Thank you for all of your excellent information. I have a question, if you don't mind. I am just about to give this a go and this is something that I don't understand. I see that some instructional videos describe how important it is to keep the film absolutely flat as it comes out of the printer, so that the ink does not run. This is usually PET sheets, not a roll. Then I see the roll printers with automated shakers and that film comes out of the printer and goes down vertically to be powdered and whacked with the shaker. So how is the ink not just running all over the place when it's vertical? What am I missing? Is this a function of the type of ink and film? Should I be looking for a specific brand that doesn't have the problem? I think that some of the non-diy printers may have a heated bed under the film prior to powdering, but I didn't see diy-ers on this forum mention that this is needed. Thanks for your help.
