- Umehluko oyisisekelo phakathi kwe-FDM kanye nobuchwepheshe be-resin kuye ngengxenye ezokhiqizwa.
- Izinto ezinconywayo ezifana ne-PLA, i-PETG, kanye ne-ABS ukuqinisekisa ukuqina kwehadiwe.
- Inqubo yokuklama i-CAD kanye nokucubungula ngemuva kokufeza ukuqedwa kobungcweti nokuhlelekile.
- Izinketho zokwandisa kusukela kuma-prototypes asekhaya kuya ekukhiqizweni kwe-CNC yezimboni.
Uma ungumuntu onganelisekile ngalokho okuthengiswa ezitolo futhi ofuna indawo yakho yokusebenza ibe nokuthinta okuhlukile, ukungena ezweni lokuphrinta kwe-3D ngamakhibhodi omshini kuyindlela eyodwa. Akusadingeki wamukele ukwakheka okujwayelekile kwefektri; manje usungakha yonke into kusukela ekhasethini elifanela ukuma kwezandla zakho kuya ezinkinobho ezinezimo ezihlanyayo eziveza ubuntu bakho.
Ingxenye engcono kakhulu ukuthi lobu buchwepheshe bukuvumela ukuthi uzame ngokugcwele ngaphandle kokuchitha imali eningi. Ungazama ama-engeli ahlukene, udlale nge-acoustics yekhibhodi, noma uklame i- macropad eyenziwe ngokwezifiso ngokuphelele , ulungise yonke imininingwane kuze kube yilapho umuzwa nomsindo kufana ncamashi nalokho obukucabanga ngaphambi kokungena ekukhiqizeni okungathi sína.
Kungani uqala ukwenza ikhibhodi yakho ibe ngokwezifiso nge-3D?
Inzuzo enkulu inkululeko yokudala. Nakuba amakhibhodi ezentengiselwano eqinile ekwakhiweni kwawo, ukukhiqizwa kwezengezo kukuvumela ukuthi udale imiklamo ye-ergonomic noma amakhibhodi ahlukene asiza ukuvimbela ukulimala nokuthuthukisa ukuma. Ngaphezu kwalokho, kuyindlela esheshayo yokwenza i-prototype; uma ingxenye ingahlangabezani nokulindelekile kwakho, umane ushintshe ifayela bese uliphrinta kabusha.
Ngokombono wobuhle, amathuba awapheli. Kusukela ezikhwameni ezinamafasitela aseceleni ukukhombisa ukukhanya kwe-RGB kuya emininingwaneni yomkhiqizo ehlanganiswe ne-geometry yento ngokwayo. Kuyibhuloho elifanele labo abafuna ukusuka emcabangweni wedijithali baye entweni ebonakalayo engeyinhle nje kuphela kodwa futhi esebenza ngokugcwele.
Ubuchwepheshe: I-Resin noma i-Filament (FDM)?
Kuye ngokuthi iyiphi ingxenye yekhibhodi ofuna ukuyikhiqiza, uzodinga umshini ohlukile. Ukuphrinta kwe-FDM , okuvame kakhulu futhi okusebenzisa imiqulu yepulasitiki, kungcono kakhulu ezingxenyeni ezinkulu. Kulungele isakhiwo sangaphandle, isisekelo, kanye nebhodi lesekethe langaphakathi, njengoba kuyonga futhi izinto zokwakha zihlala isikhathi eside kakhulu.
Ngakolunye uhlangothi, uma ufuna ukuphrinta izinkinobho ezinemininingwane emincane noma amalogo amahle kakhulu, ukuphrinta kwe-resin (i-SLA/MSLA) kuyindlela ephumelelayo. Le ndlela inikeza ubuso obubushelelezi nokunemba okumangalisayo, okukuvumela ukuthi udale izinkinobho ezenziwe ngezandla ezibukeka zenziwe efektri, yize zidinga inqubo yokuhlanza nokulungisa enzima kakhulu.
Izinto ezinconyiwe zomphumela ohlala njalo
Akuwona wonke amapulasitiki afanelekela injongo efanayo. I-PLA iyindlela elula neqinile kakhulu, ilungele amakesi angeke ashukunyiswe kakhulu, yize kufanele uqaphele ngokushisa okukhulu njengoba kungagoba.
- I-PETG: Njengoba ilinganisela kahle, imelana kakhulu nokushaqeka futhi inokuguquguquka okuncane okuvimbela isivalo ukuthi singaqhekeki.
- I-ABS ne-ASA: Lezi yizinto zokwakha eziphezulu uma uzifuna ukuzinza kokushisa nokuqina, okwenza zibe zilungele amakhibhodi athuthwa kakhulu.
- Inayiloni nePolycarbonate: Izintambo eziklanywe ngendlela yobunjiniyela zalabo abafuna amandla ezimbonini ezingxenyeni zabo.
Kusukela kumklamo we-CAD kuya kuphrinta
Ukuqinisekisa ukuthi konke kuhambisana kahle okokuqala, ukumodela okunembile kubalulekile. Okungcono kakhulu, sebenzisa ukwakheka kwe-PCB kanye namaswishi njengereferensi bese wakha indawo ebiyelwe ezungeze wona , uqiniseke ukuthi ama-port e-USB kanye nama-surge protectors anezicucu eziqondile. Ungakhohlwa ukwengeza ama-chamfers kanye nama-ribs ukuqinisa isakhiwo.
Uma usunayo imodeli, isofthiwe yokusika yilapho umlingo uvela khona. Kuma-FDM cases, kunconywa ukuphakama kwesendlalelo esingu-0.16 kuya ku-0.2 mm kanye nokugcwalisa okuphakathi kuka-20% no-40%. Kubalulekile ukuqondisa izingxenye ukuze izindawo ezibonakala kakhulu zibheke phezulu nokuthi izimbobo zezikulufo zihambisane nokumelana kwentambo.
Ukuthinta kokugcina: Ngemuva kokucubungula nokuhlanganisa
Uma ufuna ikhibhodi yakho ibukeke ingaphezu kwephrojekthi yesikole, ukucubungula ngemuva kubalulekile. Ukuhlikihla imigqa yesendlalelo, ukusebenzisa i-filler primer, bese upenda ngemibala eqinile kungenza ipulasitiki ibukeke njengomshini wokufaka umjovo wobungcweti . Ukuze uvimbele izikulufo ukuthi zingakhumuki ngokuhamba kwesikhathi, kungcono ukufaka izifakelo zensimbi ezifakwe intambo usebenzisa ukushisa.
Ngesikhathi sokuhlanganiswa, indlela ewusizo kakhulu ukufaka kuqala ama-stabilizer nama-switch ebhodini bese ufaka yonke i-assembly ebhokisini. Uma ivaliwe, ungalungiselela i-firmware usebenzisa amathuluzi afana ne -QMK noma i-VIA ukwenza okhiye benze lokho okufunayo futhi udale imiphumela emihle yokukhanya.
Ukulungisa kahle umsindo nomuzwa
Enye yezingxenye ezijabulisa kakhulu ukuhleleka kwe-acoustic. Izinto zekhava kanye nobukhulu bodonga kushintsha ngokuphelele umsindo wekhibhodi. Ukuze kuvinjwe ukuthi ingezwakali "njengebhokisi elingenalutho," abathandi abaningi bafaka amashidi e-foam noma e-silicone ngaphakathi kwekhava eliphrintiwe.
Ungazama ukugcwalisa okuhlukene noma usebenzise ama-gasket okufaka phakathi kwepuleti nebhokisi ukuze uthole umuzwa wokubhala obushelelezi kanye nomsindo othambile nowanelisayo, owaziwa emphakathini njengomsindo "onzima".
Uma iphrojekthi ikhula: Kusukela ku-3D kuya ku-CNC
Kufika isikhathi lapho ukuphrinta kwe-3D kungaphumeleli khona, ikakhulukazi uma uhlela ukuthengisa imiklamo yakho. Ukuze uthole ukukhiqizwa okukhulu noma ukuqedwa okuphezulu, ikhambi elifanele ukuthuthela ekusetshenzisweni kwe-CNC nge-aluminium noma ukubumba nge-injection. Amafayela osuvele uwalungisile ku-3D asebenza njengesisekelo esiphelele salezi zinqubo zezimboni.
Ukusebenzisana nezimboni ze-OEM kuvumela ukwandisa umkhiqizo ngaphandle kokulahlekelwa umongo womklamo wokuqala, kusuka kumodeli owenziwe ekhaya kuya kumkhiqizo olungele imakethe yomhlaba wonke onezindinganiso zekhwalithi yobungcweti kanye nezinto zensimbi ezisezingeni eliphezulu.
Ikhono lokudala ihadiwe eyenziwe ngokwezifiso ngokugcwele liye lahlukanisa umklamo ongaphandle, okuvumela noma ubani onephrinta ukuthi athuthukise i-ergonomics kanye nobuhle bayo. Kusukela ekukhethweni kwe-filament kuya ekulungisweni komsindo kokugcina kanye nokwenzeka kokukhulisa umkhiqizo kuye ezingeni lezimboni, indlela yokwakha ikhibhodi eyingqayizivele iwukuhlanganiswa kobuciko, ubunjiniyela, kanye nokuhlolwa okubanzi.
