Ngakhale kuti ntchito zambiri zopanga zimapangidwa mkati mwa chosindikizira cha 3D monga zigawo zimamangidwa mosanjikiza ndi wosanjikiza, sikumapeto kwa ntchitoyi. Kukonza pambuyo ndi gawo lofunikira mumayendedwe osindikizira a 3D omwe amasintha zida zosindikizidwa kukhala zomalizidwa. Ndiko kuti, "post-processing" palokha si njira yeniyeni, koma gulu lomwe lili ndi njira zambiri zogwirira ntchito ndi njira zomwe zingagwiritsidwe ntchito ndikuphatikizidwa kuti zikwaniritse zofunikira zosiyanasiyana zokongoletsa ndi ntchito.

Monga momwe tidzaonera mwatsatanetsatane m'nkhaniyi, pali njira zambiri zogwirira ntchito komanso zomaliza pamwamba, kuphatikizapo zoyambira pambuyo pokonza (monga kuchotsa chithandizo), kusalaza pamwamba (kuthupi ndi mankhwala), ndi kukonza mitundu. Kumvetsetsa njira zosiyanasiyana zomwe mungagwiritse ntchito pakusindikiza kwa 3D kumakupatsani mwayi wokwaniritsa zomwe mukufuna komanso zomwe mukufuna, kaya cholinga chanu ndikukwaniritsa mawonekedwe amtundu wofanana, kukongola kwapadera, kapena kuchuluka kwa zokolola. Tiyeni tione bwinobwino.

Basic post-processing nthawi zambiri imatanthawuza masitepe oyamba pambuyo pochotsa ndi kuyeretsa gawo losindikizidwa la 3D mu chipolopolo chamsonkhano, kuphatikiza kuchotsa kuthandizira ndi kusalaza koyambira (pokonzekera njira zosalala bwino).

Njira zambiri zosindikizira za 3D, kuphatikiza ma fused deposition modelling (FDM), stereolithography (SLA), direct metal laser sintering (DMLS), ndi carbon digital light synthesis (DLS), zimafuna kugwiritsa ntchito zida zothandizira kupanga ma protrusion, milatho, ndi zomangira zosalimba. . . mwapadera. Ngakhale kuti mapangidwewa ndi othandiza posindikiza, ayenera kuchotsedwa asanamalize njira zomaliza.

Kuchotsa chithandizo kungathe kuchitidwa m'njira zosiyanasiyana, koma njira yodziwika kwambiri masiku ano imaphatikizapo ntchito zamanja, monga kudula, kuchotsa chithandizo. Pogwiritsa ntchito magawo osungunuka m'madzi, dongosolo lothandizira likhoza kuchotsedwa mwa kumiza chinthu chosindikizidwa m'madzi. Palinso njira zapadera zochotsera magawo, makamaka zopangira zitsulo, zomwe zimagwiritsa ntchito zida monga makina a CNC ndi maloboti kuti athe kudula molondola zothandizira ndikusunga kulolerana.

Njira ina yoyambira pambuyo pokonza ndi sandblasting. Njirayi imaphatikizapo kupopera mbewu mankhwalawa ndi tinthu tating'onoting'ono tambiri. Zotsatira za zinthu zopopera pazitsulo zosindikizira zimapanga mawonekedwe osalala, ofanana.

Kuwombera mchenga nthawi zambiri kumakhala gawo loyamba pakusalaza chosindikizidwa cha 3D chifukwa chimachotsa bwino zinthu zotsalira ndikupanga malo ofananirako omwe amakhala okonzekera masitepe otsatirawa monga kupukuta, kupenta kapena kudetsa. Ndikofunika kuzindikira kuti kuphulika kwa mchenga sikutulutsa mapeto owala kapena onyezimira.

Kupitilira kuphulika kwa mchenga, palinso njira zina zomwe zingagwiritsidwe ntchito kuwongolera kusalala ndi zinthu zina zapamwamba pazigawo zosindikizidwa, monga mawonekedwe a matte kapena onyezimira. Nthawi zina, njira zomaliza zingagwiritsidwe ntchito kuti zitheke bwino pogwiritsira ntchito zipangizo zosiyanasiyana zomangira ndi njira zosindikizira. Komabe, nthawi zina, kuwongola pamwamba kumakhala koyenera pamitundu ina ya media kapena prints. Gawo la geometry ndi zosindikizira ndi zinthu ziwiri zofunika kwambiri posankha imodzi mwa njira zotsatirazi zosalaza pamwamba (zonse zikupezeka pamtengo wa Xometry Instant).

Izi positi-processing njira ndi ofanana ndi ochiritsira TV sandblasting kuti kumaphatikizapo kugwiritsa ntchito particles kuti kusindikiza pansi kwambiri. Komabe, pali kusiyana kofunikira: kuphulika kwa mchenga sikumagwiritsa ntchito tinthu tating'onoting'ono (monga mchenga), koma kumagwiritsa ntchito mikanda yagalasi yozungulira ngati sing'anga mpaka sandblast kusindikiza pa liwiro lalikulu.

Zotsatira za mikanda yagalasi yozungulira pamwamba pa kusindikiza kumapanga mawonekedwe osalala komanso ofanana kwambiri. Kuphatikiza pa zabwino zokongoletsa za sandblasting, kusalaza kumawonjezera mphamvu zamakina za gawolo popanda kukhudza kukula kwake. Izi zili choncho chifukwa mawonekedwe ozungulira a mikanda yagalasi amatha kukhala ndi zotsatira zapamwamba kwambiri pamwamba pa gawolo.

Tumbling, yomwe imadziwikanso kuti screening, ndi njira yabwino yothetsera magawo ang'onoang'ono pambuyo pokonza. Ukadaulo umaphatikizapo kuyika chosindikizira cha 3D mu ng'oma pamodzi ndi tinthu tating'ono ta ceramic, pulasitiki kapena chitsulo. Ng’omayo imazungulira kapena kunjenjemera, zomwe zimapangitsa kuti zinyalala zifike pagawo losindikizidwa, kuchotsa zolakwika zilizonse zapamtunda ndikupanga malo osalala.

Media tumbling ndi yamphamvu kwambiri kuposa sandblasting, ndipo kusalala kwa pamwamba kumatha kusinthidwa kutengera mtundu wa zinthu zopunthwa. Mwachitsanzo, mutha kugwiritsa ntchito zofalitsa zotsika kwambiri kuti mupange mawonekedwe owoneka bwino, pomwe kugwiritsa ntchito tchipisi tating'onoting'ono kumatha kupanga malo osalala. Zina mwazinthu zazikulu zomaliza zomaliza zimatha kugwira zigawo zoyezera 400 x 120 x 120 mm kapena 200 x 200 x 200 mm. Nthawi zina, makamaka ndi magawo a MJF kapena SLS, gululo limatha kupukutidwa ndi chonyamulira.

Ngakhale kuti njira zonse zomwe zili pamwambazi zimachokera kuzinthu zakuthupi, kutsekemera kwa nthunzi kumadalira momwe mankhwala amachitira pakati pa zinthu zosindikizidwa ndi nthunzi kuti apange pamwamba. Makamaka, kusalaza kwa nthunzi kumaphatikizapo kuulula chosindikizira cha 3D ku chosungunulira chotuluka nthunzi (monga FA 326) muchipinda chomata chosindikizira. Nthunzi imamatira pamwamba pa kusindikiza ndikupanga kusungunuka kwa mankhwala olamulidwa, kuwongolera zolakwika zilizonse zapamtunda, zitunda ndi zigwa pogawanso zinthu zosungunuka.

Kusalaza kwa nthunzi kumadziwikanso kuti kumapangitsa kuti pamwamba pakhale opukutidwa komanso onyezimira. Nthawi zambiri, kusalaza kwa nthunzi kumakhala kokwera mtengo kuposa kusalaza kwakuthupi, koma kumakondedwa chifukwa cha kusalala kwake komanso kutha kwake konyezimira. Vapor Smoothing imagwirizana ndi ma polima ambiri komanso zida zosindikizira za 3D za elastomeric.

Kupaka utoto ngati gawo lowonjezera pambuyo pokonza ndi njira yabwino yolimbikitsira kukongola kwa zomwe mwasindikiza. Ngakhale zida zosindikizira za 3D (makamaka FDM filaments) zimabwera m'njira zosiyanasiyana zamitundu, toning ngati post-process imakupatsani mwayi wogwiritsa ntchito zida ndi njira zosindikizira zomwe zimakwaniritsa zofunikira zazinthu ndikukwaniritsa mtundu woyenera wazinthu zomwe zaperekedwa. mankhwala. Nazi njira ziwiri zojambulira zodziwika bwino zosindikizira za 3D.

Kupaka utoto ndi njira yotchuka yomwe imaphatikizapo kugwiritsa ntchito chopopera cha aerosol kuti mugwiritse ntchito utoto wosanjikiza pazithunzi za 3D. Poyimitsa kaye kusindikiza kwa 3D, mutha kupopera utoto wofanana pagawolo, ndikuphimba gawo lonselo. (Utoto ungagwiritsidwenso ntchito posankha pogwiritsa ntchito njira zophimba nkhope.) Njirayi ndiyofala pazigawo zonse za 3D zosindikizidwa ndi makina ndipo ndi yotsika mtengo. Komabe, ili ndi vuto limodzi lalikulu: popeza inki imayikidwa mochepa kwambiri, ngati gawo losindikizidwa likuphwanyidwa kapena kuvala, mtundu woyambirira wa zinthu zosindikizidwa udzawonekera. Njira yotsatira ya shading imathetsa vutoli.

Mosiyana ndi utoto wopopera kapena kutsuka, inki mu kusindikiza kwa 3D imalowa pansi. Izi zili ndi ubwino wambiri. Choyamba, ngati chosindikizira cha 3D chitha kuvala kapena kukanda, mitundu yake yowoneka bwino ikhalabe. Tsitsilinso silimachoka, zomwe ndizomwe utoto umadziwika kuti umachita. Ubwino wina waukulu wa utoto ndikuti sizimakhudza kulondola kwa mawonekedwe a kusindikiza: popeza utoto umadutsa pamwamba pa fanizolo, suwonjezera makulidwe ndipo chifukwa chake sichimayambitsa kutayika kwatsatanetsatane. Kukongoletsa kwapadera kumadalira njira yosindikizira ya 3D ndi zipangizo.

Njira zonse zomalizazi ndizotheka mukamagwira ntchito ndi mnzake wopanga ngati Xometry, kukulolani kuti mupange zojambula zaukadaulo za 3D zomwe zimakwaniritsa magwiridwe antchito komanso kukongola.
