1. SLA
SLA iindasitiri3D kudhindakana yekuwedzera yekugadzira nzira inoshandisa komputa-inodzorwa laser kugadzira zvikamu mudziva reUV-inorapika photopolymer resin. Iyo laser inotsanangura uye inorapa iyo muchinjiko-chikamu chechikamu dhizaini pamusoro peiyo mvura resin. Iyo yakarapwa layer inozodzikiswa zvakananga pazasi pemvura resin pamusoro uye maitiro anodzokororwa. Imwe neimwe ichangobva kurapwa inonamirwa kune iyo pasi payo. Iyi nzira inoenderera mberi kusvikira chikamu chacho chapera.
Zvakanakira:Kune mamodheru emamodheru, cosmetic prototypes uye yakaoma dhizaini, SLA inogona kuburitsa zvikamu zvine yakaoma geometries uye yakanakisa yepamusoro inopedza zvichienzaniswa nemamwe maitiro ekuwedzera. Mitengo inokwikwidza uye tekinoroji inowanikwa kubva kune akawanda masosi.
Zvakaipa:Zvikamu zveprototype zvinogona kunge zvisina kusimba sezvikamu zvakagadzirwa kubva kumagiredhi einjiniya resin, saka zvikamu zvinogadzirwa uchishandisa SLA zvine mashoma ekushandisa mukuyedza kushanda. Uye zvakare, kana zvikamu zvakaiswa pasi peUV mavhiri ekurapa kunze kwechikamu, chikamu chakavakwa muSLA chinofanirwa kushandiswa neushoma UV uye humidity kuratidzwa kudzivirira kuparara.
2. SLS
Muchirongwa cheSLS, laser-inodzorwa nekombuta inodhonzwa kubva pasi kusvika kumusoro pamubhedha unopisa wenylon-based poda, iyo inoputirwa zvinyoro-nyoro (yakasanganiswa) kuita yakasimba. Mushure mechikamu chimwe nechimwe, roller inoisa hupfu hutsva pamusoro pemubhedha uye nzira yacho inodzokororwa.SLS inoshandisa nylon yakaoma kana flexible TPU powder, yakafanana neinjiniya chaiyo thermoplastics, saka zvikamu zvine kusimba kukuru uye kunyatsojeka, asi ine rough surface uye kushaya ruzivo rwakanaka.SLS inopa mavhoriyamu makuru ekuvaka, inobvumira kugadzirwa kwezvikamu zvine geometries yakaoma uye inogadzira prototypes akasimba.
Zvakanakira:Zvikamu zveSLS zvinowanzove zvakanyanya uye zvakasimba kupfuura zvikamu zveSLA. Maitiro acho anogona kuburitsa mativi akasimba ane yakaoma geometries uye akakodzera kune mamwe anoshanda bvunzo.
Zvakaipa:Zvikamu zvine tsanga kana jecha manyorerwo uye magadzirirwo resin sarudzo ane mashoma.
3. CNC
Mukugadzira, chivharo chakasimba (kana bhaa) chepurasitiki kana simbi chinosungirirwa pane aCNC kugayakana kushandura muchina uye kucheka muchigadzirwa chakapedzwa nekubvisa machining, zvichiteerana. Iyi nzira inowanzo gadzira yakakwira simba uye kupera kwepamusoro pane chero yekuwedzera yekugadzira maitiro. Iyo ine zvakare yakazara, homogeneous zvimiro zvepurasitiki sezvo inogadzirwa kubva kuextruded kana compression yakaumbwa yakasimba mabhuraki ethermoplastic resin, mukupesana neakawanda ekuwedzera maitiro, ayo anoshandisa epurasitiki-senge zvinhu uye kuvaka mumatanda. Rudzi rwezvasarudzo zvezvinhu zvinobvumira chikamu kuti ive neinodiwa zvinhu zvimiro zvakaita se: kusimba simba, kukanganisa kupikisa, kupisa kupisa tembiricha, makemikari kuramba uye biocompatibility. Kushivirira kwakanaka kunogadzira zvikamu, jigs uye zvigadziriso zvakakodzerwa nekukodzera uye basa kuyedza, pamwe neanoshanda zvikamu zvekupedzisira kushandiswa.
Zvakanakira:Nekuda kwekushandiswa kweinjiniya giredhi thermoplastics uye simbi muCNC machining, zvikamu zvine yakanaka kupedzisa uye yakasimba kwazvo.
Zvakaipa:CNC machining inogona kuva nezvimwe zvisingakwanisi geometric uye dzimwe nguva zvinodhura kuita basa iri mumba kupfuura 3D kudhinda maitiro. Kugaya nibbles dzimwe nguva kunogona kuoma nekuti maitiro acho ari kubvisa zvinhu kwete kuwedzera.
4. Kuumba jekiseni
Rapid jekiseni moldinginoshanda nekubaya thermoplastic resin muforoma uye chinoita kuti nzira yacho 'ikurumidze' itekinoroji inoshandiswa kugadzira mold, iyo inowanzogadzirwa kubva kualuminium kwete simbi yechinyakare inoshandiswa kugadzira mold. Zvikamu zvakaumbwa zvakasimba uye zvine nzvimbo yakanaka yekupedzisa. Iyi zvakare indasitiri yakajairwa kugadzirwa kwezvikamu zvepurasitiki, saka kune mabhenefiti ezvakanakira prototyping mune imwechete maitiro kana mamiriro achibvumidza. Anenge chero einjiniya giredhi epurasitiki kana yemvura silicone rubha (LSR) inogona kushandiswa, saka vagadziri havaganhurwe nezvinhu zvinoshandiswa mukuita prototyping.
Zvakanakira:Zvikamu zvakaumbwa zvakagadzirwa kubva mumhando yeinjiniya giredhi zvinhu zvine yakanakisa kupedzisa kwepamusoro ndiyo yakanakisa kufanotaura kwekugadzira padanho rekugadzira.
Zvakaipa:Mari yekutanga yekushandisa yakabatana nekukurumidza jekiseni kuumba haiitike mune mamwe maitiro ekuwedzera kana CNC machining. Naizvozvo, kazhinji, zvine musoro kuita denderedzwa rimwechete kana maviri ekukurumidza prototyping (kubvisa kana kuwedzera) kutarisa kukwana uye kushanda usati waenda kune jekiseni kuumba.
