I t can be frustrating to prepare your 3D model, start 3D printing, only to realize that the first few layers of the print are sagging or just plain messy. Sagging of the first layers of the print ...

Rice scientists are making 3D laser-induced graphene (LIG) foam through an automated process that begins by turning the top layer of a polyimide (PI) sheet into graphene (top), stacking another layer ...

One type of 3D printing, stereolithography, creates objects by exposing sequential layers of light-sensitive resins to patterns of light, which cure the polymer into the desired shape.

Scientists have developed a new 3D printing method that mimics the way animals move by blending soft and rigid materials—just ...

It is a fact of life that 3D printed parts from an FDM (fused deposition modeling) printer have weaknesses where the layers join. Some of this is due to voids and imperfect layer bonding, but you c… ...

Three-dimensional (3D) nanostructures assembled with one- or few-layered ultrathin two-dimensional (2D) crystals have triggered great interest in energy and environmental applications. Here, we ...

The layup process for 3D parts combines robot-assisted spray-up of liquid PUR with hand-placed layers of nonwoven mats and reticulated foam core. The cured surface layer is placed in the lower mold ...

Although we've seen bicycle helmets with shells made of everything from wood to paper, they've pretty much all featured foam cores. The 3D-printed kupol is a little different, as it utilizes a ...

Desktop Metal Inc plans to unveil a type of foam that the U.S.-based industrial 3D printer maker claims could significantly change the way athletic shoes, automotive seats and other products are ...

Expandable foam for 3D printing large objects (video) American Chemical Society. Journal ACS Applied Materials & Interfaces DOI 10.1021/acsami.0c02683 ...
