Ama-STL Amafayela nokuphrinta kwe-3D
Ifomethi yefayela ye- 3D yephrinta evamile kakhulu ifayela le-.STL. Ifomethi yefayili ikholelwa ukuthi idalwe yi-3D Systems kusuka kwisofthiwe ye- ST ereo L yohwebo lwe-CAD nemishini.
Njengamafomethi amaningi wefayela, kunezinye izincazelo zendlela lolu hlobo lwefayela oluthola ngayo igama layo: Standard Tessellation, okusho ukuhlanganisa noma ukubeka ubujamo bejometri namaphetheni (ngaphezulu noma ngaphansi).
Iyini ifomethi yefayela le-STL?
Incazelo elula yokuyiqonda ifomethi yefayili ye-STL ichaza njengokumelwa kwe-triangular kwe-3D into.
Uma ubheka isithombe, umdwebo we-CAD ubonisa imigqa ebushelelekile yemibuthano, lapho umdwebo we-STL ubonisa ubuso bombuthano njengochungechunge lwezinxantathu ezixhunyiwe.
Njengoba ungabona esithombeni / umdwebo, ifayela eliphelele le-CAD lombuthano lizobukeka sengathi, kahle, umbuthano, kepha inguqulo ye-STL ingabe ifaka iqoqo, noma imicu , yezintathu zokugcwalisa leso sikhala bese yenza ukuba iphrintiwe yiziningi Amaphrinta e-3D. Yingakho uzozwa abantu bebhekisele noma bahlathulule imidwebo ye-3D yephrinta njengamafayili ama-mesh - ngoba ayikho eqinile kodwa akhiwe ngamathantathu akhiqiza ukubonakala noma ukubonakala okunjenge-nets.
Amaphrinta e-3D asebenza ngamafayela afomethiwe we-STL. Amaphakheji amaningi we-3D, njenge-AutoCAD, SolidWorks, Pro / Engineer (okuyi-PTC Creo Parametric) manje, phakathi kwabanye, angakha ifayela le-STL ngokuzenzekelayo noma ngethuluzi lokungezelela.
Kufanele sikhulume ukuthi kunamanye amafomethi amafayela amakhulu okushicilela ama-3D ngaphezu kwe-.STL.
Lezi zihlanganisa .OBJ, .AMF, .PLY, no-.RL. Kulabo abangadingi ukudweba noma ukudala ifayela le-STL, kunabantu abaningi ababukeli be-STL noma abafundi abatholakalayo.
Ukwakha ifayela le-STL
Ngemuva kokuklama imodeli yakho ohlelweni lwe-CAD, unenketho yokugcina ifayela njengefayela le-STL. Kuye ngohlelo nomsebenzi owenzayo, kungadingeka uchofoze Londoloza Njengokubona inketho yefayela le-STL.
Futhi, ifomethi yefayili ye-STL ihlinzeka, noma idala ubuso bomdwebo wakho emathini wezintathu.
Uma wenza i-3D scan yezinto, nge-scanner laser noma enye idivaysi ye-imaging yediskithophu, uvame ukubuyisa imodeli yemifino hhayi eyomeleleyo, njengoba ubungathanda uma ngabe wadala umdwebo we-3D CAD odwetshiwe.
Izinhlelo ze-CAD zenza lokhu kube lula kakhulu, okwenza umsebenzi wokuguqulwa kwakho, noma kunjalo, ezinye izinhlelo ze-3D zokufanisa izokunika amandla okulawula ngaphezulu kwenani nosayizi we-triangles, isibonelo, okungakunikeza ubuso obuningi noma obunzima obukhulu futhi ngaleyo ndlela kungcono ukuphrinta kwe-3D okungcono. Ngaphandle kokungena kwizinto ezihlukahlukene ze-software ye-3D, ungashintsha izici eziningana ukuze udale ifayela elihamba phambili le-STL:
Ukubekezelelana kwe-Chordal / Ukuphambuka
Lona ibanga eliphakathi komdwebo wokuqala kanye nezintathu ezintathu ezisetshenzisiwe (ezicwebeziwe noma ezikhonjiwe).
Ukulawula i-Angle
Ungaba nezikhala phakathi kwama-triangles, nokushintsha ama-angles (ukuphambuka) phakathi kwama-triangles aseduze kuzokwenza ngcono ukulungiswa kwakho kokuphrinta-okusho ngokucacile ukuthi une-weld engcono yezingxenyana ezimbili zontathu. Lesi silungiselelo sikwenza ukwandise ukuthi izinto eziseduze zikhahlelwe kanjani noma zihlanganiswe ndawonye (tessellation ejwayelekile).
Binary noma ASCII
Amafayela kanambambili amancane futhi kulula ukwabelana, kusukela ku-imeyili noma ukulayisha nokulanda umbono. Amafayela we-ASCII anenzuzo yokuba lula ukubuka nokuhlola.
Uma ufuna i-rundown esheshayo yokwenza lokhu kwi-software ehlukahlukene, vakashela i-Stratasys Direct Manufacturing (eyayisanda ku-RedEye): Indlela Yokulungisa i-STL Amafayela we-Files.
Yini eyenza 'ifayela elibi' le-STL?
"Ngamafuphi, ifayela elihle le-stl kufanele lihambisane nemithetho emibili. Umthetho wokuqala uthi izinxantathu eziseduze kumele zibe namazwi amabili ajwayelekile. Okwesibili, ukuma kwezintathuli (ngakuphi uhlangothi lwenxantathu ongaphakathi nalokho okushiwo yilokho ohlangothini olukhona) njengoba kukhonjiswe ama-vertic and normals kufanele kuvumelane. Uma enye yalezi zindlela ezimbili zingagcwaliseki, izinkinga zikhona kwifayela le-stl ...
"Ngokuvamile amafayela we-stl angabizwa ngokuthi" kubi "ngenxa yezinkinga zokuhumusha. Ezinkambisweni eziningi ze-CAD, inani le-triangles elimelela imodeli lingachazwa ngumsebenzisi. Uma kunezinxantathu eziningi kakhulu ezidalwe, usayizi wefayela we-stl ungaba mnandi Uma kubalwa ama-triangles ambalwa kakhulu, izindawo ezigobile azichazwanga kahle futhi isilinda siqala ukubheka iheksagoni (bheka isibonelo esingezansi).
