I-JS Additive ineminyaka yamava asebenzayo kwiinkonzo zoshicilelo lwe-3D.Ngophando, kwafunyaniswa ukuba kukho izinto ezininzi ezichaphazela ngqo isantya sokubumba se-SLA/DLP/LCD 3D yoshicilelo.Ukuseta isantya esifanelekileyo soshicilelo luncedo ekuphuculeni ukuba nokwenzeka koshicilelo olunempumelelo kunye nokusebenza kakuhle kwemveliso.Kodwa akulula kangako, ngakumbi kwisandla esitsha.Phambi kokuseta isantya esifanelekileyo soshicilelo, kufuneka wazi ukuba zeziphi izinto ezichaphazela isantya soshicilelo se-SLA/DLP/LCD 3D abashicileli.
Iteknoloji yoShicilelo
Xa kuthelekiswa ne-SLA, i-DLP kunye ne-LCD zinenzuzo efanayo, kwaye oko kukukhawuleza kokushicilela.Ezi teknoloji zoshicilelo zimbini ngokucacileyo zikhawuleza.Ngenxa yokuba iiprinta ze-DLP/LCD ze-3D zenziwa kumphezulu wonke, owenziwe ngokutshayela, ngokungafaniyo ne-SLA, eyenziwa ngamachaphaza e-laser.

Izicwangciso zePrinta
Ukuba isantya soshicilelo simiselwe kwangaphambili, asisayi kudlula ixabiso elimiselweyo.
Enye into enxulumene nesantya soshicilelo sisantya apho inkqubo iprinta umaleko omnye.Xa kushicilelwa, umthombo wokukhanya udlula emazantsi esitya sentlaka esicacileyo, kwaye intlaka esandula ukunyangwa ifuna inkqubo edinayo yokuxobula ngaphambi kokuba iqhubeke nokunyanga umaleko omtsha.Abanye abavelisi benza inkqubo idlule kwinkqubo yokuxobula ngokukhawuleza ukunyusa isantya soshicilelo.Enye indlela yokuphelisa le ngxaki kukunyanga phezulu kwinqanaba le-resin, kungekhona ezantsi.
Ubunzulu boMthombo wokuKhanya
Ushicilelo lwe-resin lisebenzisa umthombo wokukhanya ukunyanga intlaka yolwelo ethatha ifoto ukwenza imodeli yokugqibela ye-3D.
Umahluko phakathi kobuchule obuthathu ngumthombo wokukhanya osetyenziselwa ukunyanga i-resin.
Ubunzulu bomthombo wokukhanya osetyenzisiweyo bunokuchaphazela isantya soshicilelo somshicileli.Singayiphucula ngokwandisa ukukhanya, kodwa oko kuthetha iindleko ezongezelelweyo.
UmalekoTukugxadazela
Ubukhulu bomaleko buchaphazela isantya soshicilelo kunye nomgangatho wemodeli.Ubukhulu bomaleko obufunekayo ukuprinta imodeli bumisela isantya soshicilelo kunye nexesha elithathayo.Ubunzima bomaleko buncinci, ixesha elininzi liya kuthatha ukuprinta imodeli ye-3D yobude obufanayo.Ngenxa yokuba ubude bubonke buhlala bufana, okukhona ubhityile ubungqingqwa bomaleko, kokukhona kufuneka iileya umshicileli aprinte, kwaye ixesha elininzi lithatha.Kodwa ngokulinganayo, ubuninzi bobungqimba, buphezulu umgangatho wemveliso egqityiweyo.

Izinto eziphathekayo
Isantya soshicilelo somshicileli we-3D sikwaxhomekeke kuhlobo lwemathiriyeli.Iiresin ezidityaniswe ziimonomers ezahlukeneyo, ii-prepolymers, iifotoinitiators, kunye nezinye izongezo ezahlukeneyo zineempawu ezahlukeneyo kunye namaxesha ahlukeneyo okunyanga.
Ulwakhiwo kunye nokuBekwa koMfanekiso
Ubume bomzekelo buchaphazela isantya soshicilelo.Ukuba imodeli ivalekile kwaye ayinazo iinkcukacha ezintsonkothileyo, ukuprinta kukhawuleza kakhulu.Ukubekwa okufanelekileyo komzekelo kuya kuchaphazela nesantya soshicilelo.Ngokubanzi, kuya kukhawuleza kakhulu ukubeka imodeli ngokuthe tye kunokuba ngokuthe nkqo xa kushicilelwa, kodwa ukuchaneka kunokuncitshiswa.
Ezi zizinto eziphambili ezichaphazela isantya soshicilelo phakathi koshicilelo lwe-3D.Kwinkqubo yokuvelisa okongeziweyo, imeko yangempela ingaba nzima ngakumbi kunoko.Ke ngoko, isantya soshicilelo lurhwebo.Nje ukuba isantya soshicilelo sinyuke, kunokwenzeka ukuba umgangatho woshicilelo uyakwehla.Indlela yokubeka ubungakanani bezinto ezilungileyo kunye nezibi nazo kufuneka zigqitywe ngokweyona meko.
