SLA / DLP resin-based 3D printers muaj kev sib txuam siab heev
Cov qauv ntawv 3D printers hnub no yog siv cov qauv fused deposition modeling (FDM) txoj kev, nrog ib qho extruder, kub kawg, raws li lawv raug hu ntau, kom yaj ib lub hnab yas (yas). Nws muaj lwm qeb uas yog muaj kev paub zoo tias cov duab luam duab.
Cov 3D reag printers siv cov stereolithography (SLA) lossis digital light processing (DLP) raws li txoj hauv kev uas lawv tsim cov khaubncaws sab nraud povtseg. Hloov ntawm lub pob zeb ntawm lub hnab yas, cov tshuab luam yeeb siv lub teeb los kho lub teeb ci ntsa iab, kua photopolymer.
Ntau lub tshuab luam ntawv aficionados hais tias DLP / SLA cov ntaub ntawv muab kev daws teeb meem zoo dua thiab ntau dua qub, tiam sis cov ntawv luam tawm 3d luam ntawv yog feem ntau dua. Txawm li cas los xij, DLP thiab SLA cov luam ntawv luam tawm ob tsab luam tawm sai dua li cov qauv luam tawm hluav taws xob. Hauv ob peb lub xyoos dhau los, peb tau pom ntau FDM 3D printers tau pib ntawm cov neeg coob coob. Tam sim no peb pom ntau dua 3d luam ntawm Kickstarter thiab IndieGoGo, piv txwv.
Vim cov DLP thiab SLA luam tawm ob leeg siv cov photopolymers uas tawv tau thaum UV teeb pom kev, cov resins feem ntau sib cuam tshuam hauv cov tshuab luam ntawv. Uas tau sib cav, ntawm chav kawm, los ntawm lub tuam txhab uas xav kom koj tsuas siv lawv cov resins. Koj yuav tsum tau ceev faj koj tsis yog kev tiv thaiv koj qhov warranty, yuav tsum paub meej, raws li kuv tsis paub txog cov lus sib txawv no. Nyeem cov ntawv nplua!
Cov duab thaij duab 3D printers, nws muaj peb hom hom tawv ntoo - txheem, castable, thiab yoog raws. Kuv hu lawv cov qauv resins, tab sis koj yuav pom cov neeg ua haujlwm feem ntau yog hu lawv cov "siab dav resins" los yog "high resolution resin." Ncaj ncees txaus.
- Cov ntaub ntawv qhia txog ntau yam muaj ntau hom xim xaiv. Piv txwv, Formlabs muaj cov ntsiab lus meej, dawb, grey, los yog dub. Nyob rau hauv Amazon Additive Raug Khoom seem ntawm lawv "3D tshuab luam ntawv" muaj ntau yam xim xaiv los ntawm MadeSolid thiab MakerJuice.
- Castable cob los ntawm MadeSolid yog siv rau kev nrum. Qhov no re nplooj tawm tsis tshauv, uas ua rau nws zoo tagnrho rau peev casting. Nws kuj muaj qhov tsawg kawg nkaus expansion thiab ntsws kom txog thaum muaj kev kub ntxhov. Nws yog tsim los nrog cov hniav nyiaj hniav kub hauv lub hlwb thiab siv tau nrog feem ntau ntawm cov tshav kub lub sijhawm uas siv los ntawm cov kev ua cov peev nyiaj rau cov hniav nyiaj hniav kub. Asiga kuj ua haujlwm rau SuperWAX, ib yam li photopolymer uas siv tau thaum casting platinum.
- Yog hais tias koj xav tsim kom muaj kev sib txuas lus uas xav tau kev pab ntau dua li cov qauv coj, MakeSolid muaj Vorex. Tam sim no, nws tsuas muaj nyob rau hauv cov txiv kab ntxwv los yog dub, tab sis thaum nws lub zog tensile yog multiplied los ntawm nws cov elongation, nws yuav tsum tau ntau dua cov zog kom tawg dua lwm cov resins. MakeSolid tsim nws rau durability thiab feem xyuam.
- Qee cov resins muaj kev tiv thaiv kev kub-txias, xws li Accura Bluestone thiab SOMOS 9120 (uas yog tshuaj tiv thaiv) ntawm Proto3000 los yog Asiga's FusionGRAY. Feem ntau hi-temp resins mob kom sov kub txaus kom tsim tau vulcanized, rubber molds thiab siv nyob rau hauv industrial applications.
- Txij li 3D printing yog tseem siv los ntawm kev kho mob kev lag luam los tsim cov kev ua haujlwm, kev kho mob tshwj xeeb, qhov xav tau rau saj zawg zog rein yog qhov zoo. Formlabs Saj zawg zog Resin thiab MakerJuice tus SF khoom kab ob leeg nyob twj ywm thaum uas kho. Asiga's Bio Kab Aplike photopolymer tseem nyob hauv txoj kev loj hlob. Vim nqaij tawv, cov khoom siv xws li hnov pob ntseg yuav tsum tau ua los ntawm cov pob tshwj xeeb. Asiga xav tso cai rau cov ntawv luam tawm uas yuav tsis ua kom tawv nqaij txawm tias thaum ntaus ntawv hu nws txhua hnub ntev.
- Autodesk ua tswvcuab hauv daim ntawv cob qhia Ember 3D tshuab luam ntawv. Lawv ua lawv cov ntaub ntawv, Standard Prototyping Resin (PR48) yog lub npe, tab sis koj siv tau lwm cov resins nrog lawv lub tshuab luam ntawv.
Ntxiv dua thiab, nws yog ib qho tseem ceeb kom kuaj cov lus sib tw nrog koj hom kev luam ntawv ua ntej yuav txais cov khoom noj. Txawm li cas los xij, feem ntau ntawm cov resins tau tsim los siv nyob rau hauv txhua lub tshuab luam ntawv 3D uas siv UV rays los kho kua dej.
Qee cov ntaub ntawv yuav tsum tau txhaj UV ntxiv tom qab lawv luam tawm, tab sis qhov no ua rau cov khoom siv zaum kawg. Txawm tias SLA thiab DLP cov ntawv luam tawm 3D tsis tau los txog qhov txawv txav ntawm extrusion printers, tseem muaj ntau ntau yam, thiab ntau cov ntaub ntawv yog ntawm txoj kev.
