Kungani udinga iphrinta ye-SLA yezimboni ye-3D.

Ngamaphrinta we-3D wedeskithophu ethengekayo, izinto zokuphrinta ze-3D ezimelana nezinga lokushisa, nemishini yokubumba umjovo, kungenzeka ukuthi udale isikhunta somjovo esiphrintiwe se-3D endlini ukuze kukhiqizwe ama-prototypes asebenzayo nezingxenye ezincane, ezisebenzayo kumapulasitiki okukhiqiza. Ngokukhiqizwa kwevolumu ephansi (izingxenye ezingaba yi-10-1000), isikhunta somjovo esiphrintiwe se-3D silondoloza isikhathi nemali uma kuqhathaniswa nezibunjwa zensimbi ezibizayo. Ziphinde zinike amandla indlela yokukhiqiza eshesha kakhudlwana, evumela onjiniyela nabaklami ukuthi benze imodeli yokubunjwa komjovo kanye nokuhlola ukucushwa kwesikhunta noma baguqule kalula ukubumba futhi baqhubeke nokuphindaphinda imiklamo yabo ngezikhathi eziphansi zokuhola nezindleko.

Ubuchwepheshe bokuphrinta be-SLA 3D buyisinqumo esihle sokubumba. Ibonakala ngokuqedwa okubushelelezi kanye nokunemba okuphezulu ukuthi isikhunta sizodlulisela engxenyeni yokugcina futhi lokho kusiza ukudiliza. Amaphrinti e-3D akhiqizwa yi-SLA ahlanganiswe ngamakhemikhali kangangokuthi aminyene ngokugcwele futhi asotropic, akhiqiza isikhunta esisebenzayo ngekhwalithi engenakwenzeka nge-fused deposition modelling (FDM). Amaphrinta e-SLA edeskithophu nawebhentshi, afana nalawo anikezwa Amafomula, enza ukuhamba komsebenzi kube lula njengoba kulula ukuwasebenzisa, ukuwasebenzisa, nokuwanakekela.

I-Formlabs Rigid 10K Resin iyinsimbi yezinga lezimboni, egcwele ingilazi kakhulu esebenza njengento efanelekile yokubumba yezinhlobonhlobo zamajiyometri nezimo zenqubo yokubumba umjovo. I-Rigid 10K Resin ine-HDT engu-218 ° C @ 0.45 MPa kanye ne-tensile modulus engu-10,000 MPa, okuyenza ibe into eqinile, eqinile kakhulu, futhi eqinile ngokushisa okushisayo ezogcina isimo sayo ngaphansi kwengcindezi kanye nezinga lokushisa ukuze ikhiqize izingxenye ezinembile.

I-Rigid 10K Resin iwumsebenzi wokuphrinta isikhunta esiyinkimbinkimbi sokubumba umjovo, esikubonisa ngezifundo eziyizikesi ezintathu ephepheni lethu elimhlophe. Isikhungo sezobuchwepheshe sezimboni saseFrance i-IPC yenze ucwaningo futhi yaphrinta izinkulungwane zezingxenye, umenzi wenkontileka i-Multiplus iyisebenzisela ukukhiqizwa kwevolumu ephansi, futhi inkampani yokuthuthukisa umkhiqizo i-Novus Applications ijove amakhulu amakepisi anentambo eyinkimbinkimbi ngesikhunta esisodwa se-Rigid 10K Resin.

I-High Temp Resin ingenye into engacatshangelwa lapho ukugoqa kanye nezingcindezi zokujova zingekho phezulu kakhulu futhi iRigid 10K Resin ayikwazi ukuhlangabezana namazinga okushisa adingekayo. I-High Temp Resin inezinga lokushisa elishintshashintshayo lokushisa (i-HDT) elingu-238°C @ 0.45 MPa, eliphakeme kakhulu phakathi kwama-Formlabs resin futhi ingelinye eliphezulu kakhulu phakathi kwama-resin emakethe, elivumela ukuthi limelane namazinga okushisa aphezulu kanye nokunciphisa isikhathi sokupholisa. Iphepha lethu elimhlophe lidlula ocwaningweni lwe-Braskem, inkampani ye-petrochemical eyasebenzisa imijikelezo yomjovo eyi-1,500 enokufakwa kwesikhunta okukodwa okuphrintwe nge-High Temp Resin ukuze kukhiqizwe amabhande imaski. Inkampani yaphrinta okufakiwe futhi yakubeka ngaphakathi kwesikhunta sensimbi esijwayelekile esihlanganiswe ohlelweni lomjovo. Lesi yisixazululo esinamandla sokukhiqiza uchungechunge olumaphakathi ngokushesha.

I-High Temp Resin, nokho, i-brittle impela. Endabeni yomumo oyinkimbinkimbi, iyasonteka noma iqhekeke kalula. Kwamanye amamodeli, ukufinyelela imijikelezo engaphezu kweshumi nambili kungaba inselele. Ukuze kuxazululwe le nselele, Inomoya oshisayo ophansi kune-High Temp Resin, okuholela esikhathini sokupholisa eside, kodwa ithambile futhi ingakwazi ukumelana namakhulu emijikelezo.
