Software - Fusion Deposition Modeling, FDM

 
Similarly to what I'm doing to software, I'm going to build a list of various fabrication techniques on this blog. The first one I'm focusing on is FDM, or Fusion Deposition Modeling. Similarly to what I'm doing to software, I'm going to build a list of various fabrication techniques on this blog. The first one I'm focusing on is FDM, or Fusion Deposition Modeling. Usually my explanation is, "it's a machine that deposits abs plastic and then fuses it as the bed on which it is printing moves down." I know defining things with the same words is kind of lame, but, in this case, I think it makes it a bit clearer. Also, we have one of these machines at work. For the most part, the resolution on the machine we have is pretty good. One of the draw backs, however, is the speed. The machine prints at a decent speed, but for complex part you have to soak them in a solvent to dissolve the support material. This post is a work in progress so please feel free to post comments.
 
Technology : FDM Fusion Deposition Modeling
Materials : ABS Plastic
Resolution : Since it varies based on the machine I will write very general specs and if i get specific i will site the machine
Speed : Machine dependent - That being said, the machine at our office does about an inch every 2 - 3 hours.
Support Material : Break away and Water Soluable In this you video from Stratasys you will get a sense of what the machine outputs:
