5 babbar fasahar buga 3D don juya karfe zuwa sassa

---

Bugun 3D galibi ana gane shi ta hanyar na'urar buga kayan fasahar dijital. Ana iya amfani da fasahar buga 3D ta ƙarfe kai tsaye don saurin samfuri na ɓangarorin ƙarfe. Tana da fa'idodi masu yawa na aikace-aikacen masana'antu kuma ita ce mahimman fasahar fasahar buga 3D. Bari muyi la'akari da ka'idojin buga 3D guda uku na NPJ, SLM, SLS, LMD da EBM.

1.SLM (Zaɓi Laser Melting).

SLM shine fasahar samar da Laser fusion na yankin da aka zaɓa. Ita ce fasahar da aka fi amfani da ita a cikin bugu na 3D na ƙarfe. Yana amfani da tabo mai kyau don narke foda karfen da aka saita da sauri, kuma kai tsaye yana samun kowane nau'i da sassa tare da cikakken haɗin ƙarfe na ƙarfe. Fiye da 99%. . Fasahar SLM ta shawo kan rikitaccen tsarin kera sassan karfe tare da fasahar Selective Laser Sintering (SLS).
Laser galvanometer tsarin na daya daga cikin key fasahar na SLM. Mai zuwa shine zane mai aiki na tsarin galvanometer na SLM Magani:

Laser galvanometer	Fitar Laser
Laser watsa	Duban galvanometer

Metal foda narkewa tsari

A cikin aikin 3D na ƙarfe na ƙarfe, tun da yawancin sassa suna da rikitarwa, ya zama dole don buga kayan tallafi, kuma ana buƙatar cire goyon bayan bayan an gama gamawa, kuma ana sarrafa saman ɓangaren.

Buga kayan tallafi	Cire sassan
Karfe tacewa	Tsarin fitarwa lokaci mai ruwa

2.SLS (Zaɓi Laser Sintering)

SLS shine fasahar samar da Laser na yankin da aka zaɓa, wanda yayi kama da fasahar SLM. Bambanci shine ikon laser ya bambanta, kuma yawanci ana amfani dashi don bugu na 3D na manyan polymers.
Mai zuwa shine tsarin da SLS ke shirya sassan filastik:

Shirye-shiryen SLS na sassan filastik	yanki mai layi na samfuri
Samu sassa	Bayan aiki

3.NPJ (Nano Particle Jetting)

Fasaha ta NPJ ita ce sabuwar fasahar bugu ta 3D ta karfe da kamfanin Xjet na Isra'ila ya haɓaka. Idan aka kwatanta da na yau da kullun Laser bugu 3D, yana amfani da ƙarfe na ruwa na Nano kuma ana ajiye shi ta tawada. Gudun bugawa yana da sauri fiye da bugu na laser na yau da kullun. Sau biyu, kuma yana da ingantacciyar madaidaici da rashin ƙarfi.

4.LMD (Laser Metal Deposition)

LMD fasahar gyare-gyaren Laser ce. Fasaha tana da sunaye da yawa. Cibiyoyin bincike daban-daban suna yin bincike daban-daban kuma suna kiran su da kansu. Sunaye da aka saba amfani da su sun haɗa da: LENS, DMD, DLF, LRF, da dai sauransu. Babban bambanci daga SLM shine foda yana tattara ta cikin bututun ƙarfe don aiki. Babban tebur, tare da hasken Laser a wuri guda, foda ya narke kuma ya yi sanyi don samun abin da aka tattara.
Mai zuwa shine tsarin aiki na fasahar LENS:

	Tsarin gine-gine

5.EBM (Electron Beam Melting)

EBM fasaha ce ta narkar da katako na lantarki, kuma tsarinsa yayi kama da na SLM. Bambancin shine tushen makamashin da EBM ke amfani da shi shine hasken lantarki. Ƙarfin wutar lantarki na EBM yawanci tsari ne na girma fiye da ƙarfin fitarwa na SLM, kuma saurin dubawa ya fi na SLM girma. Sabili da haka, yayin aikin gini, EBM yana buƙatar preheat gabaɗayan dandamalin gyare-gyaren don hana zafin jiki daga yin girma da yawa yayin aikin gyare-gyaren. Ku zo zuwa babban saura damuwa.
Mai zuwa shine tsarin aikin EBM:

	EBM yana aiki gabaɗaya dumama
