Hackaday Prize Entry: RepRap Helios

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 http://pje.fyi/P5t6GW

Laser Cutting a 3D Printer

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 http://pje.fyi/Nf9Dmd
