Ukuphrinta kwe-3D kuyinqubo yokukhiqiza esebenzisa amafayela edijithali ukudala izinto ezibonakalayo.Isebenza ngokwendlalela izinto ndawonye kuze kube yilapho umumo oyifunayo ufinyelelwa.Inqubo ingasebenzisa izinto ezihlukahlukene, njengepulasitiki, insimbi, ngisho nokudla.Imikhiqizo ephrintiwe ye-3Dbenza izinguquko kwezokukhiqiza ngokusebenzisa ubuchwepheshe bokukhiqiza okungeziwe ukuze bakhe imiklamo eyinkimbinkimbi, eyenziwe ngokwezifiso nentsha.Lobu buchwepheshe obuthuthukisiwe bunezinhlelo zokusebenza eziningi kuzo zonke izimboni ezahlukahlukene.
I-prototyping yepulasitiki esheshayoukwakhiwa okusheshayo nokungabizi kakhulu kwezingxenye zepulasitiki kusetshenziswa ubuchwepheshe bokukhiqiza okungeziwe ukuze bakhe ama-prototypes asebenzayo ukuze ahlolwe futhi ahlolwe.Isetshenziselwa ukuhlola nokuthuthukisa imiqondo yomkhiqizo ngaphambi kokuthi iye ekukhiqizeni.Ukuphrinta kwe-3D kuvame ukusetshenziswa njengethuluzi le-prototyping elisheshayo ngenxa yekhono layo lokudala izinto ezinembayo ngokushesha.
I-SLA ne-SLS ubuchwepheshe bokuphrinta be-3D obubili.
Izinsizakalo ze-SLA (stereolithography) phrinta i-prototypesebenzisa inhlaka ye-photopolymer ukuze ukhiqize ama-prototypes ngokushesha nangokunembile.Le nqubo yokuphrinta ye-3D enokulungiswa okuphezulu ingakha amamodeli ayinkimbinkimbi futhi anemininingwane yokuqinisekisa umklamo.I-Selective Laser Sintering (SLS)ubuchwepheshe bokuphrinta be-3D obusebenzisa ama-laser anamandla amakhulu ukuncibilikisa izinto eziyimpuphu ezifana nenayiloni noma ungqimba lwensimbi ngongqimba ukuze kwakhiwe izinto eziqinile, eziyinkimbinkimbi nezihlala isikhathi eside.Bobabili ubuchwepheshe busetshenziswa ekwenzeni i-prototyping esheshayo, ukuthuthukiswa komkhiqizo kanye nokukhiqiza ezimbonini ezihlukahlukene.

1.Yibuphi ubuchwepheshe bokuphrinta be-3D obuqine kakhulu?
Amandla obuchwepheshe bokuphrinta be-3D ngokuvamile ancike ezintweni ezisetshenziswayo kanye nesicelo esithile.Obunye ubuchwepheshe bokuphrinta be-3D obuvame ukusetshenziswa obaziwa ngokukhiqiza izingxenye eziqinile nezihlala isikhathi eside buhlanganisa i-selective laser sintering (SLS), i-direct metal laser sintering (DMLS), kanye ne-fused deposition modeling (FDM) imininingwane eqinisiwe kusetshenziswa izinto ezisebenza kakhulu ezifana ne-carbon fibre noma i-glass fiber. .Usilika.Lapho unquma ukuthi yibuphi ubuchwepheshe bokuphrinta be-3D obuzohlangabezana nezidingo zakho kangcono, qiniseka ukuthi ucabangela izidingo ezithile zephrojekthi yakho.
2.Kungani ukuphrinta kwe-SLS kubiza kakhulu?
Ngenxa yokuthi ubuchwepheshe be-SLS budinga i-laser enamandla amakhulu, izinga eliphezulu lokunemba, nokulawula okuqinile kuyo yonke inqubo yokuphrinta, ngisho nephrinta ye-SLS eshibhe kakhulu ibiza kakhulu kuneningi lamamodeli e-fused deposition modelling (FDM) kanye namaphrinta amaningi e-stereolithography (SLA).
3.Yibuphi ububi bokwenziwa kwe-SLS?
Imfucuza ephakeme kunezinye izithasiselo zokukhiqiza
Ngeshwa, i-SLS ikhiqiza udoti othile njengoba impushana esegunjini ishiswa kusengaphambili ukuze ikwazi ukuchayeka kancane ku-laser.Lokhu kungabangela izinhlamvu zezinhlayiya ezisembhedeni oyimpushana ukuthi zihlangane kancane okuphazamisa ikhwalithi yazo ukuze ziphinde zisetshenziswe.
