3DWithUs – 3D Printing, Scanning, Design Guides & Forums

The Revopoint POP 4 is a compact 3D scanner that combines blue laser and infrared scanning modes for different object types and workflows. In this hands-on review, I tested it with several real-world objects, including foot scans, a color scan, a scan-to-print shoe-stretcher experiment, and a tiny broken RC boat propeller that pushed the scanner close to its practical limits....

3D printed shoes are no longer just experimental prototypes. They are becoming wearable products that people can actually experience in everyday conditions. From lattice midsoles used by global sports brands to fully 3D printed footwear produced without traditional tooling, additive manufacturing is steadily reshaping how shoes are designed, manufactured, and customized.

Multi-color 3D printing has become one of the most visible trends in desktop and prosumer FDM 3D printing. From decorative models to functional parts with different materials, the appeal is clear. The challenge, however, is that many current systems still rely on filament switching through a single extrusion path, which often leads to purging, wasted material, and longer prin...
