7. FILAMENT
BCN3DR achives its best printing results with PLA, ABS andy Nylon, while accepting many other plastic materials in
3 mm filament format.
A brief description of the materials currently accepted follows:
PLA
PLA (polylactic acid) is the quintessential material for 3d printing, thanks to its ease of use through deposition. It is
recommended to begin in this type of manufacturing technology with this material. A great variety of colors exists
and complex geometries can be achived without great difficulty. The finish is slightly glossy or semi-matte.
Printing is carried out at temperatures ranging between 195º and 220° C, depending on the supplier of the material
and printing speed. A layer fan is required to build overhangs. It easily attaches to the glass, and if you work at a
hotbed temperature ranging 45º C-55º C, no product is requiered to ensure this adherence.
The mechanical properties are average, but presents a certain fragility in parts requiring deformation, from a tempe-
rature of about 50 °, the parts can present it. It is dissolved in caustic soda.
8. FIRMWARE
What is a firmware and when to update it?
The firmware is a software needed to control a hardware. Namely, it is the internal program that controls your
BCN3D +, and allows it to perform its functions normally. The BCN3D + is delivered and installed with the latest
firmware version published on the web.
Its basic functions are:
On the one hand, converting .gcode files to useful instructions for printing, managing the motor drivers and target
temperatures.
On the other hand, it is also responsible for managing machine peripherals such as the screen, allowing you to inte-
ract with it without connecting the printer to a computer, or the endstops necessary for proper functioning of your
printer.
Usually the firmware of a device is integrated in it and you can not change or replace it unless aproved and provided
by the manufacturer.
The advantage of our RepRap printer is that it follows the Open Source philosophy so we can change or modify the
firmware to adapt our machine to new features and accessories or improve its behavior.
The ability to modify the firmware is the responsibility of each user. RepRapBCN will always develope firmwares
oriented to printing with their products and will freely disseminated them.
