 +====== 3D Printing ======
  
 +===== About =====
 +
 +==== FDM ====
 +
 +[[kb:theory:mfg:3d_printing:fdm|FDM printing]] is excellent for prototyping parts quickly. I can print a model of your project much more quickly and cheaply than machining to give you mechanically similar parts to test before moving to metal. Printing can also be used to produce plastic parts for sale if the cost of making injection molds is too high. The more functional the prints need to be, the more attention needs to be given to the model and slicing settings to ensure the desired properties.
 +
 +I can print in PLA, PETG, ABS, Nylon and glass fiber or carbon fiber filled variations of these plastics. It is important to keep in mind that the fiber fill does not add to the ultimate isotropic strength of the print, but does make the prints stiffer. This makes carbon or glass fill good for parts that need high rigidity. The reason prints do not become stronger is that when the fibers are extruded through the nozzle they tend to align in the direction of flow and do not penetrate into the previously layer. This means that the layer bonding is not improved by fill materials and the weak point in FDM printing remains. Some strength advantage can be gained if the layer orientation is carefully selected in printing due to this anisotropic behavior. 
 +
 +I also have printers with a heated chamber for printing ABS and Nylon parts without warping. Heated chambers also increase the bond strength between layers, yielding stronger parts.
 +
 +==== SLA ====
 +
 +[[kb:theory:mfg:3d_printing:sla|SLA printing]] creates high resolution resin prints that are great for high detail models. Resin parts are usually more brittle and weaker than thermo-plastic parts. A wide variety of resins are available based on the needs of the project. 
 +
 +SLA printing is excellent for display parts, visual models, and molds or mold plugs. SLA printing can even produce clear parts which is something nearly impossible with FDM.
