The Hidden Cost of Speed in 3D Printing: How Extrusion Rate Affects Material Properties
Pushing your 3D printer faster doesn’t just save time, it fundamentally changes the material. Our latest work reveals that higher extrusion rates reduce toughness by up to 85%, increase crystallinity fourfold, and degrade surface quality. Here’s what’s really happening inside the nozzle.
Anamorphic Speckle Patterns: Fixing DIC for Large Structures
Measuring large aircraft structures with Digital Image Correlation from tilted camera angles creates perspective distortions that degrade measurement quality. New research shows how anamorphic transformation of speckle patterns can pre-compensate for these effects, improving measurement precision.
Running Hermes Cron with Minimal LLM Usage
A practical pattern for running frequent cron-like tasks with Hermes Agent while minimizing LLM token usage on local hardware. Standard Linux cron handles polling, and Hermes is injected only when there is actual work to report.
VELUM: Ultra-Lightweight Composite Membranes for Minimal-Leakage Aerial Vehicles
The VELUM membrane architecture achieves competitive helium barrier performance at lower areal mass than commercial aerostat envelopes. By decoupling gas barrier and structural functions, it creates new design space for longer missions and larger payloads in lighter-than-air vehicles.

An Electromagnetic Tether for Satellite Deorbitation: Deployable Composites for Space Debris Mitigation
Space debris is a growing threat to orbital operations. This work presents a deployable composite mechanism for an electrodynamic tether — a passive, propellant-free deorbitation system that uses Earth’s magnetic field to generate continuous braking force and enable end-of-life deorbitation.
Flexible Dry EEG Electrodes from SEBS Composites: Comfortable Brain Monitoring for Active Users
Conventional EEG electrodes are impractical for long-duration wearable use. This research develops flexible dry electrodes from conductive SEBS composites — soft enough to conform to the scalp without gel or pressure, and manufacturable in a single 3D-printed step for brain-computer interface applications.
Printing on the Moon: LDPE–Lunar Regolith Composites for Space Manufacturing
Every kilogram shipped to the Moon is expensive. This work investigates LDPE–lunar regolith composites as a printable feedstock for in-situ additive manufacturing, establishing feasibility and design guidelines for a first-generation lunar 3D printing system.
From Scrap to Print: Upcycling Aerospace CF/PEKK Prepreg Waste for 3D Printing
Aerospace manufacturing generates expensive CF/PEKK and CF/PEEK scrap that is typically discarded. We demonstrate a viable upcycling route: converting prepreg offcuts into printable Fused Granule Fabrication feedstock, with mechanical properties competitive for non-primary structure applications.
Unveiling the Strength of Ultra-Lightweight 3D Printed Micro-Lattices
Ultra-lightweight polymeric micro-lattices offer extraordinary stiffness-to-mass ratios for aerospace. This research maps how photosensitive 3D printing technologies and lattice geometry jointly determine mechanical performance, opening new paths for tailored structural design beyond raw material properties.
Understanding the Ageing of Thermoplastic Composites for Aerospace Applications
How do carbon fibre-reinforced thermoplastic composites degrade under combined UV radiation and moisture? We characterize distinct ageing mechanisms in CF/PPS, CF/PEI, and CF/PEEK — cross-linking vs. chain scission — with direct implications for aerospace component durability and maintenance.
AI-Assisted Literature Reviews: A Practical Video Workflow
A practical video workflow for conducting efficient literature reviews with AI-driven tools. Learn how to quickly grasp the state of the art in a new field using search, Connected Papers, NotebookLM, Gemini, and Zotero.
Understanding 3D Print Strength: Notches vs. Bonding
Why aren’t 3D printed parts as strong as we’d expect? New research identifies two key culprits — incomplete interface bonding and stress-concentrating extrudate notches — and shows how separating these effects changes our understanding of FFF/FGF mechanical performance.
