This open source analyzer comes with an easy-to-use setup and tests each and every parameter of a stepper motor.
If you have a 3D printer and want to analyze the stepper motor signals without the use of a computer and expensive stepper analyzer, then this low-cost hardware design can solve your problem. The open source analyzer comes with an easy-to-use setup and can be easily built to give you the capabilities to test each and every parameter of the stepper motor.
Lios Design, a team formed by MIT students, is well on its way to perfecting molten glass 3D printing.
The vast majority of 3D-printed objects are plastic. Most FFF (Fused-Filament Fabrication) 3D printers use thermoplastic filament and LCD/SLA (Stereolithography) 3D printers use photopolymer resin. Other materials, like ceramic, concrete, and metal, are somewhat common. We’ve even seen organic tissue and various foods being 3D-printed on occasion. But glass is difficult to print, because of the temperatures required and the physical properties of molten glass. That’s why it is impressive that Lios Design, a team formed by MIT students, is well on its way to perfecting molten glass 3D printing.
Software developer 3D Control Systems, the parent company of 3DPrinterOS, has become a corporate sponsor of open source interface OctoPrint to help ease 3D printer integration processes.
Through its 3DPrinterOS platform, the company will help users and companies integrate Octoprint into their 3D printing workflows by means of its new 3D Printer Software Development Kit. By offering integration as a software service, the partners are hoping to save customers time and money on developing their own software to fully integrate OctoPrint with their systems.
We’re all too familiar with the 3D printing post-processing step of removing supports, and lamenting the waste of plastic on yet another dwindling reel of filament. When the material is expensive NinjaFlex or exotic bio-printers, printing support is downright painful. A group at USC has come up with a novel way of significantly reducing the amount of material that’s 3D printed by raising portions of the bed over time, and it makes us wonder why a simpler version isn’t done regularly.
In the USC version, the bed has a bunch of square flat metal pieces, with a metal tube underneath each. The length of the tube determines the eventual height of that square. Before the print is made, the bed is prepared by inserting the appropriate length tubes in the correct squares. Then, during the print, a single motor pushes a platform up, and based on the height of the pin, that portion of the bed raises appropriately, then stops at the right height.
I have designed yet another cycloidal drive! This one is different, though. Unlike most of my projects, it is strictly 3D printed. No CNC required. The cycloidal mechanism is also “inside-out”. The cycloidal discs do not rotate, they only wobble, transmitting rotation to the output. This was also designed to maybe be used in a modular robot arm. It’s also a 25:1 gear reduction.

Although an Arduino can be a great way to provide computing power for a mobile robot, you’ll need a variety of other electronics and mechanical components to get it going. In his write-up, computer science student Niels Post outlines how he constructed a robotic platform that travels via two stepper motors, along with casters to keep it upright. Its round chassis is 3D-printed and runs on three rechargeable 18650 batteries.
When somebody builds a quadcopter with the express purpose of flying it as fast and aggressively as possible, it’s not exactly a surprise when they eventually run it into an immovable object hard enough to break something. In fact, it’s more like a rite of passage. Which is why many serious fliers will have a 3D printer at home to rapidly run off replacement parts.
Avid first person view (FPV) flier [David Cledon] has taken this concept to its ultimate extreme by designing a 3D printable quadcopter that’s little more than an 18650 cell with some motors attached. Since the two-piece frame can be produced on a standard desktop 3D printer in a little over two hours with less than $1 USD of filament, crashes promise to be far less stressful. Spend a few hours during the week printing out frames, and you’ll have plenty to destroy for the weekend.
