Have you seen what the new cheap SLA machines can do? Several ~$500 machines out now with 47 micron X-Y resolution, using phone LCDs for the UV mask. Wanhao D7, Anycubic Photon, etc. Not sure if it's quite good enough for watch movements but they're certainly capable of much finer details than any FDM machine including the very expensive ones. In principle they should even be capable of finer details than the $3500 SLA Form2 which has 140 micron laser spot size.
- zokier 9y ago> Have you seen what the new cheap SLA machines can do? I'll have to admit, I haven't seen what the state of the art is like. I did some googling of the printers you mentioned and the level of detail is pretty impressive (although most reviews were printing pretty figurines instead of engineering applications), so maybe 3D printing watch movement is not that far fetched after-all. That being said I'd still be quite impressed seeing a 3D printed watch movement. Even more so (and this is moving the goalposts) if the movement ran whole day on a single winding, demonstrating good meshing and low friction.
