Kufamba zvakadzika neEvenEngine scanner nyanzvi Dan Gustafson
Paunenge uchigadzira chinhu cheD 3D uchishandisa purogiramu yeCAD, mapurogiramu anozivikanwa zvikuru anoshandisa "polygon mesh" kana " N on- U chimiro R B B asis S pline" (NURBS) kutsanangura chinhu.
Panzira yekuumba faira yekudhinda 3D, mapurogiramu akawanda eCAD anokubvumira kuti uchinje faira ku STL mafaira (iyo iri kuitenderera kuva katatu yema polygon mesh), kuitira kuti iwe unganetseka kana iwe uchifanira kugadzira chinhu ne mesh kubva kutanga kana kana zviri nani kushanda muNURBS uye woita kutendeuka.
Isu takabvunzurudza Dan Gustafson kubva kuneEllEngine , kambani inotungamirira 3D scanner, kuti tione nharo dzakanakisisa dzemhando mbiri idzi dze 3D mhando.
Sezvo kusvika pamakombiyuta ekuenzanisira kuenda, NURBS ichaita mifananidzo yakaoma. Ichagadzirisawo mhando dzakanyatsorongeka nemitemo isina kuiswa pasi. Nekugadzirwa kwemainjiniya nemagetsi, NURBS-based kombiyuta inoshandurwa inoshandiswa ku polygon mesh yakarongwa nemapurogiramu. Kazhinji, paunotarisa zvinhu muchirongwa cheCAD, ivo vanotanga kuverengwa vachishandisa NURB
Paunenge uchishanda muNURBS, uri kuenzanisa rutivi pakati pepakati. Iko hunoti huchaita meshani yakakosana pamusoro pemakona. Kuti uchinje maruva, unofanirwa kuchinja pfungwa pamhete. Izvi zvingava zvishoma zvakaoma kutaura.
NURBS ine zvisingakwanisi. Nokuti iri fomu yekupa 2-dimensional, unofanirwa kuumba "zvipfeko" zvaunobatanidza pamwe chete kuitira kuti uite zvakaoma 3-dimensional shape. Mune zvimwe zviitiko, mavara aya haakodzeri pamwe chete uye "kumira" kunooneka. Zvakakosha kutarisisa zvakananga pane chimwe chinhu paunenge uchigadzirisa uye unoita kuti zvikwata zvienderane zvakakwana usati wazvishandura kuva mesh yeFLL faira.
Pigononi mesh yakasikwa kunyanya kupa zvinhu 3-dimensional pamakombiyuta. Nemhaka yeizvi, iyo inomiridziro inoshandiswa neFSL mafaira. Paunoshandisa zvitatu kuti uumbe maumbirwo eD 3D, unoita zviyero zve-smooth edges. Iwe hauzombofi wakagadzirisa zvakakwana kufanana kwechifananidzo chekutanga chakagadzirwa muNURBS, asi mesh iri nyore kutevedzera. Iwe unokwanisa kusundira nekukwevera pamatare kuti uende nayo uye uwane mhinduro imwe chete nguva imwe neimwe nokuti haisi kuverenga masvomhu mapeji emapu.
Apo iwe unoshanda muNURBS uye unoshandura faira iwe mumashini, unogona kusarudza sarudzo yako. Pfungwa yakakwirira inokupa magetsi anotsvaga mune chimwe chinhu chauri kudhinda. Zvisinei, kukwirira kwakakwirira kunoreva iwe uchava nefaira huru. Mune zvimwe zviitiko, faira yacho inogona kuva yakakura kwazvo kuti 3D printer ishande.
Kunze kwekuwana kuenzanisa kwakakwana pakati pekugadzirisa uye kufara kwefaira, unogona kushandisa dzimwe nzira dzokuchenesa kuderedza faira yako yefaira. Semuenzaniso, unofanirwa kuve nechokwadi kuti pawakagadzira chinhu chausina kuumba nzvimbo dzomukati dzisingagoni kudhindwa. Imwe nzira iyo izvi zvinogona kuitika ndeyekuti iwe unobatanidza maumbirwo maviri pamwe chete, dzimwe nguva kubatana kunobatana kunotsanangurwa, kunyange zvazvo, kana vakadhinda, havazovi nzvimbo dzakasiyana.
Pasinei nokuti iwe pakutanga unoshandisa chinhu chako kushandisa NURBS kana mesh inobva pane zvaunoda. Kana iwe uchida purogiramu iri nyore iwe yausingazofaniri kutendeuka, kutangira meshini ichava yakanakisisa sarudzo. Kune rumwe rutivi, kana iwe uchida purogiramu inokupa mazai akakwana, unofanira kusarudza imwe inoshandisa NURBS (Rhino muenzaniso mumwe chete unoti, chaizvoizvo, iwo ane muongorori mukuru: Ndezvipi NURBS?).
Ini ndichavhara iyi chinyorwa neyi: Hurongwa hweD 3D Design iwe unonyatsonakidzwa nawo, zvichida, uchava nechisarudzo chekutumira yako NURBS kana Mesh file kune STL kana mamwe mafaira ekudhinda 3D. Pakupedzisira, tinoteerera mazano aSherri Johnson, kubva kuCatzPaw, watakabvunzurudza mazano uye maitiro: Kugadzira 3D Files ne Meshmixer uye Netfabb .
"Dhigirii yeStL inoda kuzarurirwa mune purogiramu yevashandi inogona kuongorora nyaya uye kugadzirisa nyaya idzodzo, zvichida kana kuti zvinyorwa. Mamwe mapurogiramu ekucheka (akadai seChislify3D) anopa mashandisi ekugadzirisa sezvinoita mamwe mapurogiramu eCAD (SketchUp extensions). Maitiro akazvitsaurira ayowo akasununguka, uye anosanganisira zvinhu zvakanyanya kugadzirisa ndeye Netfabb uye MeshMixer . "
Zvimwe zvinhu zvakawanda zvekunzwisisa maitiro akasiyana-siyana anobva ku 3D 3D service service bure (apo tinotaura nezvaCulpteo uye Shapeways, kunongedza varume vaviri chete). Aya makambani anofanirwa kutora mafaira emafuta uye maitiro kubva munharaunda yose ye 3D design design panyika uye kazhinji ane mazano makuru uye mazano ekutora mafaira ako kudhinda zvakakodzera.
Heino imwe kubva kuSculpteo inopa dzidzo pakushandisa Rhino 3D, kunyanya. Iwe unogonawo kudzidza nezvekushandisa Meshmixer kana Autodesk Inventor kana Catia kana Blender mune chikamu ichi cheSculpteo: 3D Printing Tutorials: Gadzirai muenzaniso wekudhinda 3D .
Nemhaka yekuti vazhinji vanofambisa uye makombiyuta emagetsi anowanikwa ku 3D kudhindwa nehutano hwekusika vanhu, Shapeways inopa imwe iyo yakanyatsokodzera mubhadharo: Ungagadzirira sei Render / Animation Model ye 3D Printing.
Stratasys Direct Manufacturing (yaimbova RedEye) ine huru pane Yokugadzirisa Dhigirii yeStl iyo yatinosangana pedyo nekuguma kweStrl Files review.
