Ọgbọ ndị gara aga nke ntinye ntinye ego:

Isi okwu: na-ewe oge na ọnụ

A na-akpọ nkedo itinye ego n'ihe nkedo wax. Ụzọ mfu wax na China malitere n'oge opupu ihe ubi na oge mgbụsị akwụkwọ ma nwee ogologo akụkọ ihe mere eme.

Ihe nkedo wax na-efunahụ bụ ihe a na-eji waksị mee ka a tụba ya n'akụkụ ya, wee were apịtị kpuchie ihe a na-eme n'ụdị apịtị ahụ. Mgbe ihicha ụrọ ebu, gbazee n'ime wax ebu na mmiri ọkụ. A na-ewepụta ụrọ kpụọ akpụ ụrọ ahụ gbazere wee gbanye ya n'ọkụ.

Ewebata usoro ntinye ego maka ngwa nbipute 3D n'okpuru.

Nzọụkwụ asatọ nke ntinye ntinye ego 3D:

1. CAD Modeling, 3D Printing efufu ụfụfụ

A na-emepụta faịlụ dijitalụ nke ụdị nkedo a wụrụ awụ site na iji sọftụwia CAD, wee bupụ ya na. Ọkpụkpọ STL wee bipụta ya site na iji ngwa nbipute 3D (a na-atụ aro teknụzụ SLA maka ngwa nbipute 3D). Usoro obibi akwụkwọ na-ewekarị naanị awa ole na ole.

2. Lelee ma enwere oghere na ụdị nkedo a wụrụ awụ.

A na-arụ ọrụ polishing elu na ọrụ nhazi ndị ọzọ na 3D e biri ebi iji wepụ lamination elu. Mgbe ahụ jiri nlezianya lelee ma ihe nlereanya ahụ nwere oghere ma ọ bụ mgbawa.

3. Mkpuchi elu

Mgbe ezigara ihe nlereanya ahụ na ebe a na-emepụta ihe, a na-ebu ụzọ kpuchie elu nke ihe nlereanya ahụ na ceramics slurry. Okpokoro slurry kwesịrị inwe njikọ chiri anya na ụdị nkedo itinye ego, na ịdịmma nke oyi akwa mbụ ga-emetụta ogo elu nke nkedo ikpeazụ.

4. Ịgba egbe

Mgbe kpuchiri slurry ceramics, oyi akwa nke ceramics slurry bụ aja viscous. Mgbe ihichachara, megharịa usoro nke mkpuchi mkpuchi na ájá na-arapara ruo mgbe shei ahụ ruru nha achọrọ.

5. Nri na nhicha

Mgbe shei ahụ kpọrọ nkụ, a na-etinye ya n'ime ọkụ ma kpọọ ya ọkụ ruo mgbe ụdị ihe nkedo agbaze niile dị n'ime na-ere ọkụ. N'oge a, shei ga-aghọ ceramik n'ozuzu n'ihi kpo oku. Mgbe e wepụsịrị ya na ọkụ ọkụ ahụ, a ga-ehichapụ ihe dị n'ime ọkụ ahụ nke ọma site na ịsacha, wee kpoo ya ma kpoo ọkụ.

6. Nkedo

Site na ntupu, nrụgide, oghere oghere na ike centrifugal, igwe mmiri a wụrụ awụ na-ejupụta na shei efu wee mee ka ọ dị jụụ.

7. Ngosipụta ihe

Mgbe igwe mmiri ahụ kwụsịrị kpamkpam ma guzobe ya, a na-ehichapụ shea seramiiki n'èzí metal ahụ site na mmaji igwe, nhicha kemịkalụ ma ọ bụ ịgbanye mmiri.

8. Post-processing

Enwere ike tụọ izi ezi nke akụkụ, njupụta na akụrụngwa igwe ndị ọzọ nke ụdị igwe site na ọgwụgwọ elu ma ọ bụ nrụgharị ọzọ.

Enwere ike iji ngwa nbipute SLA 3D nke SHDM mee ihe eji eme rọba site na iji ihe ndị na-adịghị mma na ihe na-eguzogide okpomọkụ. Ọ dabara nke ọma maka nkedo akụkụ site na usoro ọnwụ wax.

Mgbe ebipụchara ihe eji emepụta plastik, a ga-ewepụ ihe ndị fọdụrụ na ntụ ntụ, mgbe ahụ, a ga-eji infiltration wax mee ihe iji hụ na a na-emechi ihe mkpuchi plastik ma dị ọcha iji melite ogo nke ntinye ego.

Usoro ọgwụgwọ na-esote bụ otu ihe ahụ dị ka usoro mmepụta omenala: nke mbụ, a na-ekpuchi mkpuchi seramiiki n'elu ihe mkpuchi plastik, mgbe ahụ, a na-etinye ya na kiln.

Mgbe okpomọkụ gafere 700 C, ihe mkpuchi plastik na-ere ọkụ kpamkpam n'enweghị ihe ọ bụla fọdụrụnụ, nke bụkwa mmalite nke aha usoro ọnwụ wax.

Mbipụta 3D nwere ike ghọta imewe dị mgbagwoju anya ma mee ka itinye ego na-ebu ngwa ngwa, ngwa ngwa na nke akụ na ụba. A na-eji ya n'ọtụtụ ebe n'ụgbọala, ọla, nrụpụta igwe na ụlọ ọrụ ndị ọzọ.
