Irish company Mcor's unique paper-based 3D printers make some very compelling arguments. For starters, instead of expensive plastics, they build objects out of cut-and-glued sheets of standard 80 GSM ...

There are only a few truly ancient engineered materials, and among the oldest is paper. Traditionally, paper is flat and can be bent into shapes. However, paper can be molded into for example packing ...

• 3D paper snowflakes are surprisingly easy to make. • Just accordion-fold the paper first before cutting a pattern. • Then carefully unfold and tape the edges together. Nearly everyone has made paper ...

Scientists used a 3D-printing approach to pattern hydrophobic barriers inside hydrophilic filter paper. These barriers, designed in different geometries, guide liquids along precise paths and shape ...
