Ib txwm ua cov cuab yeej siv tau maj mam hloov los ntawm kev ua haujlwm ntse tshiab. Lub tswv yim txawj ntse ua technology tsis tsuas yog txuag lub sij hawm, tab sis kuj plays lub luag hauj lwm nyob rau hauv kev tswj nqi. Tshwj xeeb tshaj yog nyob rau hauv thaum ntxov hnub ntawm pwm, sai prototyping technology yog maj tau lug siv.
Rapid prototyping (RP) thev naus laus zis yog kev tsim khoom siv thev naus laus zis tsim tawm hauv xyoo 1990s. Nws yog ib qho tseem ceeb generic technology pab txoj kev loj hlob ntawm cov khoom tshiab rau kev lag luam. Nws ua lub luag haujlwm zoo hauv kev txhawb nqa kev lag luam cov khoom lag luam tshiab, ua kom lub voj voog kev loj hlob ntawm cov khoom tshiab, thiab txhim kho cov khoom sib tw. Txij li thaum cov thev naus laus zis tawm los, nws tau siv dav hauv kev tsim khoom ntawm cov teb chaws tsim, thiab kev siv tshuab tshiab tau tshwm sim.
RP thev naus laus zis yog kev koom ua ke thiab tsim los ntawm lub hauv paus ntawm niaj hnub CAD / CAM thev naus laus zis, thev naus laus zis laser, tshuab computer lej tswj tshuab, precision servo tsav tshuab thiab cov khoom siv tshiab. Cov txheej txheem sib txawv ntawm cov txheej txheem sai sai muaj cov qauv sib txawv thiab cov yam ntxwv ntawm cov txheej txheem vim muaj cov khoom sib txawv. Txawm li cas los xij, lub hauv paus ntsiab lus tseem ceeb yog tib yam, uas yog, "txheej txheej tsim, txheej txheej txheej", zoo ib yam li cov txheej txheem kev ua lej. Visually hais lus, lub prototyping ceev ceev yog zoo li ib tug "stereo tshuab luam ntawv".
Nws tuaj yeem lees txais cov ntaub ntawv tsim khoom (CAD) ncaj qha yam tsis tau npaj cov pwm, cov cuab yeej thiab cov khoom siv, thiab tsim cov qauv, pwm lossis cov qauv ntawm cov khoom tshiab. Yog li ntawd, kev nce qib thiab kev siv ntawm RP thev naus laus zis tuaj yeem txo qhov kev loj hlob ntawm cov khoom tshiab, txo tus nqi tsim kho thiab txhim kho txoj kev loj hlob zoo. Los ntawm ib txwm "txoj kev tshem tawm" mus rau niaj hnub no "txoj kev loj hlob", los ntawm cov qauv kev tsim khoom mus rau kev tsim khoom tsis zoo, qhov no yog qhov tseem ceeb ntawm kev hloov pauv ntawm RP thev naus laus zis rau kev tsim khoom lag luam.
