The Tera 250 Micro AM technology introduces a process change that overcomes issues related to the reliance on legacy technologies when seeking to manufacture smaller parts while retaining sub-micron tolerances.
Recently, Nanofabrica produced a reproduction of a DNA helix that has astounded professionals and which exemplifies the 3D printer’s ability to produce parts of mind-boggling size with exacting tolerances.
The DNA helix measures 925 microns in length, and includes tiny features that are impossible to manufacture through micro molding, or that would require the manufacture of expensive micro tools.
The other alternative is to use manufacturing tools that are scaled down versions of macro technologies. These scaled down macro-molding machines have a side effect of material degradation common to all molding processes, (but exacerbated at the micro scale), or use clamping forces and molding pressures in excess of what is needed for micro molding.
This is where Micro AM technology finds its niche. Through the use of the Tera 250, companies requiring miniature plastic parts and components can efficiently, and cost-effectively shift to AM from conventional manufacturing processes. Users can benefit from AM advantages including promoting part complexity with no increase in cost, eliminating the needs for expensive tooling, reducing part counts and the need for assembly, speeding product development time, easy revision of part design, mass customization, reduction in waste, and reduction in energy costs.
