Open-source 3D printing breaks the speed barrier with axial lithography

Computed Axial Lithography (CAL) prints entire objects in seconds by projecting rotating 2D images through a spinning resin cylinder—orders of magnitude faster than layer-by-layer FDM or SLA methods. Open-sourcing the technology lets hackers build CAL printers for a fraction of commercial systems' cost, moving the technique from lab curiosity to accessible infrastructure for rapid prototyping and on-demand manufacturing.

Why Noctua's Open Fan Files Won't Democratize PC Hardware

Source: Hackaday

Noctua's decision to release CAD files for their fans is a calculated brand move, not open-source surrender. The company retains IP control while gaining goodwill and user-generated test data. 3D-printed fans can't yet match injection-molded designs in noise performance, durability, or thermal efficiency, so the files function more as a design reference and marketing gesture than a genuine manufacturing alternative. This mirrors how other hardware companies use open specs: controlling the narrative around customization while production economies of scale remain with the original manufacturer.
