Direct AIM was developed by 3D Systems to create a mold directly by stereolithography. A special stereolithography build style
is used. (AIM stands for ACES Injection Mold and ACES is an acronym for Accurate Clear Epoxy Solid.) The method is useful to
manufacture short run or prototype quantities up to approximately 50 pieces of small, less complex thermoplastic parts.
Depending on the part geometry, it may be necessary to back the mold with epoxy to provide strength. The molds typically require
secondary finishing operations before use to removes stair-stepping and improve finish.
Molds made using Direct AIM are used in injection molding machinery, but here again the parts fabricated won't be identical to
those created in a high volume mold. Cycle time must be considerably longer due to the poorer thermal conductivity of the material
compared to metal, and lower pressures must be used to accommodate its lower strength. Glass-filled plastics aren't recommended
and its very important to study the limitations of the process as it applies to the specific application.
