Improvements over the standard Prusa i3

  • The frame version is based on V2.5 with a lot of improvents.
  • Frame compatible with 8mm lead screws.
  • Stronger frame due to the use of structural steel.
  • Solves the frame flexing thanks to its reinforcement squares.
  • Simplifies the construction, eliminating the complex subframe of threaded rods in the Y-axis.
  • Once assembled, everything is in place. No adjustments needed.
  • Less printed parts.
  • The steel mounts for motors and rods are much stronger than their plastic counterparts.
  • Only two threaded rods needed are the ones for the Z-axis (5mm or 8mm)
  • Uses shorter smooth rods lowering the build costs.
  • Solid structural unit that can be transported as a block.
  • The interference between the Y stepper and the M3 nyloc nut holding the Y stepper support has been solved by stretching the support by 2mm.
  • Filament spool holder made in steel S235JR
  • Holes to mount the power supply on side of the frame.
  • Holes to mount the Arduino or SAV on side of the frame.
  • New bolt fix the Z axis smooth rods.
  • Compatible rods: prusa steel rods
  • Our frame use metal parts so is more robust than extrusion metal frames like AM8 for anet A8
  • Only the Orballo Printing frame fully compatible with MK42 heatbed.

Assembly manual (in progress) 

Since July 2017 the P3STEEL frame is fully compatible with the hot bed MK42 ! and the magnetic hot bed MK52!We upgraded the main frame. Now it is bigger and it is able to accommodate the new bed MK42. The dimension of the rods remains the same. The frame it is fully compatible with the previous hot beds MK2, MK2B, MK3 like Anet heatbeds.

You can add the hardware kit for the frame, available in black or stainless steel:

In the top of Z axis is possible use our MR128 bearing for fit the 8 mm leadscrews correctly. Or use MR125 bearing for M5 threathed rods. This solution is improve the precission of the movemente.

The z smooth rods is also fit correctly with a bolt.
