Print is not completely finished, but it is already time for a feedback. I do not know if the case will be strong enough (I have not the habit to print using only 1 shell… even less with no infill), but the filament problem is almost completely resolved. The only parts that will need some clean up are the overhangs, which is obvious considering the way it prints using corkscrew printing mode.

The print is good but some tiny holes remain.

At this point, I am wondering a thing… How can I say that my nozzle needs to be cleaned / changed?

22

The case NEVER went totally printed… It seems that the filament slipt at a time of the print for an unknown reason.

I cleaned my nozzle with a 0.4mm guitar cord… When loading the filament, it is smooth.

I launched another print with these parameters except for the speed. I put 1200mm/min. I also changed material and case model.

At this time, I really do not know from where come all my problems.

From my point of view, it could perhaps be:

  1. Filament quality? (did not test the Fairphone branded case in another color)
  2. Room temperature (it is quite cold in the printer room)
  3. Dusty grip (would explain the last print, but not all the others)

Is there someone who could have a clue for me?

I’ll tell you tomorrow if my Day 1 yellow case printed well.

Thanks

I used Rectilinear infill. I am now using corkscrew method… which is not giving me results: the filament slips on the grip when printing the second hole of the case and the case is never printed out completely.

24

The Day 1 case had exactly the same problem: the filament did not grip when printing the second hole and the case never went out completely.

So… this is not the material nor the nozzle nor the model of the case.

PLEASE… HELP… ;-/

Does somebody could provide a working x3g for a Day 1 or branded case so I can test from where is the problem?

@GloomySparker sounds like a feeder issue … sorry I don’t know your printer that well - worth asking on specific forums for that printer - it was a makerbot rep 2? - have you done the extruder upgrade? - I hear once they have that upgrade then they are quite reliable. But slipping filament means that you are probably not quite getting the full throughput and there is no reason that the fairphone case would make it slip more than any other - except that the flow is fairly slow/small and so MB are slightly prone to heat creep on the filaments - some people blow a fan across the bed to cool down the hotend.

As I say - one for the MB2 specialists.

Hey there Fairphone guys,

Franky (@jianghan_mao) just installed the new software for Makerbot and is wondering how to best print Fairphone cases with it. Have any of you already printed Fairphone cases with the new software? Any tips?

Best, Luuk
