Hackaday Prize Entry: RepRap Helios

Posted on by

Did you know that most of the current advances in desktop consumer 3D printing can be traced back to a rather unknown project started in 2005? This little-known RepRap project was dedicated to building Open Source hardware that was self-replicating by design. Before the great mindless consumerization of 3D printing began, the RepRap project was the greatest hope for Open Source hardware, and a sea change in what manufacturing could be.

While the RepRap project still lives on in companies like Lulzbot, Prusa, SeeMeCNC, and others, the vast community dedicated to creating Open Hardware for desktop manufacturing has somehow morphed …read more

Laser Cutting a 3D Printer

Posted on by

The concept of self-replicating 3D printers is a really powerful one. But in practice, there are issues with the availability and quality of the 3D-printed parts. [Noyan] is taking a different approach by boostrapping a 3D printer with laser-cut parts. There are zero 3D-printed parts in this project. [Noyan] is using acrylic for the frame and the connecting mechanisms that go into the machine.

The printer design chosen for the project is the Prusa i3. We have certainly seen custom builds of this popular design before using laser-cut plywood for the frame. Still, these builds use 3D-printed parts for some …read more

The Tiny 3D Printers Of Maker Faire

Posted on by

Building a big 3D printer has its own challenges. The strength of materials does not scale linearly, of course, and long axes have a tendency to wobble. That said, building a bigbot isn’t hard – stepper motors and aluminum extrusion are made for industry, and you can always get a larger beam or a more powerful motor. [James] is going in the opposite direction. He’s building tiny, half-scale printers. They’re small, they’re adorable, and they have design challenges all their own.

At this year’s New York Maker Faire, [James] is showing off his continuing project of building baby 3D printers. …read more

3D Printering: Trinamic TMC2130 Stepper Motor Drivers

Posted on by

Adjust the phase current, crank up the microstepping, and forget about it — that’s what most people want out of a stepper motor driver IC. Although they power most of our CNC machines and 3D printers, as monolithic solutions to “make it spin”, we don’t often pay much attention to them.

In this article, I’ll be looking at the Trinamic TMC2130 stepper motor driver, one that comes with more bells and whistles than you might ever need. On the one hand, this driver can be configured through its SPI interface to suit virtually any application that employs a stepper motor. …read more

Modding The Monoprice MP Mini Printer

Posted on by

Two weeks after my review of the MP Select Mini 3D printer, Monoprice’s own website has said this printer has been out of stock, in stock, and out of stock again several times. This almost unimaginably cheap 3D printer is proving to be exceptionally popular, and is in my opinion, a game-changing machine for the entire world of 3D printing.

With the popularity of this cheap printer that’s more than halfway decent, there are bound to be improvements. Those of us who have any experience with 3D printers aren’t going to be satisfied with a machine with any shortcomings, especially …read more

Build A 3D Printer Workhorse, Not an Amazing Disappointment Machine

Posted on by

3D printers have become incredibly cheap, you can get a fully workable unit for $200 – even without throwing your money down a crowdfunded abyss. Looking at the folks who still buy kits or even build their own 3D printer from scratch, investing far more than those $200 and so many hours of work into a machine you can buy for cheap, the question “Why the heck would you do that?” may justifiably arise.

The answer is simple: DIY 3D printers done right are rugged workhorses. They work every single time, they never break, and even if: they are an …read more

Prusa Shows Us the New i3 MK2 3D Printer and Where the Community is Headed

Posted on by

Josef Prusa’s designs have always been trustworthy. He has a talent for scouring the body of work out there in the RepRap community, finding the most valuable innovations, and then blending them together along with some innovations of his own into something greater than the sum of its parts. So, it’s not hard to say, that once a feature shows up in one of his printers, it is the direction that printers are going. With the latest version of the often imitated Prusa i3 design, we can see what’s next.

The printers from Prusa research are my recommendation for anyone …read more

Ask Hackaday MRRF Edition: 3D Printers Can Catch Fire

Posted on by

[Jay] out of the River City Labs Hackerspace in Peoria, IL cleared out a jam in his printer. It’s an operation most of us who own a 3D printer have performed. He reassembled the nozzle, and in a moment forgot to tighten down the grub nut that holds the heater cartridge in place. He started a print, saw the first layer go down right, and left the house at 8:30 for work. When he came back from work at 10:30 he didn’t see the print he expected, but was instead greeted by acrid smoke and a burnt out printer.

As …read more
