What is 3D Printing?
3D Printing Technology, technically acknowledged as Additive Manufacturing (AM) or Rapid Prototyping, is a manufacturing process in which layers of material are built up to create a solid object.
What is FFF technology?
At BCN3D we design and manufacture desktop FFF 3D printers. Fused Deposition Modeling (FDM), or Fused Filament Fabrication (FFF), is an additive manufacturing process that deposits a thermoplastic material layer-by-layer in order to build a part. This technology manufactures strong, durable and dimensionally stable objects with a great accuracy.
Among the multiple 3D Printing technologies in the market, FFF is the most widely spread because of several reasons. First of all, both the hardware and material are affordable, requiring a low initial investment. Secondly, there is a large range of materials available (such as Nylon, TPU, PET-G or ABS, among others), so the technology is suitable for multiple applications and markets. Finally, the design criteria needed and equipment operation are simple enough, especially compared with other 3D Printing technologies, so there is no need for specialized operators or complex training.
What is IDEX technology?
The BCN3D printers are equipped with a unique double extrusion architecture: the independent double extrusion system (IDEX), the only extrusion system capable of printing with two heads independently.
Reliable dual extrusion 3D printing with IDEX technology
Because of the manufacturing strategy, sometimes it is required to build auxiliary support structures for those models with overhangs shallower than 45° from the horizontal plane.
In the case of printers that only have one extruder instead of a dual extruder system, once the model is printed, it is necessary to perform a manual and time-consuming operation to remove the supports. This process affects the quality surface between the model and the supports and also increases the chances of breaking the part. In addition, depending on the geometry of the model it can be impossible to totally remove the supports by hand.
However, BCN3D proposition uses IDEX architecture to counteract the described disadvantage. IDEX architecture is the most reliable and neat solution on the market when it comes to dual extrusion technology. This is because the two extruders work independently when printing water-soluble supports or multi-material parts. While one extruder is printing the second one is parked, preventing the drip of molten plastic into the part. Conventional dual extrusion printers have both extruders together, which may result in filament threads left on the piece.
IDEX technology: Same investment, double productivity
IDEX is the only extrusion system capable of printing with two heads independently. This system allows enabling Duplication and Mirror printing modes capable of printing two pieces at a time. Double printing capacity means double productivity, all with the same investment. Unlike any other dual extrusion machines on the market, when you acquire a BCN3D machine, you get one printer but you double your productivity. All thanks to the IDEX technology.
