Electroforming, electrochemical machining, and electrical discharge machining all use electrolytic baths. But only one is additive, which helps explain why it’s also more precise.
Both methods employ photolithography to fabricate nano-scale structures. But where one adds material to exposed surfaces, the other subtracts — with far different results.
For a very long time component makers have widely applied photolithography as the go-to technique for fabricating extremely small features. The tiny circuits in a computer chip are the most obvious example. One reason is simplicity.
Does your product or application call for a very tiny part? If so, nano-scale electroforming may be your best or even your only option. To find out for sure you’ll need to talk to someone with expertise and experience in this highly specialized field of manufacturing. To get that discussion started, here’s some background on the key factors that help determine nano-scale electroforming success.
