Cov tswv yim thiab cov tswv yim rau kev tshem cov khoom txhawb los ntawm koj cov ntawv luam tawm 3D
Leaning dhau yuav ua rau koj poob. Zoo nkauj cuab kev cai ntawm physics, tab sis thaum koj pib ua hauj lwm nrog 3D tshuab luam ntawv, koj yeej tsis xav txog nws. Txog thaum koj sim luam tawm ib yam dab tsi uas muaj ib qho kev sib tshuam los yog ib qho tshuaj tiv thaiv, hais ib txhais caj npab los yog lub tsho ntawm ib lub kaus mom loj loj, los yog tej zaum ib qho kev ncua deb ntawm ob lub ntsiab lus. Tom qab ntawd koj rov qab kawm txog cov cai ntawm physics thiab gravity.
3D printing yuav xav tau dab tsi yog hu ua kev them nyiaj yug. Ib yam khoom uas muaj ib qho tsis txaus siab lossis lwm yam tshaj li daim ntawv sau ua haujlwm (xav cylinder, block, something flat, etc.) xav tau kev txhawb nqa kom tsis txhob poob, hnyav, los sis yaj rau hauv txheej dhau los.
Nyob rau hauv Tweaking thiab Slicing kom Zoo 3D Prints, Sherri Johnson, ntawm CatzPaw Innovations, ib lub tuam txhab tsim thiab 3D prints nplai qauv accessories siv rau Model Railroad layouts, piav qhia ntxiv yuav ua li cas ntxiv kev txhawb nqa manually hauv CAD program thaum tus qauv tsim, lossis los ntawm kev siv qhov nws hu ua theem ua haujlwm nrog cov software tshwj xeeb, los yog hauv lub sij hawm luam tawm uas siv cov software slicing.
Hauv no ncej, Kuv xav tshawb nrhiav seb koj rhuav tshem tag nrho cov nyiaj yug ntawd. Raws li koj pom hauv daim duab saum toj no, nws muaj ob yam khoom (ob qho tib si nrog Voronoi Daim duab los yog Qauv ) thiab ob lub pob liab liab qhia cov qauv cuab kev tshaj plaws. Hauv cov rooj plaub no, cov ntaub ntawv lom zem ntau heev thaum kuv siv kuv tus ntiv tes.
Tom qab ntawd, kuv siv ib lub poom pliav rau qee yam ntawm nws thiab ib qho riam uas muaj qhov riam uas muaj ntse rau ib qho ntawm nws. Ntau tus neeg hais tias Xacto cov riam, tab sis txawm ntau ntau nws vim tias ib qho ntawv ua tiav hauv cov ntiv nplhaib thiab ntshav ntawm koj cov ntawv luam tawm 3D. Bummer.
Qhov yooj yim tshaj plaws kom tshem tawm cov kev them nyiaj yug yog mus yuav ib tug dual lub tshuab luam ntawv dual-extruder vim hais tias koj tuaj yeem thauj tus txheem PLA lossis ABS khoom rau cov thawj extruder thiab cov khoom ntim qis rau lwm qhov. Cov khoom txhawb ntawd feem ntau yog dissolvable nyob rau hauv ib cov tshuaj dej da dej. Lub Stratasys Mojo uas kuv siv rau hauv 3DRV roadtrip muaj hom kab no. Lus hauv no teb Qab zib, tab sis alas nws yog tsuas yog ib cov crediter ntaus ntawv rau qhov project thiab, raws li kuv pom, rau kuv tus kheej thiab lwm tus, tsis nco ntsoov hauv kev siv nyiaj rau cov neeg siv hobbyist.
Yog tias koj tab tom tsim koj tus kheej khoom los yog yuav khoom ib yam khoom tiav los ntawm 3D printing service bureau , xws li Shapeways, ces koj tuaj yeem xaiv cov qib uas koj xav tau, yog li muaj lwm tus neeg ua haujlwm tiav rau koj.
Tab sis, feem ntau ntawm peb yog mus rau manually yuav tsum tau ua cov txheej txheem txhawb nyob rau hauv ib txoj kev. Ntxiv nrog rau txoj kev siab tshaj plaws saum toj no, ntawm no yog ib co tswv yim ntxiv thiab cov tswv yim uas kuv tau txais los ntawm kev nyeem ntawv sib txawv. Ib qho uas kuv nyiam tshaj yog nyob rau 3D Hub: Txoj Kev Zoo Tshaj Tawm Cov Khaub Ncaws, Kev Txhawb Nqa, thiab Lwm Yam Txaus Lawm.
Feem ntau ntawm cov lus qhia muaj feem xyuam nrog cov theem ua ntej koj yuav ua tau raws li Sherri Johnson pom zoo - ntxiv cov kev pabcuam zais zuj zus los ntawm kev tshaj lij software: Simplify3D, ib qho kev them nyiaj, them nyiaj los ntawm cov kws tshaj lij. Freeware, xws li, Meshmixer los yog Netfabb muaj ob lum ntawm no.
- Thaum siv rab riam los yog khib nyiab, xws li cua sov cov qauv los yog cov hniav ua kom yooj yim dua. Ib lub hnab me me tuaj yeem pab tau (ua tib zoo saib, rau koj tus qauv).
- Sandpaper yuav ua haujlwm zoo. TAYLOR Landry, Tus Thawj Coj ntawm Kev Tshawb Fawb rau MatterHackers tau hais tias ntub zom zom zom cov nplaum zeb - 220 txog 1200 yuav tshem tawm cov qauv thiab txhuam koj qauv. Nws ntxiv "tias qhov zoo tshaj plaws txhuam peb tau pom tau los ntawm tumbling qhov chaw nyob rau hauv ib lub tshuab siv siv tooj ntsia hlau ua luam. (Stainless hlau yuav siv tau rau hauv cov favers SS). Yog li ntawd, yog tias koj siv cov kab txawv cov ntsej muag, sim lub tumbler. (LINK LINK rau protopasta)
- Nrog PLA koj tuaj yeem tau txais cov kev nyuab siab qhov chaw uas cov ntaub ntawv txhawb los ntawm cov qauv thiab ib tus neeg pom tias tus ntsia thawv polish vanish kom patch khawb thiab cov qhab nia.
- Yog tias koj tuaj koom kev khiav haujlwm hauv koj lub tshuab luam ntawv 3D xws li ib tus kws kho hniav, tau ib qho cuab yeej me me uas hu ua Dremel. Cov handheld grinders, nrog ntau yam khoom thiab cov ntawv txuas, tuaj yeem tsim cov khoom txhawb yooj yim. Yog tias koj tsis muaj tes zoo li tus kws phais lossis tus kws kho hniav, yuav tsum ceev faj txog kev tsim khoom yas yooj yim rau koj.
Kuv muaj ib lub pob zeb ntaus ntawv tumbler uas kuv yuav sim ua ib txoj kev los tshem tawm cov qauv hauv kev txhawb nqa thiab qhia rov qab.
