Stereolithography (SLA) - Sarudzo Yakakodzera Yekudhinda Kwemhando Yepamusoro-soro mu3D
Stereolithography (SLA kana SL) tekinoroji yekudhinda ye3D yakanyatsogadzirwa inoshandisa resin inopinza chiedza sezvinhu zvakabikwa. Iyi tekinoroji inoshandisa hunhu hweresin inopinza chiedza nekukurumidza pasi pemwaranzi yeUV laser, zvichigonesa kugadzirwa kwezvivakwa zvakaoma zve3D kuburikidza nekugadzirwa kwechikamu nechikamu.
Munguva yekugadzira, resin inonyungudika nechiedza inonyungudika nekukasika kana yaiswa muchiedza cheUV (wavelength inosvika 250-400nm). Muchina weSLA unonyatsotarisa UV laser pamusoro peresin inonyungudika nechiedza, uchigadzirisa resin zvishoma nezvishoma kubva panzvimbo imwe kuenda kune imwe uye kubva pamutsetse kuenda kune imwe, zvichiita kuti pave nemifananidzo chaiyo yechikamu chimwe nechimwe. Chikamu nechikamu, modhi ye3D inogadzirwa.
Stereolithography ine zvakanakira zvakaita sekuumbwa kwakanyatsojeka, nzvimbo dzakatsetseka, uye kugadzirwa kwemhando yepamusoro. Inoshandiswa zvakanyanya mukugadzira mamodheru emaindasitiri, kugadzira zvishandiso zvekurapa, kugadzira zvishongo, kugadzira chakuvhuvhu, uye kugadzira maprototyping emhando yepamusoro. Kugadzirwa kwayo nekukurumidza uye kwakanyatsojeka kunopfupisa zvakanyanya kutenderera kwekugadzirwa kwechigadzirwa, zvichiunza kuchinjika kukuru uye hunyanzvi muindasitiri yekugadzira.
SLA (Stereolithography) haisi tekinoroji yakakosha mukudhinda kwe3D chete, asiwo mhinduro inoshanda zvikuru yekuwana prototyping yemhando yepamusoro uye kugadzirwa kwakagadzirwa nemaoko madiki, zvichibatsira makambani kuwana mwero wepamusoro mukugadzira nemazvo.
MaResins eRadical Photosensitive Resins emahara:
Zvakanakira: Mutengo wakaderera, mushonga unokurumidza, kusimba kwakanaka, kusimba kwakaderera
Zvakashata: Kudziviswa kukuru kweokisijeni, kuderera kwakanyanya, kukanganiswa kwezvigadzirwa zvakadhindwa, kusanyatsojeka, uye kudiwa kwekugadzirisa kwechipiri.
MaResins eCationic Photosensitive:
Zvakanakira: Kudzikira kwevhoriyamu kushoma kana yapera, kumhanya kwakanyanya kwekuita, hapana chikonzero chekugadziriswa kwechipiri mushure mekuumbwa, hakukanganisike nekudziviswa kweokisijeni, kugadzikana kwakanaka kwehukuru, hunhu hwakanaka hwemuchina, uye kunyatsoita zvinhu nemazvo.
Zvakashata: Kunonoka kwekuita, kusviba kwakanyanya, vinyl ethers dzine mwero wakanyanya wekubuda uye kupora zvishoma nezvishoma; ma epoxies haatani kuputsika.
Masisitimu Akasanganiswa:
Masisitimu eAcrylate-epoxy hybrid anobatanidza misimboti miviri yataurwa pamusoro apa yekurapa, pamwe chete nevatangi vecationic nefree radicals vachishanda pamwe chete.
Maresini ekudhinda e3D akakamurwa kuva maresini efree radical photosensitive, maresini ecationic photosensitive, uye masisitimu ehybrid. Ever Ray, mugadziri ane ruzivo rwemakore makumi maviri anonyanya kugadzira nekugadzira maresini anorapika, ane kugona kwekugadzira matani zviuru makumi maviri pagore, chigadzirwa chakakwana, uye kugona kugadzirisa zvigadzirwa. Maresini ekudhinda e3D anosanganisira Polyurethane 7224-1, 7200, 7296-1, uye 7253A-5.
