Mugihe imirimo myinshi yo gukora ikorwa imbere muri printer ya 3D nkibice byubatswe kimwe na layer, ntabwo ari iherezo ryibikorwa. Nyuma yo gutunganya nintambwe yingenzi muri 3D yo gucapa ya 3D yumurimo wanditseho ibice byanditse mubicuruzwa byarangiye. Ni ukuvuga, "Kohereza nyuma" ntabwo ari inzira yihariye, ahubwo ni icyiciro kigizwe nubuhanga butandukanye bwo gutunganya hamwe na tekinike nyinshi zirashobora gukoreshwa kandi zihujwe no kubahiriza ibisabwa bitandukanye nibisabwa.
Nkuko tuzabibona muburyo burambuye muriki kiganiro, hari byinshi byo gutunganya no gutunganya amashuri yo kurangiza, harimo no gutunganya nyuma yo gutunganya (nko gukungana), hejuru yumubiri), no gutunganya amabara. Gusobanukirwa inzira zitandukanye ushobora gukoresha muri 3D Gucapa bizagufasha kuzuza ibisabwa nibisabwa, niba intego yawe ari ukugera hejuru yubuso bwuzuye, cyangwa kongera umusaruro. Reka dusuzume neza.
Inyandiko yibanze isanzwe yerekeza ku ntambwe yambere nyuma yo gukuraho no gusukura igice cya 3D mu gikonoshwa, harimo no gukuraho inkunga hamwe no kwitegura neza (mugutegura uburyo bworoshye bworoshye).
Ibikorwa byinshi bya 3D, harimo kwerekana uburyo bwo kubitsa (FDM), Stereoliwithography (DLS), bisaba gukoresha ibyuma bya synthesing . . Ubusanzwe. Nubwo izi nyubako ni ingirakamaro mubikorwa byo gucapa, bigomba kuvaho mbere yo kurangiza tekinike irashobora gukoreshwa.
Gukuraho inkunga birashobora gukorwa muburyo butandukanye, ariko inzira imwe muri iki gihe irimo akazi k'intoki, nko gukata, gukuraho inkunga. Mugihe ukoresheje resika-gukemurwa mumazi, imiterere yinkunga irashobora gukurwa no kwibiza ikintu cyacapwe mumazi. Hariho kandi ibisubizo byihariye byo gukuraho igice cyikora, cyane cyane icyuma kibazwa Inganda, zikoresha ibikoresho nkimashini za CNC na robo kugirango bagabanye neza inkunga kandi bakomeze kwihanganira.
Ubundi buryo bwibanze bwo gutunganya ni umucanga. Inzira ikubiyemo gutera ibice byacapwe hamwe nigice kirimo igitutu kinini. Ingaruka zibikoresho byibasiwe kumurongo wo gucapa bitera urusaku rworoshye, rumwe.
Umusenyi akenshi nintambwe yambere yononosoye hejuru yubuso bwa 3D yacapwe neza kandi ikuraho neza ibikoresho bisigaye kandi bigatera intambwe imwe noneho yiteguye guhagarara, gushushanya cyangwa gushushanya cyangwa gushushanya. Ni ngombwa kumenya ko umusenyi atarangiza iherezo cyangwa glossy.
Kurenga umusenyi wibanze, hariho ubundi buryo bwo gutunganya nyuma bwo gutunganya bushobora gukoreshwa mugutezimbere neza nuburyo butandukanye bwibiranga ibice byacapwe, nka matte cyangwa isura ya matte cyangwa glossy. Mubihe bimwe na bimwe, kurangiza tekinike birashobora gukoreshwa kugirango ugere kuri ubwo buryo bworoshye mugihe ukoresheje ibikoresho bitandukanye byubaka no gucapa. Ariko, mubindi bihe, hejuru yubusa bikwiranye nubwoko bumwe bwitangazamakuru cyangwa icapiro. Igice cya geometrie hamwe nibikoresho bibiri byingenzi mugihe uhisemo bumwe muburyo bworoshye bworoshye (byose biboneka muri Xometry byihuse).
Ubu buryo nyuma bwo gutunganya burasa numucanga busanzwe mubyo bikubiyemo ibyo bikubiyemo gukoresha ibice kubicapwe munsi yigitutu. Ariko, hariho itandukaniro ryingenzi: Umusenyi ntabwo akoresha ibice byose (nkumucanga), ariko akoresha amasaro yikirahure nkigitugu kuri sandblast icapiro.
Ingaruka zibihumyo byikirahure hejuru yicapiro bitera ingaruka zoroshye kandi zingana. Usibye inyungu zitanga umusenyi, inzira yoroshye yongerera imbaraga zubukanishi ryigice bitabangamiye ubunini bwayo. Ibi ni ukubera ko imiterere yimisatsi yikirahure ishobora kugira ingaruka zidasanzwe hejuru yikigice.
Kwangirika, uzwi kandi ku izina, ni igisubizo cyiza cyo gutunganya ibice bito. Ikoranabuhanga rikubiyemo gushyira 3d icapiro mu ngoma hamwe n'ibice bito bya ceramic, plastiki cyangwa ibyuma. Ingoma noneho izunguruka cyangwa iranyeganyega, itera imyanda isigaburira igice cyanditse, ikuraho ibitari byose bitavugwa no gukora ubuso bwiza.
Kwangirika kw'itangazamakuru birakomeye kuruta umucanga, kandi ubuso bworoshye bushobora guhinduka bitewe n'ubwoko bw'ibikoresho byo gusetsa. Kurugero, urashobora gukoresha itangazamakuru rito kugirango ukore ibara ryuzuye, mugihe ukoresheje chip-grit zirashobora kubyara hejuru. Zimwe muri sisitemu nini yo kurangiza irashobora gukemura ibice gupima 400 x 120 x 120 mm cyangwa 200 x 200 x 200 x 200 x 200 x 200. Rimwe na rimwe, cyane cyane hamwe na MJF cyangwa ibice bya SLS, inteko irashobora guteganwa gake hamwe na utwara.
Mugihe uburyo bwose bworoshye bworoshye bushingiye kumikorere yumubiri, inyamanswa yoroshye yishingikiriza kumyitwarire yimiti hamwe nibikoresho byacapwe hamwe no gukora neza. By'umwihariko, inyamanswa yoroshye ikubiyemo kwerekana 3D icapiro kuri Solven (nka fa 326) mu cyumba gishinzwe gutunganya. Ihuriro ryibice hejuru yicapiro kandi rirema imiti igenzurwa, koroshya ubusembwa ubwo aribwo bwose bwo kudatungana, imisozi n'ibibaya no kugabura ibikoresho byashongeye.
Imyanda inoze kandi izwiho gutanga ubuso bwarangije kandi glossy irangiye. Mubisanzwe, inzira yoroshye yoroshye irahenze kuruta koroshya umubiri, ariko ikundwa kuberako neza no kurangiza neza. Imyuka yoroshye irahuye na polymer nyinshi nibikoresho bya elastomeric 3d.
Amabara nkinyongera yinyongera yo gutunganya nuburyo bwiza bwo kongera imbaraga zumurimo wawe wacapwe. Nubwo ibikoresho bya 3D (cyane cyane filaments) biza muburyo butandukanye bwamabara, kuri nyuma yinyuma igufasha gukoresha ibikoresho nibikorwa byo gucapa byujuje ibisobanuro bifatika kubikoresho byatanzwe. ibicuruzwa. Dore uburyo bubiri busanzwe bwamabara kugirango icapiro rya 3D.
Gushushanya gushushanya nuburyo buzwi burimo gukoresha ibikoresho bya aerosol kugirango ukoreshe igice cya parike kuri 3D icapiro. Mugutera icapiro rya 3D, urashobora gutera gusiga irangi kuruhande, bitwikiriye hejuru. . Ariko, ifite imboga imwe ikomeye: Kubera ko wino ikoreshwa muburyo bunoze, niba igice cyacapwe cyangwa cyambarwa, ibara ryumwimerere ryibikoresho byacapwe bizagaragara. Inzira yo gushushanya ikurikirana iki kibazo.
Bitandukanye no gushushanya cyangwa gukaraba, wino muri 3D icapiro ryinjira munsi yubuso. Ibi bifite ibyiza byinshi. Ubwa mbere, niba icapiro rya 3d riba ryambarwa cyangwa rishushanyije, amabara yacyo azakomeza kuba adafite ishingiro. Izinganuka nayo ntabwo ishaka, niyo irangi rizwiho gukora. Ikindi cyifuzo kinini cyo gusiga irangi nuko kidahindura neza urwego rwicapiro: Kuva irangi ryinjira hejuru yicyitegererezo, ntabwo yongera ubunini bityo ntibikongera gutakaza ibisobanuro. Inzira yihariye yamabara iterwa nigikoresho cya 3D.
Ibikorwa byose byo kurangiza birashoboka mugihe ukorana numufatanyabikorwa ukurikirana nka Xometrie, bikwemerera gukora ibyapa bya 3D byumwuga bihuye nibikorwa nibipimo byiza.
