I-STL Iifayile kunye ne-3D Printing
Ifomathi yefayile yefayile yefayile eqhelekileyo iyifayile ye .STL. Ifomathi yefayile ikholelwa ukuba yenziwe yi-3D Systems ukusuka kwi- ST ereo L ithographic software ye-CAD software kunye noomatshini.
Njengafomathi ezininzi zeefayile, zikho ezinye iinkcazo malunga nendlela le fayile efumana ngayo igama layo: I-Standard Tessellation, oku kuthetha ukuthambisa okanye ukubeka iifom zejometri kunye namaphetheni (ngaphezulu okanye ngaphantsi).
Yintoni iForm File File?
Inkcazo elula yokuyiqonda ifomati yefayile ye-STL ichaza njengento ebonakalayo yesigxina se-3D into.
Ukuba ukhangele umfanekiso, umdwebo we-CAD ukhombisa imigca epholileyo kwimibutane, apho umzobo we-STL ubonisa ubuso bendulungu njengoluhlu lwee-triangles ezixhunyiwe.
Njengokuba ubona kwisithombe / umzobo, iifayile ezipheleleyo ze-CAD zesangqa ziya kubonakala ngathi, kakuhle, isangqa, kodwa ingqungquthela ye-STL yayiza kufaka iqoqo, okanye i- mesh , ye-triangles ukugcwalisa eso sithuba kwaye ipapashwe yiyona Iiprinta ze-3D. Nesi sizathu sokuba uya kuva abantu bebhekisa okanye bachaze imifanekiso yeprinta yefayile njengamafayili e-mesh - kuba ayinamandla kodwa iyenziwe ngamathathu angqambela ukudala imitha okanye ukubukeka okunjenge-net.
Iiprinta ze-3D zisebenza ngeefayile ezifomathiweyo ze-STL. Iiphakheji ezininzi ze-3D, ezifana ne-AutoCAD, SolidWorks, Pro / Engineer (oku ngoku i-PTC Creo Parametric), phakathi kwabanye, unokudala ifayile ye-STL ngokukodwa okanye ngesixhobo sokongeza.
Sifanele sitsho ukuba kukho ezinye iifom zefayile eziprintiweyo ezinkulu ze-3D ngaphezu kwe .STL.
Ezi ziquka .OBJ, .AMF, .PLY, kunye noWRL. Kulabo abangekho mfuneko yokudweba okanye ukudala ifayile ye-STL, kukho ezininzi izibukeli ze-STL okanye abafundi abafumanekayo.
Ukudala ifayile ye-STL
Emva kokuyila umzekelo wakho kwinkqubo ye-CAD, unokhetho lokugcina ifayile njengefayile ye-STL. Ngokuxhomekeke kwiprogram kunye nomsebenzi owenzayo, unokwenza ucofe Gcina njengokuba ubone inketho yefayile ye-STL.
Kwakhona, ifomathi yefayile ye-STL yenza, okanye ukudala umzobo wakho womzobo kwisikiti se-triangles.
Xa usenza i-3D ukuskena into, kunye ne-scanner laser okanye esinye isicatshulwa se-digital imaging, ngokuqhelekileyo ubuyisela imodeli engummiselo kwaye awuyomelele, njengoko ungathanda ukuba udale idrafti ye-3D CAD.
Iiprogram ze-CAD zenza uninzi lwale nto elula kakhulu, ukwenza umsebenzi wokuguqula wena, nangona kunjalo, ezinye iinkqubo ze-3D zokumisela ziza kukunika ulawulo olukhulu phezu kwenani kunye nobungakanani be-triangles, umzekelo, onokukunika ubuninzi obuninzi okanye obunzima bomgca kwaye ngaloo ndlela i-3D ibhalwe ngcono. Ngaphandle kokungena kwiinkcukacha ezahlukeneyo ze-software ye-3D, unokutshintsha izinto ezininzi ukudala ifayile engcono ye-STL:
Ukunyamezela kweChordal / Ukuphambuka
Lo umda phakathi kobuso bomzobo wangaphambili kunye neeronate (ezikhethiweyo okanye ezikhonxweweyo).
Ulawulo lweNgqungquthela
Unokuba nezikhala phakathi kwama-triangles, kunye nokutshintsha ii-angles (ukuphambuka) phakathi kwama-triangles asondeleyo kuya kuphucula isisombululo sakho sokushicilela-esichazela ngokucacileyo ukuba unesilingo esingcono sezinto ezimbini zontathu. Esi silungiselelo sikwenza ukuba ukwandise ukuba izinto ezikufutshane zikhehliweyo okanye zihlanganiswe kunye (uvavanyo oluqhelekileyo).
Binary okanye ASCII
Iifayili zeBhanari zincinci kwaye kulula ukuyibelana, ukusuka kwi-imeyile okanye ukulayisha kunye nokukhuphela kwimiba. Iifayile ze-ASCII zinenzuzo yokuba lula ukuba ufunde ngokubonakalayo kwaye ukhangele.
Ukuba ufuna ukukhawuleza kwendlela yokwenza oku kwiinkqubo ezahlukeneyo ze-software, tyelela i-Stratasys Direct Manufacturing (owayekade u-RedEye): Indlela yokulungisa i-STL Ifayile ye-Files.
Yintoni eyenza 'iFil' ifayile ye-STL?
"Ngamafutshane, ifayile efanelekileyo ye-stl ifanele ihambisane nemigaqo emibini. Umgaqo wokuqala uthi ama-triangles asondeleyo kufuneka abe neentsimbi ezimbini ezifanayo. Okwesibini, ukuqhelaniswa kwezi-triangles (naluphi uhlangothi lwenxantathu, kwaye luphi na icala lucala) njengoko kuchazwe ngamagqabantshintshi kunye neziqhelo kufuneka zivumelane. Ukuba kukho enye yeendlela ezi-2 ezingagqibekanga, iingxaki zikhoyo kwifayile ye stl ...
Kwiinkqubo ezininzi ze-CAD, inani leenxantathu ezimelela imodeli linokuchazwa ngumsebenzisi. Ukuba i-triangles ezininzi zinokudalwa, ubukhulu befayile ye stl buya kuba bunzima Ukuba kukho izidalwa ezimbalwa zee-triangles, iindawo eziphihliweyo azichazwanga kakuhle kwaye i-cylinder iqala ukubonakala njenge-hexagon (jonga umzekelo apha ngezantsi).
