New technologies are being developed every day. Many of these may not make it into the curriculum for technology and engineering students. For those that do, there may be quite a delay between the time the technology is introduced at an industrial scale and when the technology is developed at a relatively low cost and small scale needed to facilitate introduction into schools. This is the story of how one technology that was newly introduced into technology and engineering education laboratories sparked student experimentation. The technology is the additive 3D printing system called stereolithography. But first, the article considers a 3D printing technology that is more common in schools these days, fused deposition modeling (FDM).
