Evergreen how-tos and buyer's guides, written in plain English with the trade-offs that actually matter.
A V-0 rating is always tied to a wall thickness — here's what UL 94, FAR 25.853 and ASTM E662 actually certify, which flame-retardant filaments, resins and powders you can buy, and why printing certified material does not give you a certified part.
Read the story →Rail manufacturers are trading calipers and go/no-go gauges for metrology-grade 3D scanning that maps full parts against CAD to 0.004mm — the same deviation-mapping workflow makers use for reverse engineering and print verification.
Hackaday's July 19 roundup of seven magnet-installation methods lands on an uncomfortable truth: the friction-fit pocket most makers default to loosens over time thanks to thermal creep in the plastic. Here are the alternatives, plus the slot math and pause workflow that make them work.
All3DP's refreshed July 16, 2026 guide maps the routes back to printing after hardware fails — manufacturer support, warranties, returns, paid repair and authorized resellers — and pairs naturally with iFixit's teardowns for the DIY option.
Direct Ink Writing extrudes viscous pastes at room temperature, printing silicone, ceramics, metals, graphene and living tissue that FDM can't touch — a guide to how DIW works and why makers should care.
A maker's cut-and-fold Coroplast top enclosure for the Snapmaker U1 needs no printed parts or hardware — and it lands as Snapmaker sells an official $149 Top Cover, making it the perfect excuse to unpack what an enclosure's thermal, filtration, and dust-blocking jobs are actually worth to you.
Why flow rate governs dimensional accuracy, layer bonding, and surface finish, how Orca Slicer's wizard differs from Bambu Studio's own calibration flow, and how to organize per-filament flow profiles across a library and multiple printers.
Newcastle University engineers used an Artec 3D Spider scanner and PLA printing to resurrect a 1,700-year-old Roman board game from Vindolanda, now played daily by museum visitors.
Maker Ivan Miranda built a nearly all-3D-printed unibody electric motorbike in about ten working days, small enough to disassemble into a checked suitcase for Maker Faire Prague.
Utah engineers built a holographic 3D printer that solidifies a whole microstructure from one 20-second laser exposure instead of hours of layer-by-layer scanning — for now, only at micrometer scale.
Massivit's new Barcelona Service Center 3D prints on-demand molds, mandrels and jigs for aerospace and defense composite manufacturers, aiming to compress tooling lead times from months to days.
ASTM and the UK MOD's Project TAMPA published a free, tech-agnostic guide that sorts 3D-printed defense parts into four criticality classes and two certification paths, aiming to stop programs from reinventing AM qualification from scratch.
Free daily briefing — printer releases, materials, slicer updates, and the business of printing.
