(1) Low viscosity.Kurapa kweUV kunoenderana neCAD modhi, uye resin inoiswa laminated layer ne layer kuti iite zvikamu.Mushure mekupedzwa kwekutanga, zvinonetsa kuti resin yemvura ivhare otomatiki pamusoro peiyo yakaporeswa yakasimba resin, nekuti kudzvinyirirwa kwepamusoro kweresin kwakakura kupfuura kweiyo yakasimba resin.Iyo resin level inofanirwa kukweshwa uye yakaputirwa kamwe chete neatomatiki scraper, uye iyo inotevera dhizaini inogona kugadziriswa mushure mekunge nhanho yaiswa.Izvi zvinoda kuti resin ive yakaderera viscosity kuti ive nechokwadi chekuyera kwayo uye nyore kushanda.Parizvino, viscosity ye resin inowanzodiwa kuti ive pasi pe600 CP · s (30 ℃).
(2) Kupora kuderera kudiki.Chinhambwe chiri pakati pemvura resin mamorekuru chinhambwe chevan der Waals force, chinenge 0.3~0.5 nm.Mushure mekurapa, iwo mamorekuru crosslink, uye iyo intermolecular chinhambwe kuti igadzire network chimiro inoshandurwa kuita covalent bond chinhambwe, chingangoita 0.154 nm.Zviripachena, chinhambwe pakati pemamorekuru chinodzikira pamberi uye mushure mekurapa.Iyo intermolecular chinhambwe chekuwedzera polymerization reaction ichaderedzwa ne 0.125 ~ 0.325 nm.Mukati mekuchinja kwemakemikari, C = C inova CC, kureba kwechisungo kunowedzera zvishoma, asi mupiro wekuchinja kwe intermolecular interaction distance iduku zvikuru.Naizvozvo, kuderera kwehuwandu mushure mekurapa hazvidzivisike.Panguva imwecheteyo, kusati kwapera uye mushure mekurapa, kusagadzikana kunowedzera kurongeka, uye kuderera kwevhoriyamu kunoitikawo.Izvi hazvina kunaka kune iyo shrinkage molding modhi, iyo inoburitsa kushushikana kwemukati uye nyore kutungamira kune deformation, warpage uye kuputika kweiyo modhi zvikamu., Uye zvakanyanya kukanganisa kurongeka kwezvikamu.Naizvozvo, kukudziridzwa kwakaderera shrinkage resin ndiro dambudziko guru rakatarisana neSLA resin parizvino.
(3) Kukurumidza kupora kunokurumidza.Kazhinji, ukobvu hwega hwega hunenge 0.1 ~ 0.2 mm, iyo inogona kusimbiswa dhizaini nedhiza panguva yekuumbwa.Zvinotora mazana kusvika kuzviuru zvemitsara kuomesa chikamu chakapedzwa.Naizvozvo, kana iyo yakasimba ichizogadzirwa munguva pfupi, chiyero chekurapa chakakosha zvikuru.Iyo yekuratidzwa nguva yelaser beam kusvika padanho inongori mukati meiyo microseconds kune milliseconds, iyo inenge yakaenzana nehupenyu hwekunakidzwa mamiriro eiyo photoinitiator inoshandiswa.Iyo yakaderera kurapa mwero haingokanganisa maitiro ekurapa, asi zvakare inokanganisa zvakananga kushanda kwemushini wekuumba, saka zvakaoma kushandisa kune kugadzirwa kwekutengesa.
(4) Kuwedzera kwakaderera.Mukuita kwekugadzira mold, iyo resin yemvura inogara yakavhara chikamu chakaporeswa chebasa rekushanda uye inogona kupinda muchikamu chakarapwa, ichiita kuti resin yakarapwa iwedzere, zvichikonzera kuwedzera kwechikamu.Kururama kwemuenzaniso kunogona kuvimbiswa chete kana kuputika kweresin kuduku.
(5) Kunzwa kwakanyanya.Nekuti SLA inoshandisa mwenje wemonochromatic, iyo yavelength yephotosensitive resin uye laser inofanirwa kuenderana, kureva kuti, iyo wavelength yelaser inofanira kunge iri padyo nepaunogona napo kune yakanyanya kunyura wavelength yephotosensitive resin.Panguva imwecheteyo, iyo yekunyudza wavelength yemhando yephotosensitive resin inofanirwa kuve yakamanikana, iyo inogona kuve nechokwadi chekuti kurapa kunoitika chete padanho relaser irradiation, nekudaro kugadzirisa iko kwekugadzira kwezvikamu.
(6) Kurapa kwepamusoro.Inogona kuderedza shrinkage yeiyo post-curing molding modhi, nekudaro ichidzikisa iyo post-kuporesa deformation.
(7) Simba guru remvura.Simba rakanyorova repamusoro rinogona kuve nechokwadi chekuti mushure mekurapa maitiro haaburitse deformation, kuwedzera uye interlayer peeling.
