Metal 3D Kudhinda

Metal 3D kudhinda inzira yekugadzira yekugadzira iyo inoshandisa zvidimbu zvezvinhu kugadzira chikamu chakasimba. Iyo nzira inoderedza marara nekushandisa chete zvinhu zvinodiwa kugadzira chikamu. Inopawo rusununguko rwekugadzira nekubvumidza yakaoma geometries uye topologically optimized chikamu dhizaini. Inogona kushandiswa kugadzira zvigadzirwa zvisingaremi, zvakasimba. Uye zvakare, simbi ye3D kudhinda inogona kubatsira kubatanidza magungano akaoma kuita chikamu chimwe chete.

zvinhu

Kana iwe uchitsvaga yakawedzera kusimba yepurojekiti yako yekudhinda ye3D, funga kushandisa alloy yesimbi. Kubatsira kwechinyorwa ichi isimba rayo, huremu hwakaderera, uye kuchinjika mumashure-kugadzirisa. Ichi chinyorwa chinokubvumira kuti ugadzire mamodheru ane akaomesesa maficha uye yakaoma geometry. Nekudaro, zvakakosha kuti usarudze dhizaini yakakodzera yechishandiso chako. Izvi zvinosanganisira kusarudza kukora kwemadziro.

Nepo kune akasiyana simbi e3D kudhinda, kune akati wandei marudzi ealloys anopa akasiyana mabhenefiti. Semuenzaniso, kune "superalloys" inopa musanganiswa wekupisa kupisa, kusimba kwepamusoro, uye kushorwa nekuora. Aya maalloys anoshandiswa mune akawanda epamusoro-kuita maapplication. Cobalt Chrome uye Inconel maviri alloys akadaro.

urongwa

Metal 3D kudhinda inzira inobvumira kugadzirwa kwezvikamu zvakaoma zvakagadzirwa nesimbi. Kuenzaniswa neyakajairwa nzira dzekugadzira, inogona kuderedza tooling nguva uye mutengo. Nekuda kwekuchinjika kwayo uye mashandiro emuchina, simbi 3D kudhinda kune akawanda maapplication. Kushandiswa kwakajairika kunosanganisira kunyatsoshanda prototyping, maturusi ekugadzira, zvinopisa kupisa, uye dzimba.

Metal 3D kudhinda inzira inoshandisa laser kunyungudusa akateedzana akaturikidzana ehupfu simbi. Mhedzisiro yacho chikamu chetatu-mativi icho chine 99% chakakora asi chakanyanya kujeka. Iyo zvakare inobvumira simbi 3D yakadhindwa zvikamu kuti ibatanidze zvakaomesesa zvemukati maficha uye geometries ine shoma zvinhu tsvina.

Applications

Metal 3D kudhinda inzira ine simba yekugadzira iyo inogona kuburitsa zvikamu zvingave zvisingaite kugadzira. Iyo inokwanisa kugadzira zvikamu zvakaomesesa, zvinosanganisira makomba akaomarara uye geometries. Iyi tekinoroji inogona zvakare kushandiswa kugadzira maturusi ekugadzira ezvakajairwa kugadzira maitiro. Munzvimbo yeaerospace uye mechaniki engineering minda, simbi 3D kudhinda ine yakafara maapplication.

Kuita kwesimbi 3D kudhinda kunosanganisira kuvaka chikamu chechikamu ne layer. Kazhinji, imba yekuvaka inozadzwa neinert gasi kuderedza njodzi yeoxidation musimbi. Tevere, hupfu hunoiswa pamusoro pepuratifomu yekuvaka. Zvadaro, laser inoongorora muchinjiko-chikamu chechikamu uye inosanganisa magranules pamwechete kuti iumbe yakasimba layer. Iyi nzira inoenderera mberi kusvika chikamu chapera.

Zvinhu zvinoshandiswa

Metal 3D kudhinda inoshandisa marudzi maviri ezvigadzirwa. Yekutanga iwaya dzesimbi, dzinonyungudutswa nelaser, plasma arc, kana electron beam. Mune yechipiri mhando yesimbi 3D kudhinda, iyo laser inoisa simbi yakananga papuratifomu yekuvaka. Mhando mbiri mbiri dzesimbi 3D kudhinda dzinoshandisa simbi dzakasiyana mune granular fomu, kusanganisira mhangura, simbi isina tsvina, aruminiyamu, uye cobalt chrome.

Mhangura isimbi yakakurumbira yekudhinda kwe3D nekuda kwekupisa kwayo uye magetsi ekufambisa. Nekudaro, mhangura inoratidzira, izvo zvinoita kuti zviome kushandisa matanda elaser ayo anowanzo shandiswa mukudhinda simbi 3D. Nechikonzero ichi, mainjiniya aifanira kukunda akati wandei matambudziko apo 3D kudhinda mhangura. Nekudaro, vaongorori veFraunhofer ILT vakabudirira kugadzira zvikamu zvemhangura zvine hunyoro hwakanyanya uye yakaoma geometries.

nzira

Metal 3D kudhinda inzira yekuvaka simbi zvidimbu uchishandisa 3D printer. Maitirwo acho anosanganisira kuiswa kweupfu hwesimbi muzvidimbu zvitete, zvinozobatanidzwa nebhainda. Iri bhinda rinobva raburitswa kubva mumusoro wakadhinda uye richipararira zvakaenzana pamusoro pesero. Pakupedzisira, zvikamu zvinochinjana zvehupfu yesimbi uye binder fuse pamwe chete, zvichivaka chinhu chinodiwa che3D. Nzira yacho inogona kutora maawa akawanda.

Metal 3D kudhinda ine huwandu hukuru hwezvakanakira, kusanganisira kugona kugadzira yakaoma geometries ine yakakwirira madhigirii erusununguko rwekugadzira. Iko hakuna chikonzero chekukanda mafi kana mold kugadzira chikamu, chinoita kuti maitiro aya ave akanaka kune prototyping uye yakaderera-vhoriyamu yekugadzira inomhanya. Uyezve, maprinta esimbi ari kuwedzera kuve akakurumbira kune makuru-zvimiro. Mamwe maprinta esimbi e3D anogona kudhinda zvikamu zvekusvika pamamita matanhatu pakureba.
