Kune mhando ina huru dzemaitiro e3D kudhinda, uye maitiro matsva anowanzobuda.Imwe neimwe yekuwedzera yekugadzira maitiro inoshandisa akasiyana zvinhu kugadzira zvikamu zvine akasiyana zvivakwa zvinoshanda nemazvo kune chaiwo maapplication.
1. pane photopolymerization
Kuderedza polymerization yemvura photopolymers inorapwa nephotosensitive polymerization ndiyo imwe yekutanga yekuwedzera yekugadzira maitiro.Yakanyatso uv layer ne layer kurapa uye kuomeswa kwematete akaturikidzana e photosensitive resins.Iyi nzira, inozivikanwa sestereophotography, yakatengeswa pakati pemakore ekuma1980.Nepakutanga3D kudhindatekinoroji mupfungwa, stereolithography zvikamu zvinoshandiswa kuisa mari mumashandisirwo akadai sekukanda mapatani, prototypes uye pfungwa modhi.Imwe tekinoroji inocherekedza ndeye digital light processing.
2. zvinhu extrusion
Iyi yekuwedzera yekugadzira mhando inogovera zvinhu nekupisa muromo kana kuburitsa musoro.Mushure mekuisa imwe layer, dzika kuti uvake chikuva, kana kufambisa musoro weextrusion kumusoro kuti udhinde rinotevera layer pamusoro peyapfuura.Iyo mbishi inowanzova thermoplastic filament, yakakuvadzwa pa spool uye yakanyungudutswa kana yaburitswa.Nzira yakajairika kushandisa nzira iyi ndeyekunyungudutswa kwekuisa.Mhando iyi yekuwedzera yekugadzira inogona kushandiswa kugadzira zvikamu, maturusi ekugadzira, uye anoshanda prototypes nekuda kwekugona kuvaka nezvinhu zvakajairika thermoplastic.
3. poda layer fusion
Powder layer fusion nzvimbo yemuchinjikwa yehupfu yakasanganiswa nesimba rekupisa.Kupisa kunonyungudutsa hupfu uye hunoomesa kana hwatonhora.Nemapolymers, hupfu husina kushandiswa hwakatenderedza chikamu hunoshandiswa kubata chikamu panzvimbo, saka hapana imwe tsigiro inowanzodiwa.Kune zvikamu zvesimbi, anchors anowanzodiwa kuti abatanidze zvikamu kumubhedha wekudhinda uye kutsigira kudzika kwekugadzirisa.Laser sintering yakatengeswa muna 1992, ichiteverwa nekumhanya-mhanya sintering uye, nguva pfupi yadarika, multi-jet fusion.Mukugadzira simbi, yakananga simbi laser sintering uye erekitironi danda kunyunguduka kuumba (EBM) anonyanya kufarirwa maindasitiri masisitimu.
4. Kupfapfaidza zvinhu
Material jekiseni ndeimwe yeanokurumidza yekuwedzera nzira dzekugadzira uchishandisa akawanda-nozzle anodhinda misoro.Kuwedzera kugadzira kunoisa madonhwe ezvivakwa zvekuvaka layer by layer.Material jekiseni system inogona kudhinda akawanda-material uye graded zvinhu zvikamu.Zvikamu zvinogadzirwa muzvikamu zvakasiyana zvechinhu chimwe nechimwe, zvichikonzera mavara akasiyana-siyana uye zvinhu zvakasiyana-siyana zvezvinhu.Kazhinji, masisitimu aya anoshandisa photopolymers, waxes uye zvigadzirwa zvedhijitari umo maphotopolymers akawanda anosanganiswa uye akapfapfaidzwa panguva imwe chete.Matekinoroji akadai seakawanda-jet modhi uye jetting anoshandiswa kugadzira nekukurumidza prototyping, pfungwa modhi, maitirwo ekudyara ekudyara, uye anatomical realistic yekurapa mhando.
