These alternating turnaround areas leave pathways or airgaps through the layers, i.e. By default, raster angle controls are set to start at 45В° and alternate by 90В° delta (see above). Next, weвЂ™ll look at rasters, because youвЂ™re likely to have some areas that will require them. Best practice is to run a вЂњgreen flagвЂќ as a control and take note of the estimated time and material before modifying parameters. Note:В Modifying some of these parameters may vary your build time and material usage.

Alternatively, you can apply Contour Width and Link Contours globally if it suits your needs through the Toolpath Setup menu. I also have the Link Contour box checked and gave it a -0.001 air gap. IвЂ™ve used five (5) contours with a 0.020 contour width. In this example, shown in the parameters for a custom group, I have a 0.100 wall thickness. This feature will create continuous toolpaths by eliminating start and stop points between each contour. Select the Link Contours feature and add a slight negative contour-to-contour air gap whenever possible.Within each group, youвЂ™ll be able to control the number of contours and their respective widths. Set up Custom Groups for each thickness and add the layers to the groups.You can select a range of layers that have the same wall thicknesses. Determine your wall thickness by measuring at each layer and then do the math, so wall thickness is equal to the number of contours multiplied by contour width.The existence of rasters within a model increases the risk of leakage, due to the air gaps they create as shown below (top image).ДЇrom the Groups toolbar, you can setup the parameters to reduce air gaps following these steps: Fundamentally, this technique relies on using additional contours and in turn reduces or eliminates rasters from these layers. Once youвЂ™ve determined the optimal orientation, the next step is to add multiple contours to the vertical walls (bottom image). The most important rule is to orient the part so that most surfaces are oriented vertically. This will require your judgment and the application needs. The first step is addressing the orientation of the build on the platform. It wonвЂ™t be as effective at higher pressures/vacuum, or with complex part geometries. This is true as long as the application requirements are to hold a gas or liquid around atmospheric pressures. With Insight, you have the ability to control or even eliminate the porosity concern, especially with simple geometries. In other words, sometimes leaching is helpful. The natural porosity allows the soluble solution to reach the support material as well as drain from those same areas that may be concealed. If not, hereвЂ™s why: the model may have areas that arenвЂ™t self-supporting so the supports need to be removed and dissolved. If youвЂ™re already familiar with FDM, you may be aware of why porosity is often necessary. And guess what? Unlike most post-processing methods, this strategy wonвЂ™t change the part geometry.

So if youвЂ™re the frugal type, you should put your efforts into processing STLвЂ™s upfront with an UltemВ fist to ensure those manual operations arenвЂ™t necessary. Employing StratasysвЂ™ Insight software, included with StratasysвЂ™ Fortus line, is an easy way to solve porosity issues on most geometries conversely, some complex geometries may potentially require labor intensive post-processing. Geometry will greatly impact which technique, or combinations of techniques, are required to seal the part for testing, and then end use.
