Building a 3D printer from used $60 US flatbed scanner.
MICROTEK ScanMake 9600XL, large format flatbed scanner. Used, purchased at REPC for $60 in Seattle. This will be used for the bases of the 3D Printer I am building. Primary advantage, this scanner has two scanner slide assemblies, bed and lid, complete with stepper motors, belt drive, dual slide rails. Thus, mounted in the appropriately fabricated superstructure, these components can form the primary basis for the x and y axis for the printer.
X and Y Axis
Disassembled top and bottom of scanner and tore out the guts to get at the slide mechanisms.
Maximum length and width of printer set by travel of bottom and lid of original scanner. This will determine the size of the wooden superstructure for the printer.
Scanner Stepper Motors
The stepper motor from the bottom of the scanner. Y-axis, is a TECO, TYPE 4H4018X1603, 5V, 1A, Holding Torque-1.2Kg-cm (Bi-POLAR) X-axis, is a TECO, TYPE 4H4018X0101, 12V, 0.23A, Holding Torque-0.8Kg-cm (Uni-POLAR)
Wood Superstructure
Wood superstructure constructed of 2X4s with a bottom of 3/4" plywood. X-axis from the scanner is mounted in the vertical stand. The Y-axis sets in the bottom of the structure. Both bottom and lid slide systems have only one bushing connected to the rail. This is fine for the the Y-axis because gravity is your friend here. For the X-axis mounted in the vertical a nylon stay was glued to the unattached rail to secure it.
Z-axis
Z-axis will have to be fabricated independent of original scanner. First, a piece of 3/4" plywood was fabricated to mount the X-axis rail system. Z-axis will slide along a center mounted drawer slide (Rockler Center drawer slide, $8.49) .
