Big Data Management in Additive Manufacturing

Additive Manufacturing of polymers is transitioning from rapid prototyping to a true industrial production technique. While it brings valuable opportunities to the industry it also comes with a series of challenges for the engineers: the reliability of the mechanical properties of the final part still has some uncertainty and is not fully supported by standard …

How to Resolve Warpage and Residual Stresses in Additive Manufacturing

The 2010s featured many new technologies that were once labeled ‘futuristic’ technologies, including drones, self-driving vehicles and printing physical parts. Additive manufacturing or 3D printing really took off this decade, but is not a straightforward and simple process. To print reliable parts, an engineer must overcome one of the biggest challenges in additive manufacturing. Warpage …

How to Simulate Autonomous Vehicle Technology

Autonomous vehicle technology and advanced driver-assistance systems (ADAS) are advancing every year, and its reliability is dependent on both sophisticated engineering and testing. Much has been written about real word testing of autonomous vehicles, but little has been written regarding the simulation portion. The goal of this post is to briefly discuss virtual simulation technology …

Effect of Defects on Part Made with AFP Using Digimat

Automatic Fiber Placement (AFP) is a fast and efficient deposition process of carbon prepreg for large component application. To accommodate the composite strips onto a double curved surface, the tows can be cut then restarted and slightly misoriented, yielding to the apparition of gaps between the tows. These two defects, i.e. the gaps and misalignment …
