Kupanga Zowonjezera: Kusindikiza kwa 3D mu Circular Economy

Mawu Oyamba

Mawu odziwika bwino akuti, “Yang’anirani dziko ndipo lidzakuyang’anirani, wonongani dzikolo ndipo lidzakuwonongani” likusonyeza kufunika kwa malo athu. Kuti tisunge ndi kuteteza chilengedwe chathu kuti chisawonongeke, tiyenera kuyang'ana kwambiri pakukulitsa kukhazikika. Titha kuchita izi pogwiritsa ntchito chuma chozungulira pogwiritsa ntchito njira zopangira zowonjezera (AM) panjira zachizolowezi zopanga (CM) (Velenturf ndi Purnell). AM - yomwe imadziwika kuti kusindikiza kwa 3D - imachepetsa zinyalala, imagwiritsa ntchito zinthu zachilengedwe, komanso imachepetsa kugwiritsa ntchito mphamvu, zomwe zimapangitsa kuti ikhale chinsinsi cha tsogolo losasunthika.

Amachepetsa Zinyalala ndi Kuipitsa

Zipangizo zocheperako zimawonongeka ndipo kuipitsa kochepa kumapangidwa tikamagwiritsa ntchito AM pa CM. Malingana ndi aphunzitsi a MR Khosravani ndi T. Reinicke a yunivesite ya Siegen, "[AM] amalola kutaya pang'ono popanga zinthu monga zigawo zonse za zitsanzo, ma prototypes, zida, nkhungu, ndi mankhwala omaliza amapangidwa m'njira imodzi" (Khosravani ndi Reinicke). Ndi chilichonse chopangidwa wosanjikiza ndi wosanjikiza kuchokera pansi mpaka pamwamba, makina osindikizira a 3D amangogwiritsa ntchito zofunikira pagawo lomaliza ndi zida zazing'ono zothandizira. Mosiyana ndi zopanga zachikhalidwe, zinthu zimapangidwa popanda kufunikira kusonkhana mu AM. Izi zikutanthauza kuti mpweya wowonjezera kutentha womwe umatulutsidwa panthawi yamayendedwe udzapewedwa, ndikuchepetsa kuipitsidwa.

Kupulumutsa Mphamvu

Kupatula kuchepetsa zinyalala komanso kugwiritsa ntchito zinthu zoteteza chilengedwe, AM ndiyothandiza kwambiri m'mafakitale. AM imakulitsa mphamvu zamagetsi ndikuchepetsa kugwiritsa ntchito mafuta panthawi yopanga (Javaid et al.).

Kuphatikiza apo, a White House adalengezanso kuti "Chifukwa matekinoloje owonjezera amamanga kuchokera pansi m'malo mochotsa zinthu zomwe zidachotsedwa, matekinolojewa amatha kutsitsa mtengo wazinthu ndi 90 peresenti ndikuchepetsa kugwiritsa ntchito mphamvu pakati" (White House). Ngati mafakitale onse omwe angathe kusintha zomwe akupanga pano ndi njira ya AM atatero, tingakhale pafupi kwambiri kuti tikwaniritse.

Mapeto

Kugwira ntchito bwino kwa chilengedwe ndiye mwala wapangodya wa kukhazikika, ndipo kuchepetsa kugwiritsa ntchito mphamvu ndi kuwononga zinyalala kungayambitse kuyimitsidwa kwakukulu kwa kutentha kwa dziko (Javaid et al.). Ngati nthawi yochulukirapo ndi zothandizira zimayikidwa pakufufuza ndi chitukuko cha AM, titha kukwanitsa kupanga chuma chozungulira.
