Collaborate Disseminate
When [Michael] over at the Teaching Tech YouTube channel bought a hobby injection molding machine a long time ago, one of the plans he had with it was to use …read more Continue reading Repairing a Home Injection Molding Machine
ARCTOS is a 6-DOF robot arm based upon 3D printed mechanics running a modified version of GRBL firmware. Let’s get this straight now, the firmware is open source, but the …read more Continue reading Arctos Robotics: Build A Robot Arm Out Of 3D Printer Spares?
A 4D printed object is like a 3D printed object, but it changes shape or self-assembles when its environment changes. [Teaching Tech] has been reading about this technology and decided …read more Continue reading DIY Self-Assembling 4D Printing
3D printers are good for a lot of things, but making parts for power transmission doesn’t seem to be one of them. Oh sure, some light-duty gears and timing belt …read more Continue reading 3D Printed Strain-Wave Gearbox Turns Up the Torque
It’s that time of year again — the 2022 Hackaday Prize has officially launched, and we’re excited to see what it turns out. This year’s theme is “Sustainability, Resilience, and …read more Continue reading Hackaday Links: April 3, 2022
We’ve seen a lot of homebrew filament extruders, but [Stefan] at CNC Kitchen shows off a commercial desktop filament extruder in his latest video, which you can see below. The …read more Continue reading Machine Extrudes Filament
Once upon a time, 3D printing was about churning out tiny Yodas and Pikachus, but these days, useful things are regularly 3D printed too. A great example is this centrifugal …read more Continue reading 3D Printing A Centrifugal Water Pump
Just how tight are the manufacturing tolerances of modern FDM printer filament. Inquiring minds want to know, and when such minds are attached to handy fellows like [Thomas Sanladerer], you end up with something like this home-brew filament measurement rig …read more

When the tool you need doesn’t exist, you have to make it yourself. Come to think of it, even if the tool exists, it’s often way more fun to make it yourself. The former situation, though, is one that [Sean Hodgins] found himself in with regard to threaded inserts. Rather …read more

[Stefan] is always trying to make stronger 3D prints. Annealing can strengthen prints, but often at the expense of the part’s exact dimensions. His latest approach is to embed the prints in plaster and then anneal in an attempt to fuse the plastic together without changing its shape or size. …read more
