No ke aha ʻoe e pono ai i ka mīkini paʻi 3D ʻoihana SLA.

Me nā mea paʻi paʻi 3D pākaukau kūpono, nā mea paʻi 3D kūpaʻa wela, a me nā mīkini hoʻoheheʻe injection, hiki ke hana i nā mold injection paʻi 3D i loko o ka hale e hana i nā prototypes hana a me nā ʻāpana hana liʻiliʻi i loko o nā plastics hana. No ka hana haʻahaʻa haʻahaʻa (ma kahi o 10-1000 mau ʻāpana), 3D paʻi paʻi ʻia ʻana e mālama i ka manawa a me ke kālā ke hoʻohālikelike ʻia me nā ʻāpana metala makamae. Hāʻawi lākou i kahi ala hana ʻoi aku ka agile, e ʻae i nā mea ʻenekinia a me nā mea hoʻolālā e prototype i nā mold injection a hoʻāʻo i ka hoʻonohonoho ʻana a i ʻole e hoʻololi maʻalahi i nā mold a hoʻomau i ka hoʻololi ʻana i kā lākou mau hoʻolālā me nā manawa alakaʻi haʻahaʻa a me nā kumukūʻai.

ʻO ka ʻenehana paʻi SLA 3D kahi koho maikaʻi loa no ka hana ʻana. Hōʻike ʻia ia e ka hoʻopau ʻana i ka ʻili maʻemaʻe a me ka pololei kiʻekiʻe e hoʻoneʻe ʻia ka ʻōpala i ka ʻāpana hope a e hoʻomaʻamaʻa hoʻi i ka demolding. ʻO nā paʻi 3D i hana ʻia e SLA ua hoʻopaʻa paʻa ʻia lākou e like me ka paʻa piha a me ka isotropic, e hana ana i nā mole hana i kahi ʻano hiki ʻole me ka fused deposition modeling (FDM). ʻO nā mea paʻi paʻi resin SLA desktop a me ka papa kuhikuhi, e like me nā mea i hāʻawi ʻia e Formlabs, e hoʻomaʻamaʻa i ke kahe hana no ka mea maʻalahi lākou e hoʻokō, hana, a mālama.

ʻO ka Formlabs Rigid 10K Resin kahi mea ʻenehana, piha piha i ka aniani e lawelawe ana ma ke ʻano he mea hoʻoheheʻe kūpono no nā ʻano geometries a me nā kūlana kaʻina hana injection. Loaʻa iā Rigid 10K Resin kahi HDT o 218 ° C @ 0.45 MPa a me kahi modulus tensile o 10,000 MPa, e lilo ia i mea ikaika, ʻoʻoleʻa loa, a me ka thermally stable molding material e mālama i kona ʻano ma lalo o ke kaomi a me ka mahana e hana i nā ʻāpana pololei.

ʻO ka Rigid 10K Resin kahi mea e paʻi ai i nā mea hoʻoheheʻe maʻalahi no ka hoʻoheheʻe ʻana, a mākou e hōʻike nei me ʻekolu mau hihia i kā mākou pepa keʻokeʻo. Ua holo ʻo Farani ʻenehana ʻenehana IPC i kahi noiʻi noiʻi a paʻi i nā tausani o nā ʻāpana, hoʻohana ʻia ka mea hana ʻaelike Multiplus no ka hana haʻahaʻa haʻahaʻa, a ua hoʻokomo ʻo ka hui hoʻomohala huahana ʻo Novus Applications i nā haneli o nā pāpale intricately threaded me hoʻokahi Rigid 10K Resin mold.

ʻO ka High Temp Resin kahi mea ʻē aʻe i hiki ke noʻonoʻo ʻia i ka wā ʻaʻole kiʻekiʻe ke kiʻekiʻe o ka hoʻopaʻa ʻana a me ke kaomi ʻana a ʻaʻole hiki ke hoʻokō ʻo Rigid 10K Resin i nā mahana injection i koi ʻia. Loaʻa i ka High Temp Resin kahi wela wela (HDT) o 238 ° C @ 0.45 MPa, ka mea kiʻekiʻe loa ma waena o nā resins Formlabs a me kekahi o nā mea kiʻekiʻe loa ma waena o nā resins ma ka mākeke, e ʻae iā ia e kū i nā mahana hoʻoheheʻe kiʻekiʻe a hoʻemi i ka manawa hoʻomaha. ʻO kā mākou pepa keʻokeʻo e hele i kahi noiʻi hihia me Braskem, kahi hui petrochemical i holo i 1,500 mau pōʻai injection me hoʻokahi mea hoʻokomo i paʻi ʻia me High Temp Resin e hana i nā kaula mask. Ua paʻi ka hui i ka mea hoʻokomo a waiho ʻia i loko o kahi mold metallic generic i hoʻohui ʻia i loko o ka ʻōnaehana injection. He hopena ikaika kēia e hoʻopuka koke i ka moʻo waena.

ʻO ka High Temp Resin, akā, he palupalu. I ke ʻano o nā ʻano ʻano paʻakikī, ua maʻalahi a nahā paha. No kekahi mau hi'ohi'ona, hiki ke pa'akikī ka hiki 'ana aku ma mua o ho'okahi kakini. No ka hoʻoponopono ʻana i kēia pilikia, He haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ma mua o High Temp Resin, kahi e alakaʻi ai i kahi manawa hoʻomaha lōʻihi, akā ʻoi aku ka palupalu a hiki ke kū i nā haneli haneli.
