Stereolithography (SLA) - Doorashada ugu Fiican ee Daabacaadda 3D ee Saxnaanta Sare leh
Stereolithography (SLA ama SL) waa tiknoolajiyad daabacan oo 3D ah oo sax ah oo adeegsanaysa resin xasaasi ah oo sawireed ahaan ah. Tiknoolajiyaddani waxay ka faa'iidaysataa sifooyinka bogsashada degdegga ah ee resin xasaasi ah iyadoo la adeegsanayo shucaaca laser-ka UV ee hirarka gaarka ah, taasoo suurtogalinaysa soo saarista hufan ee qaab-dhismeedka 3D ee adag iyada oo loo marayo sameynta lakab-lakab.
Inta lagu jiro habka wax soo saarka, resin-ka dareeraha ah ee sawir-qaadista ayaa si degdeg ah u mara polymerization iyo adkeysi marka la kulmo iftiinka UV (dhererka hirarka qiyaastii 250-400nm). Mashiinka SLA wuxuu si sax ah u diiradda saaraa leysarka UV dusha sare ee resin-ka sawir-qaadista, isagoo si tartiib tartiib ah u bogsiinaya resin-ka min dhibic ilaa xariiq ka dibna xariiq ilaa dusha sare, isagoo gaaraya sawirro sax ah oo isdhaafsi ah oo lakab kasta ah. Lakab ahaan, qaab 3D ah oo adag oo faahfaahsan ayaa la dhisay.
Stereolithography waxay bixisaa faa'iidooyin sida saxnaanta qaabaynta sare, dusha siman, iyo soo saarista faahfaahinta xallinta sare leh. Waxaa si weyn loogu isticmaalaa sameynta moodooyinka warshadaha, naqshadeynta qalabka caafimaadka, naqshadeynta dahabka, soo saarista caaryada, iyo qaab-dhismeedka heerka sare ah. Sameynteeda degdega ah iyo saxda ah waxay si weyn u gaabinaysaa wareegyada horumarinta badeecadaha, taasoo u keenaysa dabacsanaan iyo hal-abuur weyn warshadaha wax soo saarka.
SLA (Stereolithography) ma aha oo kaliya tignoolajiyad muhiim ah oo ku saabsan daabacaadda 3D, laakiin sidoo kale waa xal aad waxtar u leh oo lagu gaarayo tijaabinta tayada sare leh iyo wax soo saar yar oo loo habeeyay dufcad, taasoo ka caawinaysa shirkadaha inay gaaraan heerar sare oo wax soo saar sax ah.
Resins-ka Xagjirka ah ee Sawir-qaadista Xagjirka ah ee Bilaashka ah:
Faa'iidooyinka: Qiimo jaban, daaweyn degdeg ah, adkeysi wanaagsan, dheellitir yar
Qasaarooyinka: Joojinta oksijiinta ee muhiimka ah, yaraanta sare, leexashada alaabada daabacan, saxnaanta hoose, iyo baahida loo qabo bogsashada labaad
Resin-yada Sawir-qaadista ee Cationic Photosensitive:
Faa'iidooyinka: Hoos u dhac yar oo mugga ah marka la bogsado, heerka falcelinta sare, looma baahna bogsashada labaad ka dib qaabaynta, saameyn kuma yeelanayso joojinta oksijiinta, xasillooni cabbir wanaagsan, sifooyin farsamo oo heer sare ah, iyo saxnaan sare
Qasaarooyinka: Heerka falcelinta gaabiska ah, dheellitirka sare, vinyl ethers-ku waxay leeyihiin qiyaas sare oo soo-gaadhis ah waxayna si tartiib tartiib ah u bogsadaan; epoxies-ku waa jilicsan yihiin
Nidaamyada Isku-dhafka ah:
Nidaamyada isku-dhafka ah ee Acrylate-epoxy waxay isku daraan labada mabda' ee kor ku xusan ee daaweynta, iyadoo ay wada shaqeynayaan bilaabayaasha cationic iyo kuwa xorta ah.
Resins-ka daabacaadda 3D waxaa loo kala saaraa resins-ka sawir-qaadista xorta ah ee xagjirka ah, resins-ka sawir-qaadista ee cationic, iyo nidaamyada isku-dhafka ah. Ever Ray, oo ah soo-saare leh 20 sano oo waayo-aragnimo ah oo ku takhasusay soo saarista iyo horumarinta resins-ka sawir-qaadista leh, wuxuu leeyahay awood wax-soo-saar sannadle ah oo ah 20,000 tan, khad badeecadeed oo dhammaystiran, iyo awoodda lagu habeeyo alaabada. Resins-ka daabacaadda 3D waxaa ka mid ah Polyurethane 7224-1, 7200, 7296-1, iyo 7253A-5.
