When a Go-Kart Shrinks to Suitcase Size, Engineering Gets Very Real
Ivan Miranda’s 3D-printed kart is less a toy-sized stunt than a reminder that portability changes how a machine is built, handled, and rebuilt.
Why Faster Color Printing Still Runs Into the Same Old Bottleneck
A new method aimed at accelerating multi-color 3D printing is interesting not just for speed, but for what it reveals about the stubborn cost of changing materials mid-print.
3D-Printed Stencils Turn a Small PCB Job Into a Smarter Build Choice
A low-cost stencil can simplify solder paste application for surface-mount work, but the real story is the tradeoff between convenience, precision, and what a shop actually needs from its tooling.
Back to the Vat: What a Six-Year Pause Reveals About Resin Printing
A return to resin 3D printing after years away turns into a reminder that the hardest part of the hobby is often not the machine, but the workflow around it.
Seven Magnet Mounts, One Problem That Tests the Print
A simple add-on can become a long-term reliability test when a magnet has to stay put inside a 3D print.
When a Print Bed Won’t Let Go, the Real Lesson Is Process Control
A simple fix for flex filament reveals how much 3D printing depends on repeatable surfaces, disciplined cleanup, and knowing when a shortcut is only a shortcut.
Clay, Motion, and a Harder Kind of Print
A new clay extruder puts printable pottery in reach, while also showing why ceramic 3D printing remains far less common than standard FDM machines.
A Handle, a Pi, and a Bigger Shift in How Personal Computers Get Built
A compact Raspberry Pi portable with a built-in handle is a small maker project with a larger meaning: desktop 3D printers and single-board computers are making custom personal devices easier to assemble.
Volumetric 3D Printing Is Moving Fast - But Adoption Still Has to Earn Its Trust
A new way of making objects in one go sounds futuristic, yet the real test is whether the process can be practical, repeatable, and easy to fit into everyday manufacturing.
When AI Starts Sculpting the World: The Hidden Risk in 3D Generation
Turning prompts, photos, and video into 3D assets looks like a creative leap, but the security story is really about trust, validation, and who controls the workflow.
Inside the 3D-Printed Raman Spectrometer Entering the Frikkin Lasers Challenge
Hackaday’s challenge feature spotlights a printed optical instrument built around Raman scattering, where tiny wavelength shifts can reveal how light interacts with matter.
A Mechanical Display That Saves Power by Staying Still
A 3D-printable split-flap build shows how an old display format can still offer a useful lesson in efficiency, reliability, and the hidden complexity of simple hardware.
When Printed Parts Could Be Unmade: The Chemistry Behind Reusable Resin
A depolymerizable resin concept points toward a future where some 3D printing materials may be reclaimed instead of discarded.
A Bicycle, a Shredder, and a Smarter Way to Handle 3D-Print Waste
Brogan M Pratt and his students turned a simple bike-powered machine into a practical answer for the plastic scraps that accumulate around 3D printing.
OpenCAL Pushes a Strange Kind of 3D Printing Out of the Lab and Into the Real World
A project tied to computed axial lithographic printing is being framed as a step toward wider use, and that shift matters because the more advanced fabrication becomes, the more its digital inputs deserve careful trust.
When a Printer Queue Becomes a Trust Problem
Bambuddy is a new reminder that even a desktop manufacturing workflow can become a question of privacy, control, and where your files travel before a job starts.
A Tiny Glue Joint, and a Better Way to Build Moving Parts
Alex Krush’s glue-in filament hinge is a small 3D-printing idea with a practical aim: add motion without redesigning the whole mechanism.
When a Garden Gadget Gets a Digital Print Job
A 3D-printed hose sprayer is a small maker project, but it neatly shows how everyday tools now pass through digital design, fabrication, and testing before they ever reach the yard.
How a Legendary Robot Becomes a Print Job
Ogrinz Labs is building a replica of Robby the Robot, and the project began the old-fashioned way: by examining an original for high-resolution reference material.
3D Printing Meets Deep Cold in a Gifford-McMahon Build
A Hackaday project puts a classic cryogenic cooling design in the hands of modern fabrication, showing how DIY hardware now blends old-school physics with digital manufacturing.
