PLA in FDM 3D Printing: Studying the Effects of Porosity & Crystallinity

In the recently published, ‘Effect of Porosity and Crystallinity on 3D Printed PLA Properties,’ international researchers look further into FDM (FFF) 3D printing with PLA, examining physical changes during fabrication….

Singapore: Effects of Porosity on Mechanical Properties in FDM 3D Printing

Authors Xue Wang, Liping Zhao, Jerry Ying His Fuh, and Heow Pueh Lee lead a complex discussion about porosity in 3D printing in their recently published article, ‘Effect of Porosity…

Researchers Tailor Graphene Content in Bespoke Filament for 3D Printed Porous Anodes in Batteries

Long-lasting, rechargeable lithium-ion (Li-ion) batteries have a high energy density and low self-discharge, and are finding their way into aerospace and military applications, among others. As the demand for energy…

Do Higher Print Temperatures Lead to Better FDM PLA 3D Printed Parts?

Many factors impact the quality of 3D printed parts, and as the technology is used more and more for production of final parts rather than just prototyping, it is necessary…

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…

Is Higher Extrusion Speed Key to Improving FDM Part Quality?

FDM 3D printing technology is being used for more and more high-performance industrial and scientific applications as materials evolve, and filaments made from PEEK, PEKK and other high-temperature materials become…

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…

Research Team Uses Synchrotron Beamline to See Inside Laser 3D Printing Process

While we know that 3D printing gives us the ability to create complex shapes and geometries that would be impossible to achieve with conventional forms of manufacturing, less frequently discussed…

3D Printing at Dutch Design Week: The Klokgebouw

During Dutch Design Week, the city of Eindhoven becomes a hub for design. Over a quarter of a million people attend and there are over 100 venues and 2500 participating…
