Imoto Yamathoyizi yokuphrinta ye-3D

Isingeniso sokuphrinta kwe-3D:

Kuyini ukuphrinta kwe-3D?
Ukuphrinta kwe-3D kuwubuchwepheshe obungeziwe obusetshenziselwa ukwenza izingxenye.'Iyengeza' ngoba ayidingi ibhulokhi lento noma isikhunta ukwenza izinto ezibonakalayo, ivele inqwabelene futhi ihlanganise izingqimba zezinto.Ivamise ukushesha, nezindleko zokusetha ezingaguquki eziphansi, futhi ingakha amajiyometri ayinkimbinkimbi kunobuchwepheshe 'bendabuko', ngohlu olukhula njalo lwezinto zokwakha.Isetshenziswa kakhulu embonini yobunjiniyela, ikakhulukazi ukwenza i-prototyping nokudala amajiyometri angasindi.

Ukuphrinta kwe-3D kanye ne-prototyping esheshayo
'I-Rapid prototyping' ingenye inkulumo ngezinye izikhathi esetshenziselwa ukubhekisela kubuchwepheshe bokuphrinta be-3D.Lokhu kubuyela emuva emlandweni wokuqala wokuphrinta kwe-3D lapho ubuchwepheshe buqala ukuvela.Ngawo-1980, lapho amasu okunyathelisa e-3D eqala ukusungulwa, abizwa ngokuthi ubuchwepheshe bokwenza ama-prototyping ngokushesha ngoba ngaleso sikhathi ubuchwepheshe babufaneleka kuphela ama-prototypes, hhayi izingxenye zokukhiqiza.

Eminyakeni yamuva nje, ukuphrinta kwe-3D sekukhule kwaba yisixazululo esihle kakhulu sezinhlobo eziningi zezingxenye zokukhiqiza, futhi obunye ubuchwepheshe bokukhiqiza (njengomshini we-CNC) buye bashibhile futhi bufinyeleleka kalula kuma-prototyping.Ngakho-ke ngenkathi abanye abantu besasebenzisa 'i-prototyping esheshayo' ukubhekisela ekuphrinteni kwe-3D, leli gama liyashintsha ukuze libhekisele kuzo zonke izinhlobo ze-prototyping eshesha kakhulu.

Izinhlobo ezahlukene zokuphrinta kwe-3D
Amaphrinta e-3D angahlukaniswa abe olulodwa lwezinhlobo ezimbalwa zezinqubo:

I-Vat Polymerization: i-photopolymer ewuketshezi yelashwa ngokukhanya
I-Material Extrusion: i-thermoplastic encibilikisiwe ifakwa ngombhobho oshisayo
I-Powder Bed Fusion: izinhlayiya zempushana zihlanganiswa umthombo wamandla aphezulu
I-Material Jetting: amaconsi e-ejenti e-photosensitive fusing ewuketshezi afakwa embhedeni oyimpuphu futhi elashwa ukukhanya.
I-Binder Jetting: amaconsi e-ejenti ebopha uketshezi afakwa embhedeni wezinto ezisanhlamvu, ezibuye zihlanganiswe ndawonye.
I-Direct Energy Deposition: insimbi encibilikisiwe ifakwe kanyekanye futhi yahlanganiswa
I-Sheet Lamination: amashidi ezinto ezibonakalayo ayasikwa ukuze alolonge futhi ahlanganiswe ndawonye
