What material are the components?

Prusa i3, v3.06:

I ran into a bit of a problem when attempting to connect the X-carriage-back to the X-carriage. This was step 5. E-axis assembly (Spiral wrap), #43.

The X-axis cracked when I was tightening the x-carriage-back to the x-carriage. 
 
To have the part build locally would you please tell me what process: SLS, FDM, or SLA and what material it should be ordered in? (I did download the STL files)
 
Thank you for any help you can give.

RE: What material are the components?

Some of the MK3 orange parts were ABS, and some are printing black MK3S parts in PETG, and a couple of people have said HT PLA works.  Since the parts are printed by Prusa on Mk2 or Mk3 printers ... I'd guess FDM.  

I'd suggest you use CHAT at the Prusa Store and ask the Prusa support guys what your printer is made out of so you get a good match.

RE: What material are the components?

Prusa prints the parts with Filament-PM PETG Black on Prusa Mk3 (obviously FDM) printers with a 0.20mm layer height at maxed out speed settings. If you apply a little more conservative settings, your part will look better and work better than original. You may also want to add additional perimeters, top and bottom layers and tighter infill. The "Prusa PETG" preset in Slic3r-PE is appropriate for this filament.

And one more advice: Do not overtighten the X back. Be very gentle there. Even if it doesn't crack, too much torque will deform the parts, cause the bearings to be closer together than the rods, which will result in more resistance and may eventually damage the rods.

@ Voj - my MK3 is orange ABS, Voj. At least that's what Prusa told me.  Maybe the guy on Chat duty was an idiot ... but that's what he said.

He was probably right. Initially MK3's were done all in ABS. Later Prusa switched to PETG for everything but the print cooling fan shroud. The shroud needs to be ABS for temperature resistance. And of course, there's also Filament-PM Orange PETG for the orange parts.

See Prusa i3 Printable parts.
