Stratasys 3D Printing: Self-Supporting Angles with FDM

EmailFacebookLinkedInTwitterShare

Self-Supporting Angles with FDM   Looking to save some time when printing with FDM?   Generally, in 3D printing processes when there is some of overhanging feature, support will be required to be underneath. The time it takes to switch between support material and model material can add up to a lot by the time the build is finished. However, when using the FDM process, there is a degree of self-supporting angles that can be utilized to greatly reduce printing […]

Create the Best Design Through Optimization

Finding the best design is important for all engineers.  Whether by minimizing the amount of material or changing the material completely, cost can be saved.  While possible to create multiple simulation studies with minor differences to find the best design, separate studies take extra time, even when run at the same time.  One tool to help accomplish these tasks is Optimization through a design study.  First a  static study must be done.   While this design appears to be good, […]

Mesh Control – A Double Edged Sword

EmailFacebookLinkedInTwitterShare

When running simulations, mesh density is important.  Coarser meshes solve faster but are less accurate; while finer meshes are the opposite, slow but accurate.  While one way to reach the middle ground is to have the density right in the middle, a more accurate way would be to use mesh control.  Stress concentrations most commonly occur along edges, especially sharp edges.  On edges and other areas where accuracy is important, mesh control is a great way to keep that accuracy […]
