Padzakhala pafupifupi 0. 05 ~ 0.1 mm interlayer step zotsatira pamwamba pa zigawo zopangidwa ndiStereolithography Apparatus (SLA), ndipo zidzakhudza maonekedwe ndi ubwino wa ziwalozo.Choncho, kuti mupeze mawonekedwe osalala pamwamba, m'pofunika kupukuta pamwamba pa workpiece ndi sandpaper kuchotsa kapangidwe pakati pa zigawo.Njirayi ndiyoyamba kugwiritsa ntchito sandpaper ya 100-grit popera, kenaka kusintha pang'onopang'ono kukhala sandpaper yabwino kwambiri mpaka itapukutidwa ndi sandpaper ya 600-grit.Malingana ngati sandpaper yasinthidwa, ogwira ntchito amayenera kutsuka gawolo ndi madzi ndi mpweya ndiyeno liume.
Pomaliza, kupukuta kumagwira ntchito mpaka pamwamba pake pawala kwambiri.M'kati kusintha sandpaper ndi pang'onopang'ono akupera, ngati nsalu mutu ankawaviika ndi kuwala kuchiritsa utomoni ntchito misozi pamwamba pa mbali, kuti madzi utomoni amadzaza masitepe interlayer ndi maenje ang'onoang'ono, ndiyeno irradiates ndi ultraviolet. kuwala.The yosalala nditransparent prototypezitha kupezeka posachedwa.
Ngati pamwamba pa workpiece ikufunika kupopera utoto ndi utoto, gwiritsani ntchito njira zotsatirazi kuthana nazo:
(1) Choyamba lembani masitepe pakati pa zigawo ndi putty.Mtundu uwu wa zinthu za putty umafunika kuti ukhale ndi kachulukidwe kakang'ono, kugwira ntchito bwino kwa mchenga, komanso kumamatira bwino ku prototype ya utomoni.
(2) Thirani utoto wapansi kuti mutseke mbali yotulukira.
(3) Gwiritsani ntchito sandpaper yamadzi yopitilira 600-grit ndi mwala wopera kuti mupukutire makulidwe a ma microns angapo.
(4) Gwiritsani ntchito mfuti yopopera kupopera pamwamba pa 10 μm.
(5) Pomaliza, sulani chithunzicho kuti chikhale pagalasi lokhala ndi zopukutira.
Pamwambapa ndi kusanthula kwa3D kusindikizakukonza ndi kupanga magawo, ndikuyembekeza kukupatsani chidziwitso.
