Disɛmba 17, 2021

Rapid prototyping na tin we dɛn kin tɔk bɔt as tin we layn spid de du. Ɛnibɔdi we dɔn rɔn bil no se bɔku pan di wet kin apin ɔdasay — insay aprɔval, insay matirial, insay riply.

Yu De Wet fɔ Matirial, Nɔto di Layn

Menshɔn rapid prototyping ɛn bɔku pipul dɛn kin pikchɔ wan fast layn. Insay prɔsis, wan kɔvɛnshɔnal bil kin tek tri to sɛvin dez ɛn di bɔtulnɛk nɔ kin bi mashin tɛm: wan ɔ tu de fɔ wan kot, wan de fɔ kɔnfɔm di BOM, tu ɔ tri dez fɔ wet fɔ di matirial fɔ kit, dɔn fɔ schedul ɛn tɛst. Di layn insɛf kin rɔn wan bod insay tɛn minit. Bɔku pan di tɛm we dɔn pas kin go fɔ wet fɔ kɔnfɔmeshɔn, fɔ pat dɛn, fɔ ansa.

So fɔ kɔmprɛs wan bil insay fayv awa nɔ kin bigin wit di mashin dɛn. I kin bigin wit fɔ pul di wet dɛn. Kot fɔ bi frɔnt-lod, matirial fɔ de na di shelf, ɛn di layn fɔ de ɔnda yu yon kɔntrol. If ɛni pat pan da chen de stil de wet pan pati we de na do, fayv awa na ɛmti klem. Na dat mek bɔku faktri dɛn nɔ kin ebul fɔ kot di nɔmba — dɛn ikwipmɛnt fast inof, dɛn disizhɔn chen nɔ fast.

Kot fɔs: fɔ muv wan disizhɔn frɔm dez to wan

Di fɔs blɔk fɔ bil fɔ fayv awa na di kot. Yu kin sɛn drɔin ɔ wan sampul rikwaymɛnt, ɛn wan sɔlv ɛn prayz kin kam bak insay twɛnti-fo awa. Ɔltin afta dat dipen pan dis step. If kot tek tri raun na tu dez ɛvri wan, no amɔnt ɔf layn spid nɔ de shɔt di tɔtal.

We yu lod di kot na di frɔnt, i kin chenj ɔda tin bak: i kin fos di faktri fɔ rid di prɔses fayn fayn wan ali. Us matirial go substitute, if di bod gɛt manufakchurabiliti prɔblɛm, aw di stensil fɔ opin — ɔl dat bɛtɛ fɔ sɛtul na di biginin pas fɔ diskɔba na di layn. Wan gud pat pan di tɛm we dɛn sev insay fayv awa bil, dɛn kin rili sev na di kot stej.

Material sekon: stok pat na wetin mek am rial

Di sɛkɔn blɔk na matirial. Sampling de slo we dɛn bay pat dɛn ad hoc — fɔ fɛn distribyushɔn, wet fɔ kɔriɔ, fɔ chɛk if na tru. Faktri dɛn we de wok te to di awa kin kip di kɔmɔn komponent dɛn na stok, pul dɛn na di shelf, ɛn ful-ɔp bak afta di wok. Notin novel in dat, bot i tai op kapital and kari di risk of stok go obsolete as pat nomba de muv on.

I fayn fɔ tɔk di bɔda ɔnɛs wan. Stɔkin nɔ kin ebul fɔ kɔba ɔltin. Ɛni faktri fɔ wet fɔ divays we rili nɔ klia ɔ we dɛn jɔs pul. So fayv awa bil gɛt difayn skɔp: kɔmɔn bod, kɔmɔn pat, machɔ prɔses. If di dizayn nɔ kɔmɔn, di rial ɛkspɛkteshɔn na twɛnti-fo awa, nɔto fayv awa. If yu sɛt da bɔda de bifo tɛm, dat kin sev mɔ tɛm pas fɔ ɛksplen am afta dat.
