Iyo Yechokwadi Ndeipi Iyo 3D Yekudhinda Zvikamu?

1. Chii chinonzi kururama

Muchidimbu, kurongeka ndiko kuswederana kwezvikamu zvinonyatso gadzirwa kuti zvienderane nekukura kwemagadzirirwo ekutanga uye chimiro, chinova chiyero. Sezvo maprinta e3D achivimba nezvikamu zvakawanda zvinofamba, maitiro aya haambofa akaburitsa 100% chaiyo chikamu (kana chero maitiro ekugadzira). Kururama kunowanzo kuratidzwa muzvikamu zvezana kana mamirimita, senge ± 1% kana ± 0.5 mm.

2. Kururama kweakasiyana 3D kudhinda matekinoroji

siyana 3D kudhindwa matekinoroji ane huchokwadi hwakasiyana.

FDM

Fused deposition parizvino ndiyo inonyanya kufarirwa tekinoroji yekudhinda ye3D (nekuti ndiyo inotengeka zvakanyanya), uye nhamba huru yematafura parizvino anoshandisa tekinoroji iyi.

Kurongeka kwedesktop FDM 3D printer inenge ± 0.5 mm. Kurongeka kwemaindasitiri eFDM maprinta angangoita ± 0.2 mm.

SLA, DLP

Photopolymerization kudhinda matekinoroji akadai seSLA neDLP anoshandisa mwenje masosi senge lasers kana mapurojekita kurapa photosensitive resins. Kurongeka kunenge ± 0.1 mm. Kurongeka kwenyanzvi resin 3D printer inenge ± 0.01 mm.

SLS

Kusarudza laser sintering, iyo inoshandisa laser kupinza hupfu zvidimbu, kazhinji hupfu hwenylon. Kurongeka kunenge ± 0.3 mm.

SLM

Metal poda fusion maitiro akadai seSLM anoshandisa lasers kunyungudusa kana sinter simbi poda zvimedu zvine chokwadi che ± 0.1 mm.

Jet yezvinhu

Kunyangwe zvisiri zvakajairika sematekinoroji akafanana, ejection yezvinhu yakanyatsojeka nekuti haidi kudziyisa, izvo zvinogona kukonzera deformation, senge warping. Kurongeka kunenge ± 0.05 mm.

3.Zvimwe zvinhu zvinokanganisa dimensional accuracy

Rudzi rwe 3D kudhindwa tekinoroji haisiriyo yega chinhu chinotarisa kurongeka kwe3D kudhinda. Zvishandiso, chikamu dhizaini uye kudhinda paramita zvakare zvine chekuita nekurongeka.

Printer quality: Pane mukaha mukuru pakati pemhando yemaprinta epamusoro-soro nemaprinta ekupinda-chikamu. Desktop-level 3D maprinta anowanzo kudhura zviuru zvishoma, uye maindasitiri-level 3D maprinta anotanga kubva kumakumi ezviuru. Musiyano muzvikamu zvemagetsi senge stepper motors inoshandiswa pamitengo yakasiyana inogona kufungidzira.

Chikamu dhizaini: Kunyangwe akanakisa 3D maprinta haakwanise kunyatso dhinda 3D zvikamu zvisina kugadzirwa. Semuenzaniso, nzvimbo yacho yakakura kwazvo, kureba kwakareba, uye hakuna tsigiro.

Zvishandiso: Zvimwe zvinhu zviri nyore kuprinda pane zvimwe, saka zviri nyore kugadzira zvikamu chaizvo. Zvisiri-zvakajairwa zvinhu (sezvinochinjika PLA, alloys ane simbi dzinokosha) anowanzo pira kudhinda mukutsinhana neayo mabhenefiti akasiyana.

Kudhinda parameters: Mushandisi anogona kugadzirisa maparamendi ekudhinda zvichienderana nekuseta kweprinta, senge layer urefu, kumhanya kwekudhinda, kuzadza zvinhu, nezvimwewo Somuenzaniso, kukurumidza kukurumidza kudhinda, kuderera kwekururama.

Chechina, maitiro ekuvandudza 3D kudhinda chaiko

Dzima kana kurerutsa zvinhu zvakaoma paunenge uchigadzira zvikamu.

Tumira kunze iyo STL faira padanho repamusoro rinogoneka.

Gadzirisa iyo 3D printer nguva nenguva kana pamberi peakakosha mabasa ekudhinda.

Shandisa zvinotsigira kudzikamisa zvinhu paunenge uchidhinda, uye chenjera paunenge uchibvisa zvinotsigira kudzivirira zvikamu zvinokuvadza kana kushandura mativi azvo ekupedzisira.

Shandisa mubhedha unopisa wakadhindwa (FDM) kana kamuri inopisa (SLS / metal) kuchengetedza kupisa kwezvikamu kunoenderana kuderedza deformation.

Kana pasina nguva inodiwa, kuderedza kumhanya kwekudhinda zvakanyanya sezvinobvira.

Batanidza kuchinyorwa ichi: Iyo Yechokwadi Ndeipi Iyo 3D Yekudhinda Zvikamu?

Dzokorora Chirevo: Kana pasina mirairo yakakosha, zvinyorwa zvese zviri pasaiti ino ndezvepakutanga. Ndokumbira uratidze kwakabva kudhindazve: https://www.cncmachiningptj.com/, thanks!
