I loko o ka plastic CNC machining (Digital Computer Control), ua hana ʻia ka ʻāpana e ka mīkini i loko o ka nui o kahi poloka plastik e nā mīkini wili kikohoʻe.Ua kūpono kēia ʻenehana prototyping wikiwiki no ka hana ʻana i nā ʻāpana i ka pōʻaiapili o ka hoʻāʻo hana.
ʻO ka mīkini CNC o nā ʻāpana prototype plastic kahi i kapa ʻia ʻo "subtractive" no ka mea aia ka wehe ʻana o nā mea.ʻO kahi koho nui o nā resins e hiki ke loaʻa nā ʻāpana i ka "mea kūpono", no laila e ʻae ai i nā waiwai mechanical kokoke i ka ʻāpana i hoʻoheheʻe ʻia (ABS, PC, PP, PVC, POM, PMMA, PA 6/66).
