Mugihe imirimo myinshi yo gukora ikorerwa imbere ya printer ya 3D nkuko ibice byubatswe kumurongo, ntabwo aribyo byanyuma. Nyuma yo gutunganya ni intambwe yingenzi mubikorwa byo gucapa 3D bihindura ibice byacapwe mubicuruzwa byarangiye. Ni ukuvuga, "nyuma yo gutunganya" ubwayo ntabwo ari inzira yihariye, ahubwo ni icyiciro kigizwe nubuhanga nubuhanga butandukanye bwo gutunganya bushobora gukoreshwa no guhuzwa kugirango buhuze ibyifuzo bitandukanye kandi byiza.
Nkuko tuzabibona muburyo burambuye muriyi ngingo, hariho tekinike nyinshi zo gutunganya no gutunganya hejuru yubutaka, harimo ibyingenzi nyuma yo gutunganya (nko gukuraho inkunga), koroshya ubuso (umubiri na chimique), no gutunganya amabara. Gusobanukirwa inzira zitandukanye ushobora gukoresha mugucapisha 3D bizagufasha kubahiriza ibicuruzwa nibisabwa, niba intego yawe ari ukugera kubuziranenge bwubuso bumwe, ubwiza bwihariye, cyangwa kongera umusaruro. Reka turebe neza.
Ibyingenzi nyuma yo gutunganyirizwa mubisanzwe byerekana intambwe yambere nyuma yo gukuraho no gusukura igice cyacapwe cya 3D mugikonoshwa cyinteko, harimo kuvanaho inkunga no korohereza ubuso bwibanze (mugutegura uburyo bunoze bwo koroshya).
Uburyo bwinshi bwo gucapa 3D, harimo kwerekana imiterere yabitswe (FDM), stereolithography (SLA), ibyuma byerekana ibyuma bya laser (DMLS), hamwe na synthesis ya carbone digitale (DLS), bisaba gukoresha ibikoresho byunganira kugirango habeho ibibyimba, ibiraro, nuburyo bworoshye. . . umwihariko. Nubwo izi nyubako ari ingirakamaro mugucapura, zigomba kuvaho mbere yubuhanga bwo kurangiza zishobora gukoreshwa.
Gukuraho inkunga birashobora gukorwa muburyo butandukanye, ariko inzira isanzwe uyumunsi ikubiyemo imirimo yintoki, nko gukata, kugirango ikureho inkunga. Mugihe ukoresheje amazi-elegitoronike yubutaka, imiterere yinkunga irashobora gukurwaho kwibiza mumazi yacapwe mumazi. Hariho kandi ibisubizo byihariye byo kuvanaho ibice byikora, cyane cyane ibyuma byongera ibyuma, bikoresha ibikoresho nkimashini za CNC na robo kugirango bigabanye neza inkunga kandi bikomeze kwihanganira.
Ubundi buryo bwibanze nyuma yo gutunganya ni sandblasting. Inzira ikubiyemo gutera ibice byanditse hamwe nuduce munsi yumuvuduko mwinshi. Ingaruka yibikoresho bya spray hejuru yicyapa ikora ibintu byoroshye, byinshi.
Sandblasting niyo ntambwe yambere yo koroshya ubuso bwa 3D bwacapwe kuko bukuraho neza ibintu bisigaye kandi bigakora ubuso bumwe noneho bukaba bwiteguye gutera intambwe ikurikira nko gusiga, gushushanya cyangwa gusiga irangi. Ni ngombwa kumenya ko gutera umucanga bidatanga urumuri rwiza cyangwa rwiza.
Kurenga umusenyi wibanze, hari ubundi buhanga nyuma yo gutunganya bushobora gukoreshwa mugutezimbere ubwiza nibindi bintu byo hejuru yibice byacapwe, nka matte cyangwa glossy. Rimwe na rimwe, tekinike yo kurangiza irashobora gukoreshwa kugirango ugere ku bworoherane mugihe ukoresheje ibikoresho bitandukanye byubaka hamwe nuburyo bwo gucapa. Ariko, mubindi bihe, koroshya ubuso bikwiranye gusa nubwoko runaka bwitangazamakuru cyangwa icapiro. Igice cya geometrie hamwe nibikoresho byanditse nibintu bibiri byingenzi muguhitamo bumwe muburyo bukurikira bwo koroshya ubuso (byose biboneka muri Xometry Instant Pricing).
Ubu buryo bwo gutunganya ibintu bisa nibitangazamakuru bisanzwe byumusenyi kuko bikubiyemo gushyira uduce duto ku icapiro ryumuvuduko mwinshi. Ariko, hariho itandukaniro ryingenzi: gutera umucanga ntabwo ukoresha ibice byose (nkumucanga), ariko ukoresha amasaro yikirahure yikigereranyo nkuburyo bwo guhuza umucanga icapiro kumuvuduko mwinshi.
Ingaruka zamasaro yikirahure hejuru yubuso butanga ingaruka nziza kandi nziza. Usibye ibyiza byubwiza bwumusenyi, inzira yo korohereza yongerera imbaraga imashini igice kitagize ingaruka kubunini bwayo. Ibi ni ukubera ko imiterere yububiko bwamasaro yikirahure irashobora kugira ingaruka zidasanzwe hejuru yikigice.
Kunyerera, bizwi kandi nko kwerekana, ni igisubizo cyiza nyuma yo gutunganya ibice bito. Ikoranabuhanga ririmo gushyira icapiro rya 3D mu ngoma hamwe nuduce duto twa ceramic, plastike cyangwa ibyuma. Ingoma noneho irazunguruka cyangwa iranyeganyega, itera imyanda kunyerera ku gice cyacapwe, ikuraho ibintu byose bitagenda neza kandi bigakora ubuso bunoze.
Kunyerera mu bitangazamakuru birakomeye kuruta guhanagura umucanga, kandi uburinganire bwubuso burashobora guhinduka bitewe nubwoko bwibikoresho. Kurugero, urashobora gukoresha itangazamakuru ryintete nkeya kugirango ukore uburinganire bwimiterere, mugihe ukoresheje chip-grit chip irashobora gutanga ubuso bworoshye. Zimwe muri sisitemu nini cyane yo kurangiza irashobora gukora ibice bipima 400 x 120 x 120 mm cyangwa 200 x 200 x 200 mm. Rimwe na rimwe, cyane cyane hamwe n'ibice bya MJF cyangwa SLS, inteko irashobora gutemba neza hamwe nuwitwaye.
Mugihe uburyo bwose bwavuzwe haruguru bwo koroshya bushingiye kumikorere yumubiri, koroshya amavuta bishingiye kumiti yimiti hagati yibikoresho byacapwe hamwe na parike kugirango bitange ubuso bunoze. By'umwihariko, koroshya amavuta bikubiyemo kwerekana icapiro rya 3D kumashanyarazi (nka FA 326) mubyumba bitunganyirizwa hamwe. Imyuka ifata hejuru yicyapa kandi igakora imiti igenzurwa, igahindura ubusembwa ubwo aribwo bwose, imisozi n’ibibaya mugusaranganya ibikoresho byashongeshejwe.
Korohereza amavuta bizwi kandi guha ubuso burangije neza kandi burabagirana. Mubisanzwe, uburyo bwo koroshya ibyuka buhenze kuruta koroshya umubiri, ariko bikundwa kubera ubwiza bwabyo burenze kandi burangije. Vapor Smoothing irahuza na polymers nyinshi nibikoresho bya 3D bya elastomeric.
Guhindura amabara nkintambwe yinyongera-gutunganya intambwe ninzira nziza yo kuzamura ubwiza bwibisohoka byacapwe. Nubwo ibikoresho byo gucapa 3D (cyane cyane filaments ya FDM) biza muburyo butandukanye bwamabara, gutondeka nkibikorwa byanyuma bigufasha gukoresha ibikoresho nibikorwa byo gucapa byujuje ibisobanuro byibicuruzwa kandi ukagera kumabara akwiye kubintu runaka. ibicuruzwa. Hano hari uburyo bubiri busanzwe bwo gusiga amabara yo gucapa 3D.
Gusiga amarangi ni uburyo buzwi burimo gukoresha icyuma cya aerosol kugirango ushireho irangi ku icapiro rya 3D. Muguhagarika icapiro rya 3D, urashobora gutera irangi kuringaniza igice, utwikiriye ubuso bwacyo bwose. . Nyamara, ifite imbogamizi imwe yingenzi: kuva wino ikoreshwa muburyo bworoshye, niba igice cyacapwe cyashushanijwe cyangwa cyambarwa, ibara ryumwimerere ryibikoresho byacapwe bizagaragara. Igicucu gikurikira gikemura iki kibazo.
Bitandukanye no gusiga irangi cyangwa gukaraba, wino yo gucapa 3D yinjira munsi yubutaka. Ibi bifite ibyiza byinshi. Ubwa mbere, niba icapiro rya 3D rimaze kwambarwa cyangwa gushushanya, amabara yaryo meza azakomeza kuba ntamakemwa. Ikirangantego nacyo ntigikuramo, nicyo kizwiho gukora. Iyindi nyungu nini yo gusiga irangi ni uko itagira ingaruka ku bipimo bifatika byerekana: kuva irangi ryinjira hejuru yicyitegererezo, ntabwo ryongera umubyimba bityo ntirishobora gutakaza ibisobanuro birambuye. Uburyo bwihariye bwo gusiga amabara biterwa nuburyo bwo gucapa 3D nibikoresho.
Izi nzira zose zo kurangiza zirashoboka mugihe ukorana nabafatanyabikorwa bakora nka Xometry, bikwemerera gukora printer ya 3D yabigize umwuga yujuje imikorere nuburinganire bwiza.
