Finite Element Modeling Used to Study How Defects Can Effect Porosity in 3D Printed Lattice Structures

For applications that require lightweight structures able to maintain stiffness and strength, 3D printed lattice structure are often used. The complex forms are simple to 3D print, and their mechanical…

Monitoring the Laser Powder Bed Fusion 3D Printing Process with Spectroscopy to Detect Defects

Laser powder bed fusion 3D printing, one of the most well-established processes for producing metal parts, uses a powder bed of material to build a part layer by layer. The…

Researchers Develop Machine Learning Method to Monitor 3D Printing Process for Defects

All sorts of issues can occur when a 3D printed part has a defect, and researchers around the world continue trying to find new ways to detect these defects before…

Gold Nanoparticles Illuminate Defects in 3D Printed Objects

Defects in 3D printed parts can cause all sorts of problems, but they’re often so small that they can’t be easily detected, if at all. Vanderbilt University researchers are the…

Reducing High Porosity and Improving Sealing Properties in Extrusion-Based 3D Printing

While there’s been a lot of ongoing research into what causes structural defects (porosity) and other flaws in metal 3D printed parts, let’s not forget that 3D printed objects made with…

Brilliant Flash of Light Lets Scientists Study Structure of 3D Printing Material at Atomic Level to Reduce Defects

Additive manufacturing processes, while amazing and valuable, are not without their flaws, and lots of research has been conducted into how and why defects in 3D printing that can cause…

Researchers Use Sensors, Microphones, and Nanoparticles to Develop Three Methods to Combat 3D Printer Cyberattacks

When it comes to computers and other technology, hacking, by definition, can mean either to modify in a clever, skillful way, or to get around security with malicious intent. So…

Cybersecurity Needs Amping Up in 3D Printing—Vulnerability Shown During Printing Orientation

If you get in at the beginning of a new technology or major trend, often there is time to enjoy that wonderful euphoric window of time while it’s still slightly…
