Inkonzo yoShicilelo ye-3D yobuNgcali
Ukwaziswa koShicilelo lwe-SLS 3D
Itekhnoloji ye-Selective Laser Sintering (SLS) yasungulwa nguCR Decherd weYunivesithi yaseTexas e-Austin.Yenye yeetekhnoloji zokuprinta ze-3D ezinemigaqo enzima yokwenza, iimeko eziphezulu, kunye neendleko eziphezulu zezixhobo kunye nezinto eziphathekayo. Nangona kunjalo, iseyeyona teknoloji ifikelela kude ekuphuhliseni iteknoloji yoshicilelo lwe-3D.
Nantsi indlela esebenza ngayo.
Le yindlela egqibezela ngayo imveliso yemodeli. Izinto zomgubo zifakwa umaleko ngokomaleko kwiqondo lobushushu eliphezulu phantsi kweradiation yelaser, kwaye ikhompyutha ilawula isixhobo sokubeka umthombo wokukhanya ukufikelela kwindawo echanekileyo. Ngokuphinda inkqubo yokubeka umgubo kunye nokunyibilika apho kuyimfuneko, iinxalenye zakhiwe kwibhedi yomgubo
Iingenelo
- Inkqubo elula yokuvelisa: Le nkqubo inokuvelisa ngokuthe ngqo iiprototypes, iinxalenye kunye nezixhobo zeemilo ezinzima ngokwezinto ezahlukeneyo.
- Akukho nkxaso eyongezelelweyo: I-SLS ayifuni isakhiwo senkxaso, kwaye uluhlu olumisiwe olubonakala ngexesha lokupakisha lunokuxhaswa ngokuthe ngqo kwipowder engabonakaliyo.
- Iimpawu ezigqwesileyo zoomatshini: Itekhnoloji ye-SLS isebenzisa iiplastiki ze-polymer ezifana neyiloni, ngoko ke iindawo eziprintiweyo zihlala zineempawu ezintle zoomatshini, ukuxhathisa ubushushu kunye nokumelana neekhemikhali. Ukongeza kuphando kunye neenjongo zokuvavanya uphuhliso, zinokusetyenziswa ngokuthe ngqo kwiimveliso zokugqibela.
- Ukubumba okuphezulu. Ekubeni iteknoloji ye-SLS ayinyibiliki ngokupheleleyo i powder, kodwa i-sinters kuphela, isantya sokuvelisa sikhawuleza.
- Izinga eliphezulu lokusetyenziswa kwemathiriyeli: Ngenxa yokuba akukho mfuneko yokuxhasa kunye nokongeza isiseko, inelona zinga liphezulu lokusetyenziswa kwemathiriyeli phakathi kwetekhnoloji eqhelekileyo yoshicilelo lwe-3D.
Iingxaki
- Iindleko eziphezulu zezixhobo kunye neendleko zokugcina: Ngenxa yokusetyenziswa kwe-laser ezinamandla amakhulu, izixhobo ezizezakho, inkqubo eninzi yokukhusela encedisayo kunye nobunzima bobugcisa ngokubanzi, iindleko zokuvelisa kunye nokugcinwa ziphezulu kakhulu.
- Umgangatho womphezulu awuphezulu: Ukuthetha ngokuthe ngqo, umphezulu weprototype ngumgubo, ngoko awukwazi ukuhlangabezana neemfuno zabathengi abaqhuba umgangatho ophezulu.
Amashishini ane-SLS 3D Printing

iPost Processing
Iimodeli eziprintwe ngenayiloni zihlala zifumaneka ngengwevu namhlophe, kodwa sinokuzintywilisela ngemibala eyahlukeneyo ngokweemfuno zabathengi.
Izinto ze-SLS
Izixhobo ze-SLS zibanzi kakhulu. Ngokwethiyori, nayiphi na into yomgubo enokuthi yenze i-interatomic bonding emva kokufudumeza ingasetyenziswa njengezinto zokubumba ze-SLS, ezinje ngeepolima, isinyithi, iiseramics, igypsum, inayiloni, njl.
I-90% yezinto ezisetyenziswa kwi-SLS kwimarike yinayiloni, ngoko ke abantu bahlala becinga ukuba inayiloni yimpahla ye-SLS. Iimathiriyeli zenayiloni ezisetyenziswa ngokuqhelekileyo yi-PA12 kunye ne-PA12+GF.
| SLS | Umzekelo | Uhlobo | Umbala | Ubuchwephesha | Umaleko ubukhulu | Iimbonakalo |
 | Inayiloni yaseTshayina | PA 12 | Mhlophe/Mpunga/Mnyama | SLS | 0.1-0.12mm | Amandla aphezulu kunye nokuqina olomeleleyo |
