Titanium Powder Orders Jump Sixfold: What Tekna's CAD $3M Defense Deal Says About Metal AM Going Serial
One anonymous U.S. defense contract manufacturer just ordered more than CAD $3 million of Ti-6Al-4V powder from Tekna for 2026 — six times its 2025 total — and consumable volume like that is the clearest public signal yet that metal additive manufacturing has moved from prototyping into serial production.

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.

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.

Ireland's First Cement-Free 3D-Printed Wall Is Made From Bauxite Waste — And Cuts Embodied Carbon ~70%
Trinity College Dublin and Harcourt Technologies 3D printed Ireland's first Portland-cement-free geopolymer — a red-brown binder built largely from bauxite refining residue that preliminary figures peg at roughly 70% less embodied carbon than ordinary concrete.

Waterloo's 3D-Printed Contact Lenses Come Off the Printer in 20 Minutes — Custom-Fit to Your Cornea
University of Waterloo chemists paired a purpose-built hydrophilic silicone resin with vat photopolymerization and a non-contact coating step that erases layer lines from the optical surface — producing patient-specific rigid contact lenses in about 20 minutes. Biocompatibility testing is done; in vivo studies are only in preparation.

Johns Hopkins Researchers Crack the Thermal Puzzle Behind Stable Aluminum Metal Extrusion
A JHU team led by Jochen Mueller has mapped the two thermal failure modes that plague aluminum metal extrusion printing and fixed both by varying bed temperature layer-by-layer instead of fighting the nozzle.
