A5 Powder bed Printer
A number of people have built powderbed printers, but a lack of detail makes it hard for many to build their own, I hope to build one and explain each step, so that others can follow, using equipment and materials that are off the shelf wherever possible.
The principle of a Powderbed printer is simple, take an existing printer, make it into a flat bed, and mount it above some powder, but as always the devil is in the detail, we have various aspects to make the whole,
Printer
HP DJ1000 HP DJ2050
The HP DJ1000 was the printer of choice for initial development, it looks simple and cheap, and cartridges are refillable, at the time they were difficult to find due to being on special offer, so a HP DJ2050 was purchased instead, this looks like a DJ1000 with a scanner on top, hopefully the scanner will not present extra problems?.
Recoat mechanism
Powder bins and mechanisms
The powder bins are made from 6mm MDF, (£10) to the drawing below, the store cut the parts on a wall saw, this ensures the cuts are square, (no charge for cutting). The centre lines of the cross plates were marked out, and small holes for panel pins drilled, glue the edges and assemble, making sure all sides are as square as possible to avoid tight spots when the pistons are fitted, then tap in the panel pins, (use small pins to avoid splitting the MDF), double check that the whole thing is square, ( clamp if needed) and leave to set for 24 hours, I coated mine with wood stove paint, to seal it against moisture, which may cause swelling and distortion.
