Jiffy 3D Aluminum

Featured

HacDC community member Julia Longtin and collaborator, Mason Mooney, have been developing a fascinating method to 3D print aluminum via a lost PLA method. It is remarkable for its use of commonly available consumer products such as microwave ovens, sugar, and hair spray. They have posted it to Hackaday and we are sure you'd agree that it deserves as many up votes as possible! Please spread the word if you agree!

Finished aluminum part, after removing from mold

“Our system uses consumer microwave units to perform burn-out of PLA from molds, and a second microwave to liquify aluminium, to be poured into the mold. 3d printer inspired mechanics will move the aluminium from the microwave, into the target mold under human control across the network, so that there is no risk to the person operating the machine.

“Lost PLA is usually dangerous, and time consuming. with this, we can go from [PLA] printed part to cast aluminium part in 3 hours!”

Project Byzantium ported to the Raspberry Pi!

Project Byzantium logoThe dev team for HacDC’s awesome, incubated Project Byzantium (PB) has ported their “ad-hoc mesh networking for the zombie apocalypse” platform to the Raspberry Pi. As the 1st milestone of their recent ISC grant award, they’ve started a parallel repository for ByzPi, their PB port for ARM, currently for Raspbian:

We opted to use Raspbian because it seems to be the more popular of the two [commonly installed Raspberry Pi Linux distributions]. Also, the packaging process for Debian was better understood than that for Arch Linux by the Project Byzantium team. We’re in a rapid development cycle so we wanted to hit the ground running and accomplish as much as possible in the available time before the first milestone.

Congratulations to The Doctor, Ben the Pyrate, and haxwithaxe!
