Pratt & Whitney Lines Up Two Additive Partners to 3D Print Full-Scale F135 Engine Structures
At Farnborough 2026, Pratt & Whitney signed two additive deals for the F-35's F135 engine — GKN printing a full-scale engine case with laser wire DED in Norway, and Safran Aero Boosters plus BMT Aerospace tackling supply-constrained titanium parts in Belgium.

Every 3D Printer Has a 'Personality': New AI Profiles Machine-to-Machine Variation
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.

Ceramic 3D Printing's Quiet Boom: Lithoz Posts 40% Materials Growth as Print Farms, Implants, and Turbine Cores Scale
Lithoz reports a 40% jump in ceramic-materials revenue for H1 2026 and raises its full-year outlook, driven by print farms, resorbable implants, and Safran's adoption of LCM silica cores for single-crystal turbine blades.

Meshy's $400M Series B Makes It the Best-Funded Company in Generative 3D — Here's What It Means for Makers
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.

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.

India's Skyroot Reaches Orbit on 3D-Printed Engines: Inside the Restartable Raman-1
Skyroot's Vikram-1 became the first privately developed Indian rocket to reach orbit, riding a fourth stage powered by a cluster of 3D-printed, vacuum-restartable Raman-1 engines that cut build time from months to days.

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.

A Patent for a Pump: nScrypt's Research Arm Locks Down Dispensing Materials Thicker Than a Million Centipoise
Sciperio, nScrypt's research division, has been granted US Patent 12,654,396 B2 for a servo-controlled progressive cavity pump that dispenses materials above 1,000,000 centipoise — the IP foundation under the QuantiHelix platform and nScrypt's DoD point-of-need business.

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.

The Army Corps Is Printing Oyster Reefs Out of Dredged Mud in Mobile Bay
USACE deployed six 3D-printed reef domes off Coden, Alabama — printed from sediment dredged out of a disposal facility, with a built-in experiment pitting pure-sediment domes against sediment-plus-shell.
