Digital Dentistry imadalira mafayilo amtundu wa 3D kupanga ndi kupanga zobwezeretsa mano monga akorona, milatho, implants, kapena zolumikizira.Mafayilo atatu omwe amagwiritsidwa ntchito kwambiri ndi STL, PLY, ndi OBJ.Mtundu uliwonse uli ndi zabwino ndi zoyipa zake pazogwiritsa ntchito mano.Mu positi iyi ya blog, tiyeni tifufuze za kusiyana kwa mafayilo atatu otchuka kwambiri muukadaulo wamano wa digito.

 

1. STL (Chiyankhulo Chokhazikika cha Tessellation)

STL imadziwika kwambiri ngati mtundu wamakampani osindikizira a 3D ndi mapulogalamu a CAD/CAM, kuphatikiza udokotala wamano wa digito.Imayimira mawonekedwe a 3D monga gulu la magawo atatu, kutanthauzira geometry ya chinthucho.

Ubwino
Kuphweka: Mafayilo a STL ali ndi data ya geometry ya chinthu cha 3D chokha, chomwe chimaimiridwa ngati mauna atatu.Palibe mitundu, mawonekedwe, kapena zina zowonjezera.Kuphweka kumeneku kumapangitsa mafayilo a STL kukhala osavuta kunyamula ndi kukonza.

Kugwirizana: STL ndiye mtundu wovomerezeka kwambiri pamapulogalamu onse osindikizira a 3D ndi zida.Ndi pafupifupi kutsimikiziridwa kuti chosindikizira aliyense 3D kapena CAD mapulogalamu athe kusamalira STL owona.

kuipa
Kupanda Chidziwitso cha Mitundu: Mafayilo a STL samaphatikizapo mtundu, mawonekedwe, kapena zina zowonjezera, kuletsa kugwiritsa ntchito kwawo pamapulogalamu omwe amafunikira zenizeni kapena zambiri, monga maphunziro a odwala kapena kutsatsa.
Kuchepetsa kwa metadata: Fayilo ya STL siyingasunge metadata, monga wolemba, kukopera, ndi malo, zomwe ndizofunikira pakusindikiza.

2. PLY (Polygon File Format)

Mtundu wa PLY, womwe udapangidwa ku Yunivesite ya Stanford, umapereka mwayi wosiyanasiyana poyerekeza ndi STL.Ikhoza kusunga osati geometry yokha komanso zina zowonjezera deta monga mtundu, maonekedwe, ngakhale katundu.Izi zimapangitsa kuti mafayilo a PLY akhale oyenera kugwiritsa ntchito mapulogalamu omwe amafunikira mawonekedwe owoneka bwino, monga kapangidwe ka kumwetulira kwa digito kapena zoyeserera.Komabe, ndikofunikira kudziwa kuti mafayilo a PLY amakhala okulirapo, zomwe zingakhudze kusungidwa ndi kusamutsa deta.

Ubwino

Kusinthasintha:Mafayilo a PLY sangasunge ma geometry okha komanso mawonekedwe owonjezera a data monga mtundu, mawonekedwe, ndi zinthu zakuthupi, zomwe zimalola chiwonetsero chowoneka bwino.
Zambiri:Mafayilo a PLY amatha kujambula zidziwitso zovuta monga kutentha kapena kukakamiza, zomwe zimapangitsa kuti zikhale zothandiza pakuwunika kwapamwamba komanso kuyerekezera.

 

kuipa

Kukula Kwa Fayilo Yaikulu:Mafayilo a PLY amakhala okulirapo chifukwa chophatikizira deta yowonjezera, yomwe ingakhudze kusungirako ndikuchepetsa nthawi yokonza.

Kugwirizana: Mafayilo a PLY sathandizidwa kawirikawiri ndi osindikiza a 3D ndi mapulogalamu a CAD poyerekeza ndi STL.Izi zingafunike njira zina zosinthira musanakonze.

3. OBJ (Fomati ya Fayilo Yachinthu)

OBJ ndi mtundu winanso wodziwika wamafayilo wamano a digito, omwe amadziwika kuti amagwiritsidwa ntchito kwambiri pakupanga ma 3D ndikupangira mapulogalamu.Mafayilo a OBJ amatha kusunga zonse za geometry ndi kapangidwe kake, kuwapanga kukhala oyenera kugwiritsa ntchito komwe kuwonetsetsa ndikofunikira.Kugwirizana kwake ndi mapulatifomu osiyanasiyana apulogalamu komanso kuthekera kogwiritsa ntchito mitundu yovuta kumapangitsa OBJ kukhala chisankho chokondedwa pamayesero apamwamba a mano ndikukonzekera chithandizo chamankhwala.

Ubwino
Chidziwitso cha Maonekedwe & Mtundu: Monga PLY, mafayilo a OBJ amatha kusunga mawonekedwe ndi mitundu, ndikupereka zitsanzo zatsatanetsatane.
Kugwirizana: OBJ imathandizidwa kwambiri pamapulogalamu onse opanga ma 3D.Komabe, si onse osindikiza a 3D omwe amathandiza mafayilo a OBJ mwachindunji.

kuipa
Kukula Kwakukulu Kwa Fayilo: Mafayilo a OBJ, makamaka omwe ali ndi mamapu amtundu, amatha kukhala akulu kwambiri, omwe amatha kuchepetsa nthawi yokonza.
Kuvuta: Mafayilo a OBJ amatha kukhala ovuta kwambiri kugwira nawo ntchito poyerekeza ndi STL chifukwa chazinthu zowonjezera zomwe amathandizira.

 

 (Fayilo ya OBJ idatumizidwa kuchokera kuLaunca DL-300P)

Kusankha pakati pa STL, PLY, ndi OBJ zimatengera zomwe mukufuna kuchokera ku mtundu wanu wa 3D.Ngati kuphweka komanso kuyanjana kwakukulu ndikofunikira, STL ikhoza kukhala chisankho chabwino kwambiri.Ngati mukufuna mtundu watsatanetsatane kapena zambiri, lingalirani za PLY kapena OBJ.Monga mwanthawi zonse, ndikofunikira kulingalira za kuthekera ndi malire a pulogalamu yanu ndi hardware.

 

Kusankha wapamwamba mtundu ndi sitepe imodzi yokha mu ndondomeko ya digito mano.Komabe, kumvetsetsa mawonekedwe awa ndi tanthauzo lake kungakuthandizeni kupanga zisankho zodziwika bwino ndipo pamapeto pake mudzapereka chisamaliro chabwino cha odwala komanso chithandizo chamankhwala.
