3D-chosindikizira cha chitsulo. Kupanga nkhani zitsulo

3D-atolankhani akuganiza kwambiri zovuta kuzimvetsa zamakono kupindula ndi malo ofunika a opanga zowonjezera. Chifukwa cha osindikiza mabuku atatu azithunzi omwe tikunena mwayi m'magulu onse a chuma. Iwo ankakhulupirira kuti m'tsogolo akhoza amalanda mwanjira chikhalidwe kupanga (kulipira akuponya, etc.). M'nkhaniyi tiona zimene zitsulo 3D-atolankhani ndi luso waukulu.

Kodi 3D-chosindikizira cha chitsulo

Awa ndi wapadera makina amene amalola zitsulo zinthu, kapena kuti chovala yomalizidwa mankhwala. Chotero osindikizira "limakula" chinthu thupi mu zigawo. Ndiko kuti, poyamba pa kompyuta dongosolo zomangamanga amalenga chitsanzo pafupifupi m'mbali zitatu, anagawa ndi zigawo yadigito. Pambuyo pa-kwa chinthu 3D-yosindikiza mutu wa chosindikizira akuyamba Finyani zitsulo madzi kapena ufa mudzachotsedwa mu nsanja kusindikiza, n'kupanga wosanjikiza choyamba. makina Kenako amagwiritsa ntchito gawo lachiwiri la zitsulo ndi zina zotero.

3D-mabuku a pa zitsulo limakupatsani kulenga osiyanasiyana lalikulu la mankhwala, chifukwa cha luso lamakono, kodi ndi mpikisano kuti njira chakale kupanga zitsulo.

Kuti mungathe kusindikiza za 3D-osindikiza?

Kutulukira Izi ndi chosindikizira chilengedwe zomwe angagwiritse ntchito akatswiri komanso okonda wamba. Metalloprintery akhoza kugwiritsidwa ntchito popanga zipangizo sanali muyezo, makina mbali, zodzikongoletsera. Iwo amakulolani kupanga zitsulo, kutsanzira dzanja wopeka. Ndipo sikutanthauza zipangizo zina ndi njira.

Industrial 3D-mabuku a pa zitsulo ngakhale kusindikiza injini roketi. Choncho adzakhala pafupifupi palibe wosiyana mankhwala opangidwa ndi njira za makolo. Choncho, metalloprinter kumapangitsa munthu ano kulenga zinthu zonse.

3D-makina luso chifukwa zitsulo

Pakali pano, kupanga katundu zitsulo mu njira zamakono awiri: laser ndi inki-ndege yosindikiza. Zikukhudza pang'onopang'ono ndi zolondola lamination zitsulo, umene ayenera pakati chithunzi. Pa nthawi yomweyo, akatswiri apanga njira zosiyanasiyana kulima.

Inkjet yosindikiza atatu azithunzi omwe tikunena

Kupanga zitsulo nkhani ndege kusindikiza ndi imodzi mwa njira wamkulu wa opanga zowonjezera. Timatha mungagwiritsire ntchito zitsulo consumables. Koma njira imeneyi ntchito kokha pa nkhani ya chitsanzo gulu. chakuti chosindikizira 3D-inkjet limakupatsani kusindikiza zinthu zakuthupi aliyense amene angathe kukonzedwa mu ufa. Pa kusindikiza akanadulidwa zopangira kumayambitsa ma polima. Chifukwa mbali iyi sayansi mankhwala yomalizidwa sangatengedwe kukhala zitsulo kwathunthu.

Komanso, n'zotheka kuti atembenuke analandira gulu zitsulo zitsanzo. Kutsatira lamoto izi matenthedwe kapena kusungunula wa polima ndi sintering zitsulo ufa. mankhwala ameneŵa zitsulo ndi mphamvu, chifukwa ndi dongosolo porous. Kuwonjezera mphamvu chingapezeke mwa impregnation zitsulo wina. Mwachitsanzo, zitsulo chinthu adzakhala wamphamvu ngati zilowerere zamkuwa.

njira kulenga mankhwala zimagwiritsa ntchito mu kachikumbutso ndi miyala yamtengo wapatali makampani.

njira lamination

3D zilembo lamination ndondomeko tiyenera kugwiritsa ntchito ku nsanja wopyapyala zitsulo, kupangidwa kwa laser kapena kudula makina, ndipo gluing apezere atatu azithunzi omwe tikunena chitsanzo. Njira imeneyi zimathandiza inu ntchito monga chuma consumable, ngakhale zitsulo zojambulazo. zinthu Laminated mulibe mphamvu ya chitsulo, popeza okhulupirika zochokera gluing mapepala connectability.

Ubwino wa njira imeneyi akuti ndi mtengo wotsika ndi luso kulenga zosiyanasiyana zinthu zofanana ndi mapulogalamu onse zitsulo. Ambiri lamination kusindikiza ntchito kulenga masanjidwe.

magawo kusakaniza

Njira imeneyi 3D-yosindikiza zachokera ntchito zipangizo aloyi. Extruders akupezeka chosindikizira sangathe kupirira kutentha. Choncho, polenga zinthu zitsulo koyera ndi kasakaniza wazitsulo kuli kovuta. Choncho, kutukula katundu anayamba kutulutsa katundu wapadera gulu. Chitsanzo cha njira zoterozo ndi chuma ongokhala thermoplastic ndi mkuwa ufa.

The chosindikizira cha ichi mtundu zipsera zitsulo zinthu, zomwe maonekedwe osiyana ndi mankhwala ndi zonse zitsulo. Koma thupi katundu zinthu zimenezi kwambiri poipa. Choncho, kusakaniza layering ntchito yekha kwa chilengedwe cha zitsanzo, alendo, zinthu mkati. Tsopano akatswiri akufunafuna malo mafakitale angalalikire kutsatira njira imeneyi kubala. Choncho, thermoplastic ndi filler zachitsulo angagwiritsidwe ntchito kusindikiza matabwa pakompyuta dera.

Kusankha laser sintering ndi mwachindunji

Kusankha laser sintering zitsulo akhoza ntchito osati ndi chuma cholimba, komanso ndi thermoplastic. Pali amapezeka chilengedwe cha zinthu atatu azithunzi omwe tikunena ndi njira zamakono laser ndi sintering zitsulo ufa. Nthawi zambiri, kuchepetsa mphamvu ya emitters laser pa zinthu zachitsulo fusible umagwiritsidwa ntchito pa ❖ kuyanika. Zikatero, chifukwa kuwonjezera mphamvu ya chotsirizidwa amafuna owonjezera sintering ndi impregnation awo zitsulo.

inanso njira anafotokoza ndi mwachindunji zitsulo laser sintering. Njira imeneyi lolunjika pa ntchito ndi oyera mtundu zitsulo ufa. Kukwaniritsa cholinga ichi, pali wapadera zipinda womata wodzazidwa a 3D-osindikiza ndi mpweya inert. Komanso, makina osindikizira amagwiritsa consumables Kutentha ndi kutentha pa chimene chimasungunula, koma osati koma pachimake. Izi amachepetsa nthawi yosindikiza ndi kupulumutsa pa machitidwe mphamvu laser.

Sindikizani ndi laser sintering chikuchitika mu zigawo. Pa ntchito nsanja makina amachititsa wosanjikiza woonda wa ufa preheated amene particles ali sintered pakati pawo ndi wosanjikiza m'mbuyomu. The laser mtengo zikusintha malangizo ake pogwiritsa ntchito dongosolo la kalirole.

Laser sintering limachititsa kulenga nyumba zovuta popanda zogwiriziza zina. Choncho njira imeneyi ntchito kulenga mbali mwatsatanetsatane osati zofuna Machining wotsatira, komanso kupanga zitsanzo olimba a zovuta kumvetsa zoterozo kuti n'zosatheka kuti achite kuponyera ochiritsira.

Laser sintering amalola ntchito ndi chitsulo, faifi tambala kasakaniza wazitsulo, titaniyamu, zitsulo zamtengo wapatali ndi monga D..

Kusankha laser ndi elekitironi mtengo limatsogolera zitsulo

Ngakhale chitsanzo akamagwira zitsulo laser-sintering, ndi a high quality, iwo ndi ntchito yochepa. Kapangidwe porous zinthu yomalizidwa amachepetsa mphamvu. mankhwala amenewa ndi zosafunika ntchito mafakitale, ndipo ambiri ntchito kulenga mockups ndi prototypes. Kwa kupanga cholimba ndi kugonjetsedwa ndi zitsanzo nkhawa, akatswiri zasintha luso mwachindunji laser sintering laser limatsogolera njira. Bukuli lili ndi amphamvu kutentha mankhwala a ufa zitsulo kupeza chinthu homogeneous. Zinthu kusindikizidwa njira imeneyi si kwenikweni amasiyana katundu makina ndi thupi la analogues ndi opangidwa ndi njira za makolo.

Limodzi ndi njira imeneyi ndi ntchito zinthu zosiyanasiyana za mtengo kusungunuka. Iwo limakupatsani kulenga zinthu ndi Kulondola ndi kusamvana, koma lili ndi ubwino wake. Choncho, 3D-chosindikizira cha mtundu wa zitsulo m'malo machitidwe electromechanical galasi okonzeka ndi mfuti elekitironi. Zimenezi zimathandiza makina ntchito pa liwiro ndi mkulu, amene kumawonjezera zokolola za ndondomeko popanda mavuto kwambiri. luso monga kwambiri njira kwa kupanga miyambo mafakitale kuti ntchito zida zina (uvuni ndi akalumikidzidwa kuumbidwa).

Printer laser ndi elekitironi mtengo limatsogolera zimagwiritsa ntchito yopanga mabuku a injini ndege ndi turbines gasi, mafupa ziwalo.

Direct laser zowonjezera yomanga

3D-chosindikizira kwa laser mwachindunji zitsulo kumanga ntchito kukonza yomalizidwa mankhwala. The luso ngati makina ndi mfundo ya mafunsidwe a particles zitsulo ufa mbali zowonongeka wa chinthu ndi kusungunuka laser awo. Njira imeneyi amakhala ndi specialization yopapatiza ndi ntchito yokhayo yotumikira zolinga mafakitale.

Kusindikizidwa chosindikizira mutu wa mtundu uwu ndi anasamukira ku ndege atatu ndipo onsewo za olamulira choimirira. Choncho, ntchito mwanjila iliyonse.

makina amenewa ntchito yokonza makina zovuta ndi lalikulu-kakulidwe mankhwala. Mwachitsanzo, zokonzera injini ndege.

Mtengo wa 3D-osindikiza chifukwa zitsulo

Masiku ano, msika ndi osiyanasiyana makina, kulola kulenga atatu azithunzi omwe tikunena zitsulo zinthu. phindu zimadalira mtundu ndi kusindikiza luso. Choncho, mafakitale 3D-chosindikizira ntchito ndi chitsulo, limene mungathe kusindikiza injini, mtengo zikwizikwi dollars. makina More angakwanitse zikhoza kugulidwa mtengo kwambiri, koma amasokoneza zingaipe kwambiri. Kuti athetse vutoli, akatswiri akupanga 3D-mabuku a pa zitsulo, mtengo wa amene adzakhala m'munsi pamene kwathunthu okonzekera ntchito.
