This is a Bill of Materials for the kit we offer. It is similar to the Prusa Iteration 2, with a few changes. The x-ends we use are not push-fit, they go all the way through and are held in with a cap screw on each end. We use a different endstop holder to get a little more printing area. We use different z-couplers, they look and work better. We include belt-guides for the belt to ride on instead of just the bearings. We include holders for the RAMPS electronics and to hold a spool of filament on top. Here is what you need:
HardwareThe frame consists of threaded rod for the main supporting structure of the frame and round/smooth rod for the axis to travel on. There is also some threaded rod used to drive the head up and down as well as a small piece to be used as an idler on one end of the x-axis belt. Overall the rods that you need for the frame are:
RepRapped PartsThese are the parts that are created by another 3D printing machine. The parts that a replicatible. There are many variations on these parts, but we aim to mostly provide the standard parts. Unless you kow someone that has a RepRap, you cannot source these parts locally. These are the parts that are needed:
ElectronicsThis is one of the hardest sections to source locally, but could technically be all put together by you. We use RAMPS which is a shield that goes onto the top of an Arduino. Don't be confused by the term shield, it basically just means it plugs onto the top of it. Down the line we may offer support for more types of electronics. The electronics is what drives everything. It communicates to the computer and recieves the GCODE that drives the machine. It has stepper drivers that plug onto it which drive the motors to move everything around and squirt out plastic. It also controls the current going to the hot end/extruder and the heated bed after monitoring the temperature with a thermistor. I will write up a component list to assemble RAMPS 1.4 down the line, but for now I'll provide the electronics. Unless you know how to solder, you probably don't want to assembly this part of the electronics yourself. Fully assembled kits are available. These are the required electronics:
ExtruderVarious types of extruders are available or you can just make your own. The most common/standard version of the cold end is called the Wade's Extruder and is what we currently use. We currently also use Makergear hotends. It consists of:
BedA heated bed is pretty much a necessity if you want to print out any of the larger sized parts. This list of materials includes all that's needed to have a heated bed.
