Aia nā tausani o nā palakiko ma ka mākeke no ka hana prototyping wikiwiki a i ʻole ka hana liʻiliʻi - ʻo ke koho ʻana i ka palakiko kūpono no kahi papahana kikoʻī hiki ke hoʻoluhi, ʻoiai no nā mea hana hou a i ʻole nā mea kālepa hou. Hōʻike kēlā me kēia mea i kahi ʻaelike ma ke ʻano o ke kumukūʻai, ka ikaika, ka maʻalahi a me ka hoʻopau ʻana o ka ʻili. Pono e noʻonoʻo ʻaʻole wale i ka hoʻopili ʻana o ka ʻāpana a i ʻole ka huahana, akā ʻo ke kaiapuni e hoʻohana ʻia ai.
Ma keʻano laulā, ua hoʻomaikaʻi nā palakiko ʻenekinia i nā waiwai mechanical e hāʻawi ana i ka lōʻihi o ke kūpaʻa a ʻaʻole e loli i ka wā o ke kaʻina hana. Hiki ke hoʻololi ʻia kekahi mau ʻano palakiko e hoʻomaikaʻi i ko lākou ikaika, a me ke kūpaʻa ʻana i ka hopena a me ka wela. E luʻu kākou i loko o nā mea palakiko like ʻole e noʻonoʻo ai ma muli o ka hana o ka ʻāpana hope a huahana paha.
ʻO kekahi o nā resins maʻamau i hoʻohana ʻia e hana i nā ʻāpana mīkini ʻo nylon, i ʻike ʻia hoʻi ʻo polyamide (PA). Ke hui ʻia ka polyamide me ka molybdenum, he ʻili laumania kona no ka neʻe maʻalahi. Eia nō naʻe, ʻaʻole ʻōlelo ʻia nā kia nylon-on-nylon no ka mea, e like me nā plastics, pili pinepine lākou. Loaʻa iā PA ke kūpaʻa kiʻekiʻe i ka ʻaʻahu a me ka abrasion, a me nā waiwai mechanical maikaʻi i nā mahana kiʻekiʻe. He mea kūpono ʻo Nylon no ka paʻi 3D me ka plastic, akā omo ia i ka wai i ka hala ʻana o ka manawa.
He koho maikaʻi loa nō hoʻi ʻo Polyoxymethylene (POM) no nā ʻāpana mīkini. ʻO POM kahi resin acetal i hoʻohana ʻia e hana i ka DuPont's Delrin, kahi plastic waiwai nui i hoʻohana ʻia i nā kia, nā wili, nā huila a me nā mea hou aku. Loaʻa iā POM ka ikaika flexural a me ka tensile kiʻekiʻe, ka paʻakikī a me ka paʻakikī. Eia nō naʻe, ua hoʻohaʻahaʻa ʻia ʻo POM e ka alkali, chlorine a me ka wai wela, a he paʻakikī ke hoʻopili pū.
Inā he ʻano ipu kāu papahana, ʻo ka polypropylene (PP) ke koho maikaʻi loa. Hoʻohana ʻia ka Polypropylene i loko o nā ipu mālama meaʻai no ka mea he kūpaʻa ia i ka wela, ʻaʻole hiki ke komo i nā aila a me nā mea hoʻoheheʻe, a ʻaʻole hoʻi e hoʻokuʻu i nā kemika, e palekana ai ka ʻai ʻana. Loaʻa iā Polypropylene kahi kaulike maikaʻi loa o ka paʻakikī a me ka ikaika o ka hopena, e maʻalahi ai ka hana ʻana i nā loops hiki ke kulou pinepine ʻia me ka ʻole o ka haki ʻana. Hiki ke hoʻohana ʻia i loko o nā paipu a me nā hoses.
ʻO kekahi koho ʻē aʻe ʻo ia ka polyethylene (PE). ʻO PE ka palakiko maʻamau ma ka honua me ka ikaika haʻahaʻa, ka paʻakikī a me ka ʻoʻoleʻa. He palakiko keʻokeʻo waiū ia i hoʻohana ʻia e hana i nā ʻōmole lāʻau lapaʻau, ka waiū a me nā ipu detergent. Kūpaʻa loa ka Polyethylene i nā ʻano kemika like ʻole akā he haʻahaʻa kona kiko heheʻe.
He kūpono ka mea Acrylonitrile butadiene styrene (ABS) no kekahi papahana e koi ana i ke kūpaʻa hopena kiʻekiʻe a me ke kūpaʻa haehae a me ka haki kiʻekiʻe. He māmā ka ABS a hiki ke hoʻoikaika ʻia me ka fiberglass. ʻOi aku ke kumukūʻai ma mua o ka styrene, akā ʻoi aku ka lōʻihi o ka lōʻihi ma muli o kona paʻakikī a me ka ikaika. Hoʻohālikelike 3D ABS Fusion-molded no ka prototyping wikiwiki.
Ma muli o kona mau waiwai, he koho maikaʻi ʻo ABS no nā mea hiki ke hoʻokomo ʻia. Ma Star Rapid, ua hana mākou i ka hihia smartwatch no E3design me ka hoʻohana ʻana i ka plastic ABS/PC i pena mua ʻia i ʻeleʻele i hoʻoheheʻe ʻia. ʻO kēia koho o nā mea e hoʻolilo i ka hāmeʻa holoʻokoʻa i mea māmā, me ka hāʻawi pū ʻana i kahi hihia e hiki ke kū i nā haʻalulu i kekahi manawa, e like me ka wā e paʻi ai ka uaki i kahi ʻili paʻakikī. He koho maikaʻi ka polystyrene hopena kiʻekiʻe (HIPS) inā makemake ʻoe i kahi mea versatile a pale i ka hopena. He kūpono kēia mea no ka hana ʻana i nā hihia mea hana mana paʻa a me nā hihia mea hana. ʻOiai he kūpono ke kumukūʻai o HIPS, ʻaʻole lākou i manaʻo ʻia he aloha i ke kaiapuni.
He nui nā papahana e kāhea ana no nā resins hoʻoheheʻe injection me ka elasticity e like me ka rubber. He koho maikaʻi ka polyurethane Thermoplastic (TPU) no ka mea he nui nā ʻano kūikawā no ka elasticity kiʻekiʻe, ka hana haʻahaʻa haʻahaʻa a me ke kūpaʻa. Hoʻohana ʻia ʻo TPU i nā mea hana mana, nā wili, ka insulation cable, a me nā mea haʻuki. Ma muli o kona kūpaʻa solvent, loaʻa iā TPU ka ikaika abrasion a me ka shear a hiki ke hoʻohana ʻia ma nā ʻano ʻoihana he nui. Eia nō naʻe, ua ʻike ʻia no ka omo ʻana i ka makū mai ka lewa, e paʻakikī ai ke hana i ka wā o ka hana ʻana. No ka hoʻoheheʻe injection, aia ka rubber thermoplastic (TPR), he mea kūʻai ʻole a maʻalahi hoʻi e lawelawe, e like me ka hana ʻana i nā paʻa rubber shock-absorbing.
Inā makemake kāu ʻāpana i nā aniani moakaka a i ʻole nā puka makani, ʻoi aku ka maikaʻi o ka acrylic (PMMA). Ma muli o kona paʻakikī a me ke kūpaʻa i ka abrasion, hoʻohana ʻia kēia mea e hana i nā puka makani hiki ʻole ke haki e like me ka plexiglass. Hoʻopili maikaʻi ʻia ka PMMA, loaʻa ka ikaika tensile maikaʻi, a he kūpono ke kumukūʻai no ka hana nui. Eia naʻe, ʻaʻole ia e like me ka hopena a i ʻole ke kūpaʻa kemika e like me ka polycarbonate (PC).
Inā makemake kāu papahana i kahi mea ikaika aʻe, ʻoi aku ka ikaika o ka PC ma mua o ka PMMA a he mau waiwai optical maikaʻi loa ia, e lilo ia i koho kūpono no nā aniani a me nā puka makani pale pōkā. Hiki ke pelu ʻia a hoʻokumu ʻia ka PC ma ka mahana o ka lumi me ka ʻole o ka haki ʻana. He mea pono kēia no ka prototyping no ka mea ʻaʻole ia e koi i nā mea hana mold pipiʻi e hana. ʻOi aku ke kumukūʻai o ka PC ma mua o ka acrylic, a ʻo ka hoʻolōʻihi ʻana i ka wai wela hiki ke hoʻokuʻu i nā kemika ʻino, no laila ʻaʻole ia e hoʻokō i nā kūlana palekana meaʻai. Ma muli o kona hopena a me ke kūʻē ʻana i ka ʻōpala, kūpono ʻo PC no nā ʻano hana like ʻole. Ma Star Rapid, hoʻohana mākou i kēia mea e hana i nā hale no nā kikowaena lima o Muller Commercial Solutions. Ua mīkini ʻia ka ʻāpana ma CNC mai kahi poloka paʻa o PC; ʻoiai pono e moakaka loa, ua one ʻia e ka lima a ua hoʻowali ʻia me ka mahu.
He ʻike pōkole wale nō kēia o kekahi o nā palakiko i hoʻohana nui ʻia i ka hana ʻana. Hiki ke hoʻololi ʻia ka hapa nui o kēia mau mea me nā olonā aniani like ʻole, nā mea hoʻopaʻa UV, nā lubricants a i ʻole nā resins ʻē aʻe e hoʻokō ai i kekahi mau kikoʻī.
ʻO Gordon Stiles ka mea nāna i hoʻokumu a me ka pelekikena o Star Rapid, kahi hui hana prototyping wikiwiki, mea hana wikiwiki a me ka hana haʻahaʻa. Ma muli o kāna ʻike ʻenekinia, ua hoʻokumu ʻo Stiles iā Star Rapid i ka makahiki 2005 a ma lalo o kāna alakaʻi ʻana ua ulu ka hui i 250 mau limahana. Hoʻolimalima ʻo Star Rapid i kahi hui honua o nā ʻenekinia a me nā loea e hoʻohui i nā ʻenehana holomua e like me ka paʻi 3D a me ka mīkini CNC multi-axis me nā ʻano hana kuʻuna a me nā kūlana kiʻekiʻe. Ma mua o kona komo ʻana iā Star Rapid, nona a hoʻokele ʻo Styles iā STYLES RPD, ka hui hana prototyping wikiwiki a me nā mea hana nui loa ma UK, i kūʻai ʻia aku iā ARRK Europe i ka makahiki 2000.
