BFB 3000 Operations manual

Overview of the printing process.

BFB 3000 prints solid objects by laying down successive layer of plastic. It first draws an outline of the layer and then fills in

the middle as required, much like you would colour in a drawing. After doing one layer it moves on to the next layer by

lowering the print platform a small amount and draws the next layer on top of the one before, thereby building a solid object.

The layers are typically 0.2mm thick but can be varied to suit the application.

BFB 3000 gets its information of what to print from an SD card inserted in the left side of the controller. This contains a G

code file that tells the machine what to do. G code is a simple text file that has co-ordinate instruction and other commands

to control the BFB 3000. For more information on G code please see http://en.wikipedia.org/wiki/G-code. The BFB 3000

does not support all G codes and has a few special ones of its own, these are explained in detail later. The G code is

generated using either Netfabb or BFB’s customised Skeinforge conversion software, this application takes a 3D model and

generates the G code file which is then copied to the SD card. Netfabb or BFB’s customised Skeinforge reads various file

types but the commonest being STL which can be output by most 3D CAD packages and has become the standard for 3D

printing/rapid prototyping. The G code file must follow the 6.3 naming convention i.e. “Test01.bfb” the BFB 3000 will only

read *.bfb & *.gco files all other file extensions will be ignored.
