Possible Fire Hazard: Wanhao Duplicator I3 3D Printer

September 17, 2016 by Moritz Walter 37 Comments

A while ago Wanhao was reaching out to its customers and resellers, warning them of a design flaw in their Duplicator i3 that may cause fires. The printers suffered from an issue that caused crimp connections of the nozzle heater cartridge’s supply line to fail due to the mechanical stress in the cable drag chain. In their “Recall” titled note, Wanhao provides instructions on how to fix the issue.

Now, [Chuck Hellebuyck] released an unboxing video on the Duplicator i3 Plus, during which the heated bed emitted ~~magic~~ smoke that could be rationally explained as another design flaw.

3D Printering: Aramid And Carbon Fiber Infused ABS

September 15, 2016 by Moritz Walter 43 Comments

Last week, we had a look at a carbon-infused PETG filament. This week, I’d like to show you two composites based on a more common thermoplastic in 3D printing: ABS. Among a whole lot of other engineering plastics, the french company Nanovia manufactures Kevlar-like aramid-fiber-infused and carbon-fiber-infused ABS 3D printing filaments. These materials promise tougher parts with less warping while being just as easy to print as regular ABS. Let’s check them out!

Mega-Plate Petri-Dish Lets You Watch The Evolution Of Bacteria

September 14, 2016 by Moritz Walter 49 Comments

Rearchers of the Harvard Medical School built a 2 feet by 4 feet (61 x 122 cm) large petri-dish to visualize the evolution of bacteria. Their experiment induces mutations in E. coli bacteria by exposing them to gradually increasing concentrations of antibiotics.

Bewegungsfelder Is A Wireless IMU Motion Capturing System

September 13, 2016 by Moritz Walter 24 Comments

For several years, hackers have been exploring inertial measurement units (IMUs) as cheap sensors for motion capturing. [Ivo Herzig’s] final Diploma project “Bewegungsfelder” takes the concept of IMU-based MoCap one step further with a freely configurable motion capturing system based on strap-on, WiFi-enabled IMU modules.

Sewbo Robot Sews Up Automated Garment Manufacturing

September 12, 2016 by Moritz Walter 42 Comments

While robots enter other industries in herds, the assembly of garments has long been a tedious, human privilege. Now, for the first time, a robot has sewn an entire, wearable piece of garment. Sewbo, an industrial robot programmed to tackle the tricky task, assembles clothes and makes it look easy.

Building An Electric Longboard From Scratch

September 11, 2016 by Moritz Walter 7 Comments

Step one to most electric longboard builds is typically the acquisition of a foot operated longboard, with step two being the purchase of a ready-made motor bracket to electro-convert the strenuous vehicle. Not so [Matt Carl’s] scratch-built electric longboard, which starts out with four 1/8″sheets of baltic birch.
