What is Noise in Communication? A broad definition of noise in communication is something that keeps a receiver from completely comprehending a message. Distractions can inhibit a person from offering his undivided attention and may keep him from fully grasping what you are trying to say.
The difference between FDM and PolyJet printing is that PolyJet printing will give you extremely smooth surfaces, complex geometrical structures and precision like never before. Another great advantage that comes with PolyJet printing is that you can use a number of materials in one single prototype.

Fused deposition modeling (FDM) is an additive manufacturing technology commonly used for modeling, prototyping, and production applications. It is one of the techniques used for 3D printing. FDM works on an additive principle by laying down material in layers; a plastic filament or metal wire is unwound from a coil and supplies material to produce a part. The technology was developed by S. Scott Crump in the late 1980s and was commercialized in 1990.
