Multicolor 5-Axis 3D Printing
https://hackaday.com/2026/03/29/multicolor-5-axis-3d-printing/

Usually, when we see non-planar 3D printers, they’re rather rudimentary prototypes, intended more as development frames than as workhorse machines. [multipoleguy]’s Archer five-axis printer, on the other hand, breaks this …read more (https://hackaday.com/2026/03/29/multicolor-5-axis-3d-printing/)

Self-healing CMOS Imager to Withstand Jupiter’s Radiation Belt
https://hackaday.com/2026/03/29/self-healing-cmos-imager-to-withstand-jupiters-radiation-belt/

Ionizing radiation damage from electrons, protons and gamma rays will over time damage a CMOS circuit, through e.g. degrading the oxide layer and damaging the lattice structure. For a space-based …read more (https://hackaday.com/2026/03/29/self-healing-cmos-imager-to-withstand-jupiters-radiation-belt/)
