I’m working on a MEMS problem. I need to be able to 3D print micron (or even sub micron) scale features for a very high aspect ratio MEMS which uses electromagnets to actuate. Only problem is the leading candidate technology EFAB (electrochemical fabrication) only works with conductive materials.
Does anyone know of a technology which provides similar abilities to EFAB but can also print features with non conductive materials?
- fbeutel 5y agoWould something like Nanoscribe [1] work for you? The resulting structures are non-conductive. As part of our research we use it mostly for 3d-printing nanoscale optical elements, but we have also successfully used it for some mechanical support structures.

- Const-me 5y agoNot sure it gonna help, but some DLP 3D printers are very accurate, and most resins are non conductive. I know researchers were using one for micro-fluids applications. Not sure they can print sub-microns precisions, but 10μm is very real.
- mikewarot 5y agoCould you use a conductive material, then deposit an insulating coating on top, or oxidize the material on top, making it an insulator? Aluminum can be anodized, then sealed. As can a number of other metals.
