Nhanganyaya ye 3D kudhinda:
Chii chinonzi 3D kudhinda?
3D kudhinda tekinoroji yekuwedzera inoshandiswa kugadzira zvikamu.Iyo 'inowedzera' pakuti haidi chivharo chezvinhu kana mold kugadzira zvinhu zvenyama, inongorongedza uye kusanganisa zvidimbu zvezvinhu.Iyo inokurumidza kukurumidza, ine yakaderera yakagadziriswa mitengo yekuseta, uye inogona kugadzira yakanyanya kuomarara geometri pane 'chinyakare' matekinoroji, ine inogara ichiwedzera rondedzero yezvinhu.Inoshandiswa zvakanyanya muinjiniya indasitiri, kunyanya ye prototyping uye kugadzira akareruka geometries.
3D kudhinda uye nekukurumidza prototyping
'Rapid prototyping' mumwe mutsara unomboshandiswa kureva 3D printing technologies.Izvi zvakadzokera kumashure ekutanga nhoroondo ye3D kudhinda apo tekinoroji yakatanga kubuda.Mumakore ekuma1980, pakatanga kugadzirwa michina yekudhinda ye3D, yakanzi inokurumidza prototyping matekinoroji nekuti kare ikako tekinoroji yaingokodzera maprototypes, kwete zvikamu zvekugadzira.
Mumakore achangopfuura, 3D kudhinda kwakakura kuita mhinduro yakanaka kune akawanda marudzi ezvikamu zvekugadzira, uye mamwe matekinoroji ekugadzira (senge CNC machining) ave akachipa uye anowanikwa nyore kune prototyping.Saka nepo vamwe vanhu vachiri kushandisa 'rapid prototyping' kureva kudhinda kwe 3D, mutsara uyu uri kushanduka kureva marudzi ese ekukurumidza kwazvo prototyping.
Mhando dzakasiyana dze 3D kudhinda
3D printers inogona kuiswa mune imwe yemhando dzinoverengeka dzemaitiro:
Vat Polymerization: yemvura photopolymer inorapwa nechiedza
Material Extrusion: yakanyungudutswa thermoplastic inoiswa kuburikidza neinopisa nozzle
Powder Bed Fusion: poda zvimedu zvinosanganiswa nepamusoro-simba sosi
Material Jetting: madonhwe emvura photosensitive fusing agent anoiswa pamubhedha wehupfu uye anoporeswa nechiedza.
Binder Jetting: madonhwe emvura anosunga ajenti anoiswa pamubhedha wezvigadzirwa zvegranulated, izvo zvinozoiswa pamwechete.
Direct Energy Deposition: simbi yakanyungudutswa panguva imwe chete yakaiswa uye yakasanganiswa
Sheet Lamination: mapepa ega ega ezvinyorwa anochekwa kuti aite uye akachekwa pamwe chete
