3D Pai

ʻO ka lawelawe paʻi 3D wikiwiki prototyping ʻoihana, inā he pololei paʻi SLA 3D a i ʻole paʻi paʻi SLS 3D paʻa, hiki iā ʻoe ke hoʻomaopopo pono i kāu hoʻolālā me ka ʻole o nā kapu.

Nā pono o ka paʻi 3D

  • E hoʻopōkole i nā manawa lawe - hiki ke hoʻouna ʻia i nā ʻāpana i loko o kekahi mau lā, e wikiwiki ana i nā ʻōkuhi hoʻolālā a me ka manawa e kūʻai aku ai.
  • Kūkulu i ka Geometry Complex - ʻĀpono i ka hana ʻana i nā ʻāpana kūikawā me nā geometry ʻoi aku ka paʻakikī a me nā kikoʻī kikoʻī me ka ʻole e hoʻonui i nā kumukūʻai.
  • Hoʻoemi i nā kumukūʻai hana - Hoʻokele e hōʻemi i nā kumukūʻai hana i ka hoʻopau ʻana i ka pono no nā pono hana a hoʻemi i ka hana.

He aha ka 3D Prototype paʻi?

ʻO ka paʻi 3D kahi manawa ākea e hoʻohana ai e wehewehe i ka hana additive, kahi e hoʻopili ana i nā ʻenehana prototyping wikiwiki e hoʻohui i nā papa o nā mea e hana i nā ʻāpana.

ʻO ka paʻi wikiwiki 3D prototyping 3D ka ala wikiwiki, maʻalahi a me ke kumu kūʻai kūpono e hoʻolilo i nā manaʻo maikaʻi i nā huahana kūleʻa. ʻAʻole kōkua kēia mau prototypes paʻi 3D e hōʻoia i ka hoʻolālā akā ʻike pū i nā pilikia i ka hoʻomaka ʻana o ka hana hoʻomohala a me ka pane pololei i ka hoʻoponopono hoʻolālā, pale ʻana i nā loli nui ke hana ʻia ka huahana.

No ke aha e koho ai i ka Createproto No ka lawelawe paʻi 3D?

He loea ʻo Createproto i ke kahua o ka hana wikiwiki prototyping ma Kina, e hāʻawi ana i ka laulā o nā lawelawe paʻi 3D, e like me ka paʻi ʻana o SLA 3D (Stereolithography), ka paʻi SLS 3D (Selective Laser Sintering).

Ma Createproto Loaʻa iā mākou kahi hui piha o nā ʻenekini hoʻolaʻa a me nā luna o ka papahana e hana pū me ʻoe e hōʻoia i kāu hoʻolālā CAD, nā hana huahana, nā hoʻomanawanui dimensional, a me nā mea hana pilikino prototype, ʻike hohonu mākou i ka prototype a me nā pono hana o kekahi ʻoihana. Hoʻoikaika mākou e hālāwai i nā manawa kikoʻī āpau e hāʻawi i nā huahana me nā hōʻoia maikaʻi i kā mākou mea kūʻai aku ma ka honua holoʻokoʻa ma nā kumukūʻai kumukūʻai.

He aha ka paʻi SLA 3D?

Hoʻohana ka SLA 3D Pai (Stereolithography) i kahi kukuna ultraviolet e huki ana ma luna o ka resin thermoset wai e hana ai i mau kaukani lahilahi a hiki i ka hoʻokumu ʻia ʻana o nā ʻāpana hope loa. ʻO kahi koho ākea o nā mea, nā hoʻonā hiʻohiʻona kiʻekiʻe loa, a me nā hoʻopau pae maikaʻi e hiki me ka SLA 3D Pai.

Pehea e hana ai ka SLA 3D Pai?

  • Ka hana ʻikepili, lawe ʻia ka Model 3D i kahi papahana slicing o nā polokalamu ponoʻī, me nā kākoʻo kākoʻo i hoʻohui ʻia e pono ai.
  • Hoʻouna ʻia ka faile STL e paʻi ma ka mīkini SLA, me kahi pahu i hoʻopiha ʻia me ka resin photosensitive wai.
  • Hoʻohaʻahaʻa ʻia kahi paepae hale i loko o ka pahu. ʻO ka kukuna kukuna UV e kia ana ma o ka aniani scour contour o ke keʻa mahele o ka wai.
  • Hoʻopaʻa koke ka kēpau i ka ʻimi scanning e hana i hoʻokahi papa o nā mea. Ke hoʻopau ʻia ka papa mua ua hoʻohaʻahaʻa ʻia ka paepae e 0.05-0.15mm me kahi papa hou o ka kēpau e uhi ana i ka ʻili kūkulu.
  • Kuhi ʻia ka papa aʻe, e hoʻōla ana a hoʻopaʻa i ka kēpau i ka papa o lalo. A laila hana hou i kēia hana a kūkulu ʻia ka ʻāpana.

He aha ka paʻi SLS 3D? 

Hoʻohana ka SLS 3D Pai (Stereo Laser Sintering) i kahi kukuna optic mana kiʻekiʻe e hoʻopili i nā huna ʻāpana liʻiliʻi e ka papa e hana i nā ʻāpana geometric paʻakikī a paʻa. Kūkulu ka paʻi SLS 3D i nā ʻāpana ikaika me nā mea hana Nylon piha, kūpono no nā prototypes hana a me nā ʻāpana hoʻohana hope.

Pehea e hana ai ka paʻi paʻi SLS 3D?

  • Hoʻolahalaha ka pauka i kahi papa lahilahi ma luna o kahi paepae i loko o ka lumi i hoʻokino ʻia.
  • Ke hoʻomehana ʻia ma lalo pono o ka mahana hoʻoheheʻe o ka polymer, nānā kahi kukuna kukuna i ka pauka e like me ke kaʻe o ka papa o ka papa a me nā synters i ka mana. Kākoʻo ka pauka unsintered i ka lua a me ka cantilever o ke k .kohu.
  • Ke hoʻopau ʻia ka sinter o ka ʻāpana keʻa, e emi ka mānoanoa o ka paepae e hoʻokahi papa, a hohola ka lole wili hoʻomoe i kahi papa o ka pauka kaulike ma luna ona no ka ʻoki ʻana i kahi ʻāpana keʻa hou.
  • Hoʻomaʻa hou ʻia ke kaʻina a hiki i ka hoʻololi ʻia ʻana o nā papa āpau e loaʻa ai ke kumu paʻa.

Hoʻohālikelike i nā hiki aʻe o SLA a me SLS e koho i ka lawelawe paʻi paʻi 3D kūpono

Nā Pono Pono

Loaʻa ka paʻi SLS 3D i nā mea a hiki ke hana ʻia i ka palakiko, metala, pālolo, a i ʻole nā ​​kīʻaha aniani me ka hana maikaʻi. Hiki i nā mīkini Createproto ke hana i nā ʻāpana i ke keʻokeʻo Nylon-12 PA650, PA 625-MF (Mineral Filled) a i ʻole PA615-GF (Glass Piha). Eia nō naʻe, hiki i ka paʻi SLA 3D ke lilo i polymer photosensitive wai wale nō, a maikaʻi ʻole kāna hana e like me ka plastic thermoplastic.

Pau ka ʻili

ʻO ka papa o ka prototype e ka paʻi ʻana o SLS 3D he ākea a paʻakikī hoʻi, ʻoiai ʻo ka paʻi ʻana o SLA 3D e hāʻawi nei i ka wehewehe kiʻekiʻe e hoʻomaʻemaʻe i ka ʻāpana o nā ʻāpana a me nā kikoʻī.

Kūpono Dimensional

No ka paʻi SLA 3D, Mīkini Pākuʻikuʻu liʻiliʻi = 0.02 ”(0.5mm); Tolerances = ± 0.006 "(0.15mm) a i ka 0.002" (0.05mm).
No ka paʻi SLS 3D, Mīkini Pākuʻikuʻu liʻiliʻi = 0.04 "(1.0mm); Tolerances = ± 0.008 "(0.20mm) i ka ± 0,004" (0.10mm).
Hiki i ka paʻi 3D SLA ke kūkulu i nā hoʻonā kiʻekiʻe me kahi anawaena kukuna finer maikaʻi a me nā ʻāpana o ka ʻāpana finer e hoʻomaikaʻi ai i nā kikoʻī a me ka pololei.

Ka Hana Hana Mīkini

Hoʻohana ka paʻi SLS 3D i nā mea thermoplastic maoli e hana i nā ʻāpana me nā pono mechanical maikaʻi. Hoʻomaʻamaʻa maʻalahi ʻia ka SLS, a hiki ke maʻalahi i ka wili, ʻeli ʻana, a me ke kāomi ʻana ʻoiai e lawelawe ʻia ka mīkini SLA 3D me ka mālama inā pilikia ka ʻāpana.

Ke kūʻē ʻana i ke kaiapuni

ʻO ke kūʻē ʻana o nā prototypes paʻi SLS 3d i ke kaiapuni (ka mahana, ka mahana, a me ka hoʻowahā ʻana o nā kemika) like ia me nā mea thermoplastic; Hiki i nā prototypes paʻi SLA 3d ke maʻalahi i ka pulu a me ka hoʻoneoneo ʻino, a ma nā wahi ʻoi aku ma mua o 38 soft e lilo lākou i palupalu a hemahema hoʻi.

Ka ikaika hoʻopili paʻa

ʻOi aku ka ʻoi o ka ikaika paʻa paʻi SLS 3D ma mua o ka paʻi SLA 3D, no ka mea he nui nā pores ma ka ʻili o ka hoʻopaʻa ʻana o SLS e hāʻawi i ka infiltration o viscose.

Laʻana o ke Kumu

Kūpono ka paʻi SLA 3D no ka hana kope ʻana o ka kumu kumu prototype, no ka mea he wahi laumania ia, kūpaʻa dimensional maikaʻi a me nā hiʻohiʻona maikaʻi.

Hoʻohālikelike i nā hiki aʻe o SLA a me SLS e koho i ka lawelawe paʻi paʻi 3D kūpono

Hana hana hoʻoiho & hoʻohui

Hoʻomaopopo pū ʻia ka paʻi 3D me ka hana ʻana i mea hoʻohui, kahi kūkulu i nā ʻāpana ma o nā papa o nā mea. He nui kona mau maikaʻi ma mua o nā kaʻina hana kuʻuna akā he pilikia kona. ʻO ka mīkini ʻana ʻo CNC kahi hana subtractive maʻamau i hoʻohana ʻia no nā ʻāpana hana, kahi e hana i nā ʻāpana ma ke ʻoki ʻana i ka hakahaka.

Nā Pono Pono & Loaʻa

ʻO ke kaʻina paʻi 3D e pili ana i nā ʻāpana i hana ʻia e ka papa e hoʻohana ana i nā mea e like me nā resins photopolymer wai (SLA), nā kulu o ka photopolymer (PolyJet), nā palaka a me nā pauka hao (SLS / DMLS), a me nā filament ea (FDM). No laila hana ia i nā ʻōpala liʻiliʻi i hoʻohālikelike ʻia me ka hana CNC. E ʻoki ana ka mīkini ʻana ʻo CNC mai kahi ʻāpana o nā mea āpau, no laila haʻahaʻa ka hoʻohana ʻana o nā mea. ʻO ka pōmaikaʻi aneane hiki i nā mea āpau ke mīkini ʻia me CNC, e like me nā plastics ʻenehana hana a me nā mea hao like ʻole. ʻO kēia ke ʻano o ka mīkini ʻana ʻo CNC ka ʻenehana kūpono no nā prototypes a me ka hoʻohana ʻana i nā ʻāpana i hana nui ʻia e pono ai nā hana kiʻekiʻe a me nā hana kūikawā.

Ka pololei, ʻilikai a me ka paʻakikī Geometric

Hiki i ka paʻi 3D ke hana i nā ʻāpana me nā geometry paʻakikī a hiki i ke ʻano hollow ʻaʻole hiki ke hana ʻia e ka mīkini ʻana o CNC, e like me nā mea nani, nā hana lima, a pēlā aku. Hāʻawi ka mīkini ʻana ʻo CNC i ka ʻoi aku ka nui o ka dimensional (± 0.005mm) a me nā hoʻopau maikaʻi ʻoi loa (Ra 0.1μm) Hiki i nā mīkini wili 5-axis ʻoihana kiʻekiʻe ke hana i ka mīkini kiʻekiʻe kiʻekiʻe o nā ʻāpana paʻakikī e kōkua iā ʻoe e kū i kāu mau pilikia hana paʻakikī.

ʻO ke kumukūʻai, ka nui a me ka manawa hāʻawi

Hana ka 3D paʻi i nā mea haʻahaʻa i nā hapa me ka ʻole o kahi mea hana, a me ka ʻole o ke kōkua kanaka, i hiki ai ke huli wikiwiki a me ke kumukūʻai haʻahaʻa. Hoʻolako ʻia ke kumukūʻai hana o ka paʻi 3D ma muli o ka nui o nā mea, ʻo ia hoʻi nā ʻāpana nui a ʻoi aku paha ke kumu kūʻai. Kūpilikiʻi ke kaʻina hana o ka mīkini ʻana o CNC, koi ʻia i nā ʻenekini hoʻomaʻamaʻa kūikawā e polokalamu mua i nā palena hana a me ke kaʻina hana o nā ʻāpana, a laila mīkini e like me nā papahana. No laila ua ʻōlelo ʻia nā kumukūʻai hana me ka noʻonoʻo ʻana i ka hana hou. Eia nō naʻe, hiki i nā mīkini CNC ke holo mau me ka ʻole o ka nānā ʻana o ke kanaka, e kūpono ana no nā puke nui aʻe.
