STL cov ntaub ntawv

STL-cov ntaub ntawv

Txog rau tam sim no, cov ntaub ntawv tau raug ua rau STL cov ntaub ntawv, uas yog lub hauv paus ntawm kab lus no. Txawm li cas los xij, hom ntawv nrov no tseem tsis tau kawm txog qhov tob. Hauv seem no koj yuav tuaj yeem paub nws qhov tob:

STL ntawv yog dab tsi?

Hom ntawm STL-cov ntaub ntawv nws yog cov ntaub ntawv nrog dab tsi 3D tshuab luam ntawv tsav tsheb xav tau, uas yog, kom lub tshuab luam ntawv kho vajtse tuaj yeem luam tawm cov duab uas xav tau, hauv lwm lo lus, nws tso cai rau encode lub geometry ntawm qhov chaw ntawm cov khoom peb-dimensional. Nws tau tsim los ntawm Chuck Hull ntawm 3D Systems hauv xyoo 80s, thiab cov ntawv sau tsis meej tag nrho.

Geometric encoding tuaj yeem hloov kho los ntawm Tessellation, interposing geometric duab nyob rau hauv xws li ib txoj kev uas tsis muaj overlaps los yog qhov chaw, uas yog, zoo li ib tug mosaic. Piv txwv li, cov duab tuaj yeem tsim los siv cov duab peb sab, ib yam li cov ntaub ntawv nrog GPU rendering. Ib qho zoo mesh uas muaj cov duab peb sab yuav ua rau tag nrho saum npoo ntawm tus qauv 3D, nrog rau cov duab peb sab thiab cov kev sib koom ua ke ntawm lawv 3 cov ntsiab lus.

Binary STL vs ASCII STL

Nws txawv ntawm STL hauv binary hom thiab STL hauv ASCII hom. Ob txoj hauv kev khaws cia thiab sawv cev cov ntaub ntawv ntawm cov vuas no thiab lwm yam tsis muaj. A ASCII format piv txwv yuav yog:

solid <nombre>

facet normal nx ny nz
outer loop
vertex v1x v1y v1z
vertex v2x v2y v2z
vertex v3x v3y v3z
endloop
endfacet

endsolid <nombre>

Qhov twg "vertex" yuav yog cov ntsiab lus tsim nyog nrog lawv cov kev tswj hwm XYZ. Piv txwv li, tsim ib tug kheej kheej, koj tuaj yeem siv qhov no Piv txwv li ASCII code.

Thaum 3D duab yog qhov nyuaj lossis loj, nws yuav txhais tau tias muaj ntau daim duab peb sab me me, txawm tias qhov kev daws teeb meem siab dua, uas yuav ua rau cov duab peb sab me me kom du cov duab. Qhov ntawd tsim cov ntaub ntawv ASCII STL loj heev. Yuav kom compact nws, peb siv STL hom ntawv binaries, xws li:

UINT8[80] – Header                               - 80 bytes o caracteres de cabecera
UINT32 – Nº de triángulos                    - 4 bytes
for each triangle                                        - 50 bytes
REAL32[3] – Normal vector                  - 12 bytes para el plano de la normal
REAL32[3] – Vertex 1                              - 12 bytes para el vector 1
REAL32[3] – Vertex 2                             - 12 bytes para el vector 2
REAL32[3] – Vertex 3                             - 12 bytes para el vector 3
UINT16 – Attribute byte count              - 2-bytes por triángulo (+2-bytes para información adicional en algunos software)
end

Yog koj xav tau, ntawm no koj muaj cov ntaub ntawv STLB los yog piv txwv binary STL rau daim ntawv ib qho yooj yim kub.

Thaum kawg, yog koj xav tias zoo dua ASCII lossis binary, qhov tseeb yog tias binaries yeej ib txwm pom zoo rau 3D luam ntawv vim lawv qhov me me. Txawm li cas los xij, yog tias koj xav tshuaj xyuas cov cai thiab debug nws manually, ces koj tsis muaj lwm txoj hauv kev los ua nws dua li siv ASCII thiab hloov kho, vim nws yog qhov xav tau ntau dua los txhais.

  • M140 thiab M190: zoo ib yam li ob qho dhau los, tab sis lawv tsis muaj qhov ntsuas T, txij li qhov no nws hais txog qhov kub ntawm lub txaj.

Tau kawg, qhov G-Code no ua haujlwm rau FDM hom tshuab luam ntawv, txij li cov resin sawv daws yuav xav tau lwm yam tsis, tab sis nrog rau cov piv txwv no nws yog txaus rau koj to taub yuav ua li cas nws ua hauj lwm.

Hloov ua lwm yam: STL rau…

Hloov ua lwm yam ntaub ntawv STL

Thaum kawg, lwm yam uas ua rau muaj kev tsis ntseeg siab tshaj plaws ntawm cov neeg siv, muab tus naj npawb ntawm cov qauv sib txawv uas muaj nyob, ntxiv cov qauv 3D CAD, thiab cov lej tsim los ntawm cov kab sib txawv, yog yuav hloov pauv li cas ntawm ib qho mus rau lwm qhov. Ntawm no koj muaj qee qhov kev hloov pauv uas xav tau tshaj plaws:

Yog tias koj ua Google tshawb nrhiav, koj yuav pom tias muaj ntau qhov kev pabcuam hloov pauv hauv online, xws li AnyConv lossis MakeXYZ, uas tuaj yeem hloov pauv yuav luag txhua hom, txawm tias tsis yog txhua tus ua haujlwm tau zoo, thiab tsis yog txhua tus ntawm lawv yog dawb.
  • Hloov ua lwm yam STL rau GCode: Nws tuaj yeem hloov nrog slicing software, vim nws yog ib qho ntawm nws lub hom phiaj.
  • Mus los ntawm STL rau Solidworks: tuaj yeem ua tiav nrog Solidworks nws tus kheej. Qhib > hauv cov ntaub ntawv explorer hloov mus rau hom STL (*.stl) > xaiv > hloov import as a lub cev muaj zog o khoom nto > txais > xauj thiab nyem rau ntawm STL koj xav import > Qhib > tam sim no koj tuaj yeem pom cov qauv qhib thiab cov yam ntxwv ntoo ntawm sab laug> Txawv Tebchaws > FeatureWorks > Paub cov yam ntxwv > thiab yuav tau npaj.
  • Hloov cov duab rau STL lossis JPG/PNG/SVG rau STL: Koj tuaj yeem siv cov kev pabcuam online xws li Imagetostl, Selva3D, Smoothie-3D, thiab lwm yam, lossis siv qee cov cuab yeej AI, thiab txawm tias software zoo li Blender thiab lwm yam, los tsim cov qauv 3D los ntawm cov duab thiab tom qab ntawd xa mus rau STL.
  • Konvertiere STL in DWG: Nws yog CAD cov ntaub ntawv, thiab ntau CAD tsim software siv tau los ua qhov hloov dua siab tshiab. Piv txwv li:
    • AutoCAD: Tso zis> Xa> Export> sau cov ntaub ntawv npe> xaiv hom Lithography (*.stl)> Txuag.
    • SolidWorks: Cov ntaub ntawv> Txuag Raws li> Txuag Raws li STL> Kev Xaiv> Kev daws teeb meem> Fine> OK> Txuag.
  • Los ntawm OBJ rau STL: Ob qhov kev pabcuam hloov pauv hauv online tuaj yeem siv tau, nrog rau qee qhov software hauv zos. Piv txwv li, nrog Spin3D koj tuaj yeem ua cov hauv qab no: Ntxiv cov ntaub ntawv> Qhib> xaiv ib lub hom phiaj nplaub tshev hauv Txuag hauv nplaub tshev> Xaiv cov hom ntawv tso zis> stl> nias Hloov khawm thiab tos cov txheej txheem kom tiav.
  • Mus los ntawm Sketchup rau STL: Koj tuaj yeem ua nws nrog Sketchup nws tus kheej hauv txoj hauv kev yooj yim, vim nws muaj ob qho tib si ntshuam thiab xa tawm. Hauv qhov no koj yuav tsum tau xa tawm los ntawm kev ua raws li cov kauj ruam thaum koj muaj cov ntaub ntawv Sketchup qhib: Cov Ntaub Ntawv> Export> 3D Qauv> xaiv qhov twg los cawm STL> Txuag li STereolithography Cov Ntaub Ntawv (.stl)> Export.
