4.3 Hanyoyin Mai Da Hankali kan Kayan Aiki
Tsarin fitarwa yana farawa da kaddarorin kayan aiki sannan ya koma baya zuwa taswirar bayanai. Misali, amfani da bayyananniyar gishiri a cikin buga SLA don ɓoye yawa.
5. Ƙalubalen Fasaha & Iyakoki
5.1 Girma da Ƙuduri
Injinonin kera suna da iyakataccen ƙarar gini da ƙudurin fasali. Matsakaicin bayani mai ƙima $v$ da aka taswira zuwa tsayi $h = k \cdot v$ na iya wuce iyakokin na'urar bugawa ($h > H_{max}$), yana buƙatar ma'auni mara layi ko rarrabuwa.
5.2 Iyakokin Kayan Aiki
Kayan aiki suna ƙayyadaddun ƙarfin tsari, amincin launi, da kammalawa. Zaɓaɓɓen taswirar launi ƙila ba ta da fil ɗin da ake da shi, yana buƙatar sarrafa bayan kera.
5.3 Taswirar Launi da Siffa
Fassara launin dijital ($RGB$) zuwa launin zahiri (fenti, fil) ba abu ne mai sauƙi ba kuma ya dogara da kayan aiki, haske, da dabarun kammalawa.
6. Nazarin Lamura & Misalai
Misalin Tsarin (Ba Code ba): Yi la'akari da jikance taswirar zafi 2D. Tsarin fitarwa zai iya haɗawa da: 1) Bayanai: Matrix na ƙimomi. 2) Salon: Filin tsayi. 3) Ƙira: Samar da raga na saman 3D. 4) Binciken Iyakoki: Tabbatar da matsakaicin tsayi < Z-axis na na'urar bugawa, mafi ƙarancin gangare > $\theta$ don yiwuwar bugawa. 5) Kera: Yanke samfurin don buga FDM. 6) Sarrafa Bayan Kera: Fenti tsayin da ya dace da kewayon ƙimomi.
Bayanin Chati: Zane na ra'ayi zai nuna bututun: Tarin Bayanai -> Taswirar Gani (Dijital) -> Shirya Siffar Lissafi -> Binciken Iyakokin Kera -> Abun Zahiri. Akwai madaukai na amsa daga binciken iyakoki zuwa shirya siffar lissafi da taswirar gani.
7. Tsarin Bincike & Fahimta
Mahimman Fahimta
Babban bayyanar da takardar ta yi shi ne cewa fitarwa zuwa jiki shine sabon toshewa a cikin jikance bayanai. Mun warware ɓangaren "ganin dijital"; abin da ke da wahala shi ne ilimin kimiyyar lissafi.
