Pehea ka pololei o nā ʻāpana paʻi 3D?

1. He aha ka pololei

I ka pōkole, ʻo ka pololei ke kokoke loa o nā ʻāpana i hana maoli ʻia e kūlike i ka nui a me ke ʻano o ka hoʻolālā kumu, kahi ana. Ma muli o ka hilinaʻi o nā mīkini paʻi 3D i nā ʻāpana neʻe he nui, ʻaʻole e hana kēia hana i kahi hapa 100% pololei (ʻaʻole hoʻi e hana i kahi hana). Hōʻike maʻamau ʻia ka pololei i nā anakahi o ka pākēneka a i ʻole nā ​​millimeter, e like me ka ± 1% a i ʻole ka 0.5 mm.

2. Ka pololei o nā ʻenehana paʻi 3D ʻokoʻa

ʻokoʻa 3D pai ʻokoʻa ka pololei o nā ʻenehana.

FDM

ʻO ka fosed deposition i kēia manawa ka ʻenehana paʻi 3D i makemake nui ʻia (no ka mea ʻo ia ka mea hiki ke kūʻai ʻia), a me ka nui o nā ʻoneki e hoʻohana nei i kēia ʻenehana.

ʻO ka pololei o kahi mīkini paʻi FDM 3D ma kahi o ± 0.5 mm. ʻO ka pololei o nā mīkini paʻi FDM ʻoihana ma kahi o ± 0.2 mm.

SLA, DLP

Hoʻohana nā ʻenehana paʻi kiʻi Photopolymerization e like me SLA a me DLP i nā kumuwaiwai māmā e like me nā laser a me nā papahana e hoʻōla i nā resins photosensitive. ʻO ka pololei e pili ana iā ± 0.1 mm. ʻO ka pololei o kahi paʻi 3D resin ʻoihana e pili ana iā ± 0.01 mm.

SLS

ʻO ka sinter laser Selective, kahi e hoʻohana ai i kahi laser e hana i nā pauka sinter, ka pauma maʻamau nylon. ʻO ka pololei e pili ana iā ± 0.3 mm.

SLM

ʻO nā kaʻina hana fusion metala e like me SLM e hoʻohana ai i nā lasers e hoʻoheheʻe a i ʻole sinter metala paukū ʻāpana me ka pololei o kahi ± 0.1 mm.

Mea lele mokulele

ʻOiai ʻaʻole maʻamau e like me nā ʻenehana like, pololei loa ka ejection mea no ka mea ʻaʻole pono ia i ka hoʻomehana, hiki ke hoʻololi i ka deformation, e like me ka warping. ʻO ka pololei e pili ana iā ± 0.05 mm.

3. ʻO nā kumu ʻē aʻe e pili ana i ka pololei dimensional

Ke ʻano 3D pai ʻAʻole kaʻenehana wale nō ka mea e hoʻoholo ai i ka pololei o ka paʻi 3D. Loaʻa ka hopena o nā meahana, hoʻolālā hapa a me nā palena paʻi i ka pololei.

ʻO ka maikaʻi o ka mea paʻi: Aia kahi ākea nui ma waena o ka maikaʻi o nā mea paʻi kiʻekiʻe a me nā mea paʻi komo. ʻO nā mea paʻi 3D pae ʻoneki wale nō i kūʻai ʻia he mau tausani, a hoʻomaka nā mea paʻi 3D pae kiʻekiʻe mai nā kaukani tausani. ʻO ka ʻokoʻa o nā ʻenehana uila e like me nā motika stepper i hoʻohana ʻia i nā kumukūʻai like ʻole hiki ke noʻonoʻo ʻia.

Hoʻolālā ʻāpana: ʻOiai ʻo nā mea paʻi 3D maikaʻi loa hiki ʻole ke paʻi pololei i nā ʻāpana 3D i hoʻolālā maikaʻi ʻia. ʻO kahi laʻana, nui loa ka wahi, lōʻihi ka lōʻihi, a ʻaʻohe kākoʻo.

Nā Pono Hana: ʻOi aku ka maʻalahi o kekahi mau mea e paʻi ma mua o nā mea ʻē aʻe, no laila ua maʻalahi lākou i ka hana ʻana i nā ʻāpana kikoʻī. ʻO nā kumuwaiwai ʻole kaulike (e like me PLA hikiwawe, hoʻopili nā alloys i piha i nā metala makamae) e mōhai pinepine i ka paʻi hiki ke hoʻololi ʻia no kā lākou pono kū hoʻokahi.

ʻO nā palena paʻi: Hiki i ka mea hoʻohana ke hoʻopilikino i nā palena paʻi e like me ka pae hoʻonohonoho o ka mīkini paʻi, e like me ke kiʻekiʻe o ka papa, ka wikiwiki o ka paʻi ʻana, hoʻopihapiha ʻana i nā mea, a me nā mea ʻē aʻe. ʻO kahi laʻana, ʻo ka wikiwiki o ka wikiwiki paʻi, ʻo ka haʻahaʻa o ka pololei.

ʻEhā, pehea e hoʻomaikaʻi ai i ka paʻi paʻi 3D

Holoi a maʻalahi i nā hiʻohiʻona paʻakikī i ka hoʻolālā ʻana i nā ʻāpana.

E hoʻokuʻu aku i ka faile STL ma kahi hoʻonā kiʻekiʻe loa.

Hoʻohui mau i ka mīkini paʻi 3D a i ʻole ma mua o nā hana paʻi nui.

E hoʻohana i nā kākoʻo e hoʻokūpaʻa i nā mea ke paʻi, a akahele i ka hemo ʻana i nā kākoʻo e hōʻalo i nā ʻāpana hōʻino a i ʻole ka hoʻololi ʻana i kā lākou nui loa.

E hoʻohana i kahi moena pai wela (FDM) a i ʻole keena wela (SLS / metala) e mālama i ka mahana o nā ʻāpana e hōʻemi i ka deformation.

Inā ʻaʻohe koi manawa, e hoʻēmi i ka wikiwiki o ka paʻi ʻana e like me ka hiki.
