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.
For FDM, you will routinely replace. build trays (or sheets) and extrusion nozzles. However, these are. less expensive than the sophisticated printheads that are replaced. after 2,000 hours (or more) of PolyJet 3D printing. Also, the total material cost per cubic inch of part is less with FDM.
