1. I-SLA
I-SLA iyimboniUkuphrinta kwe-3Dnoma inqubo yokukhiqiza okungeziwe esebenzisa i-laser elawulwa ngekhompuyutha ukuze yakhe izingxenye echibini leresin ye-photopolymer elapheka nge-UV. I-laser iveza futhi yelapha ingxenye ephambanayo yomklamo wengxenye ebusweni beresin ewuketshezi. Ungqimba olulashiwe lube sehliswa ngokuqondile ngaphansi kwendawo ye-resin ewuketshezi futhi inqubo iyaphindwa. Isendlalelo ngasinye esisanda kwelashwa sinamathiselwe kungqimba olungezansi kwalo. Le nqubo iyaqhubeka kuze kube yilapho ingxenye isiqediwe.
Izinzuzo:Kumamodeli omqondo, ama-prototypes wezimonyo nemiklamo eyinkimbinkimbi, i-SLA ingakhiqiza izingxenye ezinamajiyometri ayinkimbinkimbi kanye nokuqedwa okuhle kakhulu kwendawo uma kuqhathaniswa nezinye izinqubo zokungeza. Izindleko ziyaqhudelana futhi ubuchwepheshe butholakala emithonjeni eminingi.
Ububi:Izingxenye ze-prototype zingase zingabi namandla njengezingxenye ezenziwe ngama-resin ebanga lobunjiniyela, ngakho izingxenye ezenziwe kusetshenziswa i-SLA zinokusetshenziswa okulinganiselwe ekuhloleni ukusebenza. Ngaphezu kwalokho, lapho izingxenye zingaphansi kwemijikelezo ye-UV ukuze zelaphe indawo engaphandle yengxenye, ingxenye eyakhelwe ku-SLA kufanele isetshenziswe ngokuchayeka kwe-UV encane kanye nomswakama ukuze kuvinjelwe ukuwohloka.
2. I-SLS
Enqubweni ye-SLS, i-laser elawulwa ngekhompuyutha idonswa kusukela phansi kuye phezulu phezu kombhede oshisayo wempushana esekwe inayiloni, efakwe ngobumnene (ihlanganiswe) ibe into eqinile. Ngemuva kwesendlalelo ngasinye, i-roller ibeka ungqimba olusha lwempushana phezu kombhede futhi inqubo iyaphindwa.I-SLS isebenzisa inayiloni eqinile noma impushana ye-TPU eguquguqukayo, efana ne-thermoplastics yobunjiniyela bangempela, ngakho izingxenye zinokuqina okukhulu nokunemba, kodwa indawo emagebhugebhu futhi ayinayo imininingwane emihle.I-SLS inikezela ngevolumu enkulu yokwakha, ivumela ukukhiqizwa kwezingxenye ezinejometri eyinkimbinkimbi futhi idale ama-prototypes ahlala isikhathi eside.
Izinzuzo:Izingxenye ze-SLS zivame ukunemba kakhulu futhi ziqine kunezingxenye ze-SLA. Inqubo ingakhiqiza izingxenye eziqinile ezinamajiyometri ayinkimbinkimbi futhi ifanele ezinye izivivinyo zokusebenza.
Ububi:Izingxenye zinokuthungwa okusanhlamvu noma kwesihlabathi futhi izinketho ze-resin zenqubo zilinganiselwe.
3. CNC
Ekwenziweni komshini, ibhulokhi eqinile (noma ibha) yepulasitiki noma yensimbi iboshelwe ku-aI-CNC yokugayanoma umshini wokuguqula futhi usike umkhiqizo oqediwe ngomshini okhiphayo, ngokulandelana. Le ndlela ngokuvamile ikhiqiza amandla aphezulu kanye nokuqedwa kwendawo kunanoma iyiphi inqubo yokukhiqiza okungeziwe. Iphinde ibe nezinto ezigcwele, ezilinganayo zepulasitiki njengoba zenziwa ngamabhulokhi aqinile aqinile noma acindezelwe we-thermoplastic resin, ngokungafani nezinqubo eziningi ezingeziwe, ezisebenzisa izinto ezifana nepulasitiki futhi zakhe ngezingqimba. Uhlu lwezinketho zezinto ezibonakalayo luvumela ingxenye ukuthi ibe nezinto ezibonakalayo ezifiselekayo ezifana nalezi: amandla aqinile, ukumelana nomthelela, izinga lokushisa lokushintsha ukushisa, ukumelana namakhemikhali kanye ne-biocompatibility. Ukubekezelela okuhle kukhiqiza izingxenye, ama-jig kanye nezakhiwo ezifanele ukuhlolwa kokufaneleka nokusebenza, kanye nezingxenye ezisebenzayo zokusetshenziswa ekugcineni.
Izinzuzo:Ngenxa yokusetshenziswa kwe-thermoplastics yebanga lobunjiniyela nezinsimbi kumishini ye-CNC, izingxenye zinendawo enhle yokuqeda futhi ziqine kakhulu.
Ububi:Imishini ye-CNC ingaba nemikhawulo ethile yejometri futhi ngezinye izikhathi kubiza kakhulu ukwenza lo msebenzi endlini kunenqubo yokuphrinta ye-3D. Ama-milling nibbles kwesinye isikhathi angaba nzima ngoba inqubo isusa izinto kunokungeza.
4. Ukubumba umjovo
Ukubumba umjovo osheshayoisebenza ngokujova inhlaka ye-thermoplastic esikhunjeni futhi okwenza inqubo 'isheshe' ubuchwepheshe obusetshenziswa ukukhiqiza isikhunta, esivame ukwenziwa nge-aluminium kunensimbi yendabuko esetshenziselwa ukukhiqiza isikhunta. Izingxenye ezibunjiwe ziqinile futhi zinendawo enhle kakhulu yokuqeda. Lokhu futhi kuyinqubo evamile yokukhiqiza yezingxenye zepulasitiki, ngakho-ke kukhona izinzuzo zemvelo zokwenziwa kwe-prototyping ngenqubo efanayo uma izimo zivuma. Cishe noma iyiphi ipulasitiki yebanga lobunjiniyela noma irabha ye-silicone ewuketshezi (LSR) ingasetshenziswa, ngakho-ke abaklami abanqunyelwe izinto ezisetshenziswa enqubweni ye-prototyping.
Izinzuzo:Izingxenye ezibunjiwe ezenziwe ngohlu lwezinto zebanga lobunjiniyela ezinemiphetho emihle kakhulu yangaphezulu ziyisibikezelo esihle kakhulu sokwenziwa kwesigaba sokukhiqiza.
Ububi:Izindleko zamathuluzi zokuqala ezihambisana nokubumba komjovo ngokushesha azenzeki kunoma yiziphi izinqubo ezengeziwe noma umshini we-CNC. Ngakho-ke, ezimweni eziningi, kunengqondo ukwenza umjikelezo owodwa noma emibili ye-prototyping esheshayo (ekhiphayo noma engezayo) ukuze uhlole ukulingana nokusebenza ngaphambi kokudlulela ekubumbeni umjovo.
