Gizmo 3D will Kickstarter-Kampagne im September starten
Nachdem das Unternehmen Carbon3D vor kurzem ein Verfahren vorgestellt hat, das den 3D-Druck deutlich beschleunigen soll, legt nun Gizmo 3D nach.

Super Fast 3D Printer Printing (Continuous printing 50 micron Z (30mm in 6 minutes))
After seeing the video from Carbon3D where they print fast on a bottom-up 3D printer I thought I could probably do the same with the top-down printers from Gizmo 3D Printers.
I am not sure how wide the projection area is that Carbon3D has in their videos. There is enough space for 6 skeletons in my projection area, but the laptop I am using doesn’t have enough memory to handle slicing the 6 skeletons so I am only displaying 3. With more memory it will be possible to produce an object around 150mm x 80mm x 26mm tall in 6 minutes.
I believe if I reduce the projection area by moving the projector closer to the resin the time can be reduced even further, but at the expense of projection area.
Continuous printing will most likely not work for big flat surfaces. The reason why it is working for the skeletons and things like the Eiffel tower is because the wall thickness is very thin or there are very small features. If you do want to print big flat surfaces you have two choices. Slant the object and add supports or add a wiper when printing top-down. When printing bottom-up you probably always have to slant the object, because of suction forces. Top-down printers will most likely be faster than a bottom-up when printing big flat surfaces even if the top-down uses a wiper to help with printing big flat surfaces, because the object doesn’t need to be slanted. Also no supports is needed if the object isn’t slanted so less resin used and less clean up time.
