One layer per second or even quicker !!!
When we could be able to see this kind of speed?
Think like a photocopier (60 pages min and more) and the electrostatic way to manipulated powder (toner) and depose it on a shit of paper before heating. Well I am surprised to not have seen similar process to build a 3D object, with up side down construction to allow over hang and empty object (no powder enclosed or need of a gap like with other process).
are you tempted by a 1000 layers design in less than 15 mn ? :-))
I am not sure but that could be the way HP went on.
What do you think ? (300/600 dpi, in color, low cost laser printer, carbon material, etc …)
What article is this from?
most of it from my thinking, my knowledge of repairing laser printer, and reading between lines about HP official communication.
There us a printer that works like thus. 3d systems makes it.
That technique is called “Laser Sintering” generally. Mostly used in metals but can be use in plastics as well. If you are trying to pick up the build material on a drum and then rolling it over the build to be transferred, you need a material where you can change the potential on the ‘part’ to be more attractive than the drum. Unfortunately that doesn’t work with existing toner systems as the toner has to stay neutral with respect to charge to avoid clumping.
I don’t think the drum is needed - but maybe the scanning system the laser printer uses to expose the drum. However, it would take a lot of power run a laser to fuse that much plastic that quickly.
