Sub-0.005mm and No Tape Measure: How Non-Contact 3D Scanning Is Taking Over Quality Inspection
Rail manufacturers are trading calipers and go/no-go gauges for metrology-grade 3D scanning that maps full parts against CAD to 0.004mm — the same deviation-mapping workflow makers use for reverse engineering and print verification.

Hembased's Palm-Leaf Filament Composts in a Backyard Bin — If You Believe the Claim
Dutch startup Hembased is selling a cold-compostable FDM filament made from fallen palm leaves at 32 euros/kg, claiming 12-month breakdown in a home compost bin — but the category dates to 2013 and the company names no third-party compostability certification.

The Navy Just Cleared a 3D-Printed Copper-Nickel Valve for Submarine Duty — A Material Almost Nobody Prints
VACCO delivered a laser-powder-bed-fusion copper-nickel pressure valve cleared for US Navy submarine installation — and a second, independent supply chain is doing the same thing, which says something about where casting is losing.

CNC Kitchen's PrusaPATuner Turns Your Bed-Leveling Load Cell Into a Pressure Advance Calibrator
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.

Seven Ways to Put Magnets in Your 3D Prints (and Why Friction Fit Alone Will Fail You)
Hackaday's July 19 roundup of seven magnet-installation methods lands on an uncomfortable truth: the friction-fit pocket most makers default to loosens over time thanks to thermal creep in the plastic. Here are the alternatives, plus the slot math and pause workflow that make them work.

Concordia's 'Inverse 4D Printing' Makes Wind-Turbine Blades That Fold Themselves Into Shape
Concordia researchers print carbon/epoxy laminates flat, then let engineered thermal-expansion mismatch curl them into finished vertical-axis turbine blades on cooling — no curved mold, ~80% lighter than aluminum, and faster-spinning in lab tests.
