Lo mdwebo weemathematika ozipholileyo ungenza imodeli epholileyo kakhulu ye-3D
Xa ufumana ukunyathelisa kwi-3D, ubuyela esikolweni, ukuze uthethe. Omnye uthumela i-3D imodeli, kodwa idinga utshintsho okanye ukupholisa kwaye uvula isofthiwe ye-3D yoyilo.
Uva abantu bethetha malunga neengxantathu ezixhumeneyo, malunga nemodeli yeemitha, malunga neenjini ze-NURBS, kunye nokwenza imodeli "emanzini" phambi kokuzama ukuyiprinta. Yonke into yokuzonwabisa okanye indlela ebomini ithatha ixesha lokufunda izinto ezisisiseko kunye nezintlu.
Emva koko ubona umntu wenza into ebonakalayo yokudala nge-3D model ngokuyijika ibe yi-Voronoi Pattern. Huh?
Ndifumene le ngqungquthela encinane eThitsverse kwaye yangikhumbuza inja kwi-Up !, ifilimu ehambelayo, ngoko ndayilanda ukuba iphrinta. Njengoko ubona, kunesakhiwo esingaqhelekanga - ezo zimbobo ze-swiss ziyaziwa njenge-Voronoi Patterns. Umfanekiso ndiwubonisayo uvela kwinkqubo ye-Cura slicer, kodwa i-Squirrel Voronoi-Style yasekuqaleni i-Thingiverse, ngu-Hegglin waseRoma, ngoko unokuzikhuphela ngokwakho. UmRoma ungumqambi osebenzayo kwaye unemizekelo emininzi ye-3D ayabelana ngayo nabanye. Ndiyonwabela umsebenzi wakhe.
Emva kokushicilela i-3D i-squirrel, kwi-LulzBot Mini ethembekileyo (i-unit loaner unit), ndagqiba kwelokuba ndikhange ndifune okungakumbi malunga nale mibono. Njengabaninzi abanomdla wokunyathelisa i-3D, ndandilandela umzekelo ovela eThitsverse ngaphandle kokucinga ngendlela endiyenza ngayo ngokwam. Kwaye, ngokwemvelo, ndagijima kum buddy wam, uMarshall Peck, ukusuka ku-ProtoBuilds, oya kubafundi abaza kukhumbula ngumntu owabelana ngendlela yokwakha i-Printer yakho yokuqala ye-3D ye-3D.
UMarshall uchaza itoni kwiblogi yakhe kunye nakwi-Instructables, epheleleyo kunye neesikrini, ngoko uya kufuna ukuhamba apho ukuze uyihlole: Indlela yokwenza i-Voronoi Patterns nge-Autodesk® Meshmixer.
Ezi ipateni zinokubonelela ngeziqendu ezihambayo ezingqameneyo zetekisi ezinokuba luncedo xa usebenzisa i-SLA / i-resin 3D printers.
Iimpawu ze-Voronoi zingashicilela kakuhle kwiiprinta ezininzi zeFused Filament 3D. Njengoko ndithethile, ndazama kwiLulzBot Mini.
Ekuhambeni kwam kuqala, ngokungabi nasiphoso somshicileli, ndishiye nge-squirrel esisiqingatha. Ngesibili hamba, ndivumela uCura ukuba awamkele inkxaso, eyayiyinto enhle neyingozi. Isebenzisa itoni yezinto eziphathekayo kwaye kufuneka uyiqhekeza, yinqumle, uyitshathise yonke into yokushicilela yakho yokugqibela ye-3D. Ngokuqinisekileyo ndidala isithuba kwi "Tips for Removing 3D Print Support Structures."
Inyathelo 1: Ukungenisa iModeli kunye nokunciphisa iipolgoni
1) Ngenisa imodeli kwi-Meshmixer [Ngenisa icon] okanye [ifayile]> [Ngenisa]
2) Khetha imodeli yonke usebenzisa ikhibhodi Ctrl + okanye sebenzisa [khetha] ithuluzi ukunqakraza-ukuhambisa ezinye iindawo ofuna ukuzihlela.
3) Cofa [Hlela]> [Nciphisa] (Imenyu ibonakala phezulu emva kokukhetha).
4) Ukwandisa ipesenteji okanye ukutshintsha ukuhla ukuya kunxantathu ephantsi / isibalo se-polygon. Iipolandoni ezingaphantsi ziphumela kwizivulo ezinkulu kumzekelo wakho wokugqibela. Inokukunceda ukuzama inani elincinane kakhulu le-polygon.
5) nqakraza [yamkela].
Inyathelo 2: Faka isicelo kwaye uguqule i-Pattern
1) Cofa [Hlela] icon yemenyu> [Yenza Iphetheni]
2) Shintsha ukuhla kweyokuqala ukuya kwi [Iingqimba ezimbini] (iphethini usebenzisa ngaphandle kuphela) okanye [I-Mesh + Delaunay] I-Edges Edges (ivelisa iphethini ngaphakathi ngaphakathi). Ukutshintsha [ubukhulu bezinto] kuya kwenza iibhubhu ezinqamle okanye ezincinci.
3) Ukugcina imodeli: Ifayile> ukuthumela ngaphandle .STL* Ukulungiswa kwezicwangciso ezithile zepatheni kungadinga ukusebenzisa i-CPU enzulu.
* Emva kokuchofoza ukwamkela, unokufuna ukunciphisa iipolgoni ezintsha ezintsha ze-3D ukuprinta okanye ukungenisa kwezinye iiprogram.
Ndixelele ukuba uprinta nayiphi na imizekelo ye-Voronoi Pattern. Ndingathanda ukuva malunga nalo. Cofa iqhagamshelo le-TJ McCue bio apha okanye ngaphezulu ngasemva kwesithombe sam.
