Interesting product. I especially take note of the design of their “light engine”, which looks pretty much like a direct ripoff of the Form3 design… [https://www.kickstarter.com/projects/emake3d/galaxy-1-the-17-large-scale-sla-3d-printer](https://www.kickstarter.com/projects/emake3d/galaxy-1-the-17-large-scale-sla-3d-printer) ---

Their light engine looks very much like a classic laser printer scanner unit with a polygon mirror, so it will probably have the same issues with sharpness at the edges. [![](https://upload.wikimedia.org/wikipedia/commons/3/30/Laser_printer_canner_unit.jpg) ](https://upload.wikimedia.org/wikipedia/commons/3/30/Laser_printer_canner_unit.jpg) As far as i understand the F3 laser unit was designed to avoid that, the beam is always perpendicular to the build surface: [![](https://formlabs-media.formlabs.com/filer_public_thumbnails/filer_public/58/b9/58b92607-91ee-423a-9e11-7369f3480573/formlabs_lazer_finalstill.jpg__1354x0_q85_subsampling-2.jpg) ](https://formlabs-media.formlabs.com/filer_public_thumbnails/filer_public/58/b9/58b92607-91ee-423a-9e11-7369f3480573/formlabs_lazer_finalstill.jpg__1354x0_q85_subsampling-2.jpg) Also there is very litte information about the vat on the Kickstarter page. Big bottom-up SLA systems always have issues with adhesion forces. As far as i can tell the part cross-sections in the demo prints aren’t that big. Edit: Actually the box shaped print seems to have substantial cross sections, so maybe the machine can deal with that issue. ---
