Testing a BfB3000 with dual extruders
So let's see what this printer can do...
The BfB3000 looks much more "well-finished" than the Rapman3.1.
The main differences that I can notice are :
- allready built up machine (no kit)
- much stronger metal structure
- metal angles rather than acrylic
- Z motor moves the bed with only one rod (no belt)
- each Y belt has it's own motor
- PCB is well protected
- extruder heads are more compact
- up to 3 extruder heads can be mounted
- filament reels are horizontal
- X, Y and Z stops are magnetic sensors
- printer is enclosed in an acrylic bounding box
It's an easy task. You just have to print a calibration file and mesure the distances in X and Y to find out what are the X offset and Y offset values. These values must then be used within Axon's profiles.
After that calibration was done, I decided to have a test with 2 different materials :
ABS for the printed part and PLA for the raft/support.
The object I plan to print is this one :
I found out that printing with double heads leads in much longer print time than with a single head.
That print took about 12 hours to complete (the object is about 15cm high).
Despite a warping excess at the tip of her knees and a few defaults, the printed girl looks quiet correct.
Here it is with and without the PLA support :
