Jiffy 3D Aluminum

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!”

Open Hack Night: Wednesday, Aug 25

Ash’s Electronics class wound down last Wednesday, but that’s no reason to stop soldering!

Elliot will be trying to make a bridged, push-pull amplifier out of a couple of LM386s. (There’ll be plenty for experimenting, if you feel like helping out or making one for yourself.)

Otherwise, come on by and just get yer hack on.
