Slicers, firmware, and the open-source toolchain — release notes translated into settings you can actually use.
OrcaSlicer's nightlies now carry a capability-based Python plugin architecture with an embedded `orca` module, a CPython audit hook and a new per-plugin storage API in draft PR #14923 — and the official docs call the security layer "groundwork, not a hardened sandbox."
Read the story →A GitHub repo has reconstructed parametric CAD for Prusa's INDX toolchanger from Prusa's own printable mesh and published it as CC BY-SA 4.0 — a share-alike claim that runs straight into the Open Community License, which says any distributed derivative stays under OCL.
IMDEA Materials and Berkeley Lab built an algorithm that profiles the operational "personality" of nominally identical 3D printers, then decides whether to optimize them jointly or individually — cutting part-weight errors and speeding convergence across three theoretically identical machines.
Meshy closed a $400M Series B on July 20, 2026 — which it calls the largest round ever in 3D generative AI — behind text- and photo-to-3D tools that export print-ready STL, OBJ, GLB and FBX files straight to your slicer.
Stefan of CNC Kitchen has released PrusaPATuner, an experimental AGPL-3.0 tool that auto-calibrates pressure advance on Prusa printers by repurposing the nozzle load cell as a back-pressure sensor — no extra hardware, no test prints, no squinting at a calibration tower.
Bambu Studio's new public beta can auto-break any target color into an optimal filament mix, sharpens CMYW/RYBW color prediction, and adds official support for E3D's High Flow nozzles.
A community project cross-compiles busybox with the Zig toolchain to add missing Linux tools like less and more to a Z-Mod-modified Flashforge AD5X, working around a Zig floating-point bug with manual ELF patching.
Prusa's 6.6.2 firmware for CORE One/CORE One+ INDX fixes nozzle-cleaner offset drift and tool-pickup ejection, auto-migrates EEPROM offsets, and adds safety options for lost-tool recovery and Dock Calibration.
Italian marketplace MarineLab3D swaps static STL boat-part libraries for JSCAD-based parametric models that users dial to their own dimensions, with a watertight check before download and revenue share for outside designers.
CRP Group's new CRP UniqTrust system links physical Windform parts to a protected digital record via non-clonable NFC packaging, letting buyers verify authenticity ahead of the EU's Digital Product Passport mandate.
Bambu Studio's auto supports are good — but painting enforcers and blockers, manual-only support modes, and per-object overrides are better. A complete walkthrough of the painting tools, blocker objects, tree vs normal styles, and the Z-distance and interface settings that decide whether supports pop off cleanly.
Marlin runs entirely on your printer's own board; Klipper splits the job with a host computer. Both now do input shaping and pressure control. Here is how the two actually compare — and who ships which one stock.
Free daily briefing — printer releases, materials, slicer updates, and the business of printing.
