Digital dentistry inovimba ne3D modhi mafaera kugadzira nekugadzira mazino ekudzoreredza senge korona, mabhiriji, anodyara, kana anogadzirisa. Iwo matatu anonyanya kufaera mafomati anoshandiswa STL, PLY, uye OBJ. Imwe neimwe fomati ine zvayakanakira nezvayakaipira pakushandisa mazino. Mune ino blog positi, ngationgororei mutsauko uripo pakati pemafomati matatu anozivikanwa efaira mudhijitari mazino.

 

1. STL (Standard Tessellation Mutauro)

STL inozivikanwa zvakanyanya seyakajairwa indasitiri fomati ye3D kudhinda uye CAD/CAM application, kusanganisira yedhijitari mazino. Inomiririra 3D nzvimbo semuunganidzwa wemativi matatu, inotsanangura geometry yechinhu.

Pros
Zviri nyore: Mafaira eSTL anongori nechepamusoro geometry data yechinhu che3D, chinomiririrwa semambure matatu. Iko hakuna mavara, maumbirwo, kana imwe data yekuwedzera. Uku kupusa kunoita kuti STL mafaera ave nyore kubata uye kugadzirisa.

Kugarisana: STL ndiyo inonyanya kugamuchirwa fomati mu3D kudhinda software uye hardware. Inenge yakavimbiswa kuti chero 3D printer kana CAD software ichakwanisa kubata STL mafaera.

Cons
Kushaya Ruzivo Rwemavara: Mafaira eSTL haasanganisi ruvara, magadzirirwo, kana imwe dhata yekuwedzera, achiganhurira mashandisiro aanoita mumaapplication anoda kuona kwechokwadi kana ruzivo rwakadzama, senge dzidzo yemurwere kana kushambadzira.
Metadata kuderedza: Iyo STL faira haigone kuchengetedza metadata, yakadai semunyori, copyright, uye nzvimbo, izvo zvakakosha pakushambadza.

2. PLY (Polygon File Format)

PLY fomati, yakatanga kugadziridzwa kuStanford University, inopa zvakawanda-siyana zvichienzaniswa neSTL. Iyo inogona kuchengeta kwete chete geometry asiwo yekuwedzera data hunhu seruvara, magadzirirwo, uye kunyange zvinhu zvenyama. Izvi zvinoita kuti mafaera ePLY ave akakodzera maapplication anoda yakasimbiswa inomiririra inomiririra, senge digital kunyemwerera dhizaini kana chaiyo yekuedza-ins. Nekudaro, zvakakosha kucherechedza kuti mafaera ePLY anowanzo kuve akakura muhukuru, izvo zvinogona kukanganisa kuchengetedza uye kuendesa data.

Pros

Zvakasiyana-siyana:PLY mafaera anogona kuchengeta kwete geometry chete asiwo yekuwedzera data hunhu seruvara, magadzirirwo, uye zvinhu zvemukati, zvichibvumira kukwidziridzwa kwekuona.
Detailed Data:PLY mafaera anogona kutora ruzivo rwakaoma senge tembiricha kana kudzvanywa, achiita kuti abatsire pakuongorora kwepamberi uye kutevedzera.

 

Cons

Kukura Kwefaira Yakakura:PLY mafaera anowanzo kuve akakura muhukuru nekuda kwekuiswa kweimwe data, iyo inogona kukanganisa kuchengetedza uye kunonoka nguva yekugadzirisa.

Kugarisana: PLY mafaera haawanzo kutsigirwa ne3D printers uye CAD software kana ichienzaniswa neSTL. Izvi zvingada mamwe matanho ekutendeuka asati agadziriswa.

3. OBJ (Object File Format)

OBJ imwe yakakurumbira faira fomati mudhijitari mazino, inozivikanwa nekushandiswa kwayo kwakapararira mu 3D modhi uye kupa maapplication. Mafaira eOBJ anogona kuchengeta ese ari maviri geometry uye mameseji data, achiaita akakodzera kune maapplication uko kwekuona kwechokwadi kwakakosha. Kuenderana kwayo nemapuratifomu akasiyana-siyana esoftware uye kugona kubata mamodhi akaomarara kunoita kuti OBJ ive sarudzo inosarudzika yekufananidza mazino epamberi uye kuronga kurapwa chaiko.

Pros
Ruzivo uye Rudzi Ruzivo: Kufanana nePLY, mafaira eOBJ anogona kuchengeta mameseji uye ruzivo rwemavara, achipa mamwe mamodheru akadzama.
Kugarisana: OBJ inotsigirwa zvakanyanya mukati me3D modelling software. Nekudaro, haasi ese maprinta e3D anotsigira mafaira eOBJ zvakananga.

Cons
Yakakura Faira Saizi: Mafaira eOBJ, kunyanya aya ane mepu yemepu, anogona kunge akakura, anogona kunonoka kugadzirisa nguva.
Kuoma kunzwisisa: Mafaira eOBJ anogona kuve akaomarara kushanda nawo kana achienzaniswa neSTL nekuda kwemamwe data maficha avanotsigira.

Kusarudza pakati peSTL, PLY, uye OBJ zvinoenderana nezvaunoda kubva kune yako 3D modhi. Kana kureruka uye kuenderana kwakakura kuri kiyi, STL inogona kunge iri sarudzo yakanyanya kunaka. Kana iwe uchida yakadzama ruvara kana imwe data, funga PLY kana OBJ. Senguva dzose, zvakakosha kuti utarise kugona uye zvipimo zveyako chaiyo software uye hardware.

 

Sarudzo yefaira fomati ingori nhanho imwe chete mukuita kwedhijitari mazino. Nekudaro, kunzwisisa aya mafomati uye nezvaanoreva zvinogona kukubatsira iwe kuita sarudzo dzine ruzivo uye pakupedzisira kupa zvirinani kutarisirwa kwemurwere uye kurapwa.
