Izinsiza zokusiza ukuthi uthole ukuthi iyiphi into efanele yephrojekthi yakho ye-3D
Imvilophu enamandla yafika futhi ngaphakathi kwakuyibhola le-titanium elinyathelisiwe le-3D elinyatheliswa yi-Morris Technologies (eyatholakala yi-GE Aviation). UTerry Wohlers, oyedwa ochwepheshe bezokunyathelisa abaphezulu be-3D, wangithumela kimi ukukhombisa ukuthi insimbi enamandla ephrintiwe ye-3D ingaba kanjani. Watshelwa ukuthi le nqola ekhanyayo, eyinkimbinkimbi, nekhono elibukeka liqinile ngokwanele ukuze ukwazi ukuma kuyo.
Ingabe inamandla ngokwanele? Lona ngumbuzo ovamile abantu abawubuza mayelana nento yokugcina ye-3D ephrintiwe, ngokujwayelekile.
Engqondweni yami, njengoba kungenzeka ukuthi abanye bakucabangayo, ngiyazibuza ukuthi ngithatha isikhathi, imali, nokuzikhandla ekunyatheliseni okuthile kwe-3D - ingabe kuyoba namandla njengomkhiqizo engingayithenga-eshalofini? Umbuzo omuhle.
Abantu abaningi bacela futhi abantu abaningi bafuna futhi bahlola amandla omzimba. Abaningi babo bangososayensi, njenge-duo engiye ngahlangana nayo eFrance Motor Company ukuhlola ukuhlolwa kwezingxenye ezahlukene ze-3D ngokufakaza nge-X inani lesisindo. Umsebenzi omuhle kufanele ube, ukuhlola amaphuzu okuphulwa. Gqoka izibuko zakho zokuphepha.
Ubuntu be-YouTube, uThomas Sanladerer, kudala amavidiyo avamile ngokunyathelisa kwe-3D okuthiwa nje: Umhlahlandlela kaTom noma kaTom. Wenza ukuhlolwa kwakhe kwe-3D ukuphrinta impahla yokuzijabulisa ongayibona lapha.
Ngakho-ke, ukusika ukuxosha, amandla akulula ngaso sonke isikhathi ukuchaza - kuxhomeke kulokho okwenzayo ngemuva kokuwushintsha. Ingabe uyiphonsa? Ukulenga okuthile kulo? Ingabe kudinga ukumelana nomthelela noma ukushisa?
Enye yezinsiza ezingcono kakhulu zokuphendula enye yale mibuzo itholakala ku-CAPUniversity - okuyinto ibhulogi ebhalwe umdayisi weSolidworks eNyakatho-mpumalanga ye-USA. Ekuthumeni kwabo, engikukhuthaza ukuba uhambe ufunde: Ukukhetha Izinto Zakho Zokunyathelisa Zama-3D: Kungaphezu Kwamandla Kunamandla!
Baveza amandla okusebenza okuvamile: ABS, PLA, iNylononi nabanye.
Nginikeza imininingwane ethile yobuchwepheshe ku-ABS naku-PLA lapha . Nakhu okuvela ku-CAPUniversity ngokusekelwe emandleni okuqina - okuphansi kakhulu kuya phezulu.
| ABS | I-33MPa (4,700 i-psi) |
| Inayiloni | I-48MPa (7,000 i-psi) |
| I-PLA | 50MPa (7,250 psi) |
| I-PC | I-68MPa (9,800 i-psi) |
| I-PEI | I-81MPa (11,735 i-psi) |
I-ABS, i-PLA, ne-Nylon yizinto ezivamile zokunyathelisa ze-3D.
I-PC imele i-polycarbonate futhi ingenye ye-thermoplastics yezimboni ezisetshenziswa kabanzi kakhulu, kodwa awuzwa ngabantu abaningi abasebenzisa kumafrinta ehlobo lwe-FFF / FDM 3D. I-RepRap Wikihas ikhasi elihle elichaza ezinye zezinzuzo nezindleko ze-polycarbonate.
IPI yi-Polytherimide (PEI) resin, kodwa igama elidumile lokuhweba ngu-Ultem. I-Ultem ngumndeni we-PEI imikhiqizo eyenziwe ngu-SABIC ngenxa yokuthola i-General Electric Plastics Division ngo-2007. Njengoba ubona eshadini, unamandla amakhulu kakhulu.
Enye insiza yi-Stratasys, ekhishwe i-PDF: I-Thermoplastics: Okukhethwa Kakhulu Kunokuprinta Kwe-3D. Amakhasi ayisithupha nje kuphela, futhi axhomeke ezintweni ezisebenza kuma-printers eStratasys, kodwa-ke, kuyisisetshenziswa esihle kusukela amaphrinta amaningi eFused Deposition Modeling (FDM); indlela abaphayona ngayo.
Inothi lokugcina: Emuva ku-Titanium Ibhola: Angikhumbuli ukuthi uTerry Wohlers ungitshele lokhu noma cha, kodwa ngacabanga ukuthi ngokuthuka wathi uzoyithumela kimi uma ngivuma ukuma kuyo. Uthe wayenenhliziyo yokuchoboza ibhola elincane, ngobukhulu be-marble endala, kodwa uma ngivuma ukuthi uzoyithumela kimi. Ngathi ngizokwenza ngokuphelele, kodwa lapho sekufika bengingenayo inhliziyo yokuma kuwo, noma! Kuyinto epholile kakhulu ukuyibeka phansi, uma abenzi bephutha ngokuhlolwa kwamandla abo.
