Isevisi Yokuphrinta ye-3D yobungcweti
Ukwethulwa Kokuphrinta kwe-SLS 3D
Ubuchwepheshe be-Selective Laser Sintering (SLS) basungulwa ngu-CR Decherd waseNyuvesi yaseTexas e-Austin.Ingobunye bobuchwepheshe bokuphrinta be-3D obunezimiso zokwakha eziyinkimbinkimbi kakhulu, izimo eziphakeme kakhulu, kanye nezindleko eziphezulu kakhulu zemishini nezinto ezibonakalayo. Nokho, kusewubuchwepheshe obufinyelela kude kakhulu ekuthuthukisweni kobuchwepheshe bokuphrinta be-3D.
Nansi indlela esebenza ngayo.
Lena yindlela eqeda ngayo ukukhiqizwa kwamamodeli. I-powder material ifakwe ungqimba ngongqimba ekushiseni okuphezulu ngaphansi kwemisebe ye-laser, futhi ikhompuyutha ilawula idivayisi yokubeka umthombo wokukhanya ukuze ifinyelele indawo enembile. Ngokuphinda inqubo yokubeka impushana nokuncibilika lapho kudingeka khona, izingxenye zakhiwe embhedeni wempuphu
Izinzuzo
- Inqubo elula yokukhiqiza: Le nqubo ingakhiqiza ngokuqondile ama-prototypes, izingxenye namathuluzi wobunjwa obuyinkimbinkimbi ngokuya ngezinto ezahlukene.
- Akukho ukusekelwa okwengeziwe: I-SLS ayidingi isakhiwo sokusekela, futhi isendlalelo esimisiwe esivela ngesikhathi senqubo yokupakisha singasekelwa ngokuqondile yi-powder engafakiwe.
- Izakhiwo ezinhle kakhulu zemishini: Ubuchwepheshe be-SLS busebenzisa amapulasitiki e-polymer njengenayiloni, ngakho-ke izingxenye eziphrintiwe zivame ukuba nezakhiwo ezinhle zemishini, ukumelana nezinga lokushisa kanye nokumelana namakhemikhali. Ngaphezu kwezinjongo zokuhlola nokuthuthukiswa, zingasetshenziswa ngokuqondile emikhiqizweni yokugcina.
- Ukusebenza kahle kokubumba okuphezulu. Njengoba ubuchwepheshe be-SLS bungancibiliki ngokuphelele i-powder, kodwa buyi-sinters kuphela, isivinini sokukhiqiza siyashesha.
- Izinga eliphezulu lokusebenzisa izinto ezibonakalayo: Ngenxa yokuthi asikho isidingo sokusekela nokwengeza isisekelo, linenani eliphakeme kakhulu lokusebenzisa izinto phakathi kobuchwepheshe obumbalwa obujwayelekile bokuphrinta be-3D.
Ukubi
- Izindleko eziphezulu zemishini nezindleko zokuyilungisa: Ngenxa yokusetshenziswa kwama-laser anamandla amakhulu, okokusebenza okungokwakho, inqubo yokuvikela eyinsalela eminingi kanye nobunzima bobuchwepheshe bubonke, izindleko zokukhiqiza nezokulungisa ziphezulu kakhulu.
- Ikhwalithi yobuso ayiphezulu: Uma sikhuluma ngokuqinile, ingaphezulu lesibonelo liyimpushana, ngakho alikwazi ukuhlangabezana nezidingo zamakhasimende aphishekela izindawo ezisezingeni eliphezulu.
Izimboni ezine-SLS 3D Printing
Indiza Engaphathwa Ngomkhathi / Ubuciko Bobuciko / Imoto / Izingxenye Zemoto / I-Electronic Yasekhaya / Usizo Lwezokwelapha / Izesekeli Zezithuthuthu
Ukuthunyelwa Kucutshungulwa
Amamodeli aphrintwe enayiloni ngokuvamile atholakala ngokumpunga nokumhlophe, kodwa singawacwilisa ngemibala ehlukene ngokwezidingo zamakhasimende.
Izinto ze-SLS
Izinto ze-SLS ziningi kakhulu. Ngokwethiyori, noma iyiphi into eyimpushana engakha isibopho se-interatomic ngemva kokushisisa ingasetshenziswa njengezinto zokubumba ze-SLS, ezifana nama-polymers, izinsimbi, izitsha zobumba, igypsum, inayiloni, njll.
U-90% wezinto ezisetshenziswa ku-SLS emakethe inayiloni, ngakho-ke abantu bavame ukucabanga ukuthi inayiloni iyimpahla ye-SLS. Izinto ezisetshenziswa kakhulu inayiloni yi-PA12 ne-PA12+GF.
| I-SLS | Imodeli | Uhlobo | Umbala | Ubuchwepheshe | Ugqinsi lwesendlalelo | Izici |
 | Inayiloni yesiShayina | PA 12 | Mhlophe/Mpunga/Mnyama | I-SLS | 0.1-0.12mm | Amandla aphezulu kanye nokuqina okuqinile |
