Stereolithography (SLA kana SL; inozivikanwawo sevat photopolymerisation, optical fabrication, photo-solidification, kanaresin kudhinda imhando ye 3D tekinoroji yekudhinda inoshandiswa kugadzira modhi, prototypes, mapatani, uye zvikamu zvekugadzira mudhizaini nedhizaini fashoni uchishandisa mafotochemical maitiro ayo mwenje unokonzera makemikari monomers uye oligomers kuyambuka-kubatanidza pamwechete kugadzira mapolymer.
Iwo mapolymers anobva agadzira muviri wehutatu-dimensional solid. Tsvagiridzo munzvimbo iyi yakaitwa mukati memakore ekuma1970, asi izwi iri rakagadzirwa naChuck Hull muna 1984 paakanyorera patent pachirongwa ichi, chakapihwa muna 1986. stereolithography inokurumidza uye inogona kugadzira chero dhizaini.
The liquid zvinhu zvinoshandiswaSLA kudhindaanowanzo kunzi "resin" uye ari thermoset polymers. Yakasiyana-siyana resin inowanikwa mune zvekutengesa uye zvakare zvinogoneka kushandisa emumba resins kuyedza akasiyana semuenzaniso.Material zvivakwa zvinosiyana zvichienderana nemagadzirirwo emagadzirirwo: "midziyo inogona kuve yakapfava kana kuoma, yakazadzwa zvakanyanya nezvinhu zvechipiri segirazi neceramic, kana yakazadzwa nemakanika zvinhu senge tembiricha yekupisa kupisa kana kukanganisa kuramba". Munguva ichangopfuura, zvimwe zvidzidzo zvakaedza mukana wezvakasvibira kana zvinogona kushandiswazve kugadzira "zvinogara" resins. Zvinokwanisika kuisa resins muzvikamu zvinotevera:
1- Standard resins, kune general prototyping.
2- Injiniya resins, kune chaiyo mechanic uye inopisa zvivakwa.
3- Mazino uye ekurapa resin, kune biocompatibility certification.
4- Castable resin, ye zero ash-content mushure mekuneta.
5- Biomaterial resins, yakagadzirwa semvura inogadziriswa yemapolymers ekugadzira se polyethylene glycol, kana biological polymers senge gelatin, dextran, kana hyaluronic acid.
SLA 3d kudhinda ndiyo yekutanga yekuwedzera yekugadzira maitiro akabatanidzwa anozivikanwa se "3D kudhinda", anga ari akanyanya kukura uye anoshandiswa zvakanyanya maitiro. kutamba basa rakakosha mukugadzira dhizaini, mazino ekurapa, maindasitiri ekugadzira, animation basa remaoko, dzidzo yekoreji, mamodheru ekuvaka, zvishongo zvezvishongo, kugadzirisa kwemunhu uye mamwe minda.
Kana iwe uchida kuziva rumwe ruzivo uye uchida kugadzira 3d printing modhi, ndapota tauraJSADD 3D Mugadziringuva dzese.
