Pali mitundu inayi ikuluikulu ya njira zaKusindikiza kwa 3D, ndipo njira zatsopano nthawi zambiri zimatuluka.Njira iliyonse yowonjezera yowonjezera imagwiritsa ntchito zipangizo zosiyanasiyana kuti apange zigawo zomwe zimakhala ndi zinthu zapadera zomwe zimagwira ntchito bwino pa ntchito zinazake.
1. pali photopolymerization
Kuchepetsa ma polymerization amadzimadzi a photopolymers ochiritsidwa ndi photosensitive polymerization ndi imodzi mwazinthu zoyambirira zopangira zowonjezera.Uv wosanjikiza wolondola pochiritsa wosanjikiza ndi kulimba kwa zigawo zoonda za utomoni wa photosensitive.Njira imeneyi, yotchedwa stereophotography, idagulitsidwa pakati pa zaka za m'ma 1980.Ndi choyambiriraKusindikiza kwa 3Dukadaulo m'malingaliro, magawo a stereolithography amagwiritsidwa ntchito kuyika ndalama pazogwiritsa ntchito monga mawonekedwe oponyera, ma prototypes ndi mitundu yamalingaliro.Ukadaulo wina wodziwika bwino ndikusintha kuwala kwa digito.
2. extrusion zakuthupi
Mtundu wopangira zowonjezera uwu umagawira zinthuzo powotcha mphuno kapena kutulutsa mutu.Mukayala wosanjikiza umodzi, tsikirani kuti mumange nsanja, kapena sunthani mutu wa extrusion mmwamba kuti musindikize wosanjikiza wotsatira pamwamba pa wosanjikiza wapitawo.Zopangirazo nthawi zambiri zimakhala thermoplastic filament, zovulala pa spool ndikusungunuka zikatulutsidwa.Njira yodziwika bwino yogwiritsira ntchito njirayi ndikuyika mosungunuka.Zopangira zowonjezera zamtunduwu zitha kugwiritsidwa ntchito popanga zida, zida zopangira, komanso ma prototypes ogwira ntchito chifukwa chotha kupanga ndi zida wamba za thermoplastic.
3. ufa wosanjikiza maphatikizidwe
Ufa wosanjikiza maphatikizidwe gawo mtanda gawo la ufa wosakanikirana ndi matenthedwe mphamvu.Kutentha kumasungunula zinthu zaufa ndikulimba zikazizira.Ndi ma polima, ufa wosagwiritsidwa ntchito mozungulira mbaliyo umagwiritsidwa ntchito kuti ugwire gawolo, kotero palibe chithandizo chowonjezera chomwe chimafunika nthawi zambiri.Pazigawo zachitsulo, anangula nthawi zambiri amafunika kugwirizanitsa zigawozo ku bedi losindikizira ndikuthandizira kutsika pansi.Laser sintering idagulitsidwa mu 1992, ndikutsatiridwa ndi sintering yothamanga kwambiri ndipo posachedwa, kuphatikiza ma jet angapo.Popanga zitsulo, zitsulo zolunjika za laser sintering ndi electron beam melting molding (EBM) ndi machitidwe otchuka kwambiri a mafakitale.
4. Kupopera mbewu mankhwalawa
Jakisoni wazinthu ndi imodzi mwa njira zofulumira kwambiri zopangira zowonjezera pogwiritsa ntchito mitu yosindikiza yamitundu yambiri.Zowonjezera kupanga madipoziti m'malovu a zinthu zomangamanga wosanjikiza ndi wosanjikiza.Dongosolo la jakisoni wazinthu zimatha kusindikiza zida zamitundu yambiri komanso zamagulu.Zigawo zimapangidwa mosiyanasiyana pamtundu uliwonse, zomwe zimapangitsa kuti pakhale mitundu yosiyanasiyana komanso zinthu zakuthupi.Kawirikawiri, machitidwewa amagwiritsa ntchito photopolymers, waxes ndi zipangizo zamakono zomwe ma photopolymers angapo amasakanikirana ndi kupopera panthawi imodzi.Njira monga ma jet amitundu yambiri ndi ma jetting amagwiritsidwa ntchito popanga ma prototyping mwachangu, zitsanzo zamaganizidwe, njira zoyendetsera ndalama, ndi mitundu yofananira yachipatala.
Takulandilani kuti mujambule!
