Muaj ntau yam ntaub ntawv siv hauv 3D luam ntawv prototypes. 3D luam ntawv yog hloov tau txaus los tso cai rau cov tuam txhab txiav txim siab cov duab, kev ntxhib los mos thiab lub zog ntawm cov khoom. Piv nrog rau txoj kev tsim khoom ib txwm muaj, cov kauj ruam ntau lawm luv luv. Ntxiv mus, cov khoom no tuaj yeem ua nrog ntau hom 3D luam ntawv qauv cov ntaub ntawv.
1. Cov khoom siv yas
Ntawm tag nrho cov ntaub ntawv raw siv rau 3D luam ntawv prototypes niaj hnub no, yas yog qhov ntau tshaj plaws. Nrog nws cov firmness, yooj, smoothness thiab ntau yam ntawm cov xim kaj, qhov kev thov ntawm cov yas yog yooj yim to taub.
Cov khoom yas feem ntau yog tsim los siv FDM tshuab luam ntawv, qhov twg thermoplastic filaments yog yaj thiab tsim rau hauv cov txheej txheem los ntawm txheej. Hom yas siv hauv cov txheej txheem no feem ntau yog tsim los ntawm ib qho ntawm cov ntaub ntawv hauv qab no:
◆ Polylactic acid (PLA): PLA yog ib qho kev xaiv zoo tshaj plaws rau cov tshuab luam ntawv 3D, nws yog muab los ntawm cov khoom ntuj xws li qab zib cane thiab pob kws, yog li nws yog biodegradable. Cov yas ua los ntawm cov tawv tawv thiab cov kua qaub tuaj rau hauv cov ntaub ntawv mos thiab tawv thiab xav tias yuav ua tus thawj coj ntawm 3D luam ntawv kev lag luam hauv xyoo tom ntej. Rigid PLA yog cov khoom siv muaj zog thiab yog li ntawd zoo tagnrho rau ntau yam khoom siv.
◆ Acrylonitrile Butadiene Styrene (ABS): Muaj nuj nqis rau nws lub zog thiab kev nyab xeeb, ABS yog qhov kev xaiv nrov rau tsev 3D tshuab luam ntawv. Kuj hu ua "Lego yas," cov khoom muaj xws li pasta-zoo li filaments uas muab ABS nws ruaj khov thiab yooj.
◆ Polycarbonate (PC): Polycarbonate tsis yog feem ntau siv piv rau cov yas saum toj no, nws tsuas yog ua haujlwm hauv 3D tshuab luam ntawv nrog lub nozzle tsim uas ua haujlwm ntawm qhov kub thiab txias. Ntawm lwm yam, polycarbonate yog siv los ua cov yas qis qis thiab ua cov tais.
2. Cov khoom siv hlau
Hauv kev lag luam 3D luam ntawv, cov khoom siv nrov tshaj plaws yog hlau, uas yog siv los ntawm cov txheej txheem hu ua direct hlau laser sintering lossis DMLS / SLM. DMLS cov tshuab luam ntawv kuj tseem thov rau cov tuam txhab tsim cov khoom lag luam uas tuaj yeem luam tawm 3D sai dua thiab ntau dua - txhua yam tsis tas yuav tsum tau ua haujlwm ntev, nthuav dav.
3D luam ntawv ntawm hlau kuj tau qhib lub qhov rooj rau cov neeg tsim tshuab kom nws thiaj li siv DMLS los tsim ntawm qhov nrawm thiab ntim tsis tuaj yeem ua tiav nrog cov cuab yeej sib dhos tam sim no. Cov neeg tawm tswv yim ntawm cov kev txhim kho no sib cav tias 3D luam ntawv yuav tso cai rau cov neeg tsim tshuab tsim cov hlau uas muaj zog dua li cov khoom siv los ntawm cov hlau ua kom zoo.
Qhov ntau ntawm cov hlau haum rau DMLS thev naus laus zis yog ntau haiv neeg raws li ntau yam 3D tshuab luam ntawv yas hom:
◆ Stainless Hlau: Zoo tagnrho rau kev luam ntawv cov tais diav, cookware thiab lwm yam khoom uas tej zaum yuav mus cuag dej.
◆ Bronze: tuaj yeem siv los ua cov vases thiab lwm yam khoom siv.
◆ Kub: Zoo tagnrho rau cov nplhaib, qhwv ntsej, bracelets thiab necklaces.
◆ Aluminium: Zoo rau cov khoom siv hlau nyias.
◆ Titanium: Sturdy, thawj qhov kev xaiv rau cov khoom siv ruaj khov.
3. Cov khoom siv hmoov
Niaj hnub no cov tshuab luam ntawv 3D qib siab dua siv cov khoom siv hmoov los tsim cov khoom. Nyob rau hauv lub tshuab luam ntawv, cov hmoov yog yaj thiab muab faib rau hauv cov khaubncaws sab nraud povtseg kom txog rau thaum lub thickness xav tau, kev ntxhib los mos thiab qauv tiav. Cov hmoov no tuaj yeem los ntawm ntau qhov chaw thiab cov khoom siv, tab sis feem ntau yog:
◆ Polyamide (Nylon): Nrog nws lub zog thiab yoog raws, polyamide muab a
qib siab ntawm kev nthuav dav ntawm 3D luam tawm qauv khoom. Cov khoom siv tshwj xeeb yog tsim los siv rau hauv 3D luam ntawv qhov chaw thiab cov khoom sib txuas hauv cov qauv.
◆ Aluminium hmoov: Muaj kev sib xyaw ntawm polyamide thiab grey aluminium,
txhuas hmoov tuaj yeem siv rau hauv qee qhov muaj zog tshaj 3D luam tawm qauv. Pom zoo rau nws cov granular thiab xuab zeb zoo li, cov hmoov tuaj yeem siv rau hauv cov qauv kev lag luam thiab cov qauv.
◆ Hauv daim ntawv hmoov, cov ntaub ntawv xws li hlau, tooj liab thiab lwm yam hlau yog
yooj yim rau kev thauj mus los thiab ua kom zoo rau hauv cov duab uas xav tau. Zoo li ntau yam plastics siv nyob rau hauv 3D luam ntawv prototypes, cov hmoov hlau yuav tsum tau rhuab mus rau lub ntsiab lus uas nws muaj peev xwm muab faib ua txheej los ntawm txheej los tsim tag nrho cov duab.
4. Cov khoom siv cob
Resins yog tsim los ntawm cov kua polymers uas ncav cuag lawv lub xeev kawg thaum raug UV teeb. Cov resin feem ntau pom muaj xim dub, dawb thiab meej, tab sis qee qhov luam tawm kuj ua rau txiv kab ntxwv, liab, xiav thiab ntsuab. Cov khoom raug muab faib ua peb pawg hauv qab no:
◆ High Detail Resin: Feem ntau yog siv rau cov qauv me me uas xav tau kev sib tw
paub meej. Piv txwv li, plaub-nti figurines nrog intricate wardrobe thiab lub ntsej muag cov ntsiab lus feem ntau luam tawm nyob rau hauv no qib ntawm resin.
◆ Paintable resins: Qee zaum siv hauv 3D luam ntawv du nto, cov resins paub txog lawv qhov zoo nkauj.
◆ Clear Resin: Qhov no yog cov khoom muaj zog tshaj plaws, yog li nws yog qhov zoo tshaj plaws rau ntau yam ntawm 3D luam ntawv. Feem ntau yog siv rau cov qauv uas yuav tsum tau suffocating thiab muaj ib tug pob tshab tsos.
