3D-aidhinda kuti simbi. Gadzira nyaya simbi

3D-wokudhinda ichaongororwa kupfuura akaoma rwokugadzirwa budiriro uye imwe nzvimbo inokosha chirungiso mukugadzira. Nemhaka-dimensional matatu vaidhinda mikana itsva sectors dzose upfumi. Zvinofungidzirwa kuti mune ramangwana vanogona kunyange dzevamwe tsika modes okuwana (nokuchengetedza, vachikanda, etc.). Munyaya ino tichakurukura zvinodzidziswa 3D-wokudhinda nesimbi uye ayo chikuru rwokugadzira.

Chii 3D-aidhinda kuti simbi

Ava michina chaiyo inobvumira simbi zvinhu, kana kuti jasi rakapera zvigadzirwa. aidhinda akadaro "chinokura" wenyama chinhu mune akaturikidzana. Kureva, kutanga pamusoro kombiyuta iri ouinjiniya ezvinhu pave rakapotsa muenzaniso iri kukura matatu, yakakamurwa nokuda digitaalinen akaturikidzana. Pashure kutanga-up of chinhu muna 3D-kudhindwa musoro aidhinda anotanga kuzvimbandidzira nemvura simbi , kana upfu iri vachidurura ari anodhinda pakakwirira, achiumba zvakaturikidzaniswa wokutanga. The muchina zvino zvinoshanda mugove wechipiri simbi uye zvichingodaro.

3D-aidhinda kuti simbi unokubvumira kuumba guru siyana mishonga uye, aonga yazvino, aigona kuva makwikwi kuti dzenhoroondo nzira kugadzirwa simbi.

Kuti iwe unogona kudhinda pamusoro 3D-vaidhinda?

kuvamba Iri zvakasikwa aidhinda zvinogona kushandisa zvose nyanzvi uye vanhuwo iyi. Metalloprintery ringashandiswa kugadzira non-mureza zvivako, zvemaziso zvikamu, zvishongo. Ivo vanobvumira kuti kusika simbi zvigadzirwa, kutevedzera ruoko-ndokugadzira. Uye haatarisiri mamwe mano uye zvigadziriswe.

Industrial 3D-aidhinda kuti simbi kunogona kunyange kudhinda chitundumuseremusere injini. Saka zvichava zvokuti hapana kusiyana zvigadzirwa chinoitwa nzira chetsika. Saka, metalloprinter runoita murume ano kusika zvimwe zvinhu.

3D-okudhindira michina kuti simbi

Pari, kugadzirwa simbi zvigadzirwa mune ruzivo zviviri: Laser neingi-ndege rokudhinda. Zvinosanganisira zvishoma nezvishoma uye yakarurama lamination nesimbi, apo vanofanira kuti pamuviri nhamba. Panguva iyoyowo, mainjiniya vakava nzira wandei kurimwa.

Inkjet Kudhinda matatu-dimensional

Gadzira nesimbi nyaya ndege yokudhinda nderimwe mukuru nzira chirungiso mukugadzira. Kunoitawo kushandiswa nesimbi sezvo consumables yakanakisisa. Asi ruzivo urwu rinoshanda chete kune chine muenzaniso. Chokwadi chokuti 3D-inkjet aidhinda unokubvumira kudhinda zvinhu chero zvinhu inogona kupatsanurwa kuva upfu. Panguva yokudhinda, wakatemerwa mbishi zvinhu unesungano Polymers. Nokuda ichi kwesayenzi zviri apera zvigadzirwa hazvigoni kunzi zvachose simbi.

Uyezve, zvinoita kutendeutsa akagamuchira rinoumba-metal yokutevedzera. Kushandisa ichi chafariz pisa kana akanyauka kuti polymer uye sintering ari weupfu simbi. Kwakadaro simbi zvigadzirwa haasi simba, sezvo vane porous yakarongeka. Add simba anogona kuitwa impregnation imwe zvesimbi. Somuenzaniso, imwe simbi chinhu ruchasimba kana soka nendarira.

Nzira iyi rakasikwa zvigadzirwa dzinowanzotsigi- kushandiswa chirangaridzo uye kwezvishongo indasitiri.

lamination nzira

3D-anodhinda lamination muitiro kunosanganisira kushandisa kuchikuva marata machira, kuumbwa kuti Laser kana zvokuimba nokuveza, uye gluing kuti vawane-dimensional matatu womuenzaniso. Nzira iyi inobvumira kuti kushandisa somunhu consumable zvinhu, kunyange simbi foil. Laminated zvinhu havana simba simbi, sezvo kuvimbika kwavo kunobva gluing machira ane connectability.

Kunakisa zvigadzirwa izvi kuonekwa vashoma shoma mari uye Kugona zvakasiyana siyana zvinhu akafanana kune zvose-metal zvigadzirwa. The inonyanya lamination yokudhinda inoshandiswa kusika Layouts.

Layered akakonzera kubatana kwe

nzira iyi 3D-Kudhinda kunobva pakushandisa chiwanikwa zvinhu. Extruders zvinowanikwa aidhinda hakusi kugona kumira dzakakwirira tembiricha. Naizvozvo, kuti asike zvinhu simbi yakachena uye alloys kwakaoma zvisingaiti. Saka, Developers wenhumbi vakatanga kubudisa chaiyo ematongerwo zvinhu. Muenzaniso zvinogadzirisa yakadaro zvinhu zvinosanganisira thermoplastic uye ndarira upfu.

The aidhinda iri mhando rinodhindira simbi zvinhu, izvo chitarisiko indistinguishable inobva zvose-metal zvigadzirwa. Asi ehupfumi zvinhu zvakadaro chaiko yekudyidzana kuipa. Naizvozvo, akakonzera kubatana kwe layering rinoshandiswa chete pakusikwa yokutevedzera, matkamuistoja, nechomukati zvinhu. Zvino mainjiniya vari kutsvaka maindasitiri nharaunda kwazvinobvumirwa kushandisa ruzivo urwu kubereka. Saka, mumwe thermoplastic pamwe esimbi filler rinogona kushandiswa kudhinda zvemagetsi redunhu mapuranga.

Vanosarudza Laser sintering uye zvakananga

Kusarudza Laser sintering nesimbi anogona kushanda kwete chete rakasimba zvinhu, asiwo thermoplastic. Pane anowanikwa pakusikwa-dimensional matatu zvinhu achishandisa Laser mano kuburikidza sintering upfu simbi. Kazhinji, kuderedza simba Laser emitters ari esimbi fusible zvinhu rinoshandisirwa pamusoro unhani. Muzviitiko zvakadaro, nokuti inowedzera simba rapera chigadzirwa zvinoda zvimwe sintering uye impregnation dzavo simbi.

A kusiyana of zvinorondedzerwa nzira iri zvakananga chesimbi Laser sintering. Michina iyi nezvezvandaifanira uchishanda yakaisvonaka simbi upfu mhando. Kuti vawane chinangwa ichi, pane chinokosha rakanamwa makamuri akazara pamusoro 3D-vaidhinda ane inert gasi. Uyewo, muchina wokudhinda anoshandisa consumables kudziyisa kuti tembiricha panguva iyo inonyunguduka, asi vasati chipatapata. Izvi zvinoderedza nguva kudhinda uye tichengetedze simba Laser enyika.

Print nokuda Laser sintering kunoitika akaturikidzana. On basa kuchikuva muchina kunokonzera nhete rukoko pamusoro preheated upfu ane nezvimedu vari sintered pakati pachavo uye yapfuura rukoko. The Laser danda riri dzichichinja mirayiridzo yaro nokushandisa kwegadziriro magirazi.

Laser sintering zvinoita kuti pave zvivako zvakaoma pasina zvimwe zvitsigiso. Saka, ano ichi chinoshandiswa kuumba zvakarurama zvikamu aisada hake unozotevera machine, uyewo kugadzirwa zvokufonongonwa yemashoko kunzwisisa zvokuti hazvibviri kuita munhu kwakajairika Kudzingwa.

Laser sintering kunoita kushanda pamwe simbi, nickel alloys, titanium, simbi dzinokosha uye zvakafanana. D.

Vanosarudza Laser uye Erekitironi danda utsotso simbi

Kunyange zvazvo muenzaniso yaunganidzwa zvesimbi Laser-sintering, vane high quality, vane shoma kushanda. The porous maumbirwo apera zvinhu kunoderedza simba ravo. zvigadzirwa kwakadaro kukodzera kuti maindasitiri kushandiswa, uye vakawanda vari akashandisa kusika mockups uye prototypes. Nokuti kugadzirwa Zvinokosha zvakaisvonaka uye husingakwanisi kushushikana yokutevedzera, mainjiniya vakachinja mabikirwo zvakananga Laser sintering Laser utsotso nzira. It chakavakirwa kupisa pakurapa simbi upfu kuwana homogeneous chinhu simba. Zvinhu rakadhindwa nenzira iyi yorega zvakasiyana zvemaziso uye panyama zvivako zviri analogues zvinoberekwa nemakwenzi.

In kufanana zvemichina ichi rinoshandiswa Erekitironi-danda utsotso. Kunoitawo kuti kusika zvinhu pamwe chete zvakarurama uye kwemupfungwa, asi kune zvimwe zvakwakanakira. Saka, 3D-aidhinda iyi mhando nesimbi pachinzvimbo electromechanical girazi gadziriro vakapakata Erekitironi pfuti. Izvi zvinoita muchina kushanda pachidiwa yakakwirira aimhanya, izvo anowedzera negoho mutoo pasina chinokosha matambudziko. Michina kwakadaro yakanaka nzira kune zvetsika maindasitiri kugadzirwa kuti kushandisa mamwe midziyo (muchoto uye kuumbwa zvitarisiko).

Printer Laser uye Erekitironi danda utsotso dzinowanzotsigi- kushandiswa pakugadzira zvikamu ndege injini uye gasi turbines, vachibatsira prostheses.

Direct Laser chirungiso kuvaka

3D-aidhinda nokuda zvakananga Laser simbi kuvaka inoshandiswa kugadzirisa rakapera zvigadzirwa. Mabikirwo muchina akadaro ndiye musimboti wenyika deposition of simbi upfu nezvimedu pamusoro dzaparadzwa zvikamu chinhu dzavo utsotso Laser. Nzira iyi kunoratidzwa yakatetepa specialization uye rinoshandiswa chete maindasitiri zvinangwa.

Akadhindwa aidhinda musoro ichi mhando inodedera mu ndege matatu uye kutenderera pamusoro wehunyambiri akabatana. Saka, kunoshanda chero akachinjikana.

michina yakadaro dzinoshandiswa yokugadzirisa zvakaoma michina uye makuru kadikidiki zvigadzirwa. Somuenzaniso, kuti vagadziridze injini ndege.

Mari 3D-vaidhinda kuti simbi

On kumusika nhasi zvakawanda michina vachibvumira kusika-dimensional matatu simbi zvinhu. mutengo wavo kunobva zvizivikanwe uye zvokudhinda rwokugadzira. Saka, maindasitiri 3D-aidhinda kushanda simbi, iro raunogona kupirinda injini, mutengo ezviuru zvemadhora. More inokwanisika michina inogona kutengwa isingadhuri zvikuru, asi kunaka zvigadzirwa kukazonyanyisa. Kuti vagadzirise dambudziko iri, mainjiniya vari kugadzira 3D-aidhinda nokuda simbi, mitengo ichazovapo yakaderera zvikuru kana zvakazara vakagadzirira kushandisa.
