Amathiphu namasu wokususa izinto zokusekela kusuka ezintweni zakho eziphrintiwe ze-3D
Ukuthembela kungenza uwele phansi. Umthetho osobala ocacile we-physics, kodwa uma uqala ukusebenza ne-3D printer, awucabangi ngakho ngaso sonke isikhathi. Kuze kube yilapho uzama ukunyathelisa okuthile nge-overhang noma ingxenye ephikisayo, tshela ingalo eyeluliwe noma ibhola lesikhwama esikhulu, noma mhlawumbe ibanga elifana nebhuloho phakathi kwamaphoyinti amabili. Khona-ke uthola kabusha imithetho ye-physics ne-gravity.
Ukuphrinta kwe-3D kuzodinga ukuthi yini eyaziwa ngokuthi yisekelo. Noma iyiphi into ene-overhang noma yini enye ngaphandle kwefomu eliyisisekelo (cabanga ngesilinda, ukuvimba, into enhle kakhulu, njll) idinga isici sokusekela ukuze singagweli, sagging, noma ukuqubuka kwisendlalelo sangaphambilini.
Ku-Tweaking and Slicing for Better 3D Prints, u-Sherri Johnson, we-CatzPaw Innovations, inkampani edizayinisa ne-3D prints model model izesekeli ezisetshenziselwa ezakhiweni ze-Model Railroad, ichaza indlela yokwengeza isekela ngesandla ohlelweni lwe-CAD uma imodeli yakhelwe, noma ngokusebenzisa lokho akubiza ngokuthi isigaba sokulungisa nesofthiwe ekhethekile, noma esigabeni sokunyathelisa usebenzisa isofthiwe yokuhlunga.
Kulokhu okuthunyelwe, ngifuna ukuhlola indlela olahla ngayo yonke leyo support. Njengoba ubona esithombeni esingenhla, kunezinto ezimbili (zombili nge- Voronoi Umdwebo noma Iphethini ) kanye nemicibisholo emibili ebomvu ibonisa izinhlaka ezisekela kakhulu ukweseka. Kulezi zimo, lokho okushiwo yizinto ezivele ziphukile lapho ngisebenzisa iminwe yami.
Ngabe ngisebenzisa isilwane se-needlenose ngenye yayo kanye nommese we-putty nge-edge edge ebukhali ingxenye yayo. Abantu abaningi basikisela imicu ye-Xacto, kodwa nakakhulu ukudikibala ngoba isiliphu esisodwa siphuca ngomunwe ohlanganyelwe negazini entweni yakho ephrintiwe ye-3D. I-Bummer.
Indlela elula kakhulu yokususa ukwesekwa ukuthenga iphrinta ye-3D ehlongozwe ngokukhipha ama-3D ngoba ungakwazi ukulayisha impahla ejwayelekile ye- PLA noma ye-ABS ye-extruder eyinhloko kanye nokwesekwa okuphansi kokuxhasana komunye. Lokho okusekelwayo ngokuvamile kuvuthwa endaweni yokugeza kwamanzi yamakhemikhali. I-Stratasys Mojo engiyisebenzisayo emgwaqweni we-3DRV inikeza lolu hlobo lokusondela. Okumnandi, kodwa-ke kwakungumshini wokubolekisa kuphela wephrojekthi futhi, njengoba ngithola, mina kanye nabanye, hhayi ngaso sonke isikhathi ngaphakathi kwesabelomali ububanzi bomuntu ojwayele ukuthenga umthengi.
Uma uhlela into yakho noma uthenge umkhiqizo ophelile ngokusebenzisa i- 3D service yokunyathelisa , njenge-Shapeways, khona-ke ungakhetha izinga lokuqeda ufisa, ngaleyo ndlela ube nomunye umuntu ekuqedeni umsebenzi.
Kodwa, iningi lethu lizodinga ngesandla ukucubungula le nto yokusekela ngandlela-thile. Ngaphandle kwemiqondo evamile ngezansi, nanka amanye amathiphu nemibono engayithola ekufundeni izinkundla ezahlukene. Enye yezintambo zami engizithandayo ku-Hubs ye-3D: Indlela Engcono kakhulu Yokukhipha Ama-Rafts, Ukusekela, nokunye ukuFilament Okubanzi.
Iningi leziphakamiso libandakanya isigaba sokuphrinta ngaphambi kokuthi wenze njengoba uSherri Johnson anconyayo - engeza ukwesekwa okuhlakaniphile ngendlela yesofthiwe: Kulula uhlelo olukhokhelwayo, luye lwaphindaphindiwe kusukela ochwepheshe. I-Freeware, njenge-Meshmixer noma i-Netfabb yilabo ababili okukhulunywe lapha.
- Uma usebenzisa ummese noma u-scraper uhlobo oluthile, noma ukushisa imodeli noma i-blade ukwenza kube lula ukusika. I-torch encane ye-butane ingasiza (qaphela kakhulu, ngenxa yesibonelo sakho).
- I-sandpaper ingasebenzisa izimanga. U-Taylor Landry, uMqondisi we-Print Solutions we-MatterHackers uthe ukusikwa kwe-weting nge-high-grade sandpaper-220 kuya ku-1200 kuzosusa isakhiwo bese kupholisa imodeli yakho. Wanezela "ukuthi i-polish engcono kakhulu esiyibonile ifinyeleleke yizingxenye ezithintekayo ezithombeni ngokusebenzisa izibhamu zokhuni zethusi njengezindaba. (Insimbi engenalutho ingasetshenziswa kuma-filaments we-SS). "Ngakho uma usebenzisa ama-filament exotic exotic, zama i-tumbler. (LINK LINK ku-protopasta)
- Nge-PLA ungathola amamaki okucindezeleka lapho impahla yokusekela ivela kude nomodeli kanye nomsebenzisi oyedwa ephakanyisiwe nge-nail polish varnish ukuze abambe isikhalazo namamaki.
- Uma usukhulile ukusebenzisa isitolo sakho sokunyathelisa se-3D njengomjoka wamazinyo, thola ithuluzi elincane elifana ne-drill elibizwa ngokuthi i-Dremel. Laba bagayiwe ngesandla, abanezinhlobonhlobo zezinkinobho nezinamathiselo, bangenza izinto zokusekela kalula. Yiqiniso, uma ungenayo izandla njengodokotela ohlinzayo noma udokotela wamazinyo, yiba nokuqapha okukhulu ekudaleni kwakho okulula ukubhubhisa epulasitiki.
Nginedivaysi yohlu lwe-rock tumbler engizozama njengendlela yokususa isakhiwo sangaphakathi sokusekela futhi ngizobika.
