Hasta La Gadget!

If you thought mixtapes died with the MP3 era, you’re wrong. Sure, they’ve become niche, and it’s perhaps cloyingly retro to break out your Walkman, but it’s hard to deny the appeal. There are already USB drives and DAPs made to look like an old-school magnetic cassette, but if you want something a little more DIY, MakerBot has a kit that you purchase and assemble your own MP3-playing “tape.” For $25 you get a package with all the essential internals plus plans for your Replicator to print out the snap together casing. If you’re not lucky enough to have a Replicator of your own, you can upload tracks and have the company print one out for you for $40. Hit up the source link to order one now but, before you go, check out the PR and the video after the break.

Is your 3D printer’s standard feature set lacking? Maybe Elefu’s Kickstarter-funded custom controller board can help. Dubbed Ra (think ancient Egyptian god), the project places a focus on expandability and carries a roster of I/O options including camera triggers and fans. The ATMega2560-based system allows for computer-free printing by leveraging an LCD screen, SD card reader and a knob. For inattentive designers, a standalone and programmable MP3 player and a light controller can be used to create alerts when printing completes, and adds extra flair as well. The unit also supports up to three extruders and plug-and-play support for ATX power supplies. Having doubled its $4,000 funding goal nearly three weeks ahead of the campaign’s end, boards are expected to show up on doorsteps this November and can be snagged for as little as $149. Head to the source for the full feature list and reward tiers.

Printing a chocolate heart is easy enough, but how about an actual organ? There are folks working on it, but it turns out those veins of yours aren’t exactly a breeze to replicate. Researchers at the University of Pennsylvania and MIT may have found a semi-sweet solution — dissolving a sugar lattice in a batch of living Jell-O. The research team uses a RepRap 3D printer and a custom extruder head to print a filament network composed of sucrose, glucose and dextran which is later encased in a bio-gel containing living cells. Once the confectionery paths are dissolved, they leave a network of artery-like channels in their void. Tissue living in the gel can then receive oxygen and nutrients through the hollow pipes.

The research has been promising so far, and has increased the number of functional liver cells the team has been able to maintain in artificial tissues. These results suggest the technique could have future research possibilities in developing lab-grown organs. MIT Professor Sangeeta Bhatia, who helped conduct the effort, hopes to push the group’s work further. “More work will be needed to learn how to directly connect these types of vascular networks to natural blood vessels while at the same time investigating fundamental interactions between the liver cells and the patterned vasculature. It’s an exciting future ahead.” Scientists at other labs could also get their mitts on the sweet templates since they’re stable enough to endure shipping. Head past the break for a video of the innard infrastructure.
