Mātai Molding ki te Tā 3D: Ko tēhea e pai ake ana mō tō hua?

Me Pēhea Te Mahi A Mātai Whakauru Me Te Wā Ka Pai Ai

He aha te mātai whakauru me pēhea te mahi?

Ko te hanga whakapūmau i ngā matēriau melmed, heoi anō ko ngā thermoplastics engari he wā pea ko ngā metara hoki, ki ngā mātai e hangaia ana mō ngā mātai e hiahiatia ana ai te pēhi tino teitei. E ai ki taua pūrongo i te tau 2024 mō ngā tikanga hangahanga, e waru ngā waehanga matua e pa ana. Tuatahi ko te paruru i te matēriau tuuturu kia rite ai te mahi. Ka whai mai te wā tono i reira ka taea te pēhi e 10 miriona ki te 20 miriona pauna per square inch. Muri atu ko te wā e hiahiatia ana kia maroke tonu, e pau ana i te 5 hēkona ki te haurua miniti e hiahiatia ana e te momo polymer e mahi ana i te wā. Whakamutunga, kia paku ake te wāhi, ka popokohia aunoa e ngā mīhini i te mātai. Ko te mea ataahua ki tēnei tikanga ko te pono o ana hua. Ētahi wāhanga ka puta mai me ngā dimensions tino pono anake ka rerekē anake mā te +5.000 ki te -5.000 inches. Ko te rite tonu o te taumata e hāngai ana ki te hanga i ngā wāhanga motuka e hiahiatia ana kia tāwhai tika, i ngā puna iti nei e whakamahia ana i ngā syringes hauora i reira ka nui te take o ngā rerekē iti.

Whakaputa kaha me te kounga tataungia me te hāritea

Ina ko te wānanga i ngā wāhanga pakuhi maha, ka tino ataahua te momonga inu. Ka taea e ngā mīhini whakangao hoko te whakaputa i te tekau mano o ngā wāhanga i ia haora, ka iti ake i te tekau hereni te utu mō ia wāhanga ina whakaputangia ngā rōrahi nui ake i te 10k. I kite tētahi ripene hou mai i te Rōpū Tūmatanui Mātai Pakuhi i tētahi mea hou - ka iti ake te momonga inu ki te 93% teitei i te momonga 3D ina ko ngā mahi whakaputa nui. He aha hoki te mea pai ake? Ko te tino ū ki ia wāhi whakaputa, ā, ko ngā ine e ū ana ki te 99.8% teitei o te pono i waenganui i ngā rōrahi. Ko te take o tēnei tūponotanga? Ko ngā taputapu hōu kei te matotoru i ngā punaha whakahaere mātau e rerekē tonu ana i ngā wāhi pērā i te wera (±1° C) me te toki (±50 psi) i te wā e hangaia ana ngā wāhanga. Ka pakari ēnei rerekē iti engari he mea nui i te wā e whakahaeretia ana, nō reira ko ia wāhanga e wehe mai ana i te rārangi e rite ana ki te wāhanga whakamutunga.

Te kaha o te matērihi, te roa o te ora, me te mata o ngā wāhanga āwhata kua hangaia

He nui ake te kaha mekameka o ngā wāhanga āwhata mōhio ki ētahi atu tikanga whakawhanaketanga. Ka taea e ngā pāremata pūtaiao pērā i te PEEK, ABS, me te polycarbonate te eke ki te kaha taraiwa o te 15,000 psi, e 40 miriona tōrahi ake rānei i ngā wāhanga 3D e hangaia ana. Ko te mea e tīmata ai te āwhata mōhiotia ko te huringa e mahi ana i te pēhi tino teitei hei tango i ngā raina ata kōrerorero e kitea ana. E hāngai ai ki ngā mata hāngai ka eke ki te taumata mata o raro i te Ra 0.8 microns, pērā noa i te mata paraire, kāore he hiahia ki ngā tapa whakapaipai. Ina tirohia ngā takotoranga toihenga herekau, ko ngā matērihi fluoropolymer e hangaia ana mā te āwhata mōhiotia e whakaatu ana i te roa o te ora. Kei te mau tonu rātou ina noho ana ki roto i te hinu mō te neke ake i te 500 haora e ai ki ngā tīmaurutanga ASTM, e whakaatu nei i te kaha ki te tautoko i ngā kimikime tūroa kaua mōhiotia.

Ngā utu taputapu, ngā wā tīmata, me ngā whakaaro mō te whakaurunga tuatahi

Ko te utu mo te hanga i ngā momi hiriwiri e noho ana te nuinga o te wā i waenganui i te waru mano ki te rau mano miriona dolarara, ā, ka take pea i te waru ki te tekau mā whā wiki te wā ki te hanga. Engari nā ēnei āhuatanga, ko te huarahi anake e whai ana ngā kamupene nui heke iho i te toru tau te roa o te ora o te hua. E ai ki te pūrongo a Machinery Today i te 2024, e kimsihia ana e te toru ki te whā o ngā kaihanga tēnei hei mea matua herekore mō ō rātou mahi. I te taha aronga atu, he tikanga ake ngā momi karaiti mō ngā kōpae whakaputa waenga, arā pea i waenganui i te rima mano ki te rau mano kotahi rau ngā kōpae. Ka penapena i te 35% te utu taputapu i te upoko o te hiriwiri, ā, ka wehe pea i te wā whakaputa ki te haurua. E kitea ana e maha ngā toihana tēnei āhuatanga hei tika ina whai kiko ana i ngā tahumaeroi engari anō hoki ki te tutuki i ngā here whakaputa.

Te utu ia kōpae i te paerewa: penapena i te wā roa ahakoa nui te utu tuatahi

Mō ngā kōwae e pā ana ki te 100,000, kaite hūnuku iho te utu mō ia wāhanga mā te 80—92% te whakamahi i te hanga pāpātanga inihua tāpiri i te 3D. Ko te wehenga utu e whakaatu nei:

• $120,000 te utu tuatahi mō te taputapu
• $0.09 te utu mātai mō ia wāhanga
• 12 sekene te wā mō ia maha

Ko te mutunga ko te utu o $1.23 ia wāhanga mō ngā 500,000 wāhanga—72% iti ake i te SLS nylon printing. Ko te pito o te ōrite kei waenganui i te 1,000 me te 5,000 wāhanga, e hāngai ana ki te herenga o te hoahoa me ngā here huringa.

ngā Pakanga o te Tākirikiri 3D: Te Tere, Te Maruaroa, me te Huarahi Iti

Te noho tūāpapa me te tautoko i ngā āhua herenga kīrehe kaua he taputapu

Ko te āhua o te takotoranga i te toru dimensions e hoatu ana i te noho whaiā i ngā kaihanga nā te mea ka hangaia ngā taonga ki ia paparanga mai i ngā kōnae rorohiko, nō reira ehara i te mea me wātea moni mō ngā tohu matū haukaha. Kei te tāpaingia te tāpahi tāwhaihono i ngā here herenga pērā i te hiahia ki ngā mata āwangawanga me ngā pāpaku e ōrite ana te tino katoa. Engari mā te hanga tāpiritanga, ka taea e ngā kaihanga te waihanga i ngā wāhi poka, ngā āhua tuku iho a-takotoranga, me ngā ara tuku roto herengia e kore e taea anō. E ai ki te rangahau i tāparihia e Wevolver i te tau ki muri, i te wa i huri ai ngā kamupene ki ngā arataki takotoranga 3D, i heke te whakamahinga o ngā whakaritenga ki te tekau mā whā miriona tōaitanga ina mātai ana ki ngā tikanga tawhito. Ko te mahi uaua pēnei e whakaatu ana i te rerekētanga i ngā wātaka whanaketanga hua.

Te whanaketanga tere arataki me te whanaketanga hoki hei tere ake i te wā ki te maakete

Kua āwhina tēnei hangarau i te huritau o te whanaketanga hua, ka poto ake ngā wātata mo ngā tauira tuatahi mai i ngā wiki ki ngā haora anake. Ka taea e ngā mātai hinu inaianei te hanga me te whakahaere tāpiri tāpiri arataki mō ētahi tauira hoahoa rerekē katoa i roto i tētahi rangi mahi anake—kāore tēnei i taea i mua me ngā tikanga mātātoko mōhini arataki, nā te mea i ia panonitanga iti ka hiahiatia he mātātoko hou. Kua kōrero ngā kamupene motukā mō ā rātou kapa poto i ngā tahumaero tuatahi ki te toru haurua i muri i te whakauru i te printa 3D ki te rerekētanga o te hoahoa.

Whanaketanga iti ki te waenga kīanga kāore he uara mōhini

Mō ngā huinga whakaputa i raro i te 10,000 wae, ka pakari te tuhi 3D i te whakaurunga tīmatanga $10,000—$100,000 e hiahiatia ana mō ngā pāpāri injita. Ka mahi tika tēnei mō te whakamātau i te tauhokohoko, ngā putanga iti, me te hanga ārai. Hei tauira, ka whakamahi ngā toihenga hauora i te tuhi 3D hei whakaputa i ngā arataki mātai mō ia pirihimana ki te utu iti ake 30% ake, i te tuanui i te mahi o te matū rongoā.

Ko te wā poka haere tere ake, me te whakapēpiha i ngā wā roa mō ngā tono noho rāwekenga, ritenga

Ko te hanga taunaki e hoatu ana ngā wae atamira i roto i ngā 24—72 haora, ka pakaru i ngā wā roa 8—12 wiki e hāngai ana ki te hanga pāpāri. Ko tēnei urupare e āwhina ana i te whakaputanga just-in-time, me te kawe tere i ngā tono ritenga. I te wātea tahi kaihautū rererangi i te wā kawe wae takotoranga mai i ngā 14 wiki ki ngā 3 rā mā te whakamahi i ngā whatunga tuhi 3D kua paparangitia.

Ngā Matatoko Tukanga: Te Whakawhitinga o ngā Tikanga Hangarua Taunaki me Tangohia

ko te tauira 3D e hanga ana i ngā taonga kotahi anō te papa iti ake, ka whakamahia ngā rauemi pērā i te paraihe, tēnei e āwhina ai ki te waihanga i ngā āhua e kore e taea e ngā tikanga whakaputa noa. Hei tauira ko te whakauru paraihe, kei reira ka pūhia te paraihe rerehua ki roto i ngā tohu hiko, mātātoko rānei ki te pēhi tino teitei hei hanga i te nui o ngā wāhanga tōpapa. Ko te rerekētanga nui ko ngā kārika 3D e taea ai ngā hanganga takirua hihiri me ngā puranga māori, ā, ko te whakauru paraihe e hiahiatia ana ngā karu tāpoi e kore e taea te panonitanga, engari e hoatu ana i ngā hua tōpapa ia wā. Ko te hanga i ēnei karu he nuinga o te CNC machining, ka tapahia ngā rauemi engari kāore i te tāpiri, ā, ka riro tēnei tukanga katoa i te wā me te moni atu i te āhua maamaa o te tauira 3D mai i te timatanga ki te mutunga.

Te Hāngai o te Hoahoa me ngā Here i te Whakaputatanga

• Ngā Here o te Whakauru Paraihe : E hiahiatia ana ngā kōnga tuarangi (1—3°), te nehe tūpui kotahi (0.5—4 mm), me ngā totoiti iti rawa kia kaua ai te māmā i te āhuatanga, i ngā raru whakaputa.
• te Whānuitanga o te Tauira 3D : Ka wehe i te hiahiatanga mō ngā kōnga tuarangi, ka tautoko i ngā nehe tūpui rerekē, ā, ka whakauru ngā waeine maha ki tētahi waeine kotahi.
  Hei tauira, e pāngia ana te hanga mātātoko i ngā araumu roto i te iti ake i te 0.5 mm, ā, ko te tauira 3D ka eke ki te 0.1 mm, he mea matua whaihua mō ngā taputapu mātārere ōrite.

Te Arawhata Mata, Te Pono, me ngā Hiahia Tāwhai-Tuhi

Ko ngā wāhanga i hangaia mā te whakauru hohonu e puta ana mai i te rereketanga o te mata i waenganui i te 0.8 ki te 1.6 miriamita Ra, e ōrite ana ki ngā mea e kitea ana i ngā tikanga mahi. Engari inuia ngā wāhanga i hangaia mā te 3D, ka piki ake ngā tau tōaitanga, e waenganui ana i te 3.2 ki te 12.5 miriamita Ra. Me nui ake te tinihanga muri, pērā i te āta ākiaki, whakamātautau kimihana rānei mēnā ka whakamahia ki ngā wāhi e nui ana te āhua. Heoi anō, kei tētahi wāhi e mārama ai te 3D: mō ngā pāpā tino māmā e pēhia ana ngā kaihanga, ko ngā taputapu 3D e tuku ana i te pono tōaitanga pai ake. Kei te −0.1 mm te nohoanga tōaitanga i te tīmatanga, i te tata ki te 0.3 mm ina whakamahia ngā tikanga rerehua. Nō reira ka nui te hiahia ki te 3D mō ngā tauira tuatahi e hiahiatia ai te pono.

Ngā Kōwhiringa Matērihia me ngā Āhuatanga Mekanikia o ngā Wāhanga Mutunga

Ka whakaaetia e te totohu whakakīnga ngota ngota (hei tauira, mō te kāpara kirikoaki, i te kāpara ārai ahi rānei) mō te pūmau i te ahumahi, i te wā e whai ana te tuhinga 3D i ngā resin noho tahi me te tinana e tino pai ana mō ngā tauira hauora me ngā tanumaero poto.

Te Rangahau i te Rahi o te Whakaputa me te Tirohanga Moni

Te Whakatairanga Moni: Ngā Tini Poto vs Te Whakaputa Nui

Ina hāngai ana ki te whakaputa i ngā wāhanga āta tā, ka pai rawa te ōhanga. Ka heke te utu mo ia wāhanga he nui, kei te rauwaru tekau ki te waru tekau pea rānei ngā huinga ina neke ake te hanga i te tekau mano kaupeka e ai ki ngā raraunga a Finale Inventory mai i te tau ki muri. Ae, he nui te moni e herekia ana i te timatanga mō ngā pāpārahi, heoi anō, ko te nuinga o te wā he tekau miriona tēnei ki te rau miriona tāra, pea hoki tētahi mea atu. Engari, ina piki ake te whakaputanga, ka pakaru te nui o ngā utu tuatahi ki runga i ngā mano wāhanga, nā reira e pai ana tēnei tikanga mō ngā hua e hokona ana tonu, ā, he tino rite te hiahia. I te taha aronga, mēnā e hia waahanga anake e hiahiatia ana, i te tata ki te rima rau mea, ka nui ake te whakapehapeha o te panuku 3D. Ka wātea tino i te tahumaero o ngā pāpārahi utu nui. E āhua i te iwa tekau huinga pea te utu mō ia wāhanga e iti ana i ngā tikanga hanga noa.

Kē aha te wā e kōwhiri ai i te Tā 3D Mā te Tono me te Whānuitanga

Kōwhiria te hangarongo tāpiritanga ina:

• Te whanaketanga i ngā hoahoa kāore anō kia whakamātauria e hiahiatia ana ngā huihuinga maha
• Te whakaputa i te itinga iho i te 1,000 waeine i roto i te tau me ngā tohu e takotorere ana
• Te hanga i ngā āhua herenga herenga e herea ana ki ngā rama matū huaipu maha

I roto i te oratotokorangi, hei tauira, ka whakamahia e ngā kaiwhanake te tā 3D hei hanga i ngā tauira taonga motuhake mō te paitini i ngā wā o te whakaaetanga a FDA i mua i te neke atu ki te tā inu mō te whakaputa katoa.

Kē aha te wā ka tuunga ake te Tā Inu hei Kōwhiringa Pai ake mō ngā Huinga Rawa

Huri ki te tā inu ina:

• Ka neke ake te tono tau i te 5,000 waeine
• Ko ngā īngoa mekameka tūtata i roto i ngā huinga he mea nui
• E hiahiatia ana ngā wā poto (<2 wiki) i muri i te hanga taputapu

Ko ngā kaiwhakarato motuka e whai ana i te peni 40% i te nuinga o te utu ki te tuhi 3D ina hangaia neke atu i te 20,000 ngā waehe o te punaha karaka ia tau, ā, e ai ki ngā tūmanako 2024.

Te tātai i te Pito Taurite mō te Tīpako i te Tikanga Whakanaotia

Whakamahia tēnei wāhanga hei tātai i te rahinga hurihuri:

Rahinga Taurite = (Utunga Taputapu Mātātoko Injekihana) / (Utunga Kotahi Kōpae 3D — Utunga Kotahi Mātātoko)

I te tātai taurite 2023 māwhai i ngā karaihe pāroa ABS i whakaatu ko te piko heke i te 1,150 wae - i raro ake nei ka ekonomik te tuhi 3D, ā, i runga ake nei ka peni te mātātoko $14.72 ia wae. Me whai hoki te whakaaro ki te wā roa: mā te tuhi 3D ka tīmata tonu te wāhi kotahi, engari ka take 8—12 wiki te hanga i te taputapu.
