Burning 3D Prints: Which Filaments Catch Fire and Why

A Maker’s Muse fire-test examines how different 3D printing filaments burn: PLA ignites readily and burns with a dirty flame, HTPLA resists ignition, PETG is hard to ignite, ABS/ASA burn with a sooty yellow flame, and TPU is the least flammable (though foam TPU can burn more aggressively). The results suggest choosing PETG and TPU to minimize fire hazards, with burn behavior largely influenced by filament additives and formulation.

Massive Cosmic Filament Reveals Synchronized Galaxy Spins, Posing New Spin-Formation Questions

Astronomers identified a colossal cosmic filament about 50 million light-years long containing roughly 300 galaxies, many of which appear to rotate in sync with the filament at about 110 km/s. This coordinated motion challenges standard ideas of how galaxies acquire spin (tidal torque) and suggests large-scale structure may influence spins more than expected. It’s an early, single striking case that requires more surveys and simulations to determine whether this synchrony is common and how theory might adapt.

Hidden Filaments in Milky Way Core Trace Ancient Black Hole Outflow

Astronomers using the MeerKAT radio telescope found a new population of horizontal, 5–10 light-year filaments near the Galactic Center that point toward Sagittarius A*. Their thermal emissions and alignment along the galactic plane differ from previously known vertical filaments, suggesting a past energetic outflow from the Milky Way’s central black hole and offering clues about its accretion disk orientation and history.

Infrared fingerprints tie some 3D-printed guns to their filament

A Curtin University study published in Forensic Chemistry shows that infrared spectroscopy of 3D-printing filaments can distinguish many filament types and link seized ghost guns to their source, challenging the notion that ghost guns are truly untraceable; however, some filaments remain indistinguishable, and researchers plan to add more analytical techniques to strengthen traceability.

Mysterious Structures and Filaments Discovered in the Heart of the Milky Way

Astrophysicists have discovered one-dimensional filaments between 5-10 light-years in length in the Milky Way, thought to be outflows from Sagittarius A, a supermassive black hole at the center of the galaxy. These filaments are exceptionally long strings of electrons interacting with a magnetic field and only appear on one side of Sag A, pointing radially toward the black hole. The discovery was made possible by enhanced radio astronomy technology, specifically the South African Radio Astronomy Observatory’s MeerKAT telescope. The filaments could help scientists learn more about the way Sag A spins and its orientation relative to the rest of the Milky Way.

Mysterious Galactic Filaments and Threads Discovered in Milky Way's Core

New filaments have been discovered near the Milky Way's supermassive black hole, Sagittarius A*. These filaments are shorter and lie horizontally, pointing directly to Sagittarius A*. They are related to the activity of Sagittarius A*, but it is unclear if the two types of filaments are related. The vertical filaments are magnetic accelerating particles close to the speed of light, while the horizontal ones appear to emit heat, accelerating thermal material in a molecular cloud. The newly discovered filaments are estimated to be about 6 million years old and may have originated from an outflow from an activity that happened a few million years ago.

Mysterious structures and filaments discovered in the Milky Way by scientists.

An international team of astrophysicists has discovered hundreds of mysterious structures in the center of the Milky Way galaxy. These one-dimensional cosmic threads are hundreds of horizontal or radial filaments, slender, elongated bodies of luminous gas that potentially originated a few million years ago when outflow from Sagittarius A*, the Milky Way’s central supermassive black hole, interacted with surrounding materials. The researchers found the structures by analyzing images produced by the South African Radio Astronomy Observatory’s MeerKAT telescope.

Mysterious Structures and Filaments Discovered in the Heart of the Milky Way

An international team of astrophysicists has discovered a new population of threads at the center of the Milky Way, which differ from their vertical counterparts, being significantly shorter and arranged horizontally or radially, resembling spokes radiating outward from the black hole, like Morse code's dots and dashes. While the vertical filaments sweep across the galaxy, towering as high as 150 light-years, the horizontal filaments punctuate only one side of Sagittarius A* and exhibit a pattern akin to Morse code.

Mysterious Filaments and Structures Discovered in Milky Way's Center

Astronomers have discovered hundreds of mysterious filaments pointing towards the Milky Way's supermassive black hole, Sagittarius A*. The filaments, which are less than 10 light years in length, are estimated to be about six million years old and appear to be tied to activities in the galactic center. The discovery was made possible by the South African Radio Astronomy Observatory's MeerKAT telescope. The filaments could provide insights into the black hole's spin and accretion disk orientation.

Mysterious ancient structures and filaments discovered in Milky Way's center.

Astronomers have discovered hundreds of previously unknown "filaments" at the center of the Milky Way, each measuring between 5 and 10 light-years in length and visible only in radio wavelengths. These structures appear to point directly at the central supermassive black hole, Sagittarius A*, suggesting that they may be the unhealed scars of an ancient, high-energy black hole outburst that tore through the surrounding clouds of gas. The filaments were likely created by bursts of high-energy particles that are invisible to the naked eye, and may have been caused by an eruption of energy from the black hole around 6 million years ago.
