Introduction

The multifunction printer module have a structure cartesian of 3D printers.

Since my childhood, my dream was to do make a robot. And a thirty age i did it succeeded. The my first robot "completed" is it a 3d printer with double extrusion nozzle and a cartesian structure. This 3d printing is composed to a two motors for Y and X axis, two motor for filaments and two motor for Z axis for balancing force during the movement. Also use a one hot plate. For the structure I have using the aluminum profiles. For all the control to 3d printing I have used a board Arduino DUE and RADDS shield using a Repetier Firmware and have a one Raspberry Pi for the remote control with Octoprinter Software.

The main goal of MPM is to create custom objects and print many other parts with a simple download. For example, my son is very happy to play with many downloadable toys on Thingiverse

To make the 3d printer, I made an effort in every night for six months. But the best reward is always to see it work

NOTE: Many alternatives exist to the standard Prusa RP parts. Head over to RP alternatives to check out other options. If you are just getting started with reprap, it is recommended to use the standard BOM of RP parts to keep life simple.

Non-Printed Parts ("vitamins")

Note that additional parts are required for the extruder, although some extruder parts are included in the table below.

Required

Quantity	Description	Type	Comments
83	M8 nut	Fastener	Buy a 100-pack to be on the safe side.
93	M8 washer	Fastener	Buy a 100-pack to be on the safe side. (Grade 2 works fine.)
6	M8×30 mudguard / fender washer	Fastener	These are also known as penny washers, they have a much larger outer diameter than regular washers.
2	M4×20 bolt	Fastener	To mount the extruder
2	M4 nut	Fastener	To mount the extruder
2	M4 washer	Fastener	To mount the extruder
22	M3×10 bolt	Fastener
16	M3×25 bolt	Fastener	Or eight M3×25 bolt plus eight M3x20 bolts. The M3x25 bolts are too long for the recent Prusa z-motor-holder and rod-clamp, and also for the Z motor couplings. See Section 8, steps 4 and 13 for details.
4	M3×40 bolt	Fastener
70	M3 washer	Fastener
40	M3 nut	Fastener	8 optionally locknut / stop nut / nyloc
2	M3 grub screw / set screw	Fastener	M3x8 seems about ideal but anything 6mm or longer should do. If these are hard to get, additional M3×10 bolts will do the job instead.
3	608 roller skate / inline skate / skateboard bearing	Bearings	You don't need to ask for a "608 bearing" at a skate shop, just ask for wheel bearings.
4	ballpoint pen springs	Spring	To fit over M3 bolts. Ballpoint pens are a common, cheap source of suitable springs. They are about 25mm long and compress to about 10mm.
6	M8×370mm	Threaded rod	3 per side Note: The threaded rods can be cut from larger 6x1m pieces (see Threaded Rod Cut Order below).
4	M8×294mm	Threaded rod	front / rear
3	M8×440mm	Threaded rod	top / bottom
2	M8×210mm	Threaded rod	Z-leadscrew
1	M8×50mm	Threaded rod	or M8x30 or longer bolt for X idler. Take care: if the bolt is too long, it may not be threaded along a sufficient length
2	8mm×420mm	Smooth rod	X-bar Note: 304 Stainless Steel, A2 Tool Steel, or O1 Tool Steel are recommended for smooth rods as it can help to prevent friction from rust and manufacturing (straightness) standards are higher. Rust issues can be prevented on the normal steel rods by maintaining a coat of oil. The smooth rods can also be cut from larger 3x1m pieces (see Smooth Rod Cut Order below).
2	8mm×406mm	Smooth rod	Y-bar
2	8mm×350mm	Smooth rod	Z-bar
1	225mm×225mm print top plate	Thick Sheet
1	140mm×225mm print bottom plate	Thick Sheet	Note: The Prusa Iteration 2 design does not use a print bottom plate.
1	840mm×5mm T5 pitch timing belt	Belt	Y axis
1	1380mm×5mm T5 pitch timing belt	Belt
5	NEMA 17 bipolar stepper motor	Motor
50	small cable binder / ziptie	Consumables	or other cable management
10	8mm Linear Bearings - LMU88	Bearings
