Evergreen how-tos and buyer's guides, written in plain English with the trade-offs that actually matter.
My Tech Fun's head-to-head found desktop PC-ABS from a Prusa Core One L and Bambu Lab H2D nearly matched a six-figure Stratasys Fortus 450mc on strength and beat it on looks, with dimensional accuracy the industrial machine's only clear win.
Read the story →A side-by-side Izod impact test on matched Fiberlogy PETG and PCTG spools shows PCTG bending instead of snapping — but that toughness comes with ASA-like print temperatures.
A Hackaday analysis argues consumer FDM has stalled mechanically since 2020 even as color and tool-changing trickle down to budget machines — so is it time to look past the nozzle?
Building on his laser layer-adhesion work, YouTuber 'I Changed a Thing' bolted two diode lasers to an FDM printer's X-axis to remelt top surfaces near vapor-smoothed quality with no chemicals, though wall smoothing remains a much harder problem.
A syringe-pump extruder and a mineral-oil-and-fumed-silica support gel let a maker embedded-print a two-part-epoxy Benchy, hinting at FDM printing with materials no ordinary hot end can touch.
Somerset's library 3D printing service scanned a 1,700-year-old gold Roman signet ring with a Creality Sermoon P1 and printed a handling replica so museum visitors can hold what the fragile original can't survive touching.
Makers Sam Barker and Tom 3D-printed a working, seesaw-powered railway pump car small enough to pack in airline luggage, and gave the files away free on Printables.
A laser-assisted pre-melt technique spotted by Hackaday pushed Z-axis breaking strain to 94% of X-axis strength on ABS and 77.9% on PLA, directly attacking FDM's oldest structural weakness: layer adhesion.
Hackaday's Maya Posch pit an Elegoo Neptune 4 against Uniformation's 16K GK3 Ultra resin printer and came away convinced SLA wins on fine detail — but warns FDM users printing ABS/ASA need real respiratory protection.
Hobbyist Irtaza2009 open-sourced PiShot, a 3D-printed compact-camera-style case built around a Pi Zero 2 W, Camera Module 3, and a rear ST7789 screen, with full design files and Python code posted to GitHub.
Roetz-End creator Jan is replacing the solid core of printed tubing with a compressed-air stream, chasing hollow parts that are up to 90% air — but pressure swings and leaks are still winning.
A new guide untangles which filaments, resins and powders can legitimately claim food contact status under FDA and EU rules — and why the part, not the material, is what actually gets certified.
Free daily briefing — printer releases, materials, slicer updates, and the business of printing.
