Students' 3D-Printed PETG Jet Is Gunning for the RC Speed Record
The Mach Initiative's KingChaser, a 9 kg jet built mostly from PETG with a PPS-CF engine bay and a 300 N turbine, is aiming at the 465 mph RC jet record. Annealed PET-CF warped on the way there, and the jet has not flown yet.

Waterloo Researchers 3D Print a PLA Filter That Pulls 90% of Microplastics From Water
University of Waterloo researchers turned stacked FDM-printed PLA discs into a microplastics trap by etching pores into them and adding a sticky acrylic coat, reaching 90% removal at 20 layers. It is still a proof of concept, and it works less well on the smallest particles.

Why Water Content Decides How Printable Cement Flows: Multiscale Study Explains Shear Thinning
A Journal of Applied Physics study feeds atomistic simulations of cement and water into a particle model, showing that more water lowers paste viscosity and proposing a microscopic cause for the shear thinning that makes construction printing work.

Virginia Tech Lab 3D Prints Circuits That Heal Themselves With Liquid Metal
VT MADE Lab's gallium-indium-in-PDMS composite stays insulating until punctured, then turns conductive and stitches itself back together — a printable material makers could one day pour, mold, or 3D print into self-repairing flex circuits.
