Taw qhia rau 3D luam ntawv:
3D printing yog dab tsi?
3D luam ntawv yog ib qho kev siv thev naus laus zis siv los tsim khoom.Nws yog 'additive' nyob rau hauv uas nws tsis xav tau ib qho thaiv ntawm cov khoom siv los yog pwm los tsim cov khoom siv lub cev, nws tsuas yog stacks thiab fuses txheej ntawm cov khoom.Nws feem ntau yog nrawm, nrog cov nqi teeb tsa qis, thiab tuaj yeem tsim cov geometries nyuaj dua li 'ib txwm' thev naus laus zis, nrog rau cov npe ntawm cov ntaub ntawv nthuav dav.Nws yog siv dav hauv kev lag luam engineering, tshwj xeeb tshaj yog rau prototyping thiab tsim lub teeb geometry.
3D printing thiab ceev prototyping
'Rapid prototyping' yog lwm kab lus uas qee zaum siv los xa mus rau 3D luam ntawv thev naus laus zis.Qhov no yog hnub rov qab mus rau keeb kwm thaum ntxov ntawm 3D luam ntawv thaum cov thev naus laus zis tau tshwm sim thawj zaug.Nyob rau xyoo 1980, thaum 3D tshuab luam ntawv tau tsim thawj zaug, lawv tau raug xa mus rau cov cuab yeej siv hluav taws xob sai vim tias rov qab siv tshuab tsuas yog tsim rau cov qauv, tsis yog cov khoom tsim.
Nyob rau hauv xyoo tas los no, 3D luam ntawv tau matured rau hauv ib qho kev daws teeb meem zoo heev rau ntau yam khoom siv, thiab lwm yam kev tsim khoom siv tshuab (xws li CNC machining) tau ua pheej yig dua thiab siv tau rau kev tsim qauv.Yog li thaum qee tus neeg tseem siv 'prototyping nrawm' los xa mus rau 3D luam ntawv, cov kab lus tau hloov zuj zus mus rau txhua hom kev tsim qauv sai heev.
Qhov sib txawv ntawm 3D luam ntawv
3D tshuab luam ntawv tuaj yeem muab faib ua ib qho ntawm ntau hom txheej txheem:
Vat Polymerization: kua photopolymer yog kho los ntawm lub teeb
Cov Khoom Siv Extrusion: molten thermoplastic yog tso los ntawm lub tshuab cua sov
Powder Bed Fusion: Cov hmoov hmoov yog fused los ntawm lub zog siab
Khoom Siv Jetting: tee dej ntawm cov kua photosensitive fusing tus neeg saib xyuas yog tso rau ntawm lub txaj hmoov thiab kho los ntawm lub teeb
Binder Jetting: cov tee ntawm cov kua binding tus neeg sawv cev tau tso rau ntawm lub txaj ntawm cov ntaub ntawv granulated, uas tom qab sintered ua ke
Direct Energy Deposition: molten hlau ib txhij tso thiab fused
Sheet Lamination: ib daim ntawv ntawm cov khoom raug txiav kom zoo thiab laminated ua ke
