Icapiro rya 3Dnuburyo busanzwe bwa resin ya 3D yo gucapa imaze kumenyekana cyane kubushobozi bwayo bwo gukora neza-isotropic, na protototypes yamazi hamwe n-imikoreshereze yanyuma mubice bitandukanye byiterambere hamwe nibintu byiza kandi birangiye neza.
SLA ni mubyiciro byo gucapa 3D.Ababikora bakoresha SLA kugirango bakore ibintu bitandukanye, moderi, na prototypes bakoresheje resin yamazi nkibikoresho byibanze.Mucapyi ya SLA 3D yateguwe hamwe n'ikigega kirimo ibisigazwa by'amazi.Na none, zitanga ibintu bitatu-bingana mugukomera ibisigara byamazi ukoresheje lazeri ifite ingufu nyinshi.Mucapyi ya SLA 3D ihindura ibisigazwa byamazi mubice bitatu bya plastiki yibice byurwego binyuze murwego rwo gufotora.Iyo ikintu kimaze gucapurwa 3D, serivise yo gucapa 3D itanga umurongo kuri platifomu.Nanone, akiza icyo kintu abishyira mu ziko rya UV nyuma yo koza ibisigazwa bisigaye.Pose-gutunganya ifasha abayikora kubintu byimbaraga nziza kandi zihamye.
Umubare munini wabakora baracyahitamoUbuhanga bwo gucapa 3Dgukora prototypes yubwiza buhanitse kandi bwuzuye.Hariho nimpamvu zitari nke zituma abayikora benshi bagikunda SLA kurindi tekinoroji ya 3D yo gucapa.
1.Byiza Byinshi Kurindi Tekinoroji yo gucapa 3D
SLA yatsinze ibihe bishya Ubuhanga bwo gucapa 3Dmu cyiciro cyukuri.Mucapyi ya SLA 3D ibika ibice bya resin kuva kuri 0,05 mm kugeza kuri 0,10 mm.Kandi, ikiza buri cyiciro cya resin ikoresheje urumuri rwiza rwa laser.Kubwibyo, abayikora bakoresha printer ya SLA 3D kugirango batange prototypes zifite iherezo ryuzuye kandi rifatika.Barashobora kandi gukoresha tekinoroji kuri 3D icapa geometrike.
2.Uburyo butandukanye bwa resin
Mucapyi ya SLA 3D ikora ibintu nibicuruzwa biva mumaziresin.Uruganda rufite amahitamo yo gukoresha resin zitandukanye - resin isanzwe, resin ibonerana, ibara risa, mamoth resin, hamwe nubusobanuro buhanitse.Rero, uruganda rushobora kubyara igice gikora ukoresheje uburyo bukwiye bwa resin.Na none, arashobora kugabanya byoroshye ibiciro byo gucapa 3D akoresheje resin isanzwe itanga ubuziranenge butahenze.
3. Itanga Ubworoherane Bwinshi bwa Dimensional Tolerance
Mugihe cyo gukora prototypes cyangwa gukora ibice bikora, abayikora bashakisha tekinoroji yo gucapa ya 3D itanga urugero rwiza.SLA itanga kwihanganira urwego rukomeye.Itanga +/- 0.005 ″ (0,127 mm) kwihanganira ibipimo bya santimetero yambere.Mu buryo nk'ubwo, itanga 0.002 ″ kwihanganira ibipimo kuri buri santimetero ikurikira.
4.Ikosa rito ryo gucapa
SLA ntabwo yagura ibice byamazi akoresheje ingufu zumuriro.Yakuyeho kwaguka k'ubushyuhe mu gukomera resin ukoresheje UV laser.Gukoresha UV laser nkibice byo guhinduranya amakuru bituma SLA ikora neza mukugabanya amakosa yo gucapa.Niyo mpamvu;ababikora benshi bashingira kuri tekinoroji ya 3D ya SLA kugirango ikore ibice bikora, imiti yubuvuzi, ibice byimitako, imiterere yububiko bwububiko, hamwe nuburyo busa neza.
5.Icyoroshye kandi cyihuse nyuma yo gutunganywa
Resin nimwe mubikunzwe cyaneIbikoresho byo gucapa 3Dkubera koroshya nyuma yo gutunganya.Abatanga serivise zo gucapa 3D barashobora kumucanga, gusiga, no gusiga irangi ibikoresho bitarinze gushiramo igihe n'imbaraga.Muri icyo gihe, uburyo bwo gukora icyiciro kimwe gifasha tekinoroji yo gucapa SLA 3D kubyara ubuso bworoshye budasaba kurangiza.
6.Gushyigikira Byinshi Byubaka
Kimwe nubuhanga bushya bwo gucapa 3D, SLA ishyigikira ubwinshi bwubaka.Uruganda rushobora gukoresha printer ya SLA 3D kugirango ikore amajwi agera kuri 50 x 50 x 60 cm³.Kubwibyo, abayikora barashobora gukoresha printer imwe ya SLS 3D kugirango bakore ibintu na prototypes yubunini nubunzani.Ariko tekinoroji ya 3D ya SLA ntabwo itanga cyangwa ngo ibangikanye neza mugihe icapiro rya 3D rinini ryubaka.
7.Igihe cyo gucapa 3D
Ba injeniyeri benshi barabyizeraSLAni gahoro kuruta tekinoroji ya 3D yo gucapa.Ariko uruganda rushobora gukoresha printer ya SLA 3D kugirango itange igice cyuzuye cyangwa ibice byuzuye mumasaha agera kuri 24.Ingano yigihe gisabwa nicapiro rya SLA 3D kugirango ikore ikintu cyangwa igice kiracyatandukanye ukurikije ubunini nigishushanyo cyikintu.Mucapyi izakenera igihe kinini kugirango 3D icapye igoye igizwe na geometrike igoye.
8.Gabanya igiciro cyo gucapa 3D
Bitandukanye nubundi buryo bwa 3D bwo gucapa, SLA ntabwo isaba abatanga serivise zo gucapa 3D kugirango bakore ibishushanyo.Icapisha 3D-ibintu bitandukanye wongeyeho amazi ya resin kumurongo.UwitekaSerivisi yo gucapa 3Dabatanga isoko bashobora gukora ibintu bya 3D biturutse muri dosiye ya CAM / CAD.Kandi, barashobora gushimisha abakiriya mugutanga ikintu cyacapwe 3D mugihe kitarenze amasaha 48.
Nubwo ari tekinoroji yo gucapa ya 3D ikuze, SLA iracyakoreshwa nababikora naba injeniyeri.Ariko umuntu ntagomba kwibagirwa ko tekinoroji ya 3D ya SLA ifite ibyiza byayo nibibi.Abakoresha barashobora gukoresha ibyiza bya tekinoroji ya SLA 3D yo gucapa gusa bibanda ku gutsinda ibitagenda neza.Amashusho akurikira ni SLA yo gucapa ibyitegererezo byawe:
Niba ushaka kumenya amakuru menshi kandi ukeneye gukora moderi yo gucapa 3d, nyamuneka hamagaraJSADD Uruganda rwa 3Digihe cyose.
