Piv nrog rau feem ntau lwm yam kev tsim khoom, 3D luam ntawv yuav tsum tswj xyuas qhov tseeb ntawm ob lub qauv ntawm ib feem: cov phab ntsa sab nrauv thiab qhov txhaws. Sab nrauv phab ntsa, hais txog thaj tsam sab nraud ntawm ib feem, thaum lub muab tub lim yog dab tsi tshwm sim hauv qhov. Feem ntau, lub tshuab luam ntawv yuav muaj qee theem ntawm kev tswj hwm cov txiaj ntsig txawv teb chaws, tab sis qhov infill yog ntau zog thiab ua lub luag haujlwm loj hauv lub zog, qhov hnyav, qauv, buoyancy, thiab lwm yam. Hauv 3D luam ntawv, tus neeg siv tuaj yeem txhais tau ntau yam kev txwv los tswj hom infill siv rau ib feem.
Ntawm tag nrho cov tsis muaj, ob yog qhov tseem ceeb tshaj plaws: infill ntom thiab infill qauv. Hauv qab no, kuv yuav taug kev koj los ntawm "infill" los ntawm ob peb txoj kev tsim khoom sib txawv kom nkag siab zoo dua li cas nws ua haujlwm hauv 3D luam ntawv.
3D printing thiab tsoos manufacturing
Infill 3D luam ntawv txawv ntawm lwm yam, ntau txoj kev tsim khoom. Wb coj kev txhaj tshuaj molding thiab rho tawm kev tsim khoom ua piv txwv. Kev txhaj tshuaj molding yuav tsum tau muab cov khoom tso rau hauv pwm los ua ib feem, thiab vim yog qhov zoo ntawm cov thev naus laus zis, kev tswj cov qauv sab hauv tsuas yog ua tsis tau. Yog li ntawd, txhaj tshuaj molded qhov chaw yog cov khoom los yog hollow (nrog rau kev txhaj tshuaj molding), tsis muaj dab tsi nyob nruab nrab ntawm. Subtractive manufacturing, zoo li CNC machining, yuav tsum tau txiav cov khoom. Zoo ib yam li kev txhaj tshuaj molding, lub filling tsis tuaj yeem hloov kho, yog li cov khoom sab hauv yog tag nrho. Tab sis 3D luam ntawv tuaj yeem tsim txhua qhov loj thiab ua rau nws txheej txheej los ntawm cov khoom siv extruding.
Fill qhov ntom tuaj yeem cuam tshuam cov khoom siv
Fill density yog "fullness" nyob rau hauv ib feem. Nyob rau hauv lub slicer, nws yog qhia raws li ib feem pua ntawm {{0}} feem pua mus rau 100 feem pua, qhov twg 0 feem pua txhais tau tias ib nrab hollow thiab 100 feem pua txhais tau tias tag nrho. Fill ceev tuaj yeem cuam tshuam qhov hnyav ntawm ib feem: qhov puv sab hauv ntawm ib feem, qhov hnyav dua nws yuav yog. Dhau li ntawm qhov hnyav, lub sij hawm luam tawm, cov khoom siv, thiab buoyancy kuj raug cuam tshuam los ntawm infill ntom. Tib yam muaj tseeb rau lub zog, txawm hais tias tau kawg nws kuj muaj feem xyuam rau ntau lwm yam xws li cov khoom siv thiab qhov siab hauv pem teb.
Qee cov hlais kuj tso cai rau qhov sib txawv ntawm qhov sib txawv hauv tib qhov. Qhov no yog hu ua variable infill density, thiab ib qho kev teeb tsa tshwj xeeb hauv cov txheej txheem slicing tso cai rau tus neeg siv los qhia meej txog qhov sib txawv ntawm qhov xav tau rau ntau qhov chaw ntawm cov ntawv luam tawm. Yog li, pes tsawg feem pua ntawm infill ntom yuav tsum tau siv hauv kev luam ntawv tiag tiag?
●15-50 feem pua ntawm qhov ntom ntom yog pom zoo rau feem ntau "tus qauv" luam tawm uas tsis tas yuav muaj zog ntxiv. Qhov feem pua ntawm qhov ntom ntom no txo cov sij hawm luam tawm, txuag cov khoom, thiab muab lub zog zoo.
●Functional prints yuav tsum muaj zog. Yog li, qhov kev sau ntau dua yog pom zoo: ntau dua 50 feem pua. Qhov kev teeb tsa no siv sijhawm ntev dua los luam tawm thiab siv cov filament ntau dua tab sis ua rau muaj zog dua.
●Rau cov qauv duab uas siv rau cov hom phiaj tso saib nkaus xwb, 0-15 feem pua ntawm qhov ntom ntom tau pom zoo. Qhov no ua rau kom ceev luam ntawv thiab tsis haus ntau ntawm filament txhua. Cov qauv luam tawm hauv qhov ntom ntom no yuav yog lub teeb heev, tab sis tsis muaj zog heev.

Sau tus qauv
Cov qauv hatch yog cov qauv thiab cov duab ntawm cov khoom hauv ib feem. Los ntawm cov kab yooj yim mus rau ntau qhov geometries, cov qauv hatch tuaj yeem cuam tshuam rau ib feem ntawm lub zog, qhov hnyav, lub sijhawm luam tawm, thiab txawm tias yooj yim. Hauv cov kev pab cuam sib txawv, muaj ntau hom kev sau sib txawv.
Zoo li infill ntom, cov qauv infill sib txawv muaj cov khoom sib txawv xws li kev nyuaj, cov khoom siv tau zoo, thiab cov xov tooj ntawm cov dav hlau sib txuas (2D lossis 3D). Piv txwv li, ib tug kauv qauv txuas rau sab nrauv phab ntsa hauv peb qhov loj me, muab lub zog tag nrho. Yog li ntawd, tus qauv no siv cov khoom siv ntau dua li cov qauv xws li kab. Yog li twg tus qauv sau koj yuav tsum xaiv?
● Kab: Ib kab sau cov qauv muaj cov kab luam tawm hauv ib qho kev taw qhia (raws li X lossis Y axis) hauv txhua lwm txheej. Cov qauv infill no muab lub zog nyob rau hauv tsuas yog ob qhov ntev, uas yog qhov zoo rau kev luam ntawv ceev. Cov qauv kab tsis siv ntau yam khoom thiab hnyav hnyav.
●Honeycomb: Raws li lub npe qhia, tus qauv no tsim cov qauv honeycomb, tsim kom muaj qhov pom kev zoo nkauj. Cov qauv infill no haum rau cov ntawv luam tawm ib nrab ceev uas xav tau lub zog nruab nrab thiab tsis txhob haus cov khoom siv ntau dhau.
Daim phiaj: Ib daim phiaj sau cov qauv zoo ib yam li cov kab, tab sis tsis yog cov kab unidirectional txhua txheej, txhua txheej muaj ob-seem kab nrog ob npaug ntawm qhov chaw ntawm cov kab. Hom no muab ob-seem lub zog tab sis tseem muaj zog me ntsis. Daim phiaj qauv siv qhov nruab nrab ntawm cov khoom siv thiab siv sijhawm nruab nrab ntawm lub sijhawm ua kom tiav.
● Daim duab peb sab: Daim duab peb sab zoo li cov kab sib tshooj sib tshooj uas txuas mus rau peb txoj hauv kev hauv XY dav hlau. Cov qauv sau no tsuas yog muab lub zog hauv ob qhov ntev tab sis tseem tsim nyog rau cov ntawv luam tawm uas xav tau lub zog.
● Peb-txoj kev hexagon: Ib qho peb-hexagon sau qauv muaj ntau cov kab txuas ntxiv hauv peb txoj kev hauv XY dav hlau, tsim cov qauv hexagonal nrog daim duab peb sab hauv nruab nrab. Cov qauv sau no muab ob-seem lub zog, zoo meej rau kev luam ntawv hnyav.
●Cubes: Hom no tsim cov kab sib dhos, tab sis vim tias lawv tig 45 degrees nyob ib ncig ntawm X thiab Y axes, lawv zoo li daim duab peb sab txhua lub sijhawm. Cov qauv no muab lub zog zoo hauv peb qhov ntev tab sis xav tau cov khoom siv thiab sijhawm ntau dua li lwm cov qauv.
● Octet: Ib qho octet sau qauv zoo ib yam li lub voos xwmfab qauv, tab sis es tsis txhob ntxiv cov duab peb sab, cov qauv yog materialized li square. Cov qauv sau no yog cov qauv peb-dimensional uas tsis tsuas yog zoo nkaus li zoo tab sis kuj tseem muaj txiaj ntsig zoo rau cov khoom uas xav tau lub zog.
●Spiral: Kauv ntim cov qauv yuav zoo li qhov txias tshaj plaws, tab sis lawv kuj yog qhov txawv tshaj plaws ntawm cov qauv sau. Nws muaj ib tug concave irregular curvature uas xaus rau traversing txoj kev. Nws yog tsim los kom ua tiav qhov zoo tshaj plaws sib npaug ntawm lub zog, cov khoom siv, thiab lub sijhawm luam ntawv.
●Concentric: Ib qho concentric hatch qauv yog ib qho qauv tsim los ntawm concentric kab uas phim cov qauv ntawm ib feem (piv txwv li nws perimeter). Cov qauv no tuaj yeem luam tawm sai sai, haum rau qhov hloov pauv tau yooj yim, thiab siv cov khoom siv tsawg dua li cov qauv feem ntau.

Cov ntsiab lus
Ntxiv nrog rau cov qauv thiab qhov ntom ntom, muaj ob qhov tseem ceeb ntawm cov chaw sau: cov chaw sib txawv thiab cov qauv kos duab. Ob leeg tso cai rau koj kom muaj tswv yim ntau dua nrog cov chaw sau. Kuj tsis paub meej cov chaw pab kom koj hloov kho infill ntom ua ib feem prev zuj zus los ntawm txheej. Piv txwv li, yog tias koj xav kom hauv qab ntawm ib feem kom muaj 10 feem pua infill mus rau txheej 30, ces hloov mus rau 50 feem pua infill, qhov hloov pauv tau tso cai rau koj ua qhov no. Dab tsi tuaj yeem paub tau hauv software xws li Simplify3D, PrusaSlicer, thiab Cura? Infill rau kos duab yog ib txoj hauv kev los tig cov qauv sib txawv rau hauv cov duab kos duab. Cov txheej txheem no zoo nkaus li zoo rau qhwv ntsej, pendants, thiab lwm yam hniav nyiaj hniav kub thiab artwork.
