Prusa Mendel Documentation


Prusa Mendel je Ford Model T za 3D printere.

Kao i Model T, Prusa Mendel unapređuje prethodni dizajn kako bi bio jednostavniji za izradu. Prusa Mendel je jednostavnija kombinacija izvornog Mendel. Standardno, koristi isprintane vodilice umjesto standardnih ležajeva, a kao opcija mogu se koristiti i lm8uu linearni ležajevi ili drugi tipovi ležajeva ili vodilica koje su dostupne. Standardna verzija koristi tri 608 ležaja ukupno, jedan za X os i dva za Y os. Ležajevi 624 se više ne koriste.

Prusin osnovni cilj je biti najjednostavniji 3D printer koji možete izraditi:

  • It's much simpler to build it.
  • It's much simpler to modify it.
  • It's much simpler to print it for your friends.
  • It's much simpler to repair it.

Zbog svoje složenosti, Prusa Mendel može se smatrati živim bićem. Može se konstantno unapređivati. Njegove jedinstvene karakteristike trebale bi postati standardne. We are living in feature, we don't care if it's a bit different every time; our printer will print it in same time ;-)


  • Printed Parts: 45 (extruder drive included?)
  • Non-Printed Parts: 388
  • Material Cost: ???
  • Cost: ??? (assembled)
  • Printing Size: 200mm x 200mm x 100mm (8.2" x 8.2" x 4.1")
  • Precision: ??? (position), ??? (printing)
  • Speed: ??? (position), ??? (printing)

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.

Dodatni dijelovi su potrebni za ekstruder, iako su neki dijelovi ekstrudera uključeni u tablicu u nastavku.

Quantity Description Type Comments
83 M8 nut Fastener Buy a 100-pack to be on the safe side. M8nut.jpg
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
