Fully customized robots

i.materialise, a custom 3D printing fabrication house are looking for talented robotics enthusiasts with the skills to design custom robotics parts such as functional frames, decorative shells, as well as unique parts required by robots to look and perform their best. The best part? They are offering free 3D printing of parts to the people they select with the most interesting or useful ideas. Make sure you check out their blog for details on what they are looking for and how to enter, as well as checking out some of the other cool things they do, such as a fully customizable 3D printed frisbee. Let us know what you design, we would love to show it off!

BAMF2010: DIY electroluminescent displays

In this video from Maker Faire, [Jon Beck] of CLUE — the Columbia Laboratory for Unconventional Electronics — demonstrates the unexpected ease of creating custom electroluminescent (EL) displays using materials from DuPont and common t-shirt screen printing tools. Eagle-eyed reader [ithon] recognized the Hack a Day logo among the custom shapes, which escaped our notice at the time. Sorry, Jon! Very cool project, even if the setup is a bit steep. You’ll find links to materials at the project site.

If the interviewer seems especially sharp, that’s because it’s none other than [Jeri “Circuit Girl” Ellsworth], who makes transistors from scratch and designed the C64 DTV. We’re not worthy!

Printing a RepRap


The RepRap project has been working on bringing 3D printing to the masses by creating a extrusion printer that can also make the majority of its own parts. For the most part, these print ABS or HDPE plastics which are strong and recyclable. In order to create these replicating printers, similar machines called RepStraps are built out of either laser-cut parts or machined elements. They are functionally equivalent to RepRap printers, but are not made of printed parts. [nophead] documented his RepStrap, HydraRaptor, that is based off a milling machine. He had already printed a set of RepRap parts, and he documented printing a second set. The machine worked for about 100 hours over the course of 2 weeks, printing about 1.5 kg of parts. He made a few adjustments, such as replacing ABS bearings with HDPE to reduce friction. The parts are for Factor e Farm so they can get started with 3D printing.

Direct to garment printing

Reader [deren lik] pointed out the world of direct to garment printing to us. You can purchase commercial machines that will print directly onto a t-shirt using inkjet technology. Unfortunately, these machines cost ~$10K, so hackers have decided to fill in the gaps. DIYDTG hosts plans for how to build your own DTG printer. Their standard instructions are based around the Epson C88 printer. A custom carrier is constructed and then the printer components are bolted on top. Commercial DTG printers are also based on Epson parts and you can easily purchase the garment inks even if you didn’t pay a premium for your printer.
