke ngaxeshanye.Oku kuthetha ukuba ushicilelo lwe-3D olune-3D LCD umshicileli lukhawuleza kwaye luchaneke ngakumbi kunabanye abashicileli be-3D.
Yintoni eyenza i-LCD 3D abashicileli bahluke kwezinye iindidi zabashicileli be-3D, njenge-DLP okanye i-SLA abashicileli, ngumthombo wabo wokukhanya.Abashicileli be-LCD be-3D basebenzisa ii-UV LCD njengemithombo yokukhanya.Ngoko ke, ukukhanya okuvela kwipaneli ye-LCD kubetha indawo yokusebenza ngokuthe ngqo ngendlela efanayo.Ngenxa yokuba oku kukhanya akukwandi, ukugqwethwa kwe-pixel kuncinci kakhulu kumcimbi woshicilelo lwe-LCD.
Iimbonakalo:
Ukusilela:
1. Isikrini se-LCD sinobomi obufutshane kwaye kufuneka sitshintshwe emva kokushicilela amawaka eeyure.
2. Izinto eziphathekayo ziyacaphukisa kwaye zinetyhefu.
Okwesithathu omnye-umgubo Fusion
SLS, SLM
Umgaqo wokuSebenza:
I-laser sintering ekhethiweyo isebenza ngokubeka umaleko weplastiki engumgubo kunye nokulandelela icandelo elinqamlezayo lenxalenye ngelaser.I-laser inyibilikisa umgubo kwaye iyixube.Omnye umaleko wepowder yeplastiki ubekwe phezu komgangatho wangaphambili, kwaye i-laser inyibilikisa i-cross-sectional shape ngelixa idibanisa kuluhlu lwangaphambili.Ukuba kukho iziteshi zokuphuma kwipowder enganyibilikiyo, inkqubo inokuvelisa iindawo ezichanekileyo ezinokuthi ziprintwe endaweni.
Iimbonakalo:
Ukusilela:
1. Iindleko zibiza kakhulu
2. I-Warping ithanda ukwenzeka xa kushicilelwa iindawo ezinobungakanani obukhulu
3. Kukho ivumba elikhulu xa usebenza
Isishwankathelo
Eli nqaku lazisa itekhnoloji yoshicilelo ye-3D eyahlukeneyo kwaye ifaka ngokweentlobo zoshicilelo lwe-3D.Ukufunda ngakumbi malunga neentlobo zoshicilelo lwe-3D kunye nokunye malunga nokwenza iimveliso zakho eziprintiweyo ze-3D,Qhagamshelana nathi.
