3D kusindikiza, yomwe imadziwikanso kuti zowonjezera zowonjezera, ndi njira yopangira zinthu zitatu-dimensional kuchokera ku zitsanzo za digito.Mosiyana ndi njira zachikhalidwe zochepetsera, zomwe zimaphatikizapo kudula zinthu kuchokera pachidacho cholimba, kusindikiza kwa 3D kumapanga chinthu chomaliza powonjezera zinthu zosanjikiza ndi zosanjikiza.Njira yosanjikiza ndi yosanjikiza iyi imatha kupanga mawonekedwe ovuta kwambiri ndi mapangidwe omwe angakhale ovuta kapena osatheka kukwaniritsa pogwiritsa ntchito njira zachikhalidwe.Kusindikiza kwa 3D kumatha kugwiritsa ntchito zinthu zosiyanasiyana, kuphatikiza mapulasitiki, zitsulo, zoumba, komanso zida zamoyo monga ma cell amoyo.Panthawi imodzimodziyo kusindikiza kwa 3D kumapereka ubwino monga kufotokozera mofulumira, kusintha makonda, kuchepa kwa zinthu zowonongeka, komanso luso lopanga mapangidwe ovuta kwambiri.Amagwiritsidwa ntchito kwambiri m'mafakitale ambiri kuphatikiza zakuthambo, magalimoto, chisamaliro chaumoyo, zomangamanga ndi zinthu zogula popanga ma prototyping, zida ndi ntchito zomaliza.Lero nkhaniyi iwonetsa kusindikiza kwa 3D kuchokera kumitundu ndi mawonekedwe awo.
Choyamba-Fused Deposition Modelling
1.FDM
Ntchito mfundo:
Fused deposition modelling ndi imodzi mwa mitundu yodziwika bwino ya kusindikiza kwa 3D.Zimagwira ntchito pokankhira ulusi wapulasitiki kudzera mumphuno yotentha.Pulasitiki yosungunukayo amayalidwa mosanjikiza ndi wosanjikiza mpaka gawolo litamalizidwa.Pali mitundu yambiri yamitundu yosiyanasiyana ya 3D yomwe ilipo - kuchokera ku thermoplastics yolimba kupita ku ma elastomer osinthika a thermoplastic.
Mawonekedwe:
Kuipa:
1. Liwiro losindikiza limachedwa
2. Chosindikizidwacho chimakhala ndi msinkhu wokulirapo
Chachiwiri-Kuchiritsa-Kuwala
1.SLA
Ntchito mfundo:
Stereolithography inali ukadaulo woyamba wopezeka pamalonda wa 3D.Imagwira ntchito polimbitsa chithunzithunzi chamadzimadzi mu gawo lomaliza potsata laser yamphamvu kwambiri pa mbale yomangirira yofanana ndi gawolo.Ntchitoyi ikupitirira pamene gawo lililonse lotsatila likuphatikizana ndi gawo lapitalo.Tekinoloje iyi imapanga magawo okhala ndi mawonekedwe olondola kwambiri.
Mawonekedwe:
Kuipa:
1. Zinthuzo zimakwiyitsa komanso ndi poizoni pang'ono
2. Zokwera mtengo
3. Mukasindikiza, yeretsani, chotsani bulaketi, ndi kuwala kwa UV kuti muchiritse kachiwiri.
2.LCD
Ntchito mfundo:
3D LCD printer ndi chosindikizira chomwe chimagwiritsa ntchito ukadaulo wosindikiza utomoni wochiritsa.Mosiyana ndi osindikiza achikhalidwe a 3D omwe amasindikiza wosanjikiza ndi wosanjikiza, osindikiza a LCD 3D amagwiritsa ntchito kuwala kwa UV kusindikiza zigawo zonse nthawi imodzi.Izi zikutanthauza kuti kusindikiza kwa 3D kokhala ndi chosindikizira cha 3D LCD kumathamanga komanso kumalondola kwambiri kuposa osindikiza ena a 3D.
Chomwe chimasiyanitsa osindikiza a LCD 3D ndi mitundu ina ya osindikiza a 3D, monga osindikiza a DLP kapena SLA, ndi gwero lawo lowala.Osindikiza a LCD 3D amagwiritsa ntchito magulu a UV LCD ngati magwero owunikira.Chifukwa chake, kuwala kochokera pagulu la LCD kumagunda malo ogwirira ntchito molunjika.Chifukwa kuwalaku sikukukulirakulira, kupotoza kwa pixel sikukhala vuto pakusindikiza kwa LCD.
Mawonekedwe:
Kuipa:
1. Chophimba cha LCD chili ndi moyo waufupi ndipo chiyenera kusinthidwa pambuyo pa kusindikiza kwa maola masauzande.
2. Zinthuzo zimakwiyitsa komanso ndi poizoni pang'ono.
Chachitatu-Ufa Fusion
SLS, SLM
Ntchito mfundo:
Kusankha laser sintering kumagwira ntchito poyika pulasitiki ya ufa ndikutsata gawolo ndi laser.Laser amasungunula ufa ndikuwusakaniza.Wosanjikiza wina wa ufa wa pulasitiki umayikidwa pamwamba pa wosanjikiza wapitawo, ndipo laser imasungunula mawonekedwe amtundu wapakatikati kwinaku akusakaniza mu gawo lapitalo.Ngati pali njira zotulutsira ufa wosasungunuka, ndondomekoyi imatha kupanga zigawo zolondola kwambiri zomwe zingathe kusindikizidwa m'malo mwake.
Mawonekedwe:
Kuipa:
1. Mtengo wake ndi wokwera mtengo kwambiri
2. Warping sachedwa kuchitika posindikiza zigawo zazikuluzikulu
3. Pamakhala fungo lalikulu pogwira ntchito
Chidule
Nkhaniyi ikufotokoza zaukadaulo wosindikiza wa 3D wosiyanasiyana ndi mawonekedwe malinga ndi mitundu ya kusindikiza kwa 3D.Kuti mudziwe zambiri za mitundu yosindikizira ya 3D komanso zambiri zokhuza kukhathamiritsa zinthu zanu zosindikizidwa za 3D,Lumikizanani nafe.
