Hoʻopili ʻia ka paʻi 3D i nā ʻano hana prototyping. ʻO ka prototyping wikiwiki kekahi o nā ʻenehana nui i hoʻohana ʻia i ka paʻi 3D. He ʻano hana prototyping pili kālā maikaʻi. He mea paahana ka Rapid prototyping i nā hoʻololi kumu kūʻai ma muli o nā pilikia i ʻike ʻole ʻia i ka wā o ka hana piha piha, SLA Rapid Prototyping Vs SLS Rapid Prototyping.
Ua kaulana ka Steeolithography a me ka sintering laser koho. Hoʻohana lākou i nā lasers akā ʻokoʻa kā lākou kaʻina noi. Pehea ka pili ʻana o nā mea ʻelua a pehea e hana ai?
Hoʻohana ka Steeolithography i kahi mīkini kūikawā i kapa ʻia ʻo ka stereolithography apparatus e hoʻololi i ka polymer molten i kahi huahana 3D paʻa. Ke hele mai nei me nā hale me nā geometries paʻakikī, nā hiʻohiʻona manaʻo, nā ʻano kumu mua i ka hoʻolei ʻana i ka urethane a me nā hiʻohiʻona hoʻokahi, pono loa nā mīkini stereolithography. ʻO ka stereolithography apparatus he laser ultraviolet, he paepae puka, wai plastik a me kahi polokalamu kamepiula e hoʻomalu ana i ka paepae. Hoʻopili ʻia kahi papa photopolymer i ka paepae puka e ʻimi i ka ʻāpana keʻa o nā ʻāpana i paʻi ʻia. Hiki ke ho'ōla a paʻakikī ka palaki wai i ka wā e ʻike ʻia ai i ka UV, hana ʻia kahi papa hou. A hoʻohaʻahaʻa ʻia ke kahua a hōʻike ʻia kahi papa hou o ka plastik wai i ka wā e paʻakikī ai.
Ke hoʻohana nei ʻo SLS i kahi ʻāpana lahilahi o nā ʻāpana liʻiliʻi e like me ka ceramic, plastic a i ʻole aniani i hoʻohui ʻia e ka laser mana kiʻekiʻe e hana i kahi ʻāpana paʻa. Paʻi nā mīkini SLS i nā hiʻohiʻona 3D o nā mea e like me ka ceramics, plastics a me nā metala. Hoʻomaka ka SLS me kahi hoʻolālā ʻano CAD. Hoʻopuehu ʻia nā mea ma luna o ka paepae i kūkulu ʻia i loko o ka mīkini SLS. ʻO ka laser infrared a laila hoʻohui ka laser i nā ʻāpana e hana i ka papa ma ka papa geometries.
I ka wā e koho ai iā SLA a me SLS, pono ʻoe e noʻonoʻo i kekahi mau mea e like me ka hoʻonā ʻana, ke ʻano, ka hiki ke kū i ka abrasion a me ka hiki ke kūpaʻa mechanical.
Hoʻoholo nā mīkini SLA i nā huahana ʻoi aku ka maikaʻi ma mua o SLS ma ka ʻaoʻao a me ka pae. Loaʻa i ka ʻāpana SLS nā ʻōhū ea microscopic ʻaʻole hiki ke ʻike ʻia e ka maka ʻokoʻa akā hoʻopā ʻia, ʻaʻaʻa ka ʻili. SLS nā papahana e hana ma lalo o nā kūlana o ka mahana, ka haʻahaʻa a me nā kemika. Loaʻa i ka mea SLA ka mea hiki ke pale i ka abrasion i hoʻohālikelike ʻia me ka mea SLS.
Loaʻa i kēlā me kēia ʻenehana paʻi kona mau pono a me nā hemahema. Inā makemake ʻoe i ka hana, ʻo SLS prototyping ke ala e hele ai. Inā makemake ʻoe i nā palena mechanical, ʻo SLA ke koho kūpono.
E kākoʻo iā mākou ma [pale ʻia ka leka uila] i kēia lā e aʻo hou aku e pili ana SLA Rapid Prototyping Vs SLS Rapid Prototyping!
