Nepo mazhinji emabasa ekugadzira achiitwa mukati meiyo 3D printa sezvo zvikamu zvakavakwa dhizaini ne layer, handiko kupera kwemaitiro. Post-processing inhanho yakakosha mu 3D yekudhinda mafambiro inoshandura zvikamu zvakadhindwa kuita zvigadzirwa zvakapedzwa. Ndokureva kuti, "post-processing" pachayo haisi nzira chaiyo, asi chikamu chinosanganisira akawanda akasiyana maitiro ekugadzirisa uye matekiniki anogona kushandiswa nekubatanidzwa kuti asangane nekunaka uye kushanda zvinodiwa.
Sezvatichaona zvakadzama munyaya ino, kune akawanda post-processing and surface finishing techniques, anosanganisira basic post-processing (sekubvisa tsigiro), kutsetseka kwepamusoro (pamuviri nekemikari), uye kugadzirwa kwemavara. Kunzwisisa maitiro akasiyana aunogona kushandisa mukudhinda kwe 3D kuchakubvumidza kuti usangane nezvido zvechigadzirwa uye zvinodiwa, ingave chinangwa chako chiri chekuwana yunifomu yemhando yepamusoro, chaiyo aesthetics, kana kuwedzera kubereka. Ngatinyatsoongororai.
Basic post-processing kazhinji inoreva matanho ekutanga mushure mekubvisa uye kuchenesa iyo 3D yakadhindwa chikamu kubva mugoko regungano, kusanganisira kubviswa kwerutsigiro uye kutsetseka kwepasi (mukugadzirira mamwe maitiro ekutsvedzerera).
Mazhinji 3D ekudhinda maitiro, anosanganisira fused deposition modeling (FDM), stereolithography (SLA), direct metal laser sintering (DMLS), uye carbon digital light synthesis (DLS), inoda kushandiswa kwezvimiro zvekutsigira kugadzira protrusion, mabhiriji, uye zvimiro zvisina kusimba. . . peculiarity. Kunyange zvazvo zvivakwa izvi zvinobatsira pakudhinda, zvinofanira kubviswa nzira dzokupedzisa dzisati dzashandiswa.
Kubvisa kutsigirwa kunogona kuitwa nenzira dzakasiyana-siyana, asi nzira yakajairika nhasi inosanganisira basa remaoko, sekucheka, kubvisa rubatsiro. Paunenge uchishandisa mvura-soluble substrates, chimiro chekutsigira chinogona kubviswa nekunyudza chinhu chakadhindwa mumvura. Kune zvakare magadzirirwo akasarudzika ekubvisa otomatiki chikamu, kunyanya simbi yekuwedzera kugadzirwa, iyo inoshandisa maturusi senge CNC michina uye marobhoti kucheka nemazvo zvinotsigira uye kuchengetedza kushivirira.
Imwe nzira yakakosha mushure mekugadzirisa ndeye sandblasting. Iyo nzira inosanganisira kupfapfaidza zvikamu zvakadhindwa nezvimedu zviri pasi pekumanikidzwa kukuru. Mhedzisiro yemidziyo yekupfapfaidza pane yakadhindwa pamusoro inogadzira yakapfava, yakawedzera yunifomu kugadzirwa.
Sandblasting inowanzoita nhanho yekutanga mukutsvedzerera 3D yakadhindwa pamusoro sezvo ichinyatso bvisa zvisaririra uye kugadzira imwe yunifomu yepamusoro iyo inobva yagadzirira matanho anotevera akadai sekukwenenzvera, kupenda kana kusvibisa. Zvakakosha kuziva kuti kuputika kwejecha hakubudisi kupera kupenya kana kupenya.
Beyond basic sandblasting, kune dzimwe post-processing matekiniki anogona kushandiswa kuvandudza kutsvedzerera uye zvimwe zvinhu zvepamusoro zvezvakadhindwa, senge matte kana kupenya. Mune zvimwe zviitiko, maitiro ekupedzisa anogona kushandiswa kuwana hunyoro kana uchishandisa zvakasiyana siyana zvekuvaka uye kudhinda maitiro. Nekudaro, mune zvimwe zviitiko, kutsetseka kwepamusoro kunokodzera chete kune mamwe marudzi enhau kana maprints. Chikamu geometry uye zvinyorwa zvekudhinda ndizvo zviviri zvakakosha zvinhu pakusarudza imwe yeinotevera nzira yekutsvedzerera pamusoro (ese aripo muXometry Instant Pricing).
Iyi post-processing nzira yakafanana neyakajairwa midhiya sandblasting pakuti inosanganisira kushandisa zvimedu kudhinda pasi pekumanikidzwa kwakanyanya. Zvisinei, pane musiyano unokosha: jecha harishandisi chero zvimedu (sejecha), asi rinoshandisa spherical girazi beads sepakati nejecha rinodhinda nekumhanya kukuru.
Iko kukanganiswa kwemagirazi egirazi mabhedhi pamusoro peiyo kudhinda kunogadzira yakatsetseka uye yakawanda yakafanana pamusoro pekuita. Kuwedzera kune aesthetic mabhenefiti ejecha blasting, iyo inotsvedza nzira inowedzera simba remagetsi rechikamu pasina kukanganisa saizi yayo. Izvi zvinodaro nekuti chimiro che spherical chegirazi bead chinogona kuve nepamusoro pepamusoro pepamusoro pechikamu.
Kudonha, kunozivikanwawo sekutarisa, mhinduro inoshanda yemashure-kugadzirisa zvikamu zvidiki. Iyo tekinoroji inosanganisira kuisa 3D kudhindwa mudhiramu pamwe nezvidimbu zvidiki zveceramic, plastiki kana simbi. Ngoma yacho inobva yatenderera kana kuzunguzika, zvichiita kuti marara akweshe pachikamu chakadhindwa, obvisa chero kusarongeka kwechiso uye kugadzira nzvimbo yakatsetseka.
Media tumbling ine simba kudarika sandblasting, uye kutsetseka kwepamusoro kunogona kugadziriswa zvichienderana nerudzi rwezvinhu zvinodonha. Semuenzaniso, iwe unogona kushandisa yakaderera-zviyo midhiya kugadzira rougher pamusoro pekugadzirwa, nepo kushandisa yakakwirira-grit machipisi inogona kuburitsa nzvimbo yakatsetseka. Mamwe emagadzirirwo makuru ekupedzisa anogona kubata zvikamu zvinoyera 400 x 120 x 120 mm kana 200 x 200 x 200 mm. Mune zvimwe zviitiko, kunyanya neMJF kana SLS zvikamu, gungano rinogona kudonha rakakwenenzverwa nemutakuri.
Nepo ese ari pamusoro apa nzira dzekutsvedzerera dzakavakirwa pamaitiro emuviri, kutsvedza kweutsi kunovimba nekuita kwekemikari pakati pezvakadhindwa uye mhepo kuti ibudise nzvimbo yakatsetseka. Kunyanya, kutsvedzerera kweutsi kunosanganisira kufumura iyo 3D inodhinda kune inoputika solvent (senge FA 326) mukamuri yakavharwa yekugadzirisa. Iyo mutsi inonamatira pamusoro pekudhinda uye inogadzira inodzorwa kemikari inonyunguduka, inotsvedzerera kunze kusakwana kwepamusoro, mirwi nemipata nekugoverazve zvinhu zvakanyungudutswa.
Steam kutsvedzerera kunozivikanwa zvakare kupa pamusoro pekuwedzera kukwenenzverwa uye kupenya kupera. Kazhinji, iyo steam smoothing process inodhura pane kutsvedzerera kwemuviri, asi inofarirwa nekuda kwekutsetseka kwayo uye kupera kupenya. Vapor Smoothing inoenderana nemapolymer mazhinji uye elastomeric 3D kudhinda zvinhu.
Kupenda seimwe yekuwedzera post-kugadzirisa nhanho inzira huru yekusimudzira aesthetics yezvakadhindwa zvabuda. Kunyange zvazvo 3D zvinyorwa zvekudhinda (kunyanya FDM filaments) zvinouya mune zvakasiyana-siyana zvemavara ekusarudza, toning se post-process inokubvumira kushandisa zvinhu uye maitiro ekudhinda anosangana nezvinodiwa zvechigadzirwa uye kuwana iyo chaiyo yemavara match yechinhu chakapihwa. chigadzirwa. Heano maitiro maviri akajairika ekupenda e3D kudhinda.
Kupfapfaidza pendi inzira yakakurumbira inosanganisira kushandisa aerosol sprayer kuisa layer yependi kune 3D kudhindwa. Nekumbomira 3D kudhinda, unogona kupfapfaidza pendi zvakaenzana pamusoro pechikamu, ichivhara nzvimbo yayo yese. (Paint inogonawo kushandiswa zvakasarudzwa uchishandisa masiki ekugadzira.) Iyi nzira yakajairika kune ese ari maviri 3D akadhindwa uye akagadzirwa zvikamu uye haina kudhura. Zvisinei, ine chimwe chikuru chinokanganisa: sezvo inki inoshandiswa zvakanyanya, kana chikamu chakadhindwa chikakwenywa kana kupfekwa, ruvara rwepakutanga rwezvakadhindwa ruchaonekwa. Iyi inotevera shading process inogadzirisa dambudziko iri.
Kusiyana nekupfapfaidza pendi kana kubhurasha, iyo inki mu 3D kudhinda inopinda pasi pepamusoro. Izvi zvine zvakawanda zvazvakanakira. Chekutanga, kana iyo 3D print ikasakara kana kukweshwa, mavara ayo anopenya acharamba akamira. Tsvina zvakare haibvi, zvinova izvo zvinozivikanwa kuita pendi. Imwe bhenefiti yakakura yekudhaya ndeyekuti haina kukanganisa kurongeka kweiyo kudhinda: sezvo dhayi ichipinda pamusoro peiyo modhi, haina kuwedzera ukobvu uye saka haikonzeri kurasikirwa kweruzivo. Iyo chaiyo yemavara maitiro zvinoenderana neiyo 3D yekudhinda maitiro uye zvinhu.
Ese aya maitiro ekupedzisa anogoneka kana uchishanda nemumwe wekugadzira senge Xometry, ichikubvumidza iwe kuti ugadzire nyanzvi 3D maprints anosangana nekuita uye aesthetics zviyero.
